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.

Unmanned Aerial Vehicle (UAV) flight data for flights conducted by the City of Bloomington, Indiana. This dataset is updated bi-monthly. Last updated on July 24th, 2024.

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).

Data from the yard waste neighborhood program.

Electricity bills for the Monroe Water Treatment Plant. This facility receives two separate electricity bills, depicted by "1" and "2" in the data columns. This facility also has solar generation. Close to 100% of generation is consumed on-site, and is included in the total_kWh for site energy consumption.

Blucher Poole electricity usage (kWh), peak demand (kW), electricity cost, and influent volume (million gallons). Electricity at this facility is purchased from South Central Indiana REMC.

This data set contains data and maps related to the status of the Brighten B-town initiative.

The “Brighten B-town” initiative is a partnership among three City departments -- Parks and Recreation, Utilities, and Public Works -- representing a methodical, internally-coordinated and geographically-targeted delivery of upkeep and maintenance services designed for greater efficiency and more visible results. Spanning services the City regularly delivers over the course of the year -- including landscaping, painting, pruning and street cleaning -- the pilot program establishes an order for simultaneous delivery of those services to specified City zones, so that each zone will receive comprehensive attention within a discrete period.

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.

Data regarding the yearly operations of the Sanitation Division of Public Works. Sanitation is responsible for providing weekly collection and disposal of household solid waste and curbside recycling pick-up, as well as seasonal bi-weekly yard waste from residences inside the corporate City limits.

Sanitation also collects large items, such as furniture and appliances, from residences on a request basis. Additionally, Sanitation provides trash collection for City Hall, downtown containers, City parks, various City facilities and numerous special events in the community.

A couple of notes regarding these statistics:

The City of Bloomington Sanitation Modernization Program officially launched in October 2017. This program eliminated trash and yard waste stickers in favor of directly billing customers for their monthly trash cart rentals and yard waste pick-ups via their utility bills.

Also part of the modernized sanitation program, the City of Bloomington's recycling operations converted from co-mingled to single stream collection in 2017. This means that all recyclable materials (metal, cans, glass, fiber, paper, etc.) are now all collected together instead of separately.

Additionally, fiber and scrap rebates provided to the City of Bloomington by its recycling provider were effectively ended in 2017. This was largely due to major changes in international demand and fluctuations in the domestic commodities market.
