ABSTRACT
The chemical composition of bottom sediments and their associated pore waters from the tidal Potomac River and Estuary was studied from May 1978 through June 1980. Pore waters were routinely analyzed for pH, Eh, alkalinity, and concentrations of sulfide, sulfate, phosphate, carbon, ammonium, silica, iron, manganese, chloride, sodium, potassium, calcium, and magnesium. Porosity, weight loss on ignition, and carbon, nitrogen, and phosphorus contents were determined for the solid sediments. The range of salinity and chemical compo sition encountered in the estuary frequently necessitated modifications of standard methods of analysis. Therefore, the methods used, their modifications, and their limitations are presented in some detail. The appendix lists the data obtained during six sampling periods.
INTRODUCTION
From June 1977 to September 1982, the U.S. Geological Survey conducted a study of the tidal Potomac River and Estuary. One part of that study was an investigation of the chemical composition of the bottom sediments and their associated pore waters. The investigation examined both spatial and seasonal variation over a three-year period. The data from this investigation are presented in the Appendix. The body of this report presents the methods which were used to obtain the data. Although many of the methods are standard and commonly employed, they are presented here in some detail for two reasons. The first is that the wide range of salinities encountered in the estuary ne cessitated many modifications of the methods. It is hoped that presentation of these modifications will be useful to others undertaking sediment chemistry studies in estuaries. The second reason for the detailed presentation is that even standard methods have limitations and can present problems when applied to as heterogeneous an environment as estuarine sediment. It is important that these limitations and problems be clearly stated for those who will use and interpret these data.
Station Locations
The locations of all stations are presented in figures 1-3. Cores are designated by both the site from which they were taken and the cruise during which that station was occupied. The first letter of the site designation, V or J, indicates the ship from which the core was taken, either the R/V Venus or the R/V Judith Ann, respectively. At the end of August 1978, three stations were sampled which were labelled HI, H2, and H3. The H represents an associated investigator, Douglas E. Hammond, although the R/V Venus was the ship from which the sampling was done. The cruises are represented by two numerals for the year of the cruise, followed by two numerals for the month of the cruise (e.g., 7809 represents a cruise in September 1978). The cruise dates are as listed in table 1.
During September 1978, two to four cores were taken at each station, as indicated by the letters A, B, C, and D after the station number. A central buoy was placed and cores were retrieved on a crossing pattern, each core being approximately 150 m from the central buoy. In addition to providing information on seasonal changes that occurred between May and September, this procedure allowed us to determine the spatial variability at the sites.

METHODS OF ANALYSIS
Field Sampling Techniques
The cores examined in this study were taken either with a ship-operated Benthos 1 gravity coring device, Model 2171, or manually by divers using self- contained underwater breathing apparatus (SCUBA). In both cases, cellulose acetate butyrate core liners with a 6.7-cm inner diameter were used. A ship-operated corer made it possible to work safely in waters of the upper part of the tidal Potomac River which are directly affected by the sewage treatment plants. The disadvantages of the ship-board corer were that it was not possible to know the angle of penetration and that the corer had to be dropped into the sediment with some force, thus disturbing the surface of the sediment. Divers could insure vertical penetration and less disturbance of

the sediment. Manual retrieval of cores by divers was hampered by poor visibility and highly compacted sediments at some locations. Sandy sediments and sediments containing or overlain by oyster shells or large quantities of undecomposed detrital material, such as leaves and sticks, precluded manual and mechanical sampling or extrusion of the cores and therefore were not sampled.
Once on board, the cores were capped and stored upright in a box supplied with a continuous flow of river water to maintain the ambient water temperature. The entire sampling operation required 5 hours. No core was stored for longer than 5 hours before being processed.
Cores were processed in two anaerobic glove boxes that were connected with a flexible rubber sleeve. Prior to extruding the core, both boxes were purged with nitrogen gas for a minimum of one-half hour then maintained with a constant positive pressure of nitrogen gas during processing. The core was inserted into one glove box through a port in the bottom. A piston, made either of rubber or plexiglass with rubber o-rings, was placed into the bottom of the core liner. Water overlying the sediment was removed with a peristaltic pump and chilled for later analysis. Hydraulic pressure against the piston allowed the core to be extruded directly into nylon squeezers (Reeburgh, 1967) which were kept refrigerated until the time of use. The usual sampling intervals were 0-2, 2-4, 4-6, 6-8, 8-10, 15-17.5, 25-27.5, 35-37.5, 45-47.5 and 65-67.5 cm. The increase from 2-cm to 2.5-cm intervals at 15 cm and beyond was necessitated by the reduced porosity of the core with depth and consequent difficulty in expressing a sufficient volume of pore water.
Electrode measurements were made by direct insertion of the electrodes into the sediment before the water was extracted. A second set of electrode measurements, made on expressed pore water, is discussed below. The four electrodes (pH glass, platinum, silver/silver sulfide, and double junction reference) were secured in a plastic holder and inserted into the sediment. Specifics of the electrode measurements are described in the analytical methods section.
The three-piece nylon squeezers, modelled after Reeburgh's design (1967), were fitted with o-ring seals. Pore water was expressed by the pressure of nitrogen gas against a sheet of dental dam rubber which covered the sediment.
During May 1978, September 1978, and March 1979, the pore water was passed through an 82-mm diameter, 0.1- ym pore-size Millipore membrane filter. From August 1979 until the end of the study, 0.22- ym poresize Millipore membrane filters were used. The membrane filter was placed over a Schleicher and Schuell No. 589 Black Ribbon paper filter. The water was expressed through a Swagelok fitting directly into a 30-mL plastic syringe. Most sediment intervals provided from 20 to 30 mL of water and 15 minutes to 1 hour were required to complete the squeezing. The first 1 to 2 ml of water were not collected in the syringe because of possible contamination as discussed below.
