1 open treatment violation.

Open for: Lead and Copper Rule. EPA counts treatment-technique violations as health-based: a required protective step was not done. It is not a measurement of contamination.

On record since 2013: 32 violations. 1 over the limit · 6 treatment lapses · 17 missed or late tests · 8 notices or reports. Most recent began 2023-03-24.

For this year's test results, ask the utility for its annual Consumer Confidence Report. Every community system must publish one.

More violations on record than 92% of active water systems in Wyoming. Small systems with no staff chemist often rack up missed-test violations; big utilities rarely do.

The record, year by year

One square = one violation, by the year it began. Empty columns are years with nothing on EPA's record.

3% over the limit · 119% treatment lapse · 653% missed or late test · 1725% notice or report · 8

Across Wyoming, 85% of violations are missed or late tests and 4% are water over a limit.

What you can do

Lead: Run cold water for 30 seconds to 2 minutes before using it for drinking or cooking, especially after the water has been sitting for several hours. Use only cold water for cooking and baby formula. Consider a water filter certified to remove lead (look for NSF/ANSI Standard 53 certification). Have your water tested if you live in an older home.

Lead & copper at the tap

Utilities sample taps in homes most likely to have lead pipes, and report the 90th-percentile result: 9 in 10 homes sampled came in at or below this number. Above the red line (the action level) the utility must act. The action level is not a safe level; EPA's health goal for lead is zero. EPA's file does not date these results, so they are shown highest first.

Reading this record

Rivermeadows Water District is a community water system that draws from groundwater and serves about 100 people in Jackson, Wyoming. Everything above comes from the EPA's Safe Drinking Water Information System (SDWIS), where states report every violation by every public water system.

Four kinds of violation. Only one is a measurement of the water: over the limit means a test came back above a legal maximum (an MCL). A treatment lapse means a required protective step was not done, such as disinfection, filtration, fixing a defect an inspector found, or filing a lead-pipe inventory. A missed or late test means a required test was skipped or never reported. That is the most common kind, and the most misread: it does not mean the water was bad, and it does not mean the water was fine. Notices and reports covers public notices and the annual Consumer Confidence Report.

Status. “Back in compliance” means the state recorded a return to compliance. “Period ended” means the violation's compliance period is over but no return to compliance was ever filed, which is common in older records. EPA's federal copy lags state records by months, so call the utility for anything current.
