Combined Uranium (pCi/L)
Uranium is a radioactive element commonly found in most rocks; processed ore is used for power generation and weapons manufacture.Testing Summary
| Contaminant | Average/ Maximum Result | Health Limit Exceeded | Legal Limit Exceeded | Testing History -Tested  -Detected  -Over Health Guidelines  -Over Legal Limit* |
|---|---|---|---|---|
| Combined Uranium (pCi/L)Uranium is a radioactive element commonly found in most rocks; processed ore is used for power generation and weapons manufacture. | 2.1 pCi/L 3.3 pCi/L | No | No 15 pCi/L |  |
| NOTE: Each dot in the above graph represents one month. * Water utilities are noted as exceeding the legal limit if any test is above the maximum contaminant level (MCL). Most MCLs are based on annual averages so exceeding the MCL for one test does not necessarily indicate that the system is out of compliance. | ||||
Health Based and Legal Limits for Combined Uranium (pCi/L)
Health Based Limits for Combined Uranium (pCi/L)
| Standard | Description | Level |
|---|---|---|
| Maximum Contaminant Limit (MCL) | The enforceable standard which defines the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to health-based limits (Maximum Contaminant Level Goals, or MCLGs) as feasible using the best available analytical and treatment technologies and taking cost into consideration.
