J. Pollutants Sampled: Pharmaceuticals and Personal Care Products (PPCPs), E.
coli / Enterococcus, Ammonia (nitrogen), Total Chlorine,
and Surfactants
K. Previous Enforcement Actions:
Order on Consent with Environmental Protection Agency (Docket No. CWA-AO-R01-FY16-
04, " Order ") issued September 25, 2016, pursuant to Sections 308 (a) and 309 (a) (3) of the
Clean Water Act, that provides compliance requirements for both Capacity Management
Operations and Maintenance " CMOM " for the City's sanitary sewers, as well as MS4 illicit

III. Disclaimer:
Unless otherwise noted, this report describes conditions at the facility / property as observed by EPA
inspector(s), and / or through records provided to and / or information reported to EPA inspector(s) by facility
representatives and as understood by the inspector(s). This report may not capture all operations or
activities ongoing at the time of the inspection. This report does not make final determinations on potential
areas of concern. Nothing in this report affects EPA's authorities under federal statutes and regulations to
pursue further investigation or action.
IV. Type and Purpose of Inspection(s)
The purpose of the reconnaissance inspection was to locate stormwater outfalls, associated manholes,
and / or catch basins which discharge into the Long Island Sound, Island Brook, Ash Creek, Johnson's Creek,
and the Pequonnock River, while noting appearance, presence of flow, and access requirements for one or
more sampling inspections.
The purpose of the compliance sampling inspection was to identify potential illicit connections or illegal
discharges within the City of Bridgeport, CT MS4 and Combined Sewer System that may adversely impact
the water quality in the receiving waters named above. Samples were collected from nine (9) locations in
accordance with the FSB Investigations Team Stormwater Program Plan. One (1) of the samples collected
was from a Combined Sewer Outfall (CSO). Sample sites were identified during a reconnaissance
inspection conducted on November 16, 2020.

for Station KBDR, the last precipitation event occurred on November 15, 2020, with 0.16 inches
recorded.
None of the locations visited during this inspection were field screened for test kits or the YSI meter.
Locations visited were noted for appearance, presence of flow, and access requirements.
VII. 11/17/2020 Sampling Inspection Summary
On November 17, 2020, EPA employees Michelle Coombs and Shannon Brunelle (" the EPA Inspection
Team ") conducted a compliance sampling inspection of the City of Bridgeport MS4 at the locations
described in Section VIII. They were not accompanied by any city or state representatives. The inspection
was unannounced. The inspection started at Johnson's Creek on Central Avenue and Eagle Street at
approximately 07:00 hrs. At the time of the inspection, the weather was partly cloudy and approximately
45 F.
According to the National Weather Service for Station KBDR, the last precipitation event prior to the
inspection occurred on November 15, 2020, with 0.16 inches recorded. According to the National Weather
Service, in the month (to date) of November, the City observed 1.58 inches of precipitation, which is
approximately 87% of the 30-year normal value of 1.82 inches (representing a 13% departure from the
normal). According to the US Drought Monitor, as of November 17, 2020, Fairfield County is experiencing
no drought conditions. Based on the National Oceanic and Atmospheric Administration tide predictions,
low tide was recorded at 06:14 hrs. at Station ID 8467150 Bridgeport, CT.
The sampling locations described in Section VIII were field screened using test kits for ammonia (nitrogen),
surfactants, and total chlorine, where applicable. In - situ measurements for specific conductivity, salinity,
and temperature were also measured and recorded. Samples were delivered to and analyzed for E. coli and
Enterococcus at the South - Central CT Regional Water Authority in New Haven, CT, and PPCPs at the EPA
New England Regional Laboratory (NERL) in North Chelmsford, MA. Table 1 below summarizes the
sampling and analytical data.
VIII. Description of Sampling Locations
Photographs depicting each sample location are included in Appendix A of this report.
* Eagle: A single CSO outfall approximately 30 inches in diameter located at the east end of Eagle
Street. Discharge flow was approximately 15-20 gallons per minute (gpm) into Johnson's Creek.
Sample was collected from the outfall pipe.
Soundview: Discharge was observed upwelling from below the surface of the sand and flowing
into Long Island Sound at the location where discoloration of the water can be viewed on satellite
imagery (see Appendix A). Sample was collected after digging approximately 6 inches into the
sand. Sample site is located at the Seaside Park beach, on the west side adjacent to Soundview
Drive. No outfall pipe could be seen near the upwelling area or along the rip rap.
Davidson: A single reinforced concrete outfall approximately 36 inches in diameter located at the
end of Davidson Street. Discharge was flowing at approximate 10-15 gpm into Ash Creek. Some
trash and leaf litter were observed downstream and inside the pipe. Sample was collected from the
outfall pipe.
Scofield: A singular reinforced concrete outfall approximately 36 inches in diameter located on the
southeast bank of the Scofield Avenue bridge. Discharge was flowing at approximately 10 gpm
into Ash Creek. Leaf litter and trash was observed around the opening of the pipe. Sample was
collected from the outfall pipe.
Hawley: A single reinforced concrete outfall approximately 36 inches in diameter located at the
end of Hawley Avenue near Ezra Street. Discharge was flowing at approximately greater than 50

gpm into Island Brook. Slight grey staining was observed in the pipe. Sample was collected from
the outfall pipe.
Hart: A single concrete outfall approximately 48 inches in diameter located near the corner of Hart
Street and Lindley Avenue. Discharge flow was approximately less than 1 gpm into Island Brook.
Oil sheen fragments were observed downstream of the pipe, along with some trash. Sample was
collected from the outfall pipe.
Ashley: A single reinforced concrete outfall approximately 36 inches in diameter located at the
corner of Ashley Street and Glenwood Avenue. Discharge was flowing at approximately greater
than 50 gpm into the Pequonnock River. A slight petroleum odor was detected, green algae growth
and tan colored staining was observed on the pipe and rocks downstream. The joints of the outfall
were cracked, causing discharge to flow underneath the mouth of the pipe. Sample was collected
from the outfall pipe.
Slawson: A pair of reinforced concrete outfalls, both approximately 30 inches in diameter located
at the corner of Slawson Street and Summit Street. Both outfalls were flowing, however, due to the
high depth of the water, the outfall furthest away, under the bridge, could not be accessed to sample.
This outfall was flowing at approximately 20 gpm into Island Brook. The sample was collected at
the outfall pipe downstream of the outfall under the bridge. This outfall was flowing at
approximately 5-7 gpm into Island Brook.
IBrook: In - stream sample of Island Brook collected approximately 30 feet downstream of the
" Slawson " outfall. No photograph was taken at this location.

EPA notes while there are currently no numerical standards to compare pharmaceutical results against, it is EPA's experience that acetaminophen is the single best bacterial source tracking compound of those listed above, and any detection of this compound may
indicate a source of sanitary sewage. With respect to all of the above compounds, when a sanitary sewage source is present, depending on the type of source, distance from the sample location, and the strength of the source, concentrations of these compounds may
range from the low ng / l range up to thousands of ng / L.
