Phosphates and what they mean to you!

This is a simple layman’s explanation of phosphates as they relate to water quality

Phosphates enter the water system in many ways, some natural, and some directly related to human activities.

Shoreline land use and human impact are usually the dominant cause of increasing level of phosphorous in our water

Phosphates are a good thing at the right levels.  When the levels get too high – water quality deteriorates.

The Sturgeon Bay area, just west of Point au Baril, is an example of how things can go wrong, and is a great example of why your stewardship Council is doing their work now ands is concerned that we don’t become another Sturgeon Bay.

For more information about the issues at Sturgeon Bay, go to  www.oursturgeonbay.com

Phosphorous is measured in `parts per billion (ppb).

Generally, a concentration of 5 to 10 ppb is considered healthy for a fresh water environment.

Readings in the 10 to 15 ppb range are a signal for concern

Readings above 15 ppb indicate there are water quality problems

As we get the results of our 2008 testing, we should be able to identify specific areas where we work to improve water quality

In 2009, we plan a more comprehensive education and information program to work with any area where we see phosphate levels that are too high.  This proactive management is the best way to make sure we avoid major problems in the future
