VRAP establishes a regular volunteer-driven water sampling program to assist DES in evaluating water quality throughout the state. VRAP empowers volunteers with information about the health of New Hampshire’s rivers and streams. Regular collection of water quality data allows for early detection of water quality changes allowing DES to trace potential problems to their source. Data collected by VRAP volunteers are directly contributing to New Hampshire’s obligations under the Clean Water Act. Measurements taken by volunteers are used in assessing the water quality of New Hampshire’s river and streams, and are included in reporting to the US Environmental Protection Agency (EPA).
