E. coli Monitoring Results
July, 2021
This is the first sampling at our 8 new monitoring sites on lower Middle River. All sites are located between the Route 250 bridge at river mile 46.2 and the Craig Shop Road bridge at river mile 5.5. All the E. coli counts were in a healthy range and this is great news! The water levels are low and there has been little rain to cause significant runoff into the river. It will be interesting to see if there are changes when we get any rain.
E. coli results are based on the number of E. coli Colony Forming Units or CFU per 100 milliliters of water (approximately 3.4 ounces) – CFU/100ml
If the number of CFU/100ml is over 235, the water is not safe for recreational use.
Good – means the E. coli level is below the Environmental Protection Agency Standard of 235 – water is safe for recreational use
High – means the E. coli level is above the Environmental Protection Agency Standard of 235 – water is unsafe for recreational use
