Frequently Asked Questions
Is Bridgeport tap water safe to drink in 2026?
Bridgeport’s tap water meets federal and state drinking water standards, but independent testing reveals significant concerns. While Aquarion Water Company sources water from eight protected reservoirs and well fields with comprehensive treatment, recent data shows multiple contaminants exceeding health-based guidelines.
Environmental Working Group testing found 14 contaminants above health guidelines, including total trihalomethanes at 349 times safe levels and haloacetic acids at 968 times health guidelines. While legally compliant, residents — particularly pregnant women, infants, and those with compromised immune systems — may want to consider additional filtration for drinking and cooking water. Our water filter guide covers the best options for Bridgeport’s contamination profile.
What about PFAS “forever chemicals” in Bridgeport’s water?
PFAS have been detected in Bridgeport’s water supply. Testing shows PFOA at 1.66 ppt (approximately 18 times above EWG health guidelines) and PFOS at 0.893 ppt (approximately 3 times above health guidelines). Aquarion has been voluntarily monitoring for PFAS since 2019.
Under EPA’s landmark PFAS rule finalised in April 2024, legal maximum contaminant levels of 4 ppt for both PFOA and PFOS have been established — the first federal drinking water standards ever set for these compounds. Utilities must complete initial monitoring by 2027 and achieve treatment compliance by 2029. Current Bridgeport levels are below the new federal MCLs but remain above health-based guidelines. This is a Connecticut-wide issue, with dozens of public water systems showing PFAS detection under expanded UCMR5 monitoring.
Does Bridgeport have lead in its water system?
Aquarion Water Company maintains compliance with federal and state regulations for lead and copper in drinking water:
• System compliance: Regular lead and copper monitoring shows levels below EPA action limits throughout the Greater Bridgeport System
• Corrosion control: Water treatment includes corrosion inhibitors and pH optimisation to prevent leaching of metals from internal plumbing systems
• Service line information: Customers can use Aquarion’s interactive map or service line survey tool to check their service connection material by address
• Testing resources: Contact Aquarion’s Water Quality Department at 1-800-832-2373 for water quality testing information specific to your property
Homes built before 1986 in Bridgeport and across Connecticut have a higher likelihood of containing lead components in internal plumbing, making monitoring and point-of-use testing important for older properties regardless of utility compliance status.
Are there water restrictions in Bridgeport?
Aquarion Water Company implements seasonal conservation measures and irrigation schedules throughout their service territory:
Irrigation Guidelines:
• Specific communities in Aquarion’s service area have mandatory sprinkler irrigation schedules during peak season, typically May through September
• Conservation programmes help reduce demand and protect reservoir levels during summer months when source water organic content is highest — directly reducing disinfection byproduct formation
• Exemptions are available for new plantings or sod installation with proper advance notification
Conservation Resources:
• Water-efficient landscaping tips and rebate programmes available at aquarionwater.com
• Educational resources on reducing outdoor water use and protecting watershed sources from contamination
Current conservation measures and specific restrictions are available at aquarionwater.com or by calling 1-800-732-9678. For emergency advisories, check our live U.S. boil water advisory tracker.

Contaminants of Concern
Disinfection Byproducts
Source: Formed when chlorine disinfectants react with naturally occurring organic matter in source water from the eight-reservoir system. Levels vary seasonally and are a significant, persistent concern in Bridgeport’s treatment process
Health Effects: Long-term exposure to elevated levels may increase risk of bladder, colon, and rectal cancers, liver and kidney damage, and reproductive issues; some compounds are also linked to complications during pregnancy
Current Levels: Total trihalomethanes at 52.4 ppb (349x above EWG health guidelines) and haloacetic acids (HAA9) at 58.1 ppb (968x above health guidelines). EPA Legal Limits: 80 ppb for TTHMs and 60 ppb for HAA5 — Bridgeport is below legal limits but far above health-based guidelines. See our filter guide for NSF-53 certified options that reduce these compounds.
PFAS Compounds
Source: Per- and polyfluoroalkyl substances originating from industrial processes, firefighting foams, and consumer products that have entered reservoir and well water sources throughout Connecticut via surface water runoff and groundwater migration
Health Effects: Research links PFAS exposure to immune system suppression, thyroid dysfunction, elevated cholesterol, certain cancers (kidney and testicular), pregnancy complications, and liver damage. Health effects may be more pronounced in children and during foetal development
Current Status: PFOA detected at 1.66 ppt (approximately 18x above EWG health guidelines) and PFOS at 0.893 ppt (approximately 3x above health guidelines). Additional PFAS compounds including PFBA and PFHxA have also been detected. New Federal MCLs: EPA’s April 2024 rule sets 4 ppt limits for PFOA and PFOS, with compliance required by 2029. Bridgeport is currently below these MCLs but above health-based protective levels.
