Testing History

-Tested      -Detected      -Over Health Guidelines      -Over Legal Limit*
Uranium-234 (pCi/L)0.12 pCi/L
3.33 pCi/L
NoLegal at any levelThis is the Federal Limit. State Limits may be lower.
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.
