E. coli Test Results for Spring River at La Russell, 2011

The following are the results of weekly water quality testing by Jasper County Health Department at the La Russell Access point (referred to as Site SR1). Specifically, these are the number of Escherichia coli colonies per 100 milliliters of river water. The Environmental Protection Agency (EPA) had determined that swimming and body contact is NOT recommended when the sample exceeds 235 E. coli colonies per 100 ml. The Missouri Department of Natural Resources (MDNR) recommends a maximum of 126 E. coli colonies per 100 ml. as the limit for "recreational" swimming and whole body contact, annually between April 1 and October 31. The samples above the 235 threshold, are in bold.
