Get involved in your community while helping monitor and improve the local water quality!
Why Monitor Streams?
Clean, safe, usable water is essential to all life. Point sources and nonpoint sources of pollution—urban run-off that flows into storm drains from commercial practices as well as housekeeping practices—can negatively impact water quality downstream.
Protecting and ensuring the health of our streams and watersheds is everyone’s responsibility. It takes a collaborative network of dedicated and educated citizens all working together to understand and raise awareness about water issues, prevent water pollution, and improve water quality.
How do I become a water quality monitor?
The first step is to sign up for one of our Introductory workshops. Space is limited for these training classes, so register early!
