This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Raisin River watershed, located approximately 130 kilometres east of Ottawa, is the site of an environmental project examining the groundwater quality and contamination potential of a fractured bedrock aquifer in an agricultural basin discharging to the St. Lawrence River. Groundwater quality was monitored in five tile drains, four piezometers, and thirteen domestic wells over a period of 14 months (May-94 to June-95). Temporal variations in total dissolved solids (TDS), water level and major element concentrations, as well as fluctuations in dissolved organic carbon (DOC), $\delta\sp2$H and $\delta\sp $C were used to distinguish between regionally recharged groundwaters and recharge occurring by local infiltration through agricultural fields. Nitrate, agricultural pesticides, and heavy metals were analyzed as the principal components of groundwater quality. Water level, dissolved solids, $\delta\sp2$H, and $\rm\delta\sp C\sb{DIC}$ fluctuated according to seasonal change. Springtime showed high water levels coupled with depleted $\delta\sp2$H values. In addition, nitrate and DOC values were elevated due to local infiltration through the soil zone into the bedrock aquifer. The $\delta\sp $C values show that recharge contributions from (i) bedrock recharge areas, and (ii) infiltration through cultivated fields, vary on a seasonal basis. Spring and summer periods are dominated by recharge through cultivated fields where $\delta\sp $C values are governed by infiltration of C$\sb4$ plant (corn) carbon. Contributions of local recharge during the fall and winter months are reduced. The watershed's susceptibility to groundwater contamination is considered high since the aquifer responds to seasonal climatic variations. The mean residence time of these groundwaters is in the range of several months, based on cross-correlations between air temperature and $\delta\sp2$ values of Raisin River waters. The most potentially harmful times of year occur during rapid groundwater infiltration during the spring and periods of high precipitation. The effect of tile drains in diverting agro-contaminants to the Raisin River contributes to overall good bedrock groundwater quality as tile drainage effluent shows elevated concentrations of pesticides, nitrate, and trace metals.

Book Synopsis Pesticides and Groundwater Quality by : National Research Council
Download or read book Pesticides and Groundwater Quality written by National Research Council and published by National Academies Press. This book was released on 1986-02-01 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticides in groundwater can contaminate drinking water and threaten the health of communities. How does this contamination occur and what should be done about this pressing problem? This new book uses a case-study approach to describe the discovery of the problem in four major agricultural states, to summarize the most recent data on the problem, and to review the status of the problem from both technological and policy perspectives. It also addresses the controversial questions of what levels of residues are acceptable, who should bear the costs of drinking water that is already contaminated, and how federal scientific resources can best be used to aid state initiatives in addressing this problem.

In the Kesterson case, for example, science can determine the concentrations of selenium that are toxic to waterfowl or define the relationship between increasing salt concentrations and crop production. But science cannot judge which is more valuable, the crop or the waterfowl, nor can science assign values to predicted outcomes. As was discussed in Chapter 3, it is in this sense that the parallel involvement of ethics, law, economics, politics, and public policy has made the problems in the San Joaquin Valley particularly difficult to define and solve. Finding solutions to environmental problems like those caused by irrigation drainage requires difficult choices. Thus the equity and effectiveness of the process used to seek, evaluate, and implement potential solutions become critically important. For this reason, good study design is essential. Concurring with an earlier National Research Council Study, Ecological Knowledge and Environmental Problem-Solving: Concepts and Case Studies (National Research Council, 1986), the framework presented here is "in essence, an admonition to think before acting and to use established scientific principles." Although that National Research Council study focused on the environmental impact assessment process, this committee's activities have strongly reinforced many of the same messages. This report also reinforces many points about sound study design for long-term monitoring as were highlighted in another National Research Council study, River and Dam Management: A Review of the Bureau of Reclamation's Glen Canyon Environmental Studies (National Research Council, 1987). The purpose of this chapter is to highlight key elements that the committee believes are essential in addressing...

This book was released on 2020-12-04 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.

This book was released on 2019-06-18 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space (National Academies Press, 2018) provides detailed guidance on how relevant federal agencies can ensure that the United States receives the maximum benefit from its investments in Earth observations from space, while operating within realistic cost constraints. This short booklet, designed to be accessible to the general public, provides a summary of the key ideas and recommendations from the full decadal survey report.
