Introduction
Lockheed Martin Corporation has prepared this Groundwater Surveying and Sampling Report to
describe the methodology and results of the sampling of existing groundwater monitoring wells
conducted in March 1999 at Martin State Airport, Middle River, Maryland. This field work
was the first in a series of tasks that wíll be completed in support of a risk based evaluation of
the southeast portion of the airport. The objective of the well sampling was to obtain updated
chemical data on groundwater quality from six existing groundwater monitoring wells and one
piezometer located at the site. Additionally, current data on groundwater elevation and flow
direction was collected during the sampling program.
This report is organized into the following sections:
. Section 2 - Site Background, presenting a brief description of site location, groundwater
conditions, and well construction data;
. Section 3 - Groundwater Monitoring Well Surveying and Sampling Program, presenting the
technical approach, a description of the field methodology employed, quality, and the analytical
scheme;
. Section 4 - Summary of Analytical Results, presenting the results of the laboratory analysis of the groundwater samples collected;
. Section 5 - Groundwater Elevation Data, presenting groundwater contour map and gradients
based on groundwater elevation measurements and well survey data; and
. Section 6 - Local Groundwater Well Information, presenting data provided from the Maryland Department of the Environment (MDE) on groundwater wells in the
area.

Section 2
Site Background
2.1 SITE LOCATION
The well sampling area is located at the southeast portion of the Martin State Airport in Middle
River, Maryland - see Figure 2-1. Frog Mortar Creek is located east of the well sampling area and
flows into Chesapeake Bay.
2.2 SITE GROUNDWATER CONDITIONS
Previous monitoring well measurements (recorded in February 22, 1996) documented groundwater
at depths ranging from approximately 6 to 20 teet below ground surface (bgs). Groundwater
elevation measurements indicated flow direction toward Frog MOItar Creek. The direction of
groundwater flow measured during this sampling program was consistent with historical site
investigation data.
2.3 WELL CONSTRUCTION DATA
From 1994 to 1996, a total of three flush-mounted piezometers and six monitoring wells (three f1ush-
mounted and three stick-up) have bæn installed at the southeast portion of Martin State Airport.
However, during a site walk conducted in December 1998, only one piezometer (PZ-2) was able to
be located - see Figure 3-1 for well locations. Airport persormel mentioned that considerable storm
water drainage work with heavy equipment was conducted in the area between the runway and

Taxiway Tango during 1997. It is assumed that piezometers PZ-I and PZ-3 may have been
destroyed or buried during this grading activity. In addition, it was observed during the site walk
that monitoring well MW-I, also located between the runway and Taxiway Tango, was damaged.
Originally installed as a flush-mounted well, the protective casing of this well has been lifted
approximately I-foot above ground level and is tilted towards the northwest. It appears that this well
was struck by a bulldozer or grader. The top of the pve casing was not visible and therefore
groundwater elevation data from this well is not considered reliable.
Table 2-1 summarizes the well construction data for the piezometer and six monitoring wells.

Groundwater Monitoring Well
Surveying and Sampling Program
3.1 TECHNICAL APPROACH
The purpose of the groundwater sampling is to provide current data on groundwater quality at
six existing wells and a piezometer located within the southeast portion of Martin State Airport.
The objective of the well surveying is to obtain updated data on the direction and gradient of
groundwater flow. The locations of the groundwater monitoring wells and piezometers are
shown in Figure 3-1. The details of the field methodologies utilized and analytical scheme are
presented in Sections 3.1.1 to 3.1.6.
3.1.1 Well Surveying
Each mOlútoring well and piezometer location was surveyed by a surveyor licensed in Maryland.
The elevations were surveyed at a notched reference point at the top of the inside well casing. This
notch was also used as the reference point for measuring groundwater depths. Elevations of the top
of each casing were surveyed at the reference point to the nearest 0.01 foot and elevations of the
ground surface were measured to the nearest 0.1 foot, both referenced to mean sea level (MSL).
The horizontal location of each well centerpoint was surveyed to the nearest 0.1 foot. All survey
data is referenced to the Maryland State Plane Coordinate System. A summary of the data obtained
from the survey is presented in Table 3-1.

