Bioretention has been the principal form of Low-Impact Development (LID) used to slow, treat, retain and infiltrate stormwater runoff, mimicking a site's natural, pre-development hydrology. One aspect of bioretention that has some scientists and regulators concerned is the phenomenon known as nutrient leaching. Nutrient leaching occurs when the bioretention media, which often contains compost, breaks down and releases phosphorus to downstream receiving waters.
