EAST HEMPFIELD WATER AUTH

LANDISVILLE, PA · 20,988 people served · EPA PWSID PA7360063

The bottom line

EAST HEMPFIELD WATER AUTH (LANDISVILLE, PA), which serves about 20,988 people, has recorded 1 health-based drinking-water contaminant in EPA violation records since 2016, most notably Nitrate. Its most recent lead 90th-percentile sample was 8.0 ppb, within the 15 ppb federal action level. EPA's UCMR5 program detected PFAS 'forever chemicals' in this system: PFOA (0.0077 µg/L), PFBS (0.0057 µg/L), PFOS (0.005 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.

Nitrate

1.1× the federal limit

Measured 10.8 mg/L · federal limit 10 mg/L · latest 04/01/2025 · 1 violation since 2016

Causes 'blue baby syndrome' (methemoglobinemia) in infants under 6 months; MCL 10 mg/L as N. Runoff from fertilizer, septic, manure.

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.