3.1.2 Water Level Measurement
Prior to any well purgmg or sampling, a complete round of water level measurements was
conducted using a water level meter (groundwater depths were measured in all seven wells within
15 hours). Additionally, before purging or sampling of each well was performed, the water level in
the well was measured. The water level meter consists of a liquid sensor attached to a measuring
tape that is lowered down into the well until water is encountered. A buzzer sounds when the probe
reaches groundwater and the depth is read from the tape relative to the notch in the top of the well
casing. Water level measurements for each well were recorded in the field logbook.
3.1.3 Well Purging
Prior to collecting a sample, each well was purged to ensure that representative samples of the
surrounding formation waters were collected for chemical analysis. The well purging consisted
of removing approximately three to six casing volumes of water from the well prior to
sampling. Casing volumes were calculated by first measuring the depth to groundwater and
then measuring the total depth of the well. The resulting height of the water column was then
multiplied by a conversion factor to determine the number of gallons in one casing volume.
LMC: MARTIN STATE AIRPORT. GROUNDWATER MONITORING WEll SURVEYING AND SAMPLING REPORT PAGE 3.3
A down-hole submersible pump was used to purge the monitoring wells, while a hand bailer
was used to purge piezometer PZ-2. Purged water was stored in 55-gallon drums labeled
according to corresponding well number. These drums are currently stored onsite in a secure
area and their contents will be disposed of at an approved disposal facility, based on the
groundwater analytical results presented in Section 4.
During well purging, the groundwater physical parameters of temperature, pH, conductivity,
and turbidity were measured using a flow-through water quality monitoring system.
Stabilization of these parameters serves as an indicator of adequate purging in preparation for
collection of a representative groundwater sample. Table 3-1 summarizes the final readings for
each parameter prior to sample collection. The monitoring data was recorded on field data logs
- see Appendix A.

PZ-2 3-17-99/ll07 - 9 gallons 13.4 5.87 78.4 0.596
3.1.4 Groundwater Sample Collection
Once at least three well volumes had been purged and the physical parameters described in Section
3.1.3 stabilized, one groundwater sample was collected from each of the six monitoring wells and the
piezometer. Samples were transferred directly from the pre-decontaminated, disposable polyethylene
lMC; MARTIN STATE AIRPORT, GROUNDWATER MONITORING WElt SURVEYING AND SAMPLING REPORT PAGE 3-4
bailers into laboratory-prepared sample containers and immediately placed on ice in a cooler. At the
end of each day's sampling activities, samples were transported to Gascoyne Laboratories, a
Maryland State-Certified laboratory, for analysis.
3.1.5 Laboratory Analyses
All groundwater samples were recorded on chain-of-custody forms tbat accompanied the
samples to the laboratory. Groundwater samples were analyzed for the following analytical
parameters:
· Total Petroleum Hydrocarbons - gas and diesel using EPA Method 8015 Modified
· Volatile Organic Compounds (VOCs) using EPA Method 8260B
· Semi-Volatile Organic Compounds (SVOCs) using EPA Method 827OC, and
· Total Priority Pollutant Metals using EPA Method 6020/7470A.
· Dissolved Priority Pollutant Metals using EPA Method 6020/7470A.
Quality control samples (trip blanks and field duplicate) were also delivered to the laboratory.
The trip blanks were provided by the laboratory and accompanied all VOC samples. The field
duplicate (labeled MW-7) was collected from monitoring well MW-5.
3.1.6 Field Quality Assurance I Quality Control Procedures
Field quality assurance and quality control procedures included the following actions that
minimized the potential for cross-contamination:
. The well purging equipment was washed in a solution of Alconox and clean tap water,
rinsed in clean tap water, and then rinsed in distilled water between each sample.
. A new, pre-decontaminated polyethylene bailer was used to collect each groundwater
sample.
. Clean, laboratory-prepared containers were used for each sample.

3.1.7 Field Notes I Documentation Procedures
In addition to a field notebook, which was used to record the daily log of site activities, the
following forms were used to record data generated in the field:
. Daily Record of Work Progress: This form was used to record names of project
personnel on the site, equipment on-site, materials delivered to the job, items of work
completed, and a daily summary.
. Calibration Forms: An instrument-specific form was used to record calibration data.
Data was entered at the beginning and end of each day.
. Well Log: This form was used to record specific conductivity, pH, temperature, and
turbidity measurements obtained during well purging.
. Chain-of-Custody Record: This form accompanied each shipment of samples to the
laboratory to insure accountability for the samples from the time of collection to the time
they were received at the laboratory.
. Tailgate Safety Meeting: This form was used to record all safety issues discussed by the
Site Safety Officer with field personnel prior to starting work. These issues included
hazards that may be encountered during work, preventive health and safety measures,
and emergency hospital routes.

