Report footnotes

period: The table's test dates and printed compliance cells describe the report-period samples only.
u/uu: Copper and lead values are 90th percentile values representative of customer-sampling stagnant water; the source says no copper locations and two lead locations exceeded the applicable action level.
§/caret: The source identifies one turbidity value as the highest monthly average from treatment-plant effluent and the other as measured at representative distribution-system locations.
+: Disinfection-byproduct values are the highest locational annual averages of quarterly measurements in the distribution system; ranges are individual measurements.
#: The monthly TOC removal ratio is the ratio between actual TOC removed and TOC rule removal requirements and should be greater than 1.
UCMR: The unregulated-contaminant table shows detected compounds and points readers to EPA's UCMR information; its action-level column is source context, not a federal primary standard or current safety conclusion.

Report Context

Context attributed to the source report

These summaries are limited to the named annual report and do not assert live system, compliance, or advisory status.

What this report covers

The official Aquarion report identifies the Eastern Fairfield County System, PWS ID CT0150011, and lists Bridgeport among the communities served. The report covers 2025 testing with one 2024/2025 barium period and includes 27 substantive rows across regulated, treatment, state-required, other-monitored, and unregulated sections.

Source water and treatment context

The report describes a mostly surface-water supply drawn from eight reservoirs, supplemented by Westport and Coleytown well fields, with treatment at named Aquarion plants. It reports low-to-moderate susceptibility language from a Connecticut source-water assessment and does not turn that report-period context into a current risk conclusion.

Lead and service-line context

The report explains household plumbing and service-line responsibilities, directs customers to Aquarion's service-line inventory and testing contacts, and preserves the report's 2025 lead sample-period wording. It does not determine the material of any individual service line or tap condition.

Unregulated monitoring context

The report lists five detected PFAS-related unregulated monitoring rows with source-printed Connecticut action-level context. These are report-period monitoring results; they are not federal primary standards and do not establish a current advisory or health conclusion.

Report glossary

The report glossary defines MCL, MCLG, MRDL, MRDLG, action level, treatment technique, secondary maximum contaminant level, units, and report abbreviations.

Where to check current information

Aquarion's alerts and outages page and Connecticut DPH are the official paths to check for newer instructions or notices. This packet does not assert whether a current notice is active.

How to read the table footnotes

The report footnotes qualify sampling periods, customer-sampling action levels, turbidity measures, disinfection-byproduct measurements, TOC treatment criteria, and unregulated monitoring context.

Definitions printed in this report

MCLG: Maximum Contaminant Level Goal: the level below which there is no known or expected risk to health.
MCL: Maximum Contaminant Level: the highest level of a contaminant allowed in drinking water.
MRDL: Maximum Residual Disinfectant Level: the highest level of a disinfectant allowed in drinking water.
MRDLG: Maximum Residual Disinfectant Level Goal: the level below which there is no known or expected risk to health.
AL: Action Level: a concentration which, if exceeded, triggers treatment or other requirements.
TT: Treatment Technique: a required process intended to reduce a contaminant in drinking water.
SMCL: Secondary Maximum Contaminant Level: a standard developed to protect aesthetic qualities and not health based.
ND: Not Detected.
NA: Not Applicable.
NL: State of Connecticut customer Notification Level.
