Pond Water Quality

The water in the pond is tested over the course of the swimming season, for both E.Coli and phosphate. The water quality has been good and the sample is always “found to be within acceptable levels for swimming & fishing.”

Max EPA recommended level for E.Coli is 235 (drinking water should be under 1), no recommendation for phosphate.
