The ZIP codes associated with Kennett Public Water System have a median household income of $55,817 and about 11,964 residents live in those ZIP codes (Census; not the number of people this system supplies). Approximately 75% of housing stock was built before 1986, which increases the likelihood of lead service lines and older plumbing.

Environmental Justice Note: On average, 90% of census tracts in the counties mapped to this service area are designated disadvantaged by the federal Climate and Economic Justice Screening Tool (CEJST, 2022 version). Communities with higher disadvantaged populations often face disproportionate environmental and health burdens, including aging water infrastructure and limited resources for remediation.

๐Ÿ’ง Where Does Your Water Come From?

Groundwater

Kennett Public Water System's water is classified in EPA records as a groundwater source. Groundwater is naturally filtered through rock and soil, but it can be vulnerable to PFAS contamination, nitrates from agriculture, and industrial chemicals that seep into the water table.

PFAS in ZIP Codes This System Serves

PFAS ("forever chemicals") have been reported in samples from water systems associated with the ZIP codes in this system's area. These results can come from other water systems serving the same ZIP codes; check the UCMR5 section for any results reported for this system. 1 detection recorded.

Health concern: Exposure to certain PFAS has been associated with some cancers and with immune and developmental effects; effects differ by compound. Many PFAS break down very slowly in the environment.
Recommended filter: An activated carbon filter certified under NSF/ANSI 53 or a reverse osmosis system certified under NSF/ANSI 58 for the PFAS listed in its certification. Find the right filter โ†’

Federal UCMR5 PFAS Monitoring: Detected

This water system was tested under the federal EPA Unregulated Contaminant Monitoring Rule (UCMR5). PFAS compounds were detected; the table compares each one with the EPA MCL where one exists (April 2024 rule, compliance required from 2029) and with this state's enforceable standard where one exists.

Latest sample

Highest analyte
PFBS: 4.5 ppt
Analyte Max detected EPA MCL (compliance required from 2029) Status
PFBS 4.5 ppt No federal MCL โ€”

EPA's April 2024 PFAS rule sets MCLs of 4 ppt for PFOA and PFOS and 10 ppt for PFHxS, PFNA and HFPO-DA (GenX); water systems must comply from 2029. Other PFAS compounds have no individual federal MCL. A state standard is shown only where this system's state has its own enforceable PFAS limit. Detection results are EPA UCMR5 samples, not a measurement at your tap.

Kennett Public Water System serves approximately 10,200 people with drinking water across 1 ZIP code.
What is Kennett Public Water System's water source? ▼
Kennett Public Water System draws water from groundwater sources. Source type affects which contaminants are most likely to be present.
Is there lead in Kennett Public Water System's water? ▼
The most recent 90th-percentile lead result on record is 0.0011 mg/L (sample period ending 2024-12-31). This is at or below the EPA lead action level, which triggers system action and is not a safe level; the EPA health goal for lead is zero.
What is the demographic profile of the ZIP codes associated with Kennett Public Water System? ▼
The ZIP codes mapped to Kennett Public Water System have a median household income of $55,817 (Census ZIP-code estimate).

Where does Kennett Public Water System get its water? ▼
Kennett Public Water System's water is classified in EPA records as a groundwater source.
