While Loon Lake is constantly being tested for e-Coli throughout the summer months, there are many other tests that are being done on our water. Water clarity, phosphorus levels, invasive species tests as well as pH and alkalinity are monitored. Over the past few years, many lakes in Ontario have been under study for calcium levels by different groups, one of those groups being the Ministry of the Environment. Our lake being has been included in that testing. Here's a link to an article in this week's Haliburton County Echo that will give you more information including the importance of calcium in our water.

For 2009 and 2010, the calcium levels in Loon Lake have been at 17.8 mg/L and 15.1 mg/L respectively.
And it's my understanding that those levels should not be of any immediate concern.
In talking with the Ministry of the Environment, they hope to have an information paper or data sheet ready for publication in the Spring of 2011.
If you search the Internet, there is a wealth of information available on calcium depletion , one of them being at the following Queens University Link:

I'll keep you posted as more information becomes available.
