NH DES Water Testing

Information on Drinking Water Testing

NH Department of Environmental Services issued recommendations for voluntary testing of lead in drinking water at all schools and daycares in the spring of 2016, following increased awareness of lead toxicity to children from the water crisis in Flint, Michigan. The Londonderry School District contracted with a certified company to perform the testing in all of our schools. A total of 134 fixtures were tested according to DES protocols. All but 3 samples came back with satisfactory results. The 3 fixtures were flushed and re-tested, and the results were well below action standards.

On February 8, 2018, Governor Sununu signed Senate Bill 247 Prevention of Childhood Lead Poisoning. This law requires, among other actions, that all schools and licensed childcare facilities test lead in drinking water at all locations where water is available for consumption by children. The first round of testing is required to be completed by July 1, 2019, and every 5 years thereafter, until at least 3 rounds are below the standard. Such testing completed from 2016 forward is acceptable for the first round of sampling.

Listed below are the results of the sampling that was completed in 2016. In accordance with SB 247, the School District will perform the second round of water testing in 2021.
