NRWA Water Monitoring Program

This year (2018) marks the twenty-sixth season that dedicated volunteers have monitored water quality and reported conditions and observations at over 44 sites throughout the Nashua River watershed. The Water Monitoring Program builds community awareness of water issues, helps identify and restore problem sites, promotes advocacy for our watershed, and increases the volume of information available on our waters. We use the monitoring results to create a River Report Card that is shared with volunteers, the public, and Massachusetts and New Hampshire state agencies each month. View historic water quality data. For more information on what we monitor, and why, see our Volunteer Water Monitoring Manual. Monitoring for the 2018 season is supported in part by grants from Suez Water, Fieldstone Foundation, and Nashua West Rotary.

For a peek at what it's like to be a volunteer monitor, view videos created by Dawn McCall and Mike Labbe, NRWA Water Monitors from Shirley: Water Sampling and In the Lab.
