EPA Launches Portal for Drinking Water Compliance Monitoring

The U.S. Environmental Protection Agency (EPA) has launched a new Compliance Monitoring Data Portal (CMDP), allowing electronic reporting of drinking water compliance data from laboratories and drinking water utilities straight to primacy agencies.


Intended to modernize and streamline the reporting process, the CMDP is expected to increase the accuracy, efficiency and usability of the vast quantities of drinking water data submitted to primacy agencies. For the longer term, the CMDP one of the first tangible pieces that will feed into EPA’s overhaul of the Safe Drinking Water Information System (SDWIS).

The Compliance Monitoring Data Portal (CMDP) will enable drinking water utilities and laboratories to report data electronically to primacy agencies with fewer errors and in a more efficient manner. The portal will increase data accuracy and completeness and once fully implemented, can potentially decrease the overall reporting burden for primacy agencies hundreds of thousands of hours.

Primacy agencies can use the portal-reported data to make more informed decisions about water system compliance and focus their limited resources on preventing and responding to public health problems. The portal does not require new reporting. Primacy agencies, water systems, and laboratories will continue to report data to EPA based on the content and schedule outlined in the current regulations.

EPA is also actively developing a modernized Safe Drinking Water Information System (SDWIS) called SDWIS Prime that will improve state decision-making by using the data received from the portal to develop new reports and provide automated notifications. The SDWIS Prime is currently projected to be completed in 2018.
