Fishtrap Creek Water Quality Monitoring Summary

Appendix A to City of Lynden’s 2015 Annual Report
Fishtrap Creek Water Quality Violation -- S4.F.3 Report
Background
The City of Lynden was notified by Whatcom County of water quality standard violations for fecal
coliform in Fishtrap Creek, Waters of the State. Following the S4.F protocol outlined in the NPDES Phase
II stormwater permit, the City drafted this memorandum to document the effort to identify potential
sources of fecal coliform reaching the mainstem of Fishtrap Creek and report the combined sampling
results of 3 entities.
In partnership with the Whatcom County Conservation District (CD) and Whatcom County Natural
Resources Division (County), the Fishtrap Creek focus area was initially defined as the reach from Depot
Road to Bender Road (Figure 1a) bounded by Badger Road to the north and Drayton Street to the south.
This area was subsequently extended upstream to Aaron Road (Figure 1b). Water quality sampling in
the area of question is conducted primarily by the County sponsored by a Pollution Identification and
Control (PIC) grant and the CD through the PIC program and an interlocal agreement contract with the
City of Lynden. The County also samples additional sites throughout the Fishtrap basin (Figure 2).
Through adaptive management the City and partners added additional sample sites. The City took
action to identify outfalls, mobilize crews for sampling within the stormwater system to isolate potential
illicit discharges, and to help with the County and CD efforts. Additional samples were taken in the
reach of concern at outfalls (designated as sites ending in “of”) through partnerships and the City
contractors. Thirteen sites were sampled originally by the 3 entities and 21 sites were added. The
number of sampling sites evolved over time with the discovery of new outfalls and locations of high
fecal counts. The new sites were established to better characterize water quality from outfalls,
stormdrains, and the reach from Bender to Aaron Drive. Figure 3 depicts a general schematic of the
stormdrain system sites that were sampled and where they discharge to the mainstream.
The sites were too numerous and close together to identify individually at a scale appropriate for
inclusion in this report. The CD supports an interactive water quality sampling site map that can be used
to see all the sample site locations in the Fishtrap focus area. That map is available online at:
http://wacds.maps.arcgis.com/apps/webappviewer/index.html?id=e77d3beb93664d12aa7cc402ad16a48e.
The map covers sample sites throughout the county and can be zoomed in to any location. Appendix A
provides detailed description of the location of all the sampling sites included in this report.

Initial Water Quality sampling approach
Because fecal coliform counts exceeded State standards at sites along the mainstem of Fishtrap Creek,
the City took action to address the violations and began investigating the reach directly upstream of the
high fecal counts and storm systems feeding into that reach.
The City entered into a contract with the CD to conduct additionalsampling along the mainstem. The
City mobilized contractors to accompany the CD on their routine sampling field visits and document
outfalls. Outings by contractor staff were coordinated when possible with the County sampling effort.
In addition, the City coordinated with local source control staff at the County Health Department to
target business pollution prevention educational inspections.
Fishtrap Creek Source Control Desktop Assessment
To better understand the potential pollutant sources that may be contributing to the high fecal counts in
the Fishtrap focus area, a preliminary desktop assessment, using guidance tips from the Center for
Watershed Studies Pollutant Source Control manual, was conducted. This study identified property land
use types and the presence of septic systems potentially draining to this reach. Queries were conducted
using GIS software to identify desired attributes based on the assessor’s database, and County Health
septic records.
The assessment identified 12 parcels with septic systems that are within the focus area and are listed in
Table 1 and further located in Figures 4a and 4b.

Adaptive Management of Water Quality Sampling Program
Based on the additional sampling and the results of the desktop source study, an augmented sampling
regime was adopted. Approximately 21 mainstem sites and additional outfall sites were added. Storm
system monitoring was also expanded and ammonia was added as a parameter at some of the storm
system sites.
The presence of ammonia in stormwater samples can be an indicator of the presence of sanitary sewage
however there are other potential sources. Below is a listing of possible point sources of ammonia
(available online: http://www.water-research.net/index.php/ammonia-in-groundwater-runoff-and-
streams).
• Agricultural: The primary agricultural sources include accidental releases of ammonia-rich
fertilizer during transport (because of vehicle accident, faulty hose connections, and human
error); and livestock waste (from barnyards, feedlots, pastures, and rangeland).
• Residential and Urban: Household use of ammonia-containing cleaning products, on-lot septic
systems, and improper disposal of ammonia products may contribute to nonpoint pollution.
• Point sources: The following industrial processes produce ammonia emissions and effluent:
conversion of coal to coke in coke plants, metallurgic operations, ceramic production, strip
mining, chemical synthesis (nitric acid, synthetic monomers, and plastics), waste gas treatment,
sewage treatment plants, production of ammonium nitrate explosive, refrigeration equipment,
household cleaners, oil refineries, and food processing.
Elevated levels of bacteria in the focus area have been common but not consistent. The sample results
vary across sites and time with no identifiable pattern. There is little elevation change within the City of
Lynden’s jurisdiction. This often leads to stagnant water or dry storm drain facilities. No flow or little
flow made sampling difficult at times and frequently a sample was not attainable.
The City street crews adjusted their catchbasin cleaning circuit to prioritize vactoring out the stormwater
facilities feeding into this reach. These catchbasins and storm mains had yet to reach the normal
cleaning threshold and most only had a few inches of sediment. Proactively cleaning the catchbasins
was hoped to reduce the “first flush” effect transporting pollutants into the downstream receiving
waters. The City intends to adapt the storm system cleaning schedule where practical to give priority for
cleaning areas that drain to sampling sites that have repeated high fecal counts.
Discussion of Water Quality Sampling Results
The effort to identify sources of bacteria discharging either directly or through the stormdrain system to
Fishtrap Creek was inconclusive. While most samples exceeded the water quality standard, the
concentrations were highly variable throughout the reach and over time. A longer duration sample pool
may offer more insight into the impact of seasonality on sample variability. Sporadic high fecal counts
occurred but often were followed by low counts. This would seem to indicate that there may not be
cross-connections as the high values would be more persistent if a permanent connection existed. On
the other hand, the time of sampling may not coincide with high usage from nearby residences. The
sporadic high counts could be related to a number of causes including but not limited to:
Fishtrap Creek Water Quality Monitoring Summary
12
• re-suspension into the water column of fecal loads stored in the sediments in Fishtrap Creek,
• temperature fluctuations and ultra-violet input,
• pet and bird waste deposited prior to storm events,
• septic system failure or leakage following high precipitation inputs,
• antecedent conditions, water table level or,
• intermittent or one time illicit discharge.
At this point, there is not enough data from which to develop geomeans for fecal coliform at each site.
The fact that obtaining samples from outfalls and the storm system is often difficult due to stagnant
water or dry conditions will continue to be a challenge in looking at trends. The detailed results of the
fecal coliform sampling from late August through mid-November 2015, by date and site in the focus
area, can be found in Appendix B. A summary of the findings is presented below. Three paths were
investigated:
• Understanding the upstream to downstream variance in fecal coliform counts for each sampling
event,
• Understanding site stormdrain line patterns over time, and
• Looking at changes in inputs network-wide over time and as related to precipitation.
Variations in fecal coliform samples are presented from upstream to downstream by sampling date in
Table 3. Figures 6 to 10 compare the fecal counts by sampling site and date to the water quality
standard.

