South Bend, Ind., Dec. 18, 2013 -UL (Underwriters Laboratories Inc.), a global leader in water quality and safety, announces today the certification of its drinking water analytical laboratory for second round testing in accordance with the Environmental Protection Agency's (EPA) Long Term 2 Enhanced Surface Water Treatment (LT2 Rule).
As a LT2 (Round 2) certified laboratory, UL is now accepting and scheduling sample testing for those Public Water Supplies required to comply with this rule. All public drinking water systems that use treated surface water or ground water that is under the influence of surface water are required to comply with this rule. According to the EPA's Long Term 2 Enhanced Surface Water Treatment: Quick Reference Guides, systems are required to monitor their source water, calculate an average Cryptosporidium concentration, and use those results to determine if their source is vulnerable to contamination and may require additional treatment.
"Our team is excited to help public water supplies across the country with the necessary compliance testing for Round 2 of the LT2 rule," said Nathan Trowbridge, Customer Experience Manager for UL's Drinking Water Quality Business. "From our Round 1 compliance experience, our team has the comprehensive understanding of the monitoring requirements outlined in the rule, allowing us to provide the highest level of customer service to our clients."
As in the first round of LT2 testing, the second round of LT2 monitoring continues the strong focus on monitoring Cryptosporidium to help reduce the potential health risks associated with such drinking water contaminants. Water systems with a population of 10,000 and greater will be required by the EPA to sample monthly for a total of two years, while water systems of less than 10,000 will be required to sample for E. coli bi-weekly for one year, with additional cryptosporidium testing after.
"Cryptosporidium is a concern for systems that use surface water. The negative impact on human health that Cryptosporidium can cause, due to its resistance to chlorine and other disinfectants, makes the concern even more significant," said Matt Hartz, Laboratory Operations Manager of UL's Drinking Water Analytical Laboratory. "UL understands the risks that Cryptosporidium poses, and as a global leader in safety, we are committed to helping public water supplies actively monitor these levels to help prevent any harm to the populations they serve."
