Stormwater pollution control using Black and Gold media

Abstract

A widely used roadway runoff best management practice (BMP) used in Florida is an ex.filtration trench. Traditionally, exfiltration trenches are constructed without any filtration media. Therefore, the potential for groundwater contamination by the roadway runoff exists. Roadway runoff contains metals and nutrient pollutants. Nitrogen and Phosphorus are the most common nutrients causing impacts to receiving waters. To reduce the impact these pollutants will have on groundwater quality, Black and Gold™ media, which mainly consists of tire crumb, is evaluated.

The Black and Gold™ media was found to be a good filtration media for removal of total nitrogen and nitrate + nitrite. It was found that all of the wells had experienced total nitrogen removal. These reductions ranged from 32% to 56%. The nitrate + nitrite reduction was experienced in the four wells. These reductions ranged from 4 7% to 88% in the three wells. The ortho-phosphorous and total phosphorus concentrations did not change significantly. Also, the metals concentrations did not change significantly.During the post sampling period, the turbidity of the groundwater increased. This was experienced in three of the four wells.
