Disinfectants Disinfection Products | MCLG | MCL | Highest Level Detected | Violation |
Likely Source of Contamination |
Chlorine (ppm) (2024) | 4 | 4 | 0 Range: 0.07-0.45 | No | Water Additive used to control microbes |
Haloacetic Acids (HAA5) (2024) | No goal for the total | 60 | 5.0 Range 5.0-6.0 | N | By-product of drinking water disinfection |
Total Trihalomethanes (TTHM) (2024) | No goal for the total | 80 | 8.0 Range 7.0-7.6 | N | By-product of drinking water disinfection |
Inorganic Contaminants | MCLG | MCL | Highest Level Detected | Violation | Likely Source of Contamination |
Sodium (2024) (ppm) | N/A | N/A | 160 | No | Occurs Naturally |
Unregulated contaminant |
|
| Range 140-160 |

Fluoride (2024) (ppm) | 4 | 4 | 1.6 Range 0.96-1.6 | No | Erosion of natural deposits; Water additive which promotes strong teeth, Discharge from fertilizer and aluminum factories. |
Nitrate (ppm)(measured as Nitrogen) (2024) | 10 | 10 | 0.046 Range 0-0.046 | No | Runoff from fertilizer use; Leaching from septic tanks, sewage; Erosion of natural deposits. |
Radioactive Contaminants | MCLG | MCL | Highest Level Detected | Violation | Likely Source of Contamination |
Beta/photon emitters (2019) (pCi/L) | 0 | 50* | 4.06 pCi/L Range 0-4.06 | No | Decay of natural man-made deposits |
*The MCL for beta particles is 4 mrem/year. EPA considers 50 pCi/L to be the level of concern for beta particles. Because the beta particle results were below 50 pCi/L, no testing for individual beta particle constituents was required. | |||||
