Sanitary Sewer Overflows (SSO) are releases of untreated sewage into the environment. City of Bloomington Utilities Department records and maintains data for all SSO events that occur within Bloomington's wastewater collection and treatment system. Additionally, each event is reported to the Indiana Department of Environmental Management.

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.

Total organic carbon (TOC) is the total amount of organic matter in the water, and is used to evaluate water quality. TOC concentrations are regulated by the Safe Drinking Water Act through the Long-Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant Byproduct Rule. Both Rules identify removal requirements based on source water characteristics such as alkalinity and source water TOC levels. Generally, TOC is removed through the addition of coagulants during the flocculation and sedimentation processes and through the filtration process.

Dissolved organic carbon (DOC) measures the total amount of organic matter that can pass through a filter no larger than 0.45 µm. Since high levels of DOC may interfere with disinfection efficiency, DOC concentrations are monitored for removal before the disinfection stage of the water treatment process.

Both TOC and DOC are related to the formation of disinfection byproducts (DBPs). When leftover organic matter reacts with residual chlorine, DBPs may form (please see "Disinfection Byproducts (DBPs)" dataset for more information).

Taste and odor issues with drinking water stem from the presence of the organic compounds known as methylisoborneol (MIB) and geosmin. These two compounds are not harmful to human health. Rather, the presence of MIB and geosmin negatively affect the drinking water's aesthetics (geosmin causes an earthy smell, while MIB causes a musty taste). Taste and odor thresholds vary from person to person, but normally geosmin can be detected as low as 7-15 parts per trillion, while MIB can be detected as low as 20-30 parts per trillion.