Approximately 3.5 mL of the expressed pore water were injected into a plexiglass cell which contained a second set of the same four electrodes that were used for the insertion into the sediment. The electrodes were flushed by repeatedly injecting and withdrawing the pore water. The water was dis carded and the cell was rinsed with distilled water and wiped dry after each sample was completed. The discarded water was sometimes used for sulfate measurements.
Samples to be analyzed for alkalinity, phosphate, chloride, ammonium, sulfate, organic carbon, inorganic carbon, sulfide, and the major cations,K , Na , Ca , and Mg were stored in borosilicate glass vials with Poly- Seal caps. The samples for silica, iron, and manganese were stored in linear polyethylene vials with Poly-Seal caps. The samples for iron and manganese were acidified to a pH of less than 2 with J. T. Baker Ultrex concentrated hydrochloric acid. The 2- to 8-mL samples required from 0.05 to 0.150 mL of acid to achieve the proper pH and to remove the yellow color indicative of iron oxyhydroxides. Acidification was especially important in the tidal river where iron levels were highest. A second 1 mL iron sample was placed in a borosilicate-glass snap-cap vial for analysis by the Hach Company FerroZine method. Fifty uL of the reducing agent hydroxylamine hydrochloride was added to this sample on shipboard. Brinkmann Eppendorf pipettes were used for all sample transfers and reagent additions.
The sediment remaining in the squeezer after expressing the pore water was placed in plastic Whirl-Pak bags and frozen for shipment back to the lab oratory. The pore-water samples were chilled with a commercially available reusable ice substitute. The pore-water samples were not allowed to freeze. The total time required for coring, sample processing, and transport back to the laboratory was 12 to 16 hours.
The membrane filters were investigated for background contamination. The 0.22- urn pore-size Millipore filters gave blanks of 60 nmol Cl~, and 6 nmol SO, ̂ ~ when 100 mL of distilled water was passed through them. These values are both several orders of magnitude below the levels of these constituents in the pore waters. Other investigators have determined background levels for Millipore membrane filters for total organic carbon, nitrate, chemicaloxygen demand (Hwang and others, 1979), and Ca , Mg , Na , Si02, total dissolved phosphorus, and total dissolved nitrogen (Wageman and Graham, 1974). The results were not included here, however, because the Millipore filters tested were different in both pore size and diameter from those used in this study.
The changes in the pore-water carbon concentration during squeezing were investigated by Sheila Boulay (written communication, August 9, 1978). The most significant source of contamination was found to be the Millipore membrane filter. The paper filter was found to be a less important source of contamina tion. The results, which are presented in figure 4, indicate that the contam ination is most severe for the first five 1-mL aliquots. Additional testing (fig. 4) suggested that the first milliliter expressed from the sediment can have concentrations five times as high as the sample taken as a whole. For this reason, the first 1 to 3 mL were discarded before attaching the syringes for sample collection.

Experiments were performed during October 1979 to determine if there were any changes in the concentrations of NH^ , alkalinity, or SiC^ during squeezing. Three cores were taken from site JQ downstream from Quantico. The pore water from two of the cores, JQA and JQC, was partitioned into three consecutive fractions (A, B, and C) of 7 ml each. The results are presented in table 2. The sediment intervals were placed into the squeezer in such a way that the uppermost portion of any interval was at the bottom of the squeezer. For both silica and alkalinity, the increase with each successive aliquot parallels the increase down the core. This suggests that the pore water is being forced out of the interval with very little mixing, and that the water nearest the bottom of the squeezer (which is the top of the interval) is expressed first. Ammonium does not show the same pattern. Although ammonium concentrations increase with depth, concentrations in successive fractions from the same interval tend to decrease.
Chemical Analyses
The following sections describe the analytical methods used in this study. In some cases, more than one technique was used, and in others, the literature method was modified. The reasons for these changes are discussed. Table 3 lists the methods of analysis for determined species.
ELECTRODE METHODS
The pH of sediment pore waters was measured two ways: (1) by insertion of electrodes into the sediment after extrusion but before squeezing, called the sediment pH, and (2) on expressed pore water that was transferred to the plexiglass electrode cell, called the cell pH.
The following pH meters were used during the indicated sampling times: Orion 701 pH meter (cruises 7805 and 7809), Chemtrix 60A (7903), and Corning 125 (7908 and after). All pH measurements were made using Orion pH electrodes (model 91-01-00) with Ag/AgCl internal references and Orion double junction reference electrodes (model 90-02-00). The inner filling solution (Orion 90-00-02) and outer filling solution (Orion 90-00-03, 10% KN03) of the reference electrode were changed daily. In locations with significant concentrations of H2S, the outer filling solution was changed after each core (10 samples) in an attempt to avoid the formation of highly insoluble Ag2S in the porous junction between the inner and outer filling solution or on the silver wire which is in contact with the inner solution,
Electrode pairs were calibrated with standard buffers of pH 7.00 (± 0.02 at 25°C) and pH 4.00 (± 0.02 at 25°C) before and after a set of core samples was measured. Fresh buffers were used for each core.

All measurements were made to the nearest millivolt and converted to pH units. The length of time allowed for each measurement varied from 1 to 10 minutes depending on the length of time necessary to reach a stable reading. Because of time limitations, a drift of <1 mV/minute was considered a stable reading.
The precision of the method, assuming temperature was relatively constant, was estimated by comparing the calibrations at the end of a set of measurements with those made at the beginning of the set. The precision was ± 0.05 pH units. The accuracy in terms of well-defined (buffered) solutions was estimated to be ± 0.1 pH units.
The sediment pH was measured in a relatively intact volume of sediment (60-80 cc) before squeezing. Consequently, there was less opportunity for pH errors due to sample temperature changes, oxidation, or degassing. On the other hand, the contact between the electrodes and the pore water was not uniform, there may have been sediment electrical effects, the glass membrane of the pH electrode is easily scratched, and there was usually a temperature difference between the calibration buffers and the sediment.
