Frequent Questions

What elements does the Community Water System Survey (CWSS) take into consideration?

Conducted periodically by EPA, the CWSS contains information on community supplies, such as the types of treatment in place, water production and design flow, the number and types of water sources, and water distribution and storage configurations. This information, along with the water system financial data collected, serves as a baseline against which the effects of newly proposed regulations can be measured. Only community water systems are included in this.
