The Commonwealth Utilities Corporation in Saipan has incurred several drinking water violations for coliform bacteria.
According to CUC's latest water quality report, the utility agency had violations in the drinking water maximum contaminant level for total coliform in seven months.
The Environmental Protection Agency or EPA says the presence of fecal coliform or E. coli in drinking water is a serious health concern.
Federal law requires the CUC to tell the public about any drinking water violations.
According to CUCs' report, fecal coliform or E. coli are generally not harmful themselves, but their presence in drinking water is serious because they are usually associated with sewage and animal waste.
The contaminated water may cause disease, with symptoms that may include diarrhea, cramps, nausea, and any associated headaches and fatigue.
The report says CUC did repair pipeline leaks and, when needed, added extra chlorine to the reservoirs and pumping stations.