The cell pH measurement assured a uniform interface between electrodes and solution and close agreement between the temperature of the buffers and the temperature of the pore water. Unfortunately, the similarity in temperatures was the result of a change in pore-water temperature from in situ to shipboard temperature. In addition to temperature changes, oxidation of reduced species and degassing of dissolved species could have altered the pH of the solution.
In general, the pH was higher in the cell measurements than in the sediment measurements by 0.1 to 0.2 pH units. This pH change is at tributed to degassing of C02 and H2S according to the following equations:
H + HC03 * H20 + C02 (g ) (1)
H+ + HS~ > HS (2)
Because the partial pressures of these gases in the glove box were practically zero, this degassing would, after a period of time, essentially deplete the pore waters of bicarbonate and bisulfide if they were left in contact with the glove box atmosphere. In some instances, the pH of the cell measurements was lower than that of the sediment. There are several possible explanations for these results: (1) incomplete electrode solution equilibration, (2) oxidation of ferrous iron and precipitation of ferric hydroxide,
12H20 + 4Fe2+ -» 4Fe(OH) 3 + 12H+ (3)
or (3) temperature variation between electrodes and samples or between calibration solutions and samples.
14
Eh
The redox potential, Eh, was measured in the same two ways as the pH: (1) in the sediment and (2) in a plexiglass cell. Eh was measured in mil livolts using a platinum electrode (Beckman number 39271) and the same double junction reference electrode used for the pH measurement. Time limitations required that readings be taken after a maximum of 10 minutes even though the drift, at times, was greater than 5 mV/minute. Occasionally, it seemed that several measurements were required for the electrode to equilibrate with the reduced environment of the sediments, with sediment Eh decreasing over the first few samples for each core regardless of the order in which the samples were measured. Because of the drift and slowness of equili bration, the precision is estimated to be only ± 50 mV.
Like pH, Eh is subject to continuous change from the time of coring. Any oxygen in the glove box atmosphere or trapped within the filter will contribute to the oxidation of the reduced species, resulting in the ob served increase in Eh from the sediment measurements to the cell measure ments. The sediment appears to provide a redox buffering capacity which is absent in the pore water alone, as indicated by the following observa tions. In the lower estuary, where there was significant sulfide production in the sediments, the sediment Eh was approximately -200 mV. The cell Eh was generally about -150 mV if there was measurable sulfide in the extracted water. In the tidal river, where there are high concentrations of iron in the pore water, the sediment and cell measurements range from 0 to 100 mV. In the transition zone, the sediment Eh values are about -200 mV, but the pore-water Eh values are between 0 and 100 mV. It appears that as long as the pore water is in contact with the sediments there are small but sufficient concentrations of sulfide or an organic redox couple to produce a low Eh. After filtration, the pore water is no longer in contact with the solids and has virtually no redox buffering. Thus, the Eh rises until it reaches an equilibrium value of the iron system. The squeezing and filtering process can make as much as a 300 mV difference in the measured Eh. For these reasons, the sediment measurements are considered to be the more representative of the in situ redox potentials.
Sulfide Specific Ion Electrode
r\
The activity of the sulfide (S ) ion was measured with the Orion sulfide electrode (model 94-16A) and the Orion double junction reference electrode (model 90-02-00). Use of a double junction rather than a single junction electrode minimized the problem of precipitation of Ag2S within the junction. In addition, the filling solutions were changed frequently, as discussed in the pH section.
The electrode was calibrated in solutions saturated with hydrogen sulfide gas at one atmosphere partial pressure and at varying pH values (Berner, 1963). The sulfide electrode, the reference electrode, and a glass pH electrode were
15
enclosed in a chamber containing distilled water and an overlying head space of hydrogen sulfide gas. The chamber was vented to the atmosphere and gas slowly bubbled through the solution. Na£S and NaOH were used to vary the pH of the solution. The glass electrode had previously been calibrated in the same chamber at the same temperature. After the system reached equilibrium, the activity of sulfide (at 25 ) could be computed from the expression:
(as2-) / p = 10"21 ' 9 . (4)
To ensure equilibrium, periods of up to 1/2 hour were required for each point on the calibration curve.
Because the electrode is also responsive to silver ions, solutions of AgNOo were used to check the electrode calibration. The assumption was made that Ag is in equilibrium with Ag2S at the electrode surface. Using solutions of silver in the linear response range of the electrode, the activity of sulfide was determined from the expression:
as2- =
10-49.7
(aAg+)

where the k of Ag9 S was taken as 10 (Sillen and Kartell, 1964). Thes p £* slopes determined by the silver ion method were within 15 percent of theslopes determined from calibration with hydrogen sulfide gas in spite of the need to extrapolate over many orders of magnitude to the levels of sulfide found in anoxic estuarine sediments. The sulfide electrode was usually calibrated by the hydrogen sulfide gas method at the beginning and completion of a cruise. The silver calibration provided a convenient check on the electrode calibration during shipboard operation.
To facilitate comparison with the iodometric method, discussed in a later section, the pS2~ values determined by the sulfide electrode were used to estimate the total concentration of S2~, HS~, and H S. The dis tribution of the sulfide species was determined from the pH and pS by the following equations:

The ionic strength of the pore water from localities with measureable con centrations of sulfide ranged from 0.20 to 0.35. The range of activity coefficients was 0.66 to 0.71 for YHS~ and 0.25 to 0.30 for YS2~. Because of the uncertainties in the activity coefficients, the pH, and the dissociation constants, the total sulfide values reported from the electrode measurements should be understood to provide only a qualitative comparison with the iodometric titrations.
DISSOLVED CONSTITUENTS
Alkalinity
Two methods were used to determine the alkalinity of the pore waters during the course of this study. The first method consisted of a single addition of acid, followed by a correction to account for the excess acid added (Almgreen and Fonselius, 1976). The second method was an automated titration of unacidified sample to the bicarbonate endpoint. The first method was used on all cruises from May 1978 to March 1979. The second method was used on all subsequent cruises because of its ease of measurement and improved accuracy.
