Book Synopsis Soil Amendments and Environmental Quality by : Jack E. Rechcigl
Download or read book Soil Amendments and Environmental Quality written by Jack E. Rechcigl and published by CRC Press. This book was released on 1995-09-25 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive and balanced overview of soil amendments and their effect on the environment. It encompasses both positive and negative aspects of chemical fertilizers that supply nitrogen, phosphorous, sulfur, lime, micronutrients, and trace metals. Pros and cons are discussed with respect to the optimal and the most environmentally sound use of soil amendments, and guidance is provided on how to minimize the environmental effects of amendments. Natural fertilizers, including manure, sludge, fly ash, phosphogypsum, and byproduct gypsum are also discussed. Alternative agronomic practices and biotechnology that ameliorate or minimize potential adverse effects of fertilizer use are examined in detail. This authoritative and up-to-date treatise is multidisciplinary in nature and international in scope, a powerful reference tool for researchers, a thorough guide for practitioners and policy makers, and an excellent text book for academic courses.

Book Synopsis Soil-based Wastewater Treatment by : Jose A. Amador
Download or read book Soil-based Wastewater Treatment written by Jose A. Amador and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our book addresses the needs of practitioners, engineers, scientists, regulators, resource managers, planners, and others with a need to know about septic systems. It arose after discussions about the need for a text that integrated current understanding of the hydrologic, physical, chemical, and biological processes involved in the treatment of wastewater using soil. In our experience, people working with septic systems – ourselves included – have a fragmented understanding of what these systems are, how they function, how wastewater moves through soil, how and which pollutants are removed, and how these systems impact the environment and public health. The relevant information is scattered across disciplines, information sources and audiences. This book is an attempt to collect and integrate this information in one place, and provide a scientific framework for understanding soil-based wastewater treatment.
Book Synopsis Physics of Wastewater Flow and Pathogen Transport Processes from a Soil-based At-grade Effluent Treatment System and Associated Groundwater Contamination Risks in Alberta, Canada by : Amanuel Oqbit Weldeyohannes
Download or read book Physics of Wastewater Flow and Pathogen Transport Processes from a Soil-based At-grade Effluent Treatment System and Associated Groundwater Contamination Risks in Alberta, Canada written by Amanuel Oqbit Weldeyohannes and published by . This book was released on 2015 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding of wastewater flow and transport processes and treatment effectiveness through the soil-absorption field of soil-based wastewater treatment systems remains a challenge. In addition, Alberta regulators and the on-site wastewater industry wanted to quantify the effectiveness of the new LFH At-grade soil-based wastewater absorption and treatment system design. An extensive field research program was executed at Wetaskiwin Rest Stop, Central region of Alberta, a site that has been receiving secondarly treated and ultraviolet disinfected effluent via pressurized effluent distribution at-grade laterals since 2007. The specific objectives were to investigate: i) hydrologic response to effluent infiltration from at-grade line sources under shallow groundwater conditions, ii) fate and transport of pathogens under boundary conditions typical of on-site water treatment systems (OWTS), and iii) groundwater contamination risks associated with OWTS. Following site characterization, field-scale tracer experiment was conducted using E.coli and Bromide as step and pulse inputs respectively. Groundwater response to effluent infiltration, wastewater plume movement, E.coli and virus concentrations were monitored in nests of monitoring wells over time. Finally, using the field measurements, HYDRUS 2D was used to investigate groundwater contamination risks associated with OWTS. Considering the existing regulatory requirement of 7-day effluent travel depth through the vadose zone that has been established in Alberta, a residence time assumed to be enough for pathogens attenuation in the vadose zone, weekly cycle hydrologic responses were interpreted. Findings indicated: i) significant hydrologic response to effluent infiltration from at-grade line sources at a weekly scale, ii) effluent reaching the groundwater for approximately 15% of the time in the spring and summer periods when effluent loading rate of ≥5 cm3 cm-2 d-1 encountered a groundwater at ≤0.5 m below the ground surface. These conditions also coincided with the significant 7-day cycle of the effluent input function due to traffic on the highway and use of the facilities. The results suggest consideration of both surface effluent loading and regional hydrologic conditions when designing at-grade wastewater treatment systems to minimize potential groundwater contamination risks; iii) the vadose zone of ≥0.88 m thick, the vertical separation between the at-grade lines and the top of the groundwater level, filtered E.coli bacteria that were present in the infiltrating effluent to acceptable levels achieving the 7-day effluent travel depth design criteria, however it didn't perform well for some viruses, and iv) initial groundwater depth from the surface is critical for designing at-grade effluent treatment systems. Under the prevailing site boundary conditions and assuming a homogenous medium, a loading rate up to 15 cm3 cm-2 d-1 poses less threat when the initial depth to groundwater is at ≥2 m. In practical terms therefore, matching effluent loading rate vis-a-vis the effluent receiving site characteristics is critical particularly during the spring snow melt and summer period. In addition to the design criteria of OWTS, inclusion of performance criteria as standard of practices for these systems is suggested. The findings presented in this thesis contribute significantly to the understanding of wastewater flow and transport under boundary conditions typical of OWTS and shallow groundwater conditions.
