Sanitary Sewer Overflows: Untreated Sewage Releases in Bloomington

Sanitary Sewer Overflows (SSO) are releases of untreated sewage into the environment. The City of Bloomington Utilities Department records and maintains data for all SSO events within its wastewater system, with each event reported to the Indiana Department of Environmental Management. Columns suggest this dataset likely contains details on the location, volume, duration, and environmental context of each overflow event.

Use Cases

• Mapping spill locations and density using Lat/Long and Sewershed columns
• Analyzing overflow volume and environmental impact using Gallons and Drainage Basin columns
• Investigating the correlation between rainfall and overflow events using Rain and Start_Date columns
• Tracking the duration and response times of incidents using Start_Date and End_Date columns

Strengths

• Data is reported to a state regulatory body (Indiana Department of Environmental Management), suggesting a formal reporting process
• Dataset is maintained by a specific municipal department (City of Bloomington Utilities Department)
• Presence on multiple government data platforms (Socrata, Data.gov) indicates official status and potential for reuse

Limitations

• Key metadata like row count, file size, and author are missing or listed as 'unknown' across all sources
• Sources conflict on the 'last updated' date, with Socrata showing 2026-05-28 and Data.gov showing 2026-04-12
• The license is ambiguously listed as 'other-license-specified' without further detail