Single acid addition
This method involved the addition of a known quantity of 0.01N HC1 to reduce the pH of the sample to approximately 3.5. The pH of the sample was measured and the excess acid remaining in solution was calculated. The difference between the acid added and the excess remaining in solution was a measure of the alkalinity.

The pH is strictly the -log a +; the activity of H ions therefore was corrected to the concentration of H . This was done by determining an empirical activity coefficient for a range of pH values beyond the second equivalence point of carbonic acid. Such a calibration was carried out by titrating past the end point and recording excess acid added and pH for several additions.

The Y + for each pH was determined according to equation 10. Almgreen and Fonselius (1976) point out that a table of coefficients should be deter mined with the same electrode couple that will be used to measure the samples because liquid junction potentials vary significantly between electrode couples. Because the activity coefficient is a function of ionic strength, several sets of coefficients had to be determined to include the range of ionic strengths of the samples. Table 4 presents two abbreviated sets of coefficients determined with the same electrode couple but for samples of greatly differing ionic strengths. Equation 9 was corrected by dividing by the activity coefficient.

Both the precision and the accuracy of the method improved the closer the final pH was to the endpoint. The results of five replicates of a stand ard, which contained 16.4 meq/L of alkalinity, gave a mean of 16.0 meq/L and a standard deviation of 0.79. Five replicates of a 1.64 meq/L standard produced a mean of 1.92 meq/L and a standard deviation of 0.02. The standard deviation of the 16.4 meq/L standard was large because the final pH values for those analyses were close to 3.0. This large separation from the true equivalence point can be expected to produce a large standard deviation. The need to maintain final pH values above 3.3 must be stressed.
The alkalinity values obtained in May and September of 1978 were deter mined without making the activity correction. The maximum error was 1 meq/L when the final pH was greater than 3.3 and less than the carbonate endpoint. The error resulting from not correcting for activity was as large as 3 meq/L when the final pH was below 3.3. The true alkalinity is always lower than the reported alkalinity if the activity correction is not made. The use of this method, although it has the advantage of allowing a large number of samples to be completed in a short period of time, should be discouraged due to its inherent inaccuracy.
Automated titration
Throughout the second half of this study, alkalinity was determined with a Radiometer (RTS822) automated titration recording system, following the procedures given in the manual (Radiometer). The system allowed for the automatic addition of acid and precise measurement of pH. The equiv alence point was determined from the maximum change in pH per unit of acid titrant addition. The rate of titration could be varied over a wide range to improve precision. For this study, the rate selected allowed each titration to be completed in less than five minutes. A 1-mL sample was diluted to 5 mL with distilled water in order to completely submerge the calomel reference electrode (Radiometer E4040) and the glass electrode (Radiometer G2040B).
Five replicates of each of the Na9 COo standards gave the following £ J
means (X) and standard deviations (s. d.): 16.4 meq/L standard^ X = 16.5, s. d. = 0.008; 8.20 meq/L, X__= 8.1, s. d. - 0.005; 1.64 meq/L, X = 1.64, s. d. = 0.006; 0.164 meq/L, X = 0.166, s. d. = 0.003. The standards used were representative of the range of alkalinities found in the tidal Potomac River and Estuary. The precision of the titrations was limited by the precision of the Eppendorf pipettes used to measure the sample.
20
The end point determined from titration curves ranged from pH 4.5 to 4.3. Carbonate alkalinity can be represented as:
Garb alk= HCO~ + 2CO^~ + OH" - H+ . (12)
Other species which may contribute to the alkalinity include S2-, HS~, NH~, and the anions of some organic acids, e.g., acetate and formate.Several samples from V26 and V6 were acidified to the carbonate endpoint and then degassed with nitrogen to remove all carbonate species as C02 gas. The samples were then back titrated with NaOH to a pH of 7.5 to determine the contribution of non-carbonate species to measured alka linity. The contributions ranged between 0.3 and 1.9 meq/1. This is most likely an underestimate of the contribution because the sulfide species may have been lost during degassing.
Ammonium
Analyses for ammonium-ion concentrations were done two ways. The phenol- hypochlorite colorimetric method based on the Berthelot reaction as described by Solorzano (1969) was used for pore-water analyses during 1978 and 1979. An ammonia electrode was used for subsequent analyses.
The reaction of ammonia, hypochlorite, and phenol is described in Bolleter and others (1961), Helder and DeVries (1979), and Patton and Crouch (1977). The chromophore, indophenol, is produced by the reaction of monochloroamine with phenol in an alkaline solution.
The colorimetric reaction is affected by variation in pH and salinity, the presence of sulfide and ferrous iron, and light (Bolleter and others, 1961; Gravitz and Gleye, 1975; Helder and De Vries, 1979; Ngo and others, 1982; Koroleff, 1976; Patton and Crouch, 1977; and Solorzano, 1969).
Standards were prepared in dilutions of artificial seawater (as given by Lyman and Fleming in Horne, 1969) in the salinity ranges of the samples being analyzed. Sulfide can be removed by acidifying the sample to pH 3 and bubbling an inert gas (^) through the sample. A less rigorous, but often adequate, method is to shake the capped sample vial, then remove the cap and allow exposure to air so that H2S can outgas. This shaking and exposure to air sequence was repeated several times over a period of twenty to thirty minutes before an aliquot was removed for analysis. Samples which had con centrations of iron which would have interfered with the colorimetric analysis also had concentrations of ammonia which required dilution of the samples before analysis, thereby minimizing the interference by the iron. Because light catalyzes the reaction, the samples were stored in the dark from the time of reagent addition until absorbances were determined spectro- photometrically.
