Water quality & impurities
EPA compliance record
Lead at the tap: 90th-percentile result 6.8 ppb in 2025 (action level 15 ppb).
EPA record: no health-based violations since 2015.
1 violation of any kind logged since 2020, 1 of them paperwork (monitoring, reporting, public notice or consumer report).
Supply stress
Lake Mohawk itself (0.79 sq mi / 507 acres, max depth 23 ft, fed by Middle Run) is a private recreational impoundment, not the water system's actual source -- the Mohawk PWS draws from separate groundwater wells near the lake. No capacity or contamination concerns for those wells were found in any source reviewed this session.
