Information about Lead and Copper Sampling and Results
This is a Community Water System and serves approximately 3,283 people year round.
This system is required to collect 1 sample from 20 sites when performing "standard monitoring;" and 1 sample from 10 sites when performing "reduced monitoring."
All water systems were initially required to collect samples during two consecutive six month monitoring periods. If the results from those samples were below the Action Level* then the system may reduce the number of samples collected and reduce the frequency to once per year. A water system that has results below the Action Level three years in a row, may further reduce the frequency to once every three years.
This system is currently on REDUCED MONITORING and collects 10 samples ONCE EVERY 3 YEARS.
The system reports the 90th percentile result (90% of the samples collected are not over this value). The most recent results for this system are:
The Action Level (AL) for Lead = 15 ug/l; the Action Level (AL) for Copper = 1300 ug/l
ug/l means microgram per liter

Sampling Results for Other Contaminants
All Community Water Systems are required to produce a document each year (by July 1) that lists the most current results (from the previous year) of all contaminants detected in their water. This document is known as a Consumer Confidence Report. To see the latest Consumer Confidence Report for this water system click here.
