Survey of Storm Water Quality in an Urban Environment
A variety of contaminants are found in urban storm water runoff. Research was carried out on several catch basins around Youngstown State University in Youngstown, Ohio with the purpose of identifying areas of high contaminant concentration for future studies. The area has a variety of land uses, …

Evaluation of water distribution system monitoring using a combined simulation-optimization approach
… was used as the basis for a case study of contaminant transport under conditions of uncertainty. The model was not calibrated due to the lack of reliable field data. Optimization of monitoring plans was performed within the context event based simulation trials. This precluded the design of …

PAH and PCB distribution in sediment fractions and sorptive phases
Contaminant distribution is integral to environmental evaluations of contaminated sediment on every level. The technical and economic feasibility of treatment or beneficial use is a function of the accessibility or separability of the contaminants within the sediment. The magnitude of release to …

Finite element modeling of contaminant transport through confined disposal facilities
… pore water of the dredge soils. However, these contaminants frequently seep back into the water from which the dredge was removed. The primary objective of this research was to modify the existing finite element program POLUT2D to evaluate the rate and quantity of contaminant transport through …

Wastewater treatment by novel hybrid biological – ion exchange processes
… methods for treating important environmental contaminants from two different wastewater streams. One process utilizes the kinetic advantages and reliability of ion exchanging clinoptilolite in combination with biological treatment to remove ammonium from municipal sewage. A second process, …

Characterization and Removal Efficiency Comparison of Bioretention Soil Media Mixtures
… technique to help infiltrate and remove contaminants from stormwater runoff. Bioretention cells are constructed from a layered or heterogeneous soil mixture designed to optimize their ability to infiltrate influent stormwater and remove contaminants carried by the water as it filters …

Evaluating the relative importance of stormwater for nutrient and metal contamination to the urban, groundwater dependent Yellagonga Wetlands, through wetland budgeting
… its values. Runoff from precipitation mobilizes contaminants from impervious surfaces which are, in some case, transported directly to wetlands through stormwater drainage. Urban stormwater can be a significant source of contaminants to wetlands, although its overall importance needs to be …
