Lead and copper summaries

Each row is one summary of one monitoring period, and the agency records more than one kind.

61–80 of 612 monitoring-period summaries. From monitoring periods beginning September 25, 2024 to September 25, 2026. These dates are applied here by default; they are not a limit on what the agency records. Show 5 years, back to September 25, 2021.

This page can show a range of up to 5 years at a time. That is a limit of this service, not of what the agency records.

How to read a summary

Each row summarises one analyte over one monitoring period for one system. The number of samples behind each value is in the column beside it.

The agency records more than one kind of summary, and the Type column says which. Type 90 is the ninetieth percentile — the value 90% of that period’s samples fall at or below. The agency publishes no explanation for the other codes, so this page does not offer one: a value of another type is not a 90th percentile and must not be read as one.

Lead and copper sample summaries across the systems Mississippi State Department of Health serves, 61 to 80 of 612 monitoring-period summaries shown. Each row is one analyte over one monitoring period for one system, and the Type column says which kind of summary it is — only type 90 is a ninetieth percentile. The rows are in the agency’s own order and are not ranked by value.
