A water advisory has been issued at Caesar Creek Lake for an E. coli contamination.
The advisory was issued after samples were taken on Monday at 8 a.m. for Caesar Creek-South, according to the Ohio Health Department. The samples showed a result of 3840 cfu/100 ml, or colony forming units per 100 milliliters of water.
That value exceeds the Ohio Water Quality recommendations for public beaches of 235 colonies of E. coli per 100 milliliters of water.
The water quality is monitored throughout swim season for algae and bacteria from May through September. In 2016, Caesar Creek had two advisories — one that lasted a week and another that lasted only two days.
In the past five years, the longest contamination advisory was back in 2013, which lasted 27 days. That advisory was for high bacteria levels, and the pollution source was unknown.
