septic system

There are roughly 48,000 on-site septic systems in Washtenaw County, according to the Washtenaw County Environmental Health Division.  State statistics show that at any given time 10% of those systems are leaking and in need of repair.  In this week’s "Issues of the Environment," WEMU’s David Fair talks with Michigan Department of Environmental Quality’s David Cotton about the growing number of these systems and how to protect our land and waterways.
