LCA WLSA CENTRAL DIVISION serves 47,693 people in ALLENTOWN, Pennsylvania using Surface Water water sources. It has 283 recorded EPA violations, including 14 health-based violations. PFAS "forever chemicals" were detected in UCMR5 testing (5 compounds found).

Water Quality Snapshot: LCA WLSA CENTRAL DIVISION

LCA WLSA CENTRAL DIVISION is a local-owned community water system that delivers drinking water to 47,693 residents in ALLENTOWN, Pennsylvania (Lehigh County) through 18,805 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 283 total violations for this system , of which 14 (5%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 266 monitoring and reporting violations are on file. The most recent violation on record dates to 2025.

The most frequently cited contaminant at this system is Nitrate, recorded in 13 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 5 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 0.0054 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Pennsylvania, EPA tracks 7,701 public water systems serving 12,630,061 people, with 1,159,868 cumulative violations and 68,517 health-based violations on record. About 97% of systems in the state carry at least one violation, and state-wide the average per system is 150.6 violations. LCA WLSA CENTRAL DIVISION's 283 violations sit above the Pennsylvania average. Statewide, 224 of 389 UCMR5-tested systems have reported PFAS detections (57.6%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
