"For more than a decade there has been concern about the large quantities of poor quality stormwater from urban watersheds and agricultural runoff reaching and contaminating surface waters including rivers and lakes. Municipalities, public agencies and industry have been encouraged to install stormwater treatment ponds and wetlands for improving water quality under the general planning of Best Management Practices (BMPs). This method of runoff treatment is promoted as a cost effective method to divert and treat poor quality water before it enters surface waters. Some of the BMPs include ponds and constructed wetlands to remove contaminants and suspended solids primarily through sedimentation, while also creating wildlife and fish habitat. There is concem about trace metals, excessive nutrients, agricultural pesticides, industrial by-products, roadside runoff, etc. settling in these constructed ponds and wetlands"--Abstract.
