City staff are dedicated to keeping our beaches safe for everyone to use, as a result we will be testing our swimming areas for bacteria this summer.
Testing Dates
Beginning June 1, 2010, the water at Crystal Lake Beach will be tested once a week for E. coli levels. If the level exceeds the standards set by the Minnesota Pollution Control Agency, the beach will be closed temporarily until the readings return to a safe level.
Interpreting the Results
Three samples are taken at Crystal Lake at different points along the beach (CL-N, CL-M, CL-S). The results are in units of Colony Forming Units (bacterial colonies) per 100 mL of water (CFU/100mL).
