Groundwater, 2004
AbstractAdverse impacts on the health of some fish populations, such as skewed sex distributions, have been noted in surface waters and in laboratory experiments with relatively low concentrations (above 25 ng/L) of natural estrogen (17 β‐estradiol—E2).

Symposium on the Application of Geophysics to Engineering and Environmental Problems 2006, 2006
In this presentation, we discuss geophysical methods for general vulnerability mapping of aquifers. The vulnerability of aquifers is to a large degree determined by the content of clay minerals in the near surface geology. Clay minerals have a large cation exchange capacity (CEC) and clayey sediments reduce the infiltration speed thus reducing the ...

Integrating Borehole Logs and Aquifer Tests in Aquifer Characterization
Groundwater, 2000AbstractIntegration of lithologic logs, geophysical logs, and hydraulic tests is critical in characterizing heterogeneous aquifers. Typically only a limited number of aquifer tests can be performed, and these need to be designed to provide hydraulic properties for the principle aquifers in the system.

Subsurface water, or groundwater, is a term used to denote all the waters found beneath ground surface. However, groundwater hydrologists, who are primarily (but not exclusively) concerned with the water contained in the zone of saturation (Subs. 1.1.1), often use the term ‘groundwater’ to denote water in only this zone. In this book, we adhere to this

Estimating Groundwater Mounding in Sloping Aquifers for Managed Aquifer Recharge
Groundwater, 2017AbstractDesign of managed aquifer recharge (MAR) for augmentation of groundwater resources often lacks detailed data, and simple diagnostic tools for evaluation of the water table in a broad range of parameters are needed. In many large‐scale MAR projects, the effect of a regional aquifer base dip cannot be ignored due to the scale of recharge sources (

Denitrification in a Deep Basalt Aquifer: Implications for Aquifer Storage and Recovery
Groundwater, 2013AbstractAquifer storage and recovery (ASR) can provide a means of storing water for irrigation in agricultural areas where water availability is limited. A concern, however, is that the injected water may lead to a degradation of groundwater quality. In many agricultural areas, nitrate is a limiting factor. In the Umatilla Basin in north central Oregon,

Aquifer tests are the most appropriate method to determine the hydraulic behavior of an aquifer and the distribution of the hydrodynamic parameters that govern such behavior. This chapter illustrates the different type of aquifer tests (i.e., pumping, recovery and slug tests) and how to plan, execute and interpret them.

Advanced aquifer characterization for optimization of managed aquifer recharge
Environmental Earth Sciences, 2014Managed aquifer recharge (MAR) will play an increasingly important role in solving water scarcity. The performance of MAR systems depends primarily upon local hydrogeology. Greatest opportunities for improvement in the implementation of MAR systems lie in the targeted application of conventional and advanced technologies to improve aquifer ...

The Guarani Aquifer System and the International Law of Transboundary Aquifers
International Community Law Review, 2011AbstractArgentina, Brazil, Paraguay and Uruguay signed the Guarani Aquifer Agreement on 2 August 2010. This is the first international treaty regarding the management of a specific transboundary aquifer to have been adopted after the UN International Law Commission (UNILC) adopted the Draft Articles on the Law of Transboundary Aquifers, which have been

The unplanned and non-scientific development of ground water resource to meet the exponentially increasing water demand for various societal uses is leading to stress on the aquifer system and over-exploitation of this precious natural resource.
