Description of Sampling Locations (in order of collection time) Photographs depicting each sample location are included in Appendix A of this report. Seabright1: One circular concrete outfall approximately 1.5 feet in diameter, located approximately at 104 Seabright Ave. The outfall pipe is located at the northern edge of the beach. Discharge flow was approximately less than 1 gallon per minute (" gpm ") into the Long Island Sound. Sample was collected at the mouth of the outfall. No notable odor was detected. Color was clear and turbidity was low. Some organic particulates were observed.

A crack in the concrete pipe was observed further up, where the pipe first exits the sand. Beacon1: One circular concrete outfall approximately 3 feet in diameter, located approximately at 2 Seabright Ave and at the base of a rock retaining wall by the coastline. Discharge was categorized as dripping at a various rate of discharge into the Long Island Sound. Sample was collected at the mouth of the outfall. A sour odor was detected. Color was clear - yellow and turbidity was low to medium. Floatables were observed, including some organic particulate matter. The mouth of the outfall was covered in marsh hay There was garbage observed around the outfall on all sides. Note: Not enough flow to collect adequate sample volume for PPCPs, enterococcus analysis, conductivity, salinity, and temperature. Only enough discharge to analyze for ammonia, surfactants, and total chlorine. Seasidel: One circular corrugated plastic outfall approximately 1.5 feet in diameter, located approximately adjacent to Seaside Park, on Sound View Drive, Bridgeport midway down the beach front at low tide. Discharge flow was approximately 1 gallon per minute (" gpm ") into the Long Island Sound. Sample was collected at the mouth of the outfall. No notable odor was detected. Color was clear and turbidity was low. The outfall pipe was approximately 50% submerged in beach substrate. No overt floatables were observed. A brownish film was observed collecting immediately downstream of the outfall.

An internal standard is used to monitor retention time, calculate relative response, and quantify analytes of interest. Surrogate RecoveryThe% recovery for non - target organic compounds that are spiked into all samples. Used to determine method performance. Continuing CalibrationAn analytical standard analyzed with each set of samples to verify initial calibration of the system. BatchSamples that are analyzed together with the same method, sequence and lot of reagents within the same time period. NDNot detected at or above the specified reporting limit. RLRL is the limit of detection for an analyte after any adjustment made for dilution or percent moisture. DilutionMultiplier added to detection levels (MDL) and / or sample results due to interferences and / or high concentration of target compounds. DuplicateResult from the duplicate analysis of a sample. ResultAmount of analyte found in a sample. Spike LevelAmount of analyte added to a sample Matrix Spike ResultAmount of analyte found including amount that was spiked. Matrix Spike DupAmount of analyte found in duplicate spikes including amount that was spike. Matrix Spike% Recovery% Recovery of spiked amount in sample. Matrix Spike Dup% Recovery% Recovery of spiked duplicate amount in sample. RPDRelative percent difference between Matrix Spike and Matrix Spike Duplicate. BlankMethod Blank that has been taken through all steps of the analysis. LCS% RecoveryLaboratory Control Sample percent recovery. The amount of analyte recovered from a fortified sample. Recovery LimitsA range within which specified measurements results must fall to be compliant. CCCalibration Verification Flags: H- Recovery is above the control limits L- Recovery is below the control limits B- Compound detected in the Blank P- RPD of dual column results exceeds 40% # - Sample result too high for accurate spike recovery.

Sincerely,This technical report was reviewed by Timothy Fusco David DuttaQuiltya. Juvo David DittaProject Manager Laboratory Director This report shall not be reproduced except in full, without the written approval of the laboratory Report Comments: Sample Result Flags: E- The result is estimated, above the calibration range. H- The surrogate recovery is above the control limits. L- The surrogate recovery is below the control limits. B- The compound was detected in the laboratory blank. P- The Relative Percent Difference (RPD) of dual column analyses exceeds 40%. D- The RPD between the sample and the sample duplicate is high. Sample Homogeneity may be a problem. + - The Surrogate was diluted out. * C1- The Continuing Calibration did not meet method specifications and was biased low for this analyte. Increased uncertainty is associated with the reported value which is likely to be biased low. * C2- The Continuing Calibration did not meet method specifications and was biased high for this analyte. Increased uncertainty is associated with the reported value which is likely to be biased high. * F1- The Laboratory Control Sample recovery is outside of control limits. Reported value for this analyte is likely to be biased on the low side. * F2- The Laboratory Control Sample recovery is outside of control limits. Reported value for this analyte is likely to be biased on the high side. * I- Analyte exceeds method limits from second source standard in Initial Calibration Verification (ICV). No directional bias. All results met standard operating procedures unless indicated by a data qualifier next to a sample result, or a narration in the QC report. For Percent Solids, if any of the following prep methods (3050B, 3540C, 3545A, 3550C, 5035 and 9013A) were used for samples pertaining to this report, the percent solids procedure is within that prep method. Complete Environmental Testing is only responsible for the certified testing and is not directly responsible for the integrity of the sample before laboratory receipt. ND is None Detected at or above the specified reporting limit Reporting Limit (RL) is the limit of detection for an analyte after any adjustment made for dilution or percent moisture. All analyses were performed in house unless a Reference Laboratory is listed. Samples will be disposed of 30 days after the report date.
