Does Cheaspeake Bay Environmental Center have drinking water violations?
EPA's records list 7 violations for this system; 6 are health-based, and the most recent began in April 2020. The violations listed here began between July 2003 and April 2020. By type: 6 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them).
