Chesapeake City, Virginia: drinking water report. Chesapeake is an independent city in southeastern Virginia with a population of about 250,000.
Chesapeake is an independent city in southeastern Virginia with a population of about 250,000. The city operates its own water system, drawing primarily from the Northwest River and Lake Gaston via the Virginia Beach pipeline. Chesapeake sits at the southern edge of the Hampton Roads military complex – home to Naval Station Norfolk, NAS Oceana, and numerous other installations. The Great Dismal Swamp National Wildlife Refuge occupies a large portion of the city's southern area, and the swamp's tannin-rich water influences local groundwater chemistry.
The Hampton Roads area has documented PFAS contamination from multiple military sources. According to the Virginia DEQ's 2024 PFAS investigation, NAS Oceana in neighboring Virginia Beach has confirmed PFAS contamination that has migrated into the regional aquifer system. Chesapeake's municipal wells in the northern part of the city draw from the same aquifer zone.
Chesapeake's surface water from the Northwest River carries naturally high organic matter from the surrounding swamp and forested wetlands. When treated with chlorine, this organic matter produces disinfection byproducts. A 2023 VDH compliance report noted that Chesapeake's system recorded total trihalomethane levels at 62 ppb against a limit of 80 ppb during peak summer – compliant, but with limited margin.
Chesapeake's dual-source system means your water quality depends on the proportion of river versus well water reaching your part of the distribution system on any given day.
Check your water for current monitoring data at your address. For disinfection byproducts, a carbon block filter reduces levels at the tap. For PFAS, reverse osmosis is more thorough. Our water filter guide covers both scenarios. Pull your detailed report for seasonal trends, and visit our Virginia page for statewide context.
Drinking water is one exposure route. These federal datasets also cover Chesapeake City, VA.
The EPA places Chesapeake City, VA in Zone 3 - the EPA's lowest-risk category, with a predicted average indoor radon level below 2 pCi/L. Zone maps predict an area's radon potential from geology and existing indoor readings; they say nothing about a specific house. Testing is the only way to know your own level.
33% of homes in Chesapeake City, VA were built before 1980, and 4% before 1950. Residential lead paint was banned in 1978, so housing age is the strongest available proxy for lead-paint exposure. This describes the county's housing stock, not any one home.
Modelled annual fine-particle pollution (PM2.5) in Chesapeake City, VA averages 6.9 µg/m³, within the EPA's annual standard of 9 µg/m³. These are CDC modelled county estimates rather than readings from a specific monitor.
