    Lake Killarney to Silver Lake Creek (Cary, IL, 60013) by Eberhard Veit

    Ran Q/C test on strip Lot# A4290A - See pictures. One strip read 209 PPM the other 226. Not sure what the acceptable range is. - This was just before the first snow of the season. - Only little snow fell on warm ground and only very little salt was used in addition to snow plowing. - Air and water temperature are no problem to get. I bought an inexpensive Thermometer all plastic at Ace Hardware for about $5.- It agreed with my digital thermometers. - - - This Creek is the outflow of Lake Killarney: *** Chloride seems very high for the time of year. My suspicion is that it is caused by water softeners and septic systems in the Lake Killarney subdivision. Our water has a lot of Iron and many people have water softeners. All houses on the West Side of the Lake have well & septic. Houses on the East Side of the Lake have community water & septic
