Regulated Contaminants
In the tables below, we have shown the regulated contaminants that were detected. Chemical Sampling of our drinking water may not be required on an annual basis; therefore, information provided in this table refers back to the latest year of chemical sampling results.
| Microbiological | Result | MCL | MCLG | Typical Source |
|---|---|---|---|---|
| COLIFORM (TCR) | In the month of July, 1 sample(s) returned as positive | Treatment Technique Trigger | 0 | Naturally present in the environment |
| Unregulated Contaminant Monitoring Rule (UCMR) | Collection Date of HV | Highest Value (HV) | Range of Sampled Result(s) | Unit |
|---|---|---|---|---|
| Lead and Copper | Period | 90TH Percentile: 90% of your water utility levels were less than |
