We need your help! In 2014, the Environmental Performance Index created a first-of-kind indicator on national-level wastewater treatment. We devoted a ton of resources and staff time to sifting through a wide variety of data sources, but we know it was just a start. A new interactive map will crowdsource your feedback to help us refine and improve this important indicator of both ecosystem and human health. The video below explains how.
