LEWES BOARD OF PUBLIC WORKS
LEWES, DE · 9,627 people served · EPA PWSID DE0000602
LEWES BOARD OF PUBLIC WORKS (LEWES, DE), which serves about 9,627 people, has no health-based drinking-water violations on record since 2016. Its most recent lead 90th-percentile sample was 23.0 ppb, above the 15 ppb federal action level. EPA's UCMR5 program detected PFAS 'forever chemicals' in this system: PFOS (0.0095 µg/L), PFOA (0.0061 µg/L), PFHxS (0.0035 µg/L). PFOA/PFOS levels exceed the 2024 federal limit of 4 ppt (0.004 µg/L). A certified water filter can reduce these at the tap — see the certified options for each below.
What the testing found
Measured levels from EPA violation records, compared to the federal limit (MCL). The black line marks the legal limit.
Lead
1.53× the federal limitNo safe level. Damages developing brain/nervous system in children; linked to lower IQ, kidney and cardiovascular harm in adults. Usually enters water from corroding pipes/solder, not the source.
PFAS "forever chemicals"
Detected by EPA's UCMR5 monitoring. The 2024 federal limit for PFOA and PFOS is 4 ppt (0.004 µg/L).

DetectedFilters certified to clean up your water
Your water shows Lead, PFOA, PFOS, PFAS. A refrigerator filter handles the most of this in one unit — these three are independently certified for the most of your contaminants (not marketing claims):

Sources & method. Contaminant levels and violations come from EPA's Safe Drinking Water Information System (health-based violations, 2016–present); PFAS from EPA UCMR5 monitoring (2023–2025). Levels shown are the highest recorded value in the violation records; a violation means the contaminant exceeded its federal limit at the system level. Your home's water can differ from the system average. Public domain data; we are not affiliated with the EPA.
