Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of this field study was to evaluate the potential effectiveness of vegetated highway embankments as a stormwater runoff best management practice (BMP) for retention of metals, polycyclic aromatic hydrocarbons (PAHs), and particulates. The study characterized roadway sediment particulate matter, annual pollutant mass loading, and long-term pollutant retention for three field sites in eastern Kansas. The field study indicated that pollutant retention was primarily a surficial phenomenon, limited to the top 0 to 2 inches of highway embankment soils. Effectiveness of vegetated embankments for net particle retention was found to be greater than 70% for particles of 0.020 mm or greater. The 18 ft long vegetated highway embankments evaluated in this study were effective stormwater runoff BMPs for zinc with 42 to 100% long-term pollutant mass retention. Moderate performance was observed for pyrene and chrysene with 20 to 100% mass retention. Vegetative embankments were less effective for copper and benzo(a)pyrene with 9 to 42% mass retention. The key benefits of utilizing highway embankments for runoff control include cost-effectiveness relative to other engineered systems and compatibility with roadway design and maintenance requirements. While specific pollutant mass retention was observed to be variable and dependent on metal or PAH properties in runoff, the overall result is a significant reduction in pollutant mass to the local watershed, particularly when embankments are greater than 30 to 45 ft in length.

Download or read book Stormwater Management for Transportation Facilities written by Shaw L. Yu and published by Transportation Research Board. This book was released on 1993 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to highway design engineers, maintenance engineers, environmental personnel, administrators, and others responsible for the design, operation, and maintenance of stormwater management for highways and ancillary facilities. Information is presented on the basic hydrology needed to assess stormwater impacts and on the effectiveness of stormwater management techniques. Designers of highway facilities must consider stormwater management requirements within the context of both localized runoff impacts, as well as downstream effects of runoff. This report of the Transportation Research Board describes the management of both stormwater quantity and stormwater quality. Stormwater quantity includes an overview of methods of estimating runoff and management control practices. Stormwater quality management includes discussions of the most prevalent pollutants and best management practices (BMP) to minimize pollutants from transportation facilities. Various types of structural and non-structural methods are described, including their design considerations and efficiencies. Several stormwater management models are described, with special concern for highway applications. Highlights from the 1990 National Pollutant Discharge Elimination System (NPDES) permits are presented.
Download or read book Vegetated Biofilter for Post Construction Storm Water Management for Linear Transportation Projects written by Gayle F. Mitchell and published by . This book was released on 2010 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vegetated biofilter is a low impact development technique that can be integrated into stormwater management of linear transportation systems and capitalize on the natural environment to mitigate stormwater. A 4 ft (1.2 m) wide by 14 ft (4.3 m) long prototype vegetated biofilter was constructed on a moveable frame. Artificial runoff was delivered to each of three grass beds for comprehensive tests at slopes and flow rates as follows: 8:1, medium; 4:1, medium; 2:1, medium; and 2:1, high. The medium and high flows represented storm runoff events typical in Ohio. First, baseline tests were performed to obtain concentrations of constituents native to the biofilter. Artificial runoff, formulated with metals, native soil, and motor oil, was applied to one bed at a "high" concentration for the first part of the event, followed by a "medium" concentration; a second bed received "medium" followed by "low" concentration runoff, and the third bed received "low" concentration followed by tap water. During the simulated storm events, samples were obtained from the inlet, surface runoff, and underdrain and analyzed for total and dissolved metals, TSS, and oil and grease. Prior to and at the end of testing, cores were extracted from the bed, separated into soil, roots and grass, and each component analyzed for metal content per mass of material. The two beds receiving the initial high and medium concentration flow performed well and removal of 7 total metals and TSS was above 75%. Removal of oil ranged from 30% to over 90%. The bed receiving low concentration runoff, which was near the baseline levels for constituents, had mixed performance of removals ranging from none to above 90%, illustrating the difficulty of any BMP to treat a relatively clean influent. Metals above background levels were found primarily in the first half (7 ft, 2.1 m) of each bed. Soil particles in the influent flow of the first test in each bed, tagged with La, were not resuspended in subsequent tests and were not measured at any significant concentration in the outlet surface flow.

Download or read book Evaluation and Management of Highway Runoff Water Quality written by G. Kenneth Young and published by . This book was released on 1996 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this manual is to gather and to synthesize the results of past documentation and research on highway stormwater runoff into a single-volume user's manual on water quality impact assessment and mitigation. The manual will be useful to highway designers and environmental professionals by presenting the available and appropriate impact prediction and mitigation tools for use during highway project planning and development activities. The development of this document had three components: a literature search on existing research results and operational findings on highway stormwater runoff that identifies existing water quality impact assessment and mitigation techniques; interviews with highway practitioners concerning the use of research results including maintenance of mitigation measures; and synthesis of the accumulated information into this single-volume, practical guidance manual. This manual is intended to be a self-contained desk reference for highway practitioners. An extensive bibliography is included, and the mathematical nomenclature is unified among the sections.
