EPA compliance records for Southeast Morris County Mua (PWSID: NJ1424001) in Chatham Boro-1404,Hanover Twp.-1412,Harding Twp.-1413,Mendham Twp.-1419,Morris Plains Boro-1423,Morris Twp.-1422,Morristown Town-1424, NJ show 2 health-based violations recorded in EPA SDWIS, all resolved and 8 PFAS compounds detected above the minimum reporting level in EPA UCMR 5 monitoring data (most recent sample: November 2023). UCMR 5 monitoring data shows PFOA, PFOS detected above the 2024 EPA MCL threshold in at least one sampling round. Note: the EPA PFAS rule compliance deadline is 2029 — detection above the MCL level in UCMR 5 monitoring is not a regulatory violation. All records on this page are sourced from EPA SDWIS and the UCMR 5 dataset. This is official monitoring data — not a health risk determination.
Health-Based Violation History
Source: EPA SDWIS (Safe Drinking Water Information System). A health-based violation means a contaminant exceeded the legal Maximum Contaminant Level (MCL) or a required treatment technique was not met during the violation period. Resolved violations indicate the utility returned to compliance.

Official Water Sampling Events (EPA UCMR 5)
EPA UCMR 5 monitoring conducted 18 sampling events at Southeast Morris County Mua (showing most recent 25 of 25+ events). Each event tests water drawn from a designated sampling point for PFAS compounds. Source: EPA Unregulated Contaminant Monitoring Rule 5, 2023–2025.

PFAS Compounds Detected (EPA UCMR 5)
Source: EPA UCMR 5 (Unregulated Contaminant Monitoring Rule 5, 2023–2025). These are compounds detected above the minimum reporting level at a sampling point for this utility. A compound marked above MCL was detected at a concentration exceeding the EPA Maximum Contaminant Level finalized in April 2024.
PFOA, PFOS detected above the 2024 EPA MCL threshold in UCMR 5 monitoring
This is EPA UCMR 5 surveillance data — not a regulatory compliance finding. The EPA's April 2024 PFAS rule set MCLs for PFOA (4 ppt), PFOS (4 ppt), PFNA/PFHxS/HFPO-DA (10 ppt), but water systems have until April 2029 to achieve compliance. Detection above an MCL level in UCMR 5 monitoring does not constitute a violation under current regulations.

What this does not mean
- —Violations do not indicate current non-compliance. A health-based violation that is marked resolved means the utility has returned to compliance per EPA records. Historic violations are shown for transparency, not to imply ongoing risk.
- —PFAS detections above MRL are not themselves violations. UCMR 5 monitoring is a surveillance program. Detection does not mean the utility violated a regulation. The 2024 EPA PFAS rule (MCLs for PFOA, PFOS, etc.) has a compliance deadline of 2029.
- —This page does not assess health risk. WaterUtilityReport.com presents official government records — we do not make health risk determinations, safety certifications, or compliance judgments. Consult a licensed water quality specialist or physician for health advice.
- —Records may be incomplete. EPA SDWIS and UCMR 5 represent what was reported to the EPA. Not all utilities or contaminants are covered. Small systems (<10,000 people) may not have been required to participate in UCMR 5 monitoring.
Independent Verification
Get your water tested by a certified lab
EPA compliance data shows what utilities report to regulators. An independent test from a certified laboratory confirms what is actually coming out of your tap at the point of use. Labs in New Jersey can test for PFAS (EPA Method 533 or 537.1), lead, nitrates, bacteria, and more.
