Notes

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.
*** Chloride seems very high for the time of year.
My suspicion is that it is caused by water softeners and septic systems.
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
