The Stormwater Runoff Solution

Stormwater runoff is a concern for the environment
Stormwater runoff has become an increasing environmental concern as the urbanization of our society has created massive areas of impervious surfaces that flood our storm drains and waterways with pollutant-laden water. One effective solution in the control of stormwater runoff has been BIORETENTION, in which contaminants and sedimentation are removed from stormwater runoff. A key element to effective bioretention are soils used as filter media, commonly referred to as BIORETENTION SOIL or BIO SOIL.

Bioretention soils filter pollutants
Bioretention soils are designed to filter pollutants, provide effective infiltration, and support plant health. Typically, these soils are composed of sand, soil, and organic matter, with varying ratios depending on the intended use and specifications.
