Two disinfectant byproducts (DBPs), Total Trihalomethanes (TTHMs) and Haloacedic Acids (HAA5s) are regulated by the Safe Drinking Water Act through the Stage 2 Disinfectant Byproduct Rule. The City of Bloomington Utilities collects samples for DBPs monthly at 8 testing locations throughout the distribution system and follows a quarterly compliance schedule. Compliance is calculated on a Locational Running Annual Average (LRAA). The Maximum Contaminant Levels are 80 µg/l for TTHMs and 60 µg/l for HAA5s. Micrograms per liter (µg/l) is equal to parts per billion (ppb). One part per billion is roughly equal to a teaspoon of water in an Olympic-size swimming pool.

This dataset reports from after CSSE changed its daily report schema on March 22.
