May, 2022 

​

Here are the results from our May monitorings. We had slightly higher E. coli levels than seen over this past year site averages, again, tracking with the recent rains and river rise. 

​

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

​

Per current Virginia Department of Environmental Quality (VDEQ) standards, there is no longer a safe E. coli level based on a single water sample but this is now based on a 90 day period of analysis. The bottom line is that 410 CFU is considered the upper limit of safety based on that 90 day analysis. The math is a bit complicated in making the final determination of safety but if you want more details feel free to shoot us an email and we'll explain the changes further.

​

Safe  – means the E. coli level is below the VDEQ Standard of 410 – water is safe for recreational use

Unsafe – means the E. coli level is above the VDEQ of 410 – water is unsafe for recreational use
