Book Synopsis Denitrification as a Means of Addressing Nitrate-contaminated Groundwater on Cape Cod, Massachusetts by : Kenneth Michael Motolenich-Salas
Download or read book Denitrification as a Means of Addressing Nitrate-contaminated Groundwater on Cape Cod, Massachusetts written by Kenneth Michael Motolenich-Salas and published by . This book was released on 1997 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The residents of Cape Cod face a problem of nitrate contamination of their groundwater (their primary source of drinking water) and their coastal and aquatic environments. Groundwater is the only source of drinking water on Cape Cod and the aquifer is defined as a "sole source aquifer" by the Safe Drinking Water Act. While many activities contribute nitrate (NO3-) contamination to groundwater, nitrate contamination from land application poses the greatest threat on Cape Cod. Only a few small areas on Cape Cod are sewered, and the majority of homes and businesses rely on septic systems. Increased urban development has increased the frequency of installation of septic systems. In many locations, the density of septic systems is greater than the natural ability of the subsurface environment to receive and purify system effluents prior to their movement into groundwater. Many of Cape Cod's environmental resources, including coastal receiving waters, marine embayments threatened with eutrophication, endangered wetlands, and Areas of Critical Environmental Concern (ACECs), are also threatened by nitrate-contaminated groundwater flowing into the coastal waters of Cape Cod, which are extremely sensitive to eutrophication from excess nitrogen loading. In order to address nitrate-contaminated groundwater on Cape Cod, solutions based on biological denitrification should be considered. In this work, these solutions are discussed and explored. First, the major sources of contamination and possible health and environmental effects are discussed. Second, the fate and transport of nitrate in the subsurface environment is analyzed, with a detailed discussion of the factors governing biological denitrification. Third, the current status of groundwater nitrate contamination on Cape Cod is detailed. Fourth, possible options, alternative septic systems and in-situ remedial schemes, which all use biological denitrification as a means of attenuating nitrate in septic system effluent, are presented. Lastly, a proposal for action to deal with nitrate contamination on Cape Cod and suggestions for future study and long-term action for domestic sewage are given, based on my opinion of the scientific and engineering aspects of the circumstances of the contamination.

Book Synopsis Chemolithotrophic Denitrification of Nitrate Contaminated Groundwater Using Sulfur-bearing Minerals by : John Sutton
Download or read book Chemolithotrophic Denitrification of Nitrate Contaminated Groundwater Using Sulfur-bearing Minerals written by John Sutton and published by . This book was released on 2019 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrate contamination in groundwater resources poses a serious threat, not only to the health of those who would drink it, but also as a potential nutrient for eutrophication. Current methods of nitrate removal can efficiently remove nitrate below 10 mg/L as nitrogen, but may require resources unavailable to small community water systems (SCWS). Sulfur-oxidizing biological denitrification is a promising alternative that may be more suitable for SCWS. Sulfur-oxidizing denitrification has previously been shown to have a high nitrate removal efficiency; however, it produces water high in sulfate. Utilization of sulfide-bearing minerals, rather than elemental sulfur as an electron donor, may yield similar nitrate removal efficiencies without the production of unwanted byproducts.

Book Synopsis Nitrate Contamination by : Istvan Bogardi
Download or read book Nitrate Contamination written by Istvan Bogardi and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nitrate content of drinking water is rising at an alarming rate in several regions of NATO countries and elsewhere in the world. The increase is due to lack of proper sewage treatment, and primarily to excess fertilizer application. Also, eutrophication in several coastal areas is triggered by high nitrate concentrations. The main purpose of this book is to integrate scientific knowledge related to exposure assessment, health consequences and control of nitrate contamination in water. The motivation is related to the magnitude, the possible adverse health effects, and the high cost of control ling nitrate contamination. Future research tasks are defined by an interaction among hydro logists, toxicologists and environmental engineers in an integrated framework for nitrate risk management. The target readership of this book is a mix of university colleagues, practitioners from both the private and public sectors and advanced graduate students working with the hydrological, health science or environmental engineering aspects of nitrate contamination. The main conclusions include: 1. For risk assessment purposes, knowledge and sufficiently accurate models are available to predict nitrate load and its fate in water under changes in land use. 2. Once agricultural exposure controls are implemented, the response times in ground water may be so long as to make controls unrealistic. 3. It is still unknown whether agricultural best management practice is a compromise between nitrate risk reduction and agricultural revenue. 4. The current drinking water guidelines of 10 mg/L NOrN need not be changed.
Book Synopsis Pollutants in Porous Media by : B. Yaron
Download or read book Pollutants in Porous Media written by B. Yaron and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unsaturated zone is the medium through which pollutants move from the soil surface to groundwater. Polluting substances are subjected to complex physical, chemical and biological transformations while moving through the unsaturated zone and their displacement depends on the transport properties of the water-air porous medium system. Pollution caused by human activities, agriculture, and industry, has brought about a growing interest in the role of the unsaturated zone in groundwater pollution. Due to the complexity and the multidisciplinary nature of the subject, it is being investigated by specialists from various scientific disciplines, such as soil physicists, chemists, biologists, and environmental engineers. This state of affairs has motivated the initiative taken by the Water Quality Commissions of IUPAC (the International Union of Pure and Applied Chemistry) and IAHS (the International Association of Hydrological Sciences) to convene an international workshop, which was organized and hosted by the Institute of Soils and Water of the Agricultural Research Organization in Bet Dagan, Israel in March 1983. The lecturers at the workshop were an invited group of specialists who are engaged in studying the many facets of the unsaturated zone, and the present book is a selection of their presentations. Each chapter of the book relates to a different aspect of the unsaturated zone.
