Selected latest compound samples from the published federal system record. Multiple sample points may share a date. A detection does not establish a violation. A non-detection does not mean PFAS-free. PFOA and PFOS limits and regulatory context are separate from these historical samples.

Lead and copper

Lead: 0.0031 mg/L, period ending 2023-12-01. These are system 90th-percentile results, not individual household concentrations.

Drinking-water compliance

No current violations flagged; past records available. 0 current flags and 10 historical records in the federal publication dated September 1, 2026. Historical records are not all active violations.

Drought around this place

This is the latest drought map in this publication, effective 2026-10-13; it is not a live report.

Miami-Dade County, Florida: 71.27% of county area in D1 or worse; 95.95% in D0 or worse. D0 means abnormally dry. On 2026-10-06, D1 or worse covered 71.27%.

County area shares at or above each severity: D2 28.75% · D3 0% · D4 0%. These cumulative percentages overlap and must not be added. County conditions do not describe every point in a city or a drinking-water restriction.

Groundwater

Limited data

Limited nearby monitoring

Few nearby wells have recent measurements available here. That limits what we can show; it does not mean groundwater conditions are poor.

Groundwater near Miami

Aquifers can supply water; monitoring wells measure water levels at individual sites. One well does not describe an entire aquifer or your household well.

Reading well data

What well measurements can tell you

A well’s water level does not tell us how much water an aquifer holds. Pumping totals alone do not show depletion, and a surface map does not show the aquifer’s full underground extent. To understand water quality in a private well, use tests from that well and local guidance.

UCMR5 PFAS monitoring

51 reported detections

Across 240 compound results and 12 samples for this water system.

Detection is not the same as violation.A reported detection is not, by itself, a drinking-water violation or a statement about a household tap. EPA states UCMR results do not indicate compliance or noncompliance with PFAS MCLs.
