Round 1 LT2ESWTR Cryptosporidium Monitoring Results
Cryptosporidium data from the first round of source water monitoring under the Long Term 2 Enhanced Surface Water Treatment Rule were analyzed and evaluated. This rule, promulgated in 2006, requires public water systems treating surface water or groundwater under the direct influence of surface water (GWUDI) to conduct two rounds of source water monitoring and on the basis of the results to implement treatment addressing public health risk from Cryptosporidium. This article summarizes data‐cleaning efforts, sampling and analytical results, binning outcomes, oocyst recovery, and relationships between Cryptosporidium and Escherichia coli measurements. The data indicate that 7% of large systems must implement additional treatment. Small system estimates are unreliable because the data represent only 3% of applicable systems. In aggregate, Cryptosporidium occurrence was higher in flowing stream–type surface water sources compared with reservoir/lake‐type surface water sources or GWUDI supplies.