Figure 10: Fishtrap Creek Focus Area Fecal Coliform Sampling Results
Stormdrain line based findings:
• Bender Road storm line fecal samples never exceeded 200 FC/100ml. The ammonia standard
was exceeded on 11/18/15 at the Daisy-a site. All other ammonia samples were low.
• Depot Road storm line fecal samples were below 200 FC/100ml except for a very high count on
9/8/15 at Depot-a. Could be septic input after rain but inconclusive as Depot-b was not tested
that day and F5a-NEof was not yet an established sampling station. Ammonia samples along
this stormdrain line were all low. Fecal results were much lower for the later sampling events
(11/9/15 and 11/28/15). These results followed the catchbasin cleaning route.
• Drayton Street storm line had very little data. As with Depot Road samples, fecal counts were
very high on 9/8/15 and very low on 11/18/15. No sample results were available in between
these dates.
Network-wide findings:
A shift appeared to have occurred in November. Results after 11/9/15 were almost all below the
standard. This may be related to catchbasin cleaning in the focus area which took place in early
November. No correlation with precipitation was obvious.
At this point, no real pattern emerged that could help identify potential sources. High fecal counts
occurred throughout the focus area but not consistently at one location. Sporadic high counts were
followed by below standard results for the next sampling event. When two entities were sampling the
same site on the same day, there were large discrepancies between the results for fecal counts. For
example, on 8/13/15 both the County and the CD sampled F6-of; the County results were 30,400
FC/100ml whereas the CD’s results were 2,400. Other comparison sampling showed similar
discrepancies. Some of this can be explained by the inconsistency associated with collecting a grab
sample of a very non-homogeneous parameter. Also, the method of analysis could play a role. In
addition, the CD sampled across a transect at F6.1where three samples were taken within minutes. The

samples varied from 1,000 FC/100ml on the southside near the bank to 600 midstream and 350 on the
northside near the bank.
Conclusions
While no clear pattern or source of high fecal counts were noted, the data suggests that water quality
violations continue to happen even if sporadically. With this in mind, the City plans to take the following
actions as a result of this investigation:
• Continue working with the County on a coordinated sampling calendar between the County and
CD/ Lynden’s efforts. Interest on storm events was targeted initially by the CD and Lynden,
however, more consistent data can be collected with a coordinated sample event calendar.
• The County uses Edge Analytical labs for analysis while the CD and Lynden use Exact Scientific.
Consistency in lab techniques would help eliminate a variable. Each entity has contracts and
work load reasons to stick with the current labs. The County has however offered to supply
duplicate samples periodically to Exact Scientific as quality assurance protocol.
• Continue to respond to dry weather outfall discharges. City staff or contractors will trace
sources of dry weather flows from the outfalls to Fishtrap Creek as practical . Notification of
outfall discharges from County and WCD sampling efforts will drive the schedule of drainage
system monitoring
• Work further with County Health to educate businesses on good housekeeping
• Work with the County to determine the status of the septic systems that may be draining to this
reach by developing a notification protocol regarding County inspections and dye test results.
• Continue to fund the Conservation District’s monitoring efforts and public education and
outreach / stewardship components.
• Investigate the cost of sampling sediment in Fishtrap Creek mainstem and prioritize locations to
bracket potential re-suspension issues.
• Review data as it is available and determine if additional adjustments and or actions need to be
taken. The County has developed an interactive map online that will allow quicker access to lab
results Whatcom County Water Quality results page and interactive
maps: http://www.co.whatcom.wa.us/2170/Water-Quality-Monitoring-Results
• Establish a protocol with the County and CD and Ecology on ERTS reporting. The first agency in
that knows of a violation should process the ERTS. Since the City has developed this
implementation plan, S4F work should not be subject to ERTS every sampling day.
• Work with DOE and EPA to be informed of Industrial Stormwater General Permit compliance
visits and enforcement issues for industries within City jurisdiction so that the City can develop
appropriate response, enforcement, or permitting actions
• Within staffing limitations, the City crew will schedule more frequent cleaning of facilities
upstream of elevated bacteria values.
