A full-scale physical model of a modified infiltration trench was constructed to test a new storm water best management practice called an ecology ditch. The ditch was constructed using compost, sand, and gravel, and a perforated drain pipe. A series of 14 tests were conducted on the physical model. The tests controlled rainfall application and overland(More)

The primary objectives of this study were to quantify the affect of PCC slurry on roadside soil pH and to evaluate the effectiveness of using compost to at least partially neutralize slurry pH. Soil pH as a function of depth was determined along known areas of slurry disposal (I-90 and SR-195). Soil metal concentrations (cadmium, copper, lead and zinc) and(More)
This paper focuses on evaluating natural dispersion runoff infiltration performance by utilizing simulated rainfall/runoff data collected using a field-scale rainfall simulator coupled with a numerical model to study the effects of slope length, angle, and impervious contributory area on natural dispersion applications. A simplified equation was(More)
Chromium (VI) (Cr(VI)) contamination of soil and groundwater is considered a major environmental concern. Bioreduction of Cr(VI) to chromium (III) (Cr(III)) can be considered an effective technology in remediating Cr(VI) contaminated sites. Among the Cr(VI) reducing bacteria, Shewanella oneidensis MR-1 (MR-1) is relatively effective. Reduction of Cr(VI) by(More)
