Protecting Northern California's Waters
Independent scientific water testing and environmental stewardship across our Northern California region's rivers and streams
Our Water Testing Mission
Water quality is fundamental to the health of our communities and ecosystems. We conduct testing of rivers and streams throughout Northern California to monitor contaminants, identify potential threats, and support informed environmental protection efforts.
Monitoring What Matters
Our testing program focuses on key water quality indicators including bacterial levels, chemical contaminants, and heavy metals.
Data-Driven Stewardship
Scientific data transforms good intentions into effective action. Our testing results inform regulatory compliance, support community science initiatives, and help identify problem areas that need intervention. This information is shared with environmental agencies, municipalities, and community organizations working to protect our waterways.
Geographic Scope
Our testing network spans Northern California's most important waterways, from the Sacramento region through the Bay Area and beyond. We strategically sample at locations that capture the diversity of our aquatic ecosystems—from mountain streams to valley rivers to urban waterways.
