Procedures 2011

Please Note: Click Here To View The River Health Index Data With the new calendar year (2011) SLCR decided to modify its testing methods by obtaining results for E-coli vs. fecal-coli form. Fecal-coli form is a more general measurement than E-coli measurements. E-coli is now a more recommended measurement, (currently being used by the State of Missouri and Illinois) and as such SLCR has decided that even though there is an added cost the test will provide a more meaningful reference point. At this time the EPA data published in 1997 indicates that a reading in excess of 100 E. coli per 100 ml would likely cause on average of 8 illnesses per 1000 swimmers. Illnesses are similar to those seen in a treated pool where operation and maintenance is less than required. Full body contact increases the risk of illness. The amount of full body immersion (FBI) varies over the areas where the tests were taken. SLCR is not determining that FBI will occur, however when boating or waterskiing occurs one will surely be exposed to that potential. The charts and graphs below are an indicator of what the St. Louis Confluence Riverkeeper has identified (with the help of a certified testing lab) on the indicated dates. This testing is expensive and any assistance in providing for these expenses will be beneficial. SLCR is, at the beginning of 2011, using PDC Laboratories, Inc, 3278 N. Highway 67, Florissant MO 63033 as its testing facility. They are NELAC certified. The test site locations are the same as those used at year end of 2010, see the test data section of the website for exact location details. It is SLCRs goal to take all of the test site readings as close together as possible. All locations are done both from shore and by boat as conditions allow. Boating safety is a primary concern and depending upon the river conditions, the spread between the two test dates may vary. The chart below indicates the actual dates that a month's tests were taken. SLCR has also indicated as a reference on the chart the EPA limit of 100, as the safe limit for Full Body Immersion. SLCR is also indicating any major issues observed which might indicate a difference in test results.
