PUBLIC NOTICES

Definitions

RAA — Running Annual Average.

Maximum Residual Disinfectant Level (MRDL) — 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.

Maximum Residual Level Goal (MRDLG) — The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLG’s do not reflect the benefits of the use of disinfectants to control microbial contaminants.

AL (action level) — The concentration of a contaminant which, if exceed, triggers treatment or other requirements which a water system must follow.

MCL — Maximum Contaminant Level (MCL) is the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLG as feasible using the best available treatment technology.

MCLG — Maximum Contaminant Level Goal (MCLG) is 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.

NTU — Nephelometric Turbidity Units ppb — Parts per billion ppm — Parts per million ppt — Parts per trillion

TT — Treatment Technique (TT) is a required process intended to reduce the level of a contaminant in drinking water.

Unregulated Contaminants — Unregulated contaminants are those for which EPA has not established drinking water standards. The purpose of the unregulated contaminant monitoring is to assist

Per- and polyfluoroalkyl substances (PFAS) - Sampled at Water Filtration Plant

Note 1: Definitions are on page 6. Note 2: The EPA requires monitoring over 80 drinking water contaminants. Those listed above are only those contaminants detected in your drinking water. For a complete list contact the Water Filtration Plant.

EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted.

90th Percentile — 90 percent of the samples were at or below the numbers listed. (Copper = 100 ppb, Lead = 3 ppb).

N/A — Not applicable.

*- Turbidity — Turbidity is a measure of the cloudiness of water. We monitor it because it is a good indicator of the effectiveness of our filtration system.

100 percent of our samples met the required limits of less than or equal to 0.30 NTU in 95% of samples taken each month and shall not exceed 1.0 NTU at any time.

**- Lead & Copper — The state allows us to monitor for some contaminates less than once per year because the concentrations of these contaminants do not change frequently. Some of our data, though representative, may be more than one year old. Copper and lead samples were collected on 8-07-21 through 8-25-21.

Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure. Our water supply has zero lead service lines and zero service lines of unknown material out of a total of 1700 service lines.This concludes our report for the calendar year 2022. Your 2023 Water Quality Report can be expected before July 1, 2024.