21
Because volatile amines, which may be found in sewage effluent, are the only direct interference with the ammonia electrode, (HNU Systems Inc., 1978; Gilbert and Clay, 1973), the electrode was used for interstitial water analyses after 1979. An HNU Ammonia Electrode with replaceable caps and Corning model 130 pH meter (0.1 mV resolution) were used for all ammonium analyses by electrode following the procedure described in the HNU manual (HNU Systems Inc., 1978).
Sulfate
Sulfate concentrations in the pore water were determined by the ion exchange-titrimetric method of Dollman (1968). The anions of the sample were converted to their acid forms by passage through an ion-exchange column. Volatile acids were removed during two selective evaporations and the remaining sulfuric acid was titrated with sodium hydroxide.
The exchange resin (Bio-Rad AG50W-X8 100-200 mesh) was used in the hydro gen form. A column with an 8-mm diameter and packed 80 mm deep had approxi mately 30 meq of exchange capacity. The column was not allowed to go to dryness and could be used for three samples before being regenerated with 25 mL of IN HC1 and 25 mL of distilled water. The sample volume was kept close to 5 mL, depending upon availability.
After being placed on the column, the sample was eluted with four 5-mL rinses of distilled water. The eluent was evaporated to 3 mL under an infrared lamp, but was not allowed to boil. This required 1-1/2 hours. The sample was then taken to dryness in a 75° oven, which required 2 to 2-1/2 hours.
The sample was transferred to the titration vessel with three distilled water washes of 3 mL each. A solution of 0.1N NaOH was then used to titrate the sample to an endpoint of pH 7. Bromothymol blue or a microelectrode system was used to indicate the endpoint. A 2-mL Gilmont microburette was used for the titration. Interference from atmospheric C02 was prevented by bubbling nitrogen gas through the sample during the titration.
The sample was not allowed to go to dryness under the infrared lamps and the temperature of the oven never exceeded 80°C, because in either case sulfuric acid would have been lost. Phosphoric acid is less volatile than sulfuric acid and will interfere with the determination. The data in the appendix of this report have not been corrected for phosphate interference because the phosphate was only a small percentage of the sulfate present. Non-volatile acidic anions such as arsenate, chromate, molybdate, and borate will also interfere. None of these were believed to be present in appreciable quantities in the reported samples.
The samples required 5 to 6 hours to analyze. Two blanks were carried through with each set of samples. Overall, the method was found to be time consuming and sulfate is presently being measured by ion exchange chroma- tography, as discussed in a later section.
22
Sulfide
2 Concentrations of dissolved sulfide species (tUS, HS , S ) were measured
using three methods. A specific ion electrode was used to measure S (as de tailed in the electrode section), and a spectrophotometric method and an iodo- metric titration were used to determine the total of all three dissolved sulfide species.
Samples collected in May 1978 were analyzed for dissolved sulfide by the spectrophotometric determination presented by Cline (1969). Because of the wide range of sulfide concentrations encountered in the Potomac River Estuary, standards were prepared in four concentration ranges resulting in four calibra tion curves. The preparation of accurate dissolved sulfide standards from Na? S*9H?0 was difficult due to the hygroscopic nature and the fairly rapid oxidation of the reagent.
In September of 1978, and for all subsequent cruises, samples were analyzed iodometrically. Iodine was added in excess to the sample and reduced by the dis solved sulfide present. Thiosulfate was used to titrate the iodine which had not been reduced. The procedure followed was that given in Skougstad and others (1979).
To analyze for dissolved sulfide in the small volume of pore water available, the amounts of reagents added were reduced. The 1-mL samples were preserved at the time of collection with 1 mL of IN Zn(C2HoC>2)2 solution. The sample was acidified at the time of analysis with 1 mL of concentrated HCl. The iodine solution was added to the sample, 1 mL at a time, until the iodine color persisted (generally within 1 to 2 mL). A Gilmont microburette was used to titrate the sample with thiosulfate to the starch endpoint. This procedure determined the sum of2_ the three dissolved sulfide species common in natural waters (t^S, HS , S ).
Phosphorus
Soluble reactive phosphorus concentrations in pore-water samples of the Potomac River sediments were measured colorimetrically for samples collected through November of 1979 and by ion chromatographic techniques for samples collected after that time. Soluble reactive phosphorus concentrations in core-top waters were determined colorimetrically for all samples due to the lower limit of detection provided by this method.
The colorimetric method of Murphy and Riley (1962) was used. Orthophos- phate is converted to phosphomolybdate by an acidified ammonium molybdate solution and is reduced by ascorbic acid in the presence of antimony, producing a blue complex which has a maximum absorbance at 882 nm on a spectrophotometer (Skougstad and others, 1979).
23
Pore-water samples collected during the August 1978 cruise were tested for the loss of phosphate to their containers. The differences between the phosphate concentrations of aliquots of samples stored in glass versus those in plastic containers ranged from 0 to 14 percent for samples collected from a fresh-water location (with relatively low phosphate levels) and from 0 to 2 percent for samples from a saline site (with relatively high phosphate levels). (It should be noted here that the designation of sample sets by the salinity or freshness of their location is not meant to imply that the salinity or lack thereof is responsible for any differences observed. The effect of salinity on the analysis is discussed below.) Generally, aliquots stored in plastic containers had lower phosphate concentrations.
The time of sample storage was tested for its effect on the analysis of phosphorus. Aliquots of samples from a saline location, in both glass and plastic containers, showed lower concentrations of phosphate when analyzed one day following collection as compared to aliquots analyzed the night of collection. However, a similar experiment run on samples from a fresh water site yielded varying results. Samples from both saline and fresh water sites (stations V6 and V22, respectively) were analyzed the night of collection and again approximately two months later. The concentration of phosphate in all samples decreased by 9 to 58 percent in two months. Pore-water samples from stations V22, V23, and V24 were analyzed the night of collection and again the following day. Changes in phosphate concentrations ranged in this instance from 5 to 13 percent. Although the results of these experiments were often inconsistent within a single set of samples, in general it was concluded that the samples should by stored in glass vials with Poly-Seal caps and should be analyzed the night of collection.
