This book was released on 2002 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: An evaluation of polyacrylamides (PAM) for both erosion and turbidity control for construction sites was conducted in both the laboratory and the field. A laboratory screening was conduced for 11 PAMs on 13 sediment sources from North Carolina Department of Transportation (NCDOT) construction sites around North Carolina. In addition, a field test of two PAMs and two rates, with and without straw mulch and seeding, on a 2:1 fill slope, a 4:1 cut slope, and a 4:1 fill slope were performed.

This book was released on 2012 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency is in the process of developing a nationwide standard for turbidity in construction site runoff. It is widely expected that this standard cannot be met with conventional erosion and sediment control measures; consequently, innovative practices for managing sediment on construction sites must be developed. The objective of this research was to develop an understanding of how soil characteristics and polymer properties affect the amount of turbidity reduction that can be achieved through flocculation. The polymers used were PAMs, a proprietary product, and chitosan. The charge density of the PAMs ranged from 0% to 50% and the molecular weights ranged from 0.2 to 14 Mg/mol. A protocol for creating modified synthetic stormwater runoff for soil samples was developed and used on soils from seven construction sites. Particle size distributions were used to compare the modified synthetic stormwater runoff with grab samples of stormwater from one site and showed the synthetic runoff was representative of the actual runoff. Flocculation tests were performed on the synthetic runoffs with PAM and chitosan doses from 0.03 to 10 mg/L. The non-ionic PAM, proprietary product, and chitosan were found to be the most effective at reducing the turbidity of all the synthetic runoff below 200 NTU. The high molecular weight anionic PAMs were effective on only two of the seven synthetic runoff samples. Hardness tests were performed indicating interparticle bridging to be the bonding mechanism of the PAM. Electrophoretic mobility tests were performed on two of the soil suspensions and indicated the bonding mechanism of PAM to be interparticle bridging, and the bonding mechanism of chitosan to be a combination of charge neutralization and interparticle bridging. Tests showed as the charge density of the PAM increased, their effectiveness decreased.

Book Synopsis Turbidity Monitoring at Select Construction Sites by : Alex M. Aguilar
Download or read book Turbidity Monitoring at Select Construction Sites written by Alex M. Aguilar and published by . This book was released on 2012 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2009 the United States Environmental Protection Agency (EPA) proposed a numeric turbidity limit for stormwater runoff at construction sites. The proposed limit of 280 NTUs was stayed due to a miscalculation, and EPA has not released a new numeric limit for turbidity. Current Mississippi Department of Environmental (MDEQ) Water Quality Standards (WQS) required that turbidity 750 feet downstream from the point of discharge not exceed the background turbidity levels upstream of the discharge point buy [sic] 50 NTU. MDOT has no method of evaluation in place to measure turbidity at construction sites; and therefore, no background data are available to indicate how current erosion and sedimentation BMPs are performing with respect to potential increases in turbidity. Methods of analysis used in this report included the collection of turbidity data from seven sites where MDOT construction posed a potential threat to waters of the state.

Book Synopsis Highway Construction Site Erosion and Pollution Control Manual by : Richard Ray Horner
Download or read book Highway Construction Site Erosion and Pollution Control Manual written by Richard Ray Horner and published by . This book was released on 1990 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The size and length of highway construction projects have always created a relatively large potential to cause soil erosion problems. In recent years, regulations and public interest have stimulated awareness of these problems and efforts to address them. New techniques and products have been developed to reduce erosion at its source or interrupt the transport of eroded soil. However, these developments have not heretofore been systematically and comprehensively tested and compared to one another in effectiveness. The Washington State Department of Transportation and Federal Highway Administration funded research to perform such tests in order to improve the cost-effectiveness of highway construction site erosion and pollution control. The research involved literature review, experimentation at the laboratory and field scales, and compilation of cost data. This manual was produced to implement the results of this research. The manual presents criteria and guidelines relative to a number of slope covering techniques, silt barriers, sedimentation ponds, and construction management techniques. These criteria and guidelines cover method selection (based on applicability and relative cost-effectiveness), design, installation, and maintenance.

This book was released on 2018-09-14 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Common Grasses, Legumes and Forbs of the Eastern United States: Identification and Adaptation presents photographic identification of the most important grassland, turf, and noncrop plants, and their seeds to facilitate quick identification in the field. Unlike many publications that focus solely on floral identification, this book emphasizes vegetative identification as well to allow for accurate plant identification year-round. The book includes 23 forage legumes, 61 grasses, and more than 100 nonleguminous forbs found in pastures and grasslands of Eastern United States. In addition to identification of important species, the book describes other key characteristics such as adaptation, favorable and unfavorable soil types, seasonal growth patterns, and toxicity. For plants harvested for hay or silage or by grazing, the book also discusses cutting and grazing management, quality factors, and potential yields. Through its practical approach and comprehensive structure, Common Grasses, Legumes and Forbs of the Eastern United States is a valuable reference for farm advisors, teachers and students of agronomy, and for anyone interested in the dynamic relationship between plants and agriculture. Features full-color illustrations of both seed and plant, allowing for rapid identification at multiple stages of development Presents various identification methods and use cases for over 180 plants Details seasonal growth patterns and toxicity, as well as favorable and unfavorable soil types Discusses cutting and grazing management
