U.S. EPA SDWIS lead and copper monitoring records
These are 90th-percentile monitoring summaries for the stated reporting periods. Individual sample dates are not supplied. A reported zero is retained as published; it does not establish that lead or copper is absent at an individual faucet.

| Lead (90th percentile)Lead and Copper Rule monitoring · 90th percentileSource stream: monitoring-period/2022-01-01/2024-12-31 | 2022-01-01 to 2024-12-31 (reporting period) | 0.001System-level 90th percentile of tap samples for the stated monitoring period. The period boundaries are reporting windows, not individual sample dates. A missing result-sign code is retained as unspecified; a zero is not relabeled as a non-detection. Individual household lead or copper concentrations can differ. | mg/L | Not supplied | A monitoring-period 90th percentile is not a compliance determination or a measurement of an individual household's water. |

Utah IBIS yearly mean drinking-water concentrations
These are annual monitoring averages, not individual sample results or compliance determinations. A reported zero does not establish that every sample was below detection. Sampling years are shown separately from the date this site retrieved the data.
Historical annual means from Utah public monitoring records. Latest published years vary by contaminant and provider; seasonal and emergency sources are excluded. Sampling frequency and within-system variability differ. These averages cannot establish an individual tap result, detection status, or current compliance.

A detection is not automatically a violation. Household plumbing can also affect water measured at an individual tap.
