LT2 - Cryptosporidium
All public water systems using surface water or groundwater under the direct influence of surface water are required to monitor under LT2. Contact your state for sample scheduling. Below are monitoring frequencies and sampling start dates according to population:
|Population Served||Sampling Start Date (No Later Than)|
|>100,000||April 1, 2015|
|50,000 - 99,000||Oct. 1, 2015|
|10,000 - 49,000||Oct. 1, 2016|
|<10,000 (E. Coli)||Oct. 1, 2017|
|<10,000 (Crypto)||April 1, 2019|

Pathogens, such as Giardia and Cryptosporidium, are often found in surface water, and can cause gastrointestinal and other health risks. Cryptosporidium is particularly concerning in drinking water because it is resistant to chlorine and other disinfectants and has caused waterborne disease outbreaks. Consuming water with Cryptosporidium can cause gastrointestinal illness, which may be severe or fatal for sensitive populations (infants, the elderly or individuals with immunocompromised systems).
