Cryptosporidium parasites get into surface water sources, such as rivers and lakes, from the stool feces of infected animals or people. Public water systems that get their water from these surface water sources can contain Cryptosporidium oocysts the egg-like form of the parasite. Filtration treatment will usually remove Cryptosporidium oocysts.
Chlorine disinfection by itself is not effective. All Virginia public water systems that use surface water sources provide filtration treatment. LT2 requires that all water systems that obtain their water from surface water sources must monitor the raw source water for Cryptosporidium oocysts or indicator organisms. Monitoring results will indicate whether systems will be required to provide additional treatment to achieve effective Cryptosporidium reduction.