The pore waters often developed a yellowish color when the glass vials containing samples were exposed to sunlight. This occurred primarily at the fresh-water stations where the concentration of iron in the pore water was high. Because the products of photo-oxidation could react with and tie up available phosphate (e. g. iron phosphates), the samples were kept as dark as possible between the time of collection and analysis.
Samples were also tested for interferences from arsenic, sulfide, and salinity. Several samples were collected to be analyzed by atomic absorption spectrophotometry for their arsenic concentration. No arsenic was detected at the part per billion level. Because H2S was present in many of the pore- water samples from the sediments in the lower portion of the estuary, the effect of sulfide on the phosphate analysis was examined. Sulfide, as Na2S, does not interfere in concentrations up to 1.0 mg/L (American Public Health Association and others, 1975). Distilled water and artificial seawater standards were prepared to contain 264 ymol/L sulfide and were analyzed with the normal procedure. The differences in phosphate concentration between the samples with sulfide and those without were within the analytical error. Any differences between sulfide-containing samples made up in distilled water and those in seawater also fell within the normal analytical error. However, when samples from September 1978 (stations V3 and V6) were analyzed, there may have been some interference from sulfide, as the absorbances obtained tended to drift more for these samples than for those from other locations.
24
(The drift was usually downward.) When the vials were shaken and left uncapped for up to one hour before analysis, the drift was decreased or eliminated. Concentrations of sulfide determined with the sulfide electrode and adjusted for dilution of the sample during the phosphate analysis were commonly in excess of the 264 ymol/L concentraion used in testing for sulfide inter ference. The downward drift of the absorbances was also noted in samples whose sulfide concentrations fell slightly below 264 ymol/L, indicating that the sulfide concentrations may be higher than actually measured (if sulfide is the sole interference), or, that the problem is a combination of several factors.
The possibility of interference due to the salinity of the pore waters was checked by comparing a series of standards made up in artificial fresh water with a series made up in 50 percent artificial sea water (Home, 1969). The differences observed were within the normal analytical error. In addi tion, samples from the more saline portions of the estuary were also those with higher concentrations of phosphate and required dilution (usually at least by five) before analysis. This dilution reduced the possibility of inter ference due to the salinity of the sample. Murphy and Riley (1962) also found that the salt error using their method was less than 1 percent for the analysis of ocean water.
Samples were checked for the length of time required for color develop ment. Murphy and Riley (1962) found the minimum time required for color development to be 10 minutes and that the color was then stable for at least 24 hours. In analyzing pore waters from Potomac River sediments, however, it appeared that color development proceeded at different rates for different samples and that, after the peak absorbance was reached, the absorbance then commonly decreased. Samples from cores taken in September 1978 were analyzed for phosphate and the absorbances read on the spectrophotometer after 20 minutes, then again after all samples had been read the first time. This was repeated up to approximately one hour after addition of the mixed reagent in order to determine the peak absorbances. The peak absorbance of each sample was then used to calculate the phosphate concentrations. Although this procedure was carried out for all September 1978 samples, and for later samples analyzed colorimetrically, there is some question as to whether procedural consistency should be in the determination of maximum absorbance for each sample or in reading the absorbances of all samples following the same amount of elapsed time from addition of the mixed reagent.
Data from a number of investigators indicate that the molybdenum blue method measures compounds of phosphate other than orthophosphate (Rigler, 1968; Strickland and Parsons, 1968; Dick and Tabatabai, 1977; Chamberlain and Shapiro, 1973; Edwards and others, 1965). This may be the reason for the observation that not all samples reached maximum color development at the same time. Because the water sample is in contact with the acidic mixed reagent for a minimum of 20 minutes, it is possible that some of the more easily hydrolyzed condensed phosphates and organic phosphorus compounds may be contributing to the apparent orthophosphate concentration. Analysis of several solutions containing known concentrations of Na2?207 (sodium pyro- phosphate), (NaP03)6 (sodium metaphosphate), and ATP, but not KH2P04,
25
indicated the apparent presence of orthophosphate. If no hydrolysis of these compounds were occurring, the orthophosphate concentrations should have been zero. The absorbances of these solutions increased slowly with time, as the phosphorus compounds continued to be in contact with the mixed reagent. There fore, in using this colorimetric analysis for natural water samples, what is being measured is not, in all likelihood, just orthophosphate, but also other phosphorus compounds, and should be referred to as soluble reactive phosphorus, as suggested by Strickland and Parsons (1968).
Carbon
Dissolved carbon was measured on a Beckman Model 915 Carbon Analyzer, following the method given in the instruction manual (Beckman Instruments, Inc., 1968). Total dissolved carbon was determined by oxidizing the sample at 950° C and measuring evolved C02 by infrared spectroscopy. Dissolved inorganic carbon was determined at 250° C and dissolved organic carbon was calculated by difference. High-salinity samples poison the catalyst of the total carbon system. Because the carbon levels were high enough to require up to tenfold dilutions of the samples, poisoning was not a particular problem.
Analyses were not accepted until replicates agreed to within 2 percent. Replicates of a single dilution were usually well within this limit. The replication between different dilutions of the same sample was poorer than between replicates of a single dilution. Dilution of the sample appears to be the limit to the precision of the analysis. Samples with high dissolved iron concentrations tended to form a yellowish precipitate and exhibited a reduced precision.
During June 1980, water samples were analyzed for total dissolved carbon and dissolved inorganic carbon on an Oceanography International 0524B Total Carbon System and the QIC 0524B-HR Direct Injection Module following the procedures given in the instruction manuals (Oceanography International Corporation, a, b). The direct injection module was used to determine total dissolved carbon. All of the combustion occurred in a stream of purified oxygen and the C02 produced was carried to an infrared detector after having been stripped of water vapor. Dissolved inorganic carbon was determined on the ampule analyzing unit. A sample of 0.3 mL was injected into an ampule containing 2 mL of 10-percent phosphoric acid. A stream of nitrogen gas carried the evolved C02 to the infrared detector.
