EPA rule code 0800 · Treatment Technique

What it means: The LT2 ESWTR (2006) required all surface water and GWUDI systems to monitor source water for Cryptosporidium, then apply additional treatment based on measured concentrations. Higher-bin systems (more oocysts detected) must install advanced treatment — UV disinfection, ozone, or membrane filtration — beyond the original SWTR requirements.

Health effects: Cryptosporidium is a chlorine-resistant protozoan parasite that causes cryptosporidiosis — severe watery diarrhea, cramping, nausea, and fever. In immunocompromised individuals (HIV/AIDS, transplant recipients), it can be life-threatening and prolonged. Infants and the elderly are also at elevated risk. LT2 violations indicate failure to complete monitoring or apply the required additional treatment tier.

Limit: Treatment technique — additional Cryptosporidium treatment based on bin classification

About this rule
About this data

EPA counts the rules a system was in violation of, not the individual violations; one rule can carry several in the same period. Unresolved means still in violation at EPA's latest data refresh. Measured contaminant levels are not part of this record; each system publishes them in its annual Consumer Confidence Report.

The North Carolina records are from EPA's data refresh of Oct 7, 2026; EPA refreshes this data quarterly, and states report to EPA with a lag of three to six months, so the newest violations may not appear yet.
