​

The result from this month's testing are quite low E. coli numbers due to us receiving very little rain this month.

​

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