Iron and Manganese
Atomic absorption spectrophotometry method
26
Concentrations of dissolved iron and manganese were determined by standard flame atomic absorption spectrophotometric techniques (Perkin-Elmer Corporation, 1976). The spectrophotometer used was a Perkin-Elmer Model 603. The salinity of the standards was matched to that of the samples to within 5 parts per thousand and the standards were also made up in 0.1N HC1.
Pore-water samples collected for the determination of their iron and man ganese concentrations were stored in linear-polyethylene bottles. The sample size ranged from 2 to 8 mL, depending on the availability of pore water. Each sample was acidified to pH 2 or lower with 0.05 to 0.15 mL of concentrated HC1. The amount of acid added was dependent upon both the volume of the sample and the concentration of iron expected for the sample. At stations V26 and V28, the concentrations of iron present in the pore waters were high enough to cause the almost immediate precipitation of iron oxides upon the extraction of the water from the sediment (in spite of the nitrogen atmosphere present in the glove box). Therefore, acid was added to these samples in small increments until the yellow color disappeared. The final volume of acid added to these samples was generally 0.15 mL.
FerroZine method
During May 1978 and March 1979, iron was also measured using the FerroZine spectrophotometric method (Stookey, 1970). At the time of sampling, 50 yL of hydroxylamine-hydrochloride was added to a 1-mL sample as a reducing agent. In the laboratory, 200 uL of FerroZine reagent and 100 uL of acetate buffer were added to the sample. Color was allowed to develop for 15 minutes and then measured at 562 nm on a spectrophotometer. If the sample required dilu tion, an additional 50 uL of hydroxylamine-hydrochloride was added to the sample before the reagents were added.
O i iConcentrations of the four major cations in the pore waters, Mg^ , K ,
Na , and Ca , were measured by flame atomic absorption spectrophotometry, using an Instrumentation Laboratory Model 351 spectrophotometer. Standard Geological Survey methods were employed (Skougstad and others, 1979).
Chloride
Chloride concentrations were determined by a Mohr titration with (Skougstad and others, 1979). During the cruises of 1978, fluorescein was used as the indicator of excess Ag , while on subsequent cruises, K^C^Oy was used as the indicator. Iodide and bromide are also titrated as chloride, and the chloride data include these two anions. Estimates of the precision of the method are given in Skougstad and others (1979).
27
Silica
The molybdate blue method (Armstrong, 1951; Strickland and Parsons, 1968), using SnCl2 as the reducing agent, was used to determine the levels of dissolved reactive silica. At the values of pH encountered in the tidal Potomac River and Estuary, the predominant forms of silica are silicic acid (H4Si04) and polymers of silicic acid. Larger polymers appear to be unreactive toward molybdate and are not measured by the methods described (Strickland and Parsons, 1968).
The silica is complexed with molybdate at a pH of less than 2.5 (Strickland 1952) to favor the development of beta silicomolybdate. After 10 minutes, tartaric acid is added to decompose unwanted phosphorus and ammonium complexes. The addition of SnClo causes the remaining silico molybdate complex to be reduced to molybdate blue which can be measured at a wavelength of 810 nm on a spectrophotometer after 1 hour of color development. Absorbance values were found to slowly decrease after 1 hour.
Standards were made from a stock solution of sodium silicofluoride (Na2SiF^). Comparisons made between standards made from comparable amounts of Na2SiF6 and Na2Si03 suggest that 80 times more silica goes into solution from the former than the latter. Increasing levels of salinity depressed the absorbance values. Therefore, standards were prepared in dilutions of artificial seawater (Home, 1969) to match the salinities of the samples.
Samples were stored in linear polyethylene vials with Poly-Seal caps to ensure minimal evaporative losses. Avoiding the use of glass eliminated a source of silica contamination. Sulfide will interfere with the method and was removed by repeatedly shaking and exposing the samples to the atmosphere before analysis.
Ion Chromatography
In suppressed ion chromatography (1C), dissolved charged species with differing affinities for a low capacity resin are separated and move through a second resin bed which replaces the counter-ion to give an eluent with low conductivity while converting the separated sample ions to highly conducting forms for detection by a conductivity meter.
Starting in August 1979, pore-water samples were analyzed using a Dionex Model 14 Ion Chromatograph. Using the anion system, chloride, phosphate, and sulfate concentrations were determined. Samples diluted with 1C eluent were used for chloride and sulfate analysis. Cation resin (Dowex 50W 8X) saturated with AgNO-j was added to samples to remove high chloride concentra tions and provide better resolution for the determination of phosphate.
28
Silver from the resin exchanges with Na in the sample solution. Chloride is removed by precipitation as AgCl. The concentration of dissolved iron in interstitial water samples from the tidal Potomac River ranges from 0.02 to 0.93 mmol/L. These samples will precipitate iron oxyhydroxides in the alkaline anion eluent. To analyze these samples by 1C, cyanide should be added to the samples at the time of collection (Nancy Simon, written commun ication, August, 1979). To prepare the cyanide-treated aliquot, 1.0 mL of interstitial water was added to a vial containing 3.0 mL of concentrated eluent and 1.0 mL of 25 mmol/L NaCN. The concentration of NaHCO^ and ^2^3in the diluted sample was the same as the eluent in the chromatographic system. The ferro- or ferricyanide complex requires six cyanide ions per ferrous or ferric ion, and the ratio of cyanide to iron in all the samples was more than 12 to 1.
