Ortonville- For the second time this year, elevated E. coli levels in the Kearsley Creek have local officials concerned for the safety of residents and seeking answers regarding the source of the contamination.
According to a bacteriological analysis of the Kearsley Creek, performed by the Oakland County Health Division, on Sept. 15 near the Mill Street bridge, E. coli levels of 1,553 and 1,300 CFU (Colony Forming Units) were reported. Both test results were obtained by The Citizen through the Freedom of Information Act, were rated unsatisfactory by health officials.
Phil Sanzica, chief engineer for the Oakland County Drain Commission says while the E. coli levels exceed the state standards for both full and partial body contact, it’s very typical for urban areas of Oakland County.
‘We’re concerned there could be failing septic systems but we’re not alarmed,? said Sanzica. ‘This is a good indicator there are needs to be addressed in the area. It’s very typical of urban flow, or a number of issues along the creek.?
In May, a similar test for E. Coli levels in the Kearsley Creek was performed, resulting in a 780 CFU, and again in June, a report of 618 CFU. All tests exceeded the 300 CFU limit considered safe for full body contact with the water.
Following the May and June E. Coli reports, Ron Fadoir, Oakland County Drain Office environmental planner, recommended a more accurate sample of the creek water over longer periods of time be considered. The flowing water in the Kearsley Creek also influences the accuracy of the sample, since the creek continually flushes debris through the area, Fadoir said.
Concerned for the health of the community, a representative from the Oakland County Drain Office and the Oakland County Health office attended the June 10 CreekFest where water contact could be possible. As a result of these tests, village officials posted a public notice of unsafe E. coli levels near Kearsley Creek access areas on village property.
Ortonville Village Manager Ed Coy says the E. coli reports have prompted a further investigation of the creek and tracing the source of the contamination is forthcoming.
‘The recent duck race as part of Septemberfest prompted the water tests to assure safety of those around the creek,? said Coy. ‘The Oakland County Drain Commission contacted us and since the situation is progressively worse they suggested we attempt to identify the source of the contamination. We’re taking them up on the offer.?
Sanzica emphasizes that the local community should be active in the management and planning of the creek, such as committees and groups in Oakland County working on such environmental issues regarding the watershed of the Clinton River.
