An unsavory discovery was made on Wednesday near Pittsfield Elementary School in Ann Arbor where city officials located dried sewage and debris. According to CBS News Detroit, an estimated 75 gallons of raw sewage was spilled behind the school, at a sanitary sewer manhole, leading to concerns of environmental contamination.
The overflow, discovered in the grassy area behind the educational facility, was promptly addressed by the city's Public Works staff who utilized lime to mitigate any potential pollutants. As reported by ClickOnDetroit, this incident caused the sewage to flow towards a storm drain that connects to Swift Run creekshed, posing a possible threat to the local ecosystem, particularly the Huron River.
Despite quick actions to clean and neutralize the affected area, the cause of the overflow remains unclear. Officials have been conducting water testing to check for the presence of harmful bacteria such as E. coli, as mentioned by CBS News Detroit. The investigation into the overflow includes coordination between city representatives and the Washtenaw County Health Department. Michigan Department of Environment, Great Lakes and Energy have been notified, which is commensurate with regulatory requirements.
With Swift Run's confluence with the Huron River, city officials have issued recommendations for boaters to avoid the stretch downstream from South Pond as a precautionary measure until testing concludes. MLive shared, "Although Ann Arbor liveries are not impacted, city officials recommend boaters stay upstream of South Pond until around 5 p.m. on Friday, July 5." Future infrastructure improvements for the area surrounding Swift Run are slated to begin in 2025, aiming to preempt incidents of this nature and improve overall stormwater management.
