    Lake Killarney outlet dam (Cary, IL, 60013) by Eberhard Veit

    - Lake is frozen but outlet is free flowing - As Lake Chloride was so high in November, I tested several inflows to the lake, and they all tested higher than the lake, even before any snow fall and road salt. - Even my well water at the house tested higher than the lake. - If the ground water Cl- is above the lake that explains lake Cl- - In addition, all our septic systems and softener water goes to the lake - Data available upon request. - See attached picture of Veit well readings. - Even the inflow from the Hollows Conservation Area is higher. - See attached Hollows readings - As a Q/C check I tested a strip on Chloride free bottled water and it did read Zero.
