This book was released on 1979 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose was to determine extent that individuals near spray irrigation sites are exposed to microorganisms in wastewater aerosols. Report covers Phase II - a monitoring effort from May 1976 to April 1977 of a spray irrigation site utilizing unchlorinated secondarily-treated wastewater from biofiltration treatment process. Objectives included an in-depth pathogen screen of wastewater, establishing the relationship between pathogen levels and traditional indicator organisms, monitoring microorganisms in air within 600 meters of the spray source, and development/validation of a microbiological dispersion model for predicting pathogen aerosol concentrations. Effluent was monitored for microbiological, chemical, and physical characteristics; extensive microorganism and dye aerosol samples were collected (77 aerosol runs). Enteroviruses were detected in air, but at a very low concentration. Conclusions: There is considerable underestimation of pathogen aerosol levels when using traditional indicators to predict human exposures to enteroviruses. Microbiological dispersion model may be used with minimal monitoring to estimate exposure. There is little correlation between wastewater levels of traditional indicators and pathogens. Microbiological wastewater aerosols are generated by spray irrigation, do survive aerosolization and can be transported to nearby populations.

Available in PDF, EPUB and Kindle. Book excerpt: The second phase of a field study to measure microbiological aerosol disemination by the spray irrigation mode of land wastewater application was conducted at Ft. Huachuca, AZ. Chlorinated and unchlorinated secondarily treated wastewaters were sprayed in periods of high and low sunlight intensity, and bacterial and virus aerosols were sampled. Predictions of long distance migration and aerosol dispersal of total aerobic bacteria and enteric virus (utilizing seeded coliphage f2 as a model), were emphasized.

This book was released on 1994-02-01 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: As demand for water increases, water managers and planners will need to look widely for ways to improve water management and augment water supplies. This book concludes that artificial recharge can be one option in an integrated strategy to optimize total water resource management and that in some cases impaired-quality water can be used effectively as a source for artificial recharge of ground water aquifers. Source water quality characteristics, pretreatment and recharge technologies, transformations during transport through the soil and aquifer, public health issues, economic feasibility, and legal and institutional considerations are addressed. The book evaluates three main types of impaired quality water sourcesâ€"treated municipal wastewater, stormwater runoff, and irrigation return flowâ€"and describes which is the most consistent in terms of quality and quantity. Also included are descriptions of seven recharge projects.

Available in PDF, EPUB and Kindle. Book excerpt: This book argues, that without methods, there can be no research. Effective research requires effective methods, not always easy to come by. The development of methods in environmental virology became a focus of growing interest about two decades ago. Progress has been significant since that time in pure experimental systems, where there are no interferences, consistent high recoveries of viruses from environmental waters has been achievable for some time. In the natural environment, however, in relatively clean waters, substances such as humic and fulvic acids interfere with viral recoveries and average recovery rates probably do not reach 20%. With sewage sludges and shellfish, recoveries are undoubtedly much lower. Yet, even relatively low viral recovery rates have made possible the detection of viral hazards in drinking waters. The hazards that exist are undoubtedly much greater than those demonstrated with the relatively inefficient methods inefficient methods developed thus far. Improving methods, as they are developed in the years to come, will undoubtedly bring the true extent of the hazards into better perspective.
Download or read book Land Application of Wastewater Sludge written by T. M. Younos and published by ASCE Publications. This book was released on 1987-01-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Task Committee on Land Application of Sludge of the Committee on Water Pollution Management of the Environmental Engineering Division of ASCE. This report presents research on the land application of wastewater sludge, especially quantitative and qualitative aspects of soil-sludge interaction. Each year, approximately 6.2 million dry metric tons of wastewater sludge are produced by municipal wastewater treatment facilities in the United States. The annual sludge production is expected to reach 12 million dry metric tons by the year 2000. Sludge use and disposal options include incineration, ocean disposal, marketing of processed sludge, landfilling, and land application. Land application of sludge is achieved by spreading the sludge over the ground surface or incorporating it within the topsoil by injection, disking, or plowing. Sludge is applied to agricultural and forest lands for its nutrient value and to disturbed areas for soil amendment and reclamation purposes. At present, land application is the logical alternative because of its environmental and economic advantages over the other methods. Topics include: mechanisms for the removal of nitrogen and phosphorus, the role of trace elements, hydrologic effects of soil-sludge interaction, use of municipal sludge to reclaim mined land, and health effects. The report concludes with recommendations for future research.
