Aquatechnex biologists will be treating Canyon Lake again today with Aluminum Sulfate to remove and sequester Phosphorus. This work will be performed from the Holiday Harbor ramp and applications will be primarily in that area and north. Tomorrow we will be focused on the north end of the main lake and Thursday the east arm.
We had a few questions about swimming near the applications yesterday. Aluminum Sulfate forms a precipitate with the phosphorus and settles rapidly. This products is used extensively in drinking water treatment plants that deliver potable water to your homes and is fully certified to be used in potable water systems without any restrictions on water use.
There are some pictures on our twitter and facebook pages that can be viewed from the links on the right.