During 1979, samples were analyzed using a 500-mm anion separator column and a 1.2 mmol/L NaHC03/1.8 mmol/L Na2C03 eluent. In 1980, a 250-mm anion separator column and a 4.5 mmol/L NaHC03/3.0 mmol/L Na2C03 eluent were used. The shorter column and stronger eluent reduced analysis time from 30 to 20 minutes per sample. The use of double-deionized water (15 megohm resistivity) improved the baseline of the conductivity cell and extended the life of the columns.
SEDIMENT PROPERTIES
Porosity
Sediment samples were placed in 125-mL widemouth polypropylene jars with screw caps and frozen immediately. Each sample and jar pair was then weighed and the sample freeze-dried. After drying was complete, the sample and jar pair was reweighed. The sediment was removed from the jar, the jar was cleaned, and a weight was obtained for the jar. The porosity of the sediments was calculated using the following relationships:
VHO
VH 0 + Vsed 2
(13)
Wt (Jar + HO + sed) - Wt (Jar + sed)
________________________________________________ (14)Wt- Wf Wt Wt
(Jar + H20 + sed) - (Jar + sed) + (Jar + sed) - (Jar)
Dsed
29
where:
<J> = porosity of sediment
V = volume
Wt = weight
D = density; DH Q = 1 and Dged = 2.5 2
The value of Dsed is taken from average clay mineral densities.
Weight Loss on Ignition
Sediment weight loss on ignition was determined as part of the analysis for total phosphorus. An accurately weighed aliquot of freeze- dried, ground sediment was placed in a preweighed Coors porcelain crucible. The samples were heated in a muffle furnace for 90 minutes at 550°C, cooled to room temperature in a desiccator and reweighed. The difference between the initial weight of the aliquot of sediment and the weight after heating is the weight loss on ignition.
SOLID CONSTITUENTS
Phosphorus
The procedure for phosphorus analysis of sediments followed that recommended by Aspila and others (1976). Inorganic phosphorus concen trations were determined by a l.ON HC1 extraction of the sediments, preceded by ashing of the sample when total phosphorus was desired, and subsequent analysis of the extract for phosphate by the method of Murphy and Riley (1962).
For the determination of solid phosphorus, an accurately weighed aliquot (about 0.5 g) of freeze-dried, ground sediment was placed in a pre-weighed Coors porcelain crucible. The sample was ignited in a muffle furnace at 550°C for 90 minutes, cooled to room temperature in a desiccator, and reweighed to determine weight loss. The sediment was transferred quantitatively to a 50-mL Pyrex Erlenmeyer flask and 25 mL of 1.0 N HC1 were added. The flask was covered with Parafilm and stirred on a gyratory shaker at room temperature for 16 to 18 hours. The contents of the flask were then filtered through a Millipore 0.45 ym poresize membrane filter- The filtrate was transferred quantitatively to a 50-mL volumetric flask and diluted to volume with distilled water. The procedure for inorganic phosphorus was the same as above, except the ignition step was omitted.

The weighed sample was placed directly into the Erlenmeyer flask and extracted.
Analysis of the extract followed the procedure of Murphy and Riley (1962) but required dilution of the extract such that the concentration of HC1 was less than 0.15N.
Organic phosphorus was calculated by difference between the total and the inorganic phosphorus values.
The sediment analyzed was that from which the pore water had been expressed. Calculations showed that the phosphorus in the pore water that remained with the sediments after the squeezing process was negligible.
The recovery of phosphorus from a marine mud from the Gulf of Maine (USGS standard rock, MAG-1) was 78.9 percent of the phosphorus detected by X-ray fluorescence (Fabbi, 1976). The recovery of phosphorus from a sample of Potomac River sediment was 88.2 percent of the phosphorus detected by X-ray fluorescence. The variation between duplicate samples was generally less than 2.5 percent of the mean.
Total Nitrogen
Total nitrogen refers, in this report, to the sum of organic nitrogen plus dissolved and adsorbed ammonium ion. Total nitrogen was extracted by Kjeldahl digests prepared according to the procedure of Bremner (1965). The extracted ammonium ion was measured using an ammonia electrode (Bremner and Tabatabai, 1972; HNU Systems Inc., 1978; Powers and others, 1981). An HNU Ammonia Electrode with replaceable caps and Corning model 130 pH meter (0.1 mV resolution) were used. The analytical procedure is the method of addition as described in the HNU manual (HNU Systems Inc., 1978) modified by the use of Na2EDTA (Nancy Simon and Margaret Kennedy,written communication, March 1978). Disodiumethylenediaminetetracetic acid, Na£EDTA, which is effective in alkaline solutions as a complexer of metals, was added to the Kjeldahl extracts in the amount of 1 mg/L before the addition of the sodium hydroxide solution. Na2EDTA prevents the formation of hydroxides of copper, which is part of the Kjeldahl catalyst, and iron, which is found in the sediment. It also prevents the formation of carbonates of calcium and magnesium. A dilute HC1 solution may be used to remove deposits on the electrode membrane. However, if Na£EDTA is added to the analyte solution, the exposure of the electrode to any solution other than samples and standards is avoided. The single modification of adding Na2EDTA to the sample solutions at the time of analysis results in a rapid, sensitive method which is free of interferences.
31
Carbon
Total and organic carbon were analyzed using a Model DC-12 Leco Carbon Determinator, following the methods given in the instruction manual (Leco Corporation, 1978). The sample was combusted with oxygen at 800°C and the carbon produced was trapped on a molecular sieve at room temperature. The sieve was heated to 320 C to release the carbon dioxide which was then measured by thermal conductivity.
Overestimation of the organic carbon content may occur due to the potential combustion of carbonates. Therefore, if the sediments contain large amounts of carbonate, they must be acidified to release the carbonate from the sample prior to analysis for organic carbon. Preliminary experi mentation with acidification of the organic carbon samples in this study found that the inorganic carbonate fraction was within the analytical error of the instrument. Therefore, organic carbon analyses excluded acid treat ment.
