1. IntroductionThere are a host of very serious concerns related to too much phosphorus in our water: risks to human safety from the threat of harmful algae blooms near drinking water intakes; unstable fish communities due to harmful algae blooms and low levels of dissolved oxygen; declines in property values due to loss of recreational opportunities and aesthetics; disruptions in food web and energy flow that cause negative impacts on species and their habitat; degraded habitats especially in nearshore, wetlands and tributaries due to increases in algae growth; beach fouling and loss of tourism revenue; and added costs to municipalities, industry and the public to protect drinking water sources, and restore recreational areas.
Examples of phosphorus containing materials include; fertilizer, manure, and human waste. There are also naturally occurring sources of phosphorus in lakes, such as decaying organic matter, and eroding rocks and soils.
