Learn About Our Impact

Expanding Access to Water Quality Monitoring

Globally, more than 3 billion people lack water quality data. Expanding access to monitoring tools helps communities protect their water and safeguard public health.

High school science teachers install an EnviroDIY Monitoring Station near a stream in Lancaster County, Pennsylvania.

Bhutanese women identify aquatic macroinvertebrates.