Summary of Analytical Results
A total of eight groundwater samples (including the duplicate sample) were collected from six
monitoring wells and one piewmeter to obtain updated chemical data on groundwater quality at the
southeast portion of Martin State Airport. The duplicate sample was collected from monitoring well
MW-5 and is labeled as MW-7. These samples were analyzed by Gascoyne Laboratories, Inc., a
Maryland State certified laboratory for the following parameters:
. Total Petroleum Hydrocarbons - gas and diesel using EPA Method 8015 Modified
. Volatile Organic Compounds (VOCs) using EPA Method 8260B
· Semi-Volatile Organic Compounds (SVOCs) using EPA Method 8270C, and
. Total Priority Pollutant Metals using EPA Method 6020/7470A.
· Dissolved Priority Pollutant Metals using EPA Method 6020/7470A.
The results of the sampling program are presented in this section and the laboratory analytical data
reports are presented in Appendix B.
Petrolewn Hydrocarbons
All eight samples were analyzed for both gasoline and diesel range petroleum hydrocarbons.
Gasoline was detected in two monitoring wells, MW-3 and MW-5, at concentrations of 170 ppb and
46,000 ppb, respectively. In addition, diesel was detected in four monitoring wells at concentrations
ranging from 340 ppb to 2,800 ppb. Similar gas and diesel levels were also detected in the duplicate

Section 5
Groundwater Elevation Data
In order to obtain an accurate" snapshot" of groundwater elevations and flow at the southeast portion
of Martin State Airport, prior to well purging, groundwater depths were measured in all seven wells
within a timeframe of 1.5 hours Table 5-] summarizes the data obtained from tlús round of
groundwater level measurements. As mentioned in Section 2, well MW-I was found to be damaged,
therefore groundwater elevation data from this well is not considered valid.

The groundwater elevation data are plotted on Figure 5-1, which presents groundwater flow
contours. The MW-3 groundwater elevation was not used for the contour map given the
measurements at PZ-2 and MW-4. The apparent general flow direction, easterly towards Frog
Mortar Creek, agrees with that determined in previous investigations. This is also the flow
direction that would be most likely in this hydrologic setting (groundwater flowing towards an
adjacent large surface water body).
lMC: MARTIN STATE AIRPORT, GROUNDWATER MONITORING WELL SURVEYING AND SAMPLING REPORT PAGE 5.1
By measuring the distance between two wells parallel to the now direction, the hydraulic
gradient can be determined. Using the elevation data depicted on Figure 5-1, measurements
between wells MW-2 and PZ-2, and MW-5 and PZ-2 are roughly parallel to the
groundwater now direction. Gradients of 0.0017 feet/feet and 0.0020 feet/feet, respectively,
were calculated, with an average gradient of 0.00185 feet/feet. Calculating the hydraulic
gradient between wells MW-4 and MW-S also appears to be parallel to flow, and results in a
higher gradient of 0.0028 feet/feet.

local Groundwater Well Information
The Maryland Department of the Environment (MDE) was contacted in order to obtain information
on groundwater wells in the area surrounding the site. MDE personnel conducted a search of the
MDE well log database to locate groundwater wells within approximately a one-half mile radius of
the site. A total of seventeen wells were identified, primarily in neighborhoods on the opposite side
of Frog Mortar Creek, north-northeast of the site - see Figure 6-1. A summary of the available
information on these wells is presented in Table 6-1. Only two of the seventeen wells have industrial
uses and the remainder are used for domestic pmposes. Well depths range from 50 to 199 feet.

LEGEND e Approximate locations of groundwater wells
LMC: MARTIN STATE AIRPORT, GROUNDWATER MONITORING WELL SURVEYING AND SAMPLING REPORT PAGE 6-2
Based on the estimated groundwater t10w direction presented in Section 5, these wells would not
be considered downgradient of the site. Further isolating these wells from the site is Frog
Mortar Creek, which most likely acts as a hydraulic barrier or divide between groundwater at
Martin State Airport and groundwater present on the northern side of Frog Mortar Creek.
