Beach Monitoring Program
The Oakland County Health Division Beach Monitoring Program for 2009 will begin on June 1st and run until July 31st. This year the County will be monitoring 30 public and semi-public beaches on 25 different lakes.
The water collection and beach surveying are done by environmental health students hired by the County for summer internships. Water at each of the beaches is tested on a weekly basis, measuring for an indicator bacteria, E. Coli. As an indicator, if E. Coli is present, other, more harmful and harder to detect organisms could be present.
Monitored beaches are to meet the one day standard of 300 colonies per 100 milliliters of water AND the 30 day geometric average standard of 130 colonies per 100 milliliters. If a beach does not meet the water quality standard, it will be closed until satisfactory samples are obtained. A listing of closed beaches can be obtained at:
