Tap water samples were collected for lead and copper analyses from sample sites throughout the community.
| Substance (Unit of Measure) | Year Sampled | AL | MCLG | Amount Detected (90th %ile) | Range Low-High | Sites Above AL / Total Sites | Violation | Typical Source |
|---|---|---|---|---|---|---|---|---|
| Copper (ppm) | 2025 | 1.3 | 1.3 | 0.23 | 0.002–0.36 | 0/30 | No | Corrosion of household plumbing systems; Erosion of natural deposits |
| Lead3 (ppb) | 2025 | 15 | 0 | 1.3 | ND–4.4 | 0/30 | No | Corrosion of household plumbing systems; Erosion of natural deposits |
1The value reported under Amount Detected for TOC is the lowest ratio of percentage of TOC actually removed to the percentage of TOC required to be removed. A value of greater than 1 indicates that the water system is in compliance with TOC removal requirements.
2Turbidity is a measure of the cloudiness of the water. It is monitored because it is a good indicator of the effectiveness of the filtration system.

Definitions
90th percentile: The levels reported for lead and copper represent the 90th percentile of the total number of sites tested. The 90th percentile is equal to or greater than 90% of our lead and copper detections.
AL (Action Level): The concentration of a contaminant that, if exceeded, triggers treatment or other requirements that a water system must follow.
MCL (Maximum Contaminant Level): The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
MCLG (Maximum Contaminant Level Goal): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
MRDL (Maximum Residual Disinfectant Level): The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
MRDLG (Maximum Residual Disinfectant Level Goal): The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.
NA: Not applicable
NTU (Nephelometric Turbidity Units): Measurement of the clarity, or turbidity, of water. Turbidity in excess of 5 NTU is just noticeable to the average person.
ppb (parts per billion): One part substance per billion parts water (or micrograms per liter).
ppm (parts per million): One part substance per million parts water (or milligrams per liter).
TT (Treatment Technique): A required process intended to reduce the level of a contaminant in drinking water.
