Score Drivers

MISI score is 21.000 (Watch).
Compliance Escalation adds 6.000000 points. Operational compliance contributes +6: 10 violations or enforcement actions have been recorded within the last three years.
PFAS Contamination Risk adds 6 points. PFAS contamination contributes +6: detections=4, max result=9.030000 ng/L.
Lead & Copper Rule Risk adds 5 points. Lead and copper risk contributes +5: lead sample exceedances=0, copper sample exceedances=0, legacy action-level exceedances=0, open LCR violations=0.
Current Drought Severity adds 4 points. Current drought severity contributes +4: USDM severity index is 0.5260 as of 2026-04-14.
Missing or unresolved factors: Infrastructure Capital Gap, Parent-Government Fiscal Stress.

MARKET INTERPRETATION

What the data suggests

Williamston is a smaller community water system, serving approximately 7,650 residents. At the latest reading, Munimetric flags the system as showing early but meaningful signs of structural stress.

The score is being driven mainly by Capex Pressure, with Operational Stress adding further pressure. The pressure is distributed rather than concentrated in a single dimension.

4 active stress signals are attached to this system, including one at high severity. The breadth of active signals, even without concentrated high severity, suggests pressure across more than one dimension.

Within its peer cohort, this system ranks around the 30th percentile on measured stress, placing it below typical peer-group stress levels.

Recent score history has been relatively steady, consistent with the system's overall profile.

This summary is based on structured, source-backed public data and is intended for research and monitoring only. It is not investment advice, a credit opinion, or municipal advisory guidance.
