Labs can now electronically report drinking water compliance samples to TCEQ through the Compliance Monitoring Data Portal (CMDP) in an efficient and standardized format. This video shows you how to navigate the portal and enter microbial sample (coliform and E. coli) results. Beginning November 10, 2025, all accredited labs that analyze drinking water samples from public water systems are required to use CMDP. Find more information about CMDP at the Public Water System Supervision Program webpage tceq.texas.gov/drinkingwater/pwss.html
