Six storm-water best management practices BMPs for treating urban rainwater runoff were evaluated for cost and effectiveness in removing suspended sediments and total phosphorus. Construction and annual operating and maintenance O and M cost data were collected and analyzed for dry extended detention basins, wet basins, sand filters, constructed wetlands, bioretention filters, and infiltration ...

Pollution from highway stormwater runoff has been an increasing area of concern. Many structural Best Management Practices (BMPs) have been implemented for stormwater treatment and management. One challenge for these BMPs is to sample stormwater and monitor BMP performance. The main objective of this study was to evaluate the feasibility of using polyurethane foam (PUF) passive samplers (PSs) f...

Urban stormwater contains a complex mixture of contaminants that can be acutely toxic to aquatic biota. Green stormwater infrastructure (GSI) is a set of evolving technologies intended to reduce impacts on natural systems by slowing and filtering runoff. The extent to which GSI methods work as intended is usually assessed in terms of water quantity (hydrology) and quality (chemistry). Biologica...

Cities must develop actions that reduce flood risk in the face of extreme rainfall events. In this study, dynamic resilience Gregorio catchment (São Carlos, Brazil) was assessed. The lacks environmental monitoring and suffers from recurrent floods. curves were made considering water depth drainage system as performance index, obtained by simulations with SWMM HEC-RAS. calibration extension perf...

Abstract Dredged Illinois River sand is nutrient poor and has low cation exchange capacity. Engineering this soil by adding amendments to increase retention may help sustain plant growth absorb contaminants when the used in bioslopes, bioswales, rain gardens. The objectives of study were compare physical chemical properties engineered soils derived from dredged combined with mixtures a locally ...

In order to determine whether shredded rubber mulches (RM) pose water quality risks when used in stormwater best management practices (BMPs) such as bioretention basins, batch leaching tests were conducted to identify and quantify constituents in leachates from RM such as metal ions, nutrients, total organic carbon (TOC), and aryl hydrocarbon receptor (AhR) activity (determined by the chemicall...

Recent university research has shown that a compost system can reduce storm runoff, sediment and nutrient loss, and increase vegetation and soil quality parameters relative to industry standard best management practices. State departments of transportation and construction companies have reported positive results in using compost as a filter media within filter socks. Compost used as a sediment...
