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.

This book was released on 2012-12-06 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Tracers in Subsurface Hydrology synthesizes the research of specialists into a comprehensive review of the application of environmental tracers to the study of soil water and groundwater flow. The book includes chapters which cover ionic tracers, noble gases, chlorofluorocarbons, tritium, chlorine-36, oxygen-18, deuterium, and isotopes of carbon, strontium, sulphur and nitrogen. Applications of the tracers include the estimation of vertical and horizontal groundwater velocities, groundwater recharge rates, inter-aquifer leakage and mixing processes, chemical processes and palaeohydrology. Practicing hydrologists, soil physicists and hydrology professors and students will find the book to be a valuable support in their work.

This book was released on 2020 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bazile Creek flows north through Northeast Nebraska, entering the Missouri River just east of Niobrara, NE. The headwaters of the stream lie within the Bazile Groundwater Management Area (BGMA), a 1958 km2 region created in 2016 characterized by nonpointsource groundwater nitrate contamination. Elevated nitrate concentrations have been seen in the management area since the 1980s, and over time groundwater nitrate concentrations have continued to rise and affect an increasing number of wells. The BGMA contains parts of the Lower Niobrara, Lewis and Clark, Upper Elkhorn, and Lower Elkhorn Natural Resources Districts (NRDs). These NRDs have been working together to both monitor groundwater nitrate levels through periodic well sampling and curb increasing groundwater nitrate trends by educating landowners on methods to reduce fertilizer nitrogen loss through leaching and runoff. Although groundwater nitrate sampling in the Bazile Creek watershed has been continuous, surface water nitrate sampling has been infrequent and tributaries to Bazile Creek have never been sampled. Bazile Creek is a strongly gaining stream, indicating that a large percentage of its flow is derived from groundwater discharge. Nitrate concentrations in Bazile Creek have been slowly increasing, and nitrate in discharging groundwater is suspected to be the cause. This has led to questions about nitrate concentrations in Bazile Creek over time as well as throughout the watershed. This includes tributaries to Bazile Creek, which may all have similar nitrate concentrations or could vary between each other significantly. The source of nitrate entering Bazile Creek has not been determined, however it is assumed to be nitrogen containing fertilizers applied to the many agricultural fields nearby. A large quantity of well and excessively drained soils in the area indicate that fertilizer loss through leaching is probable. Livestock are present throughout the Bazile Creek watershed as well, indicating that manure-derived nitrate could also be making its way into the stream. Further complicating determinations on nitrate source is its potential seasonality, with manure-derived nitrate inputs being greatest in the spring and summer when frequent rainstorms create runoff that can transport manure off of fields into streams. This thesis aims to answer questions about nitrate dynamics and source within the headwaters of the Bazile Creek watershed. Surface water nitrate samples were collected over a period of 15 months from five tributaries and three locations on the main channel. Source seasonality was investigated through the collection of seasonal and rain event nitrate isotope samples, which also provided insight on denitrification rates. Results were then compared to subwatershed characteristics such as total area, land use, and soil drainage. Watershed-scale seasonal trends in discharge and precipitation were also investigated. These comparisons allow for conclusions to be made on nitrate source, primary transport pathways, and concentration seasonality.
