Pollution Trade-Off to Clean Up
Phosphorus is a nutrient common in human and animal waste, and farm fertilizer runoff. It feeds algae growth in rivers that can be more than an eye-sore; it can choke off fish and other aquatic life. The Boise River’s cleanup plan developed over the past 20 years – has required phosphorus levels from all sources to come down to meet water quality standards.
The Environmental Protection Agency (EPA) issued a draft permit to the city of Boise for a small wastewater facility to remove phosphorous at a drain that carries runoff from thousands of acres of farmland more than 25 miles downriver from Boise. This is pollution trade-off and it could potentially be a model for cleaning up other rivers cheaply and efficiently.
