Selenium (SE) and its compounds are used in photographic devices, gun gluing, plastics, paints, anti-dandruff shampoos, vitamin and mineral supp., fungicides, and glass. It is also used to prepare drugs and as a nutritional feed supp. for poultry and livestock. This profile includes: (a) The exam¿n. of toxicologic info. and epidemiologic evaluations on SE to ascertain the levels of significant human exposure for the substance and the chronic health effects; (b) A determination of whether adequate info. on the health effects of SE is avail. to determine levels of exposure that present a significant risk to human health (SRHH); and (c) Ident¿n. of toxicologic testing needed to identify the types of exposure that may present SRHH.

This report characterizes the relationship of geology to groundwater occurrence and flow, with emphasis on determining the thickness of the valley-fill aquifer and water yielding properties of the fractured rock aquifers. Develops a water budget for the drainage basin and classifies the groundwater quality and identifies the likely sources of nitrate in groundwater.

This document is intended to provide an overview of the major components of surface and ground water quality and how these relate to ecosystem and human health. Local, regional and global assessments of water quality monitoring data are used to illustrate key features of aquatic environments, and to demonstrate how human activities on the landscape can influence water quality in both positive and negative ways. Clear and concise background knowledge on water quality can serve to support other water assessments.

Geochemical Techniques for Identifying Sources of Ground-Water Salinization offers a comprehensive look at the threat to the United States' freshwater resources due to salinization and outlines techniques that can be used to study the problem. The book reviews the seven major salt-water sources that commonly mix and deteriorate our fresh ground water (natural saline ground water, halite solution, sea-water intrusion, oil- and gas-field brines, agriculture effluents, saline seep, and road salting). Other topics covered are the characteristics of saltwater sources, geochemical parameters, and basic graphical and statistical methods that are frequently used in saltwater studies. The book also provides geographical charts showing the distribution of the major salt-water sources, illustrating which ones are potential sources in any given area in the United States.Geochemical Techniques for Identifying Sources of Ground-Water Salinization describes the individual geochemical parameters used in identifying salinization and the information on how and where to obtain them. This is an informative book for anyone interested in the present and future quality of our fresh-water supply.
