Extended Drinking Water Monitoring
In April 2024, the Navy began a voluntary 12 month extended drinking water monitoring program, which will collect 5,800 drinking water samples from homes that weren’t sampled in the previous Long Term Monitoring program (LTM). We will continue to collect drinking water samples at all schools, child development centers, Waiawa Shaft and hydrants throughout the distribution system monthly. Stage 5 data summary reports with an overview of what was found will be posted at the end of each quarter. Additionally, specific results from each location in this zone are posted monthly with their corresponding time period.
