Iron-Enhanced Swale Ditch Checks for Phosphorus Removal
Swales and/or drainage ditches for linear road projects have excellent potential for stormwater treatment. They can infiltrate water into the soil, filter sediments and associated pollutants out of the water, and settle solids to the bottom of the swale. The research is measuring the performance of iron-enhanced ditch checks in roadside swales as a novel stormwater treatment system developed specifically for capturing phosphate and toxic metals from roadway runoff in both urban and agricultural environments. The result will be a water management innovation that will clean road runoff water quality.
