 Quick Bibliography Series 
 
 Bibliographies in the Quick Bibliography series of the
 National Agricultural Library (NAL), are intended primarily for
 current awareness, and as the title of the series implies, are
 not in-depth and exhaustive. However, the citations are a substantial resource
 for recent investigations on a given topic.  They also serve the purpose of
 bringing the literature of agriculture to the interested user who, in many
 cases, could not access it by any other means.  The bibliographies are derived
 from online searches of the AGRICOLA database.  Timeliness of topic and
 evidence of extensive interest are the selection criteria.  Send suggestions
 for Quick Bibliographies on water-related topics to wqic@nalusda.gov
 
 The author/searcher determines the purpose, length, and search
 strategy of the Quick Bibliography.  Information regarding these is 
 available from the author/searcher. An author and subject index is 
 provided along with the search strategy.
 
 This electronic bibliography is intended primarily to provide awareness of recent 
 investigations and discussions of a topic and is not intended to be in-depth and 
 exhaustive. The inclusion or omission of a particular publication or citation 
 should not be construed as endorsement or disapproval. (See all NAL Disclaimers.)

 Abstract:  During the last decade, studies carried out in
 several countries throughout the world have disclosed the
 presence of halogenated hydrocarbons and other potentially
 carcinogenic compounds in drinking water, causing public
 concern with respect to the quality of drinking water.
 Considering this problem, chlorinated drinking water from
 seven water treatment plants in Sao Paulo and from its water
 sources were tested for mutagenicity in the Ames/Salmonella
 assay. Different volumes of raw and treated waters were
 concentrated by XAD-2 resin, and eluted in methanol and
 methylene chloride. Organic extracts ressuspended in DMSO were
 assayed for dose response in Salmonella typhimrium strains
 TA98 and TA100, with and without metabolic activation, using
 the plate incorporation technique. Results showed higher
 incidence of mutagenic activity in water samples after
 chlorination than in raw water. The majority of positive
 responses were decreased by addition of metabolic activation,
 confirming the presence of direct-acting mutagens, produced
 during water chlorination, although significant mutagenicity
 was also observed in the presence of S9. Mutagenic levels
 ranged from 104 to 569 revertants/L in raw water, and in
 chlorinated drinking water, between 10 and 418 revertants/L.
 Based on the results obtained in this study, it is essential
 to study and identify mutagenic compounds evolving from the
 chlorination processes, and to determine, for water treatment
 plants with high incidence of mutagenic compounds, the
 procedures to avoid or eliminate this problem, as well as to
 establish an effective monitoring program.

 Abstract:  A 12-month study of runoff and suspended sediment
 yield was undertaken in a 0.93 km2 catchment in southern
 Chile. Rainfall and total runoff for the period December 1983-
 November 1984 were estimated at 2170 and 1150 mm,
 respectively, representing a runoff coefficient of 0.53.
 Suspended sediment concentrations ranged between 14 and 186 mg
 L-1, with an average of 71 mg L-1. Suspended sediment yield
 was estimated at 84 t or 90 t km-2 yr-1.

 Abstract:  Economic and physical simulation models were
 utilized to evaluate the effect of alternative soil and
 agricultural chemical management systems, implemented under
 the Conservation Reserve and Conservation Compliance Programs,
 on pesticides' leaching, and returns to fixed farm resources.
 Findings of the study show that the selection of appropriate
 soil and chemical systems may not only increase farm returns
 but may also result in a significant reduction in leaching and
 hence ground water degradation.

 Abstract:  Contamination of ground water from agricultural
 sources has been documented in a majority of the contiguous
 United States. In this study, we examine the potential for
 voluntary adoption of management practices that reduce risk of
 ground water contamination and discuss how farm operators'
 attitudes regarding the environment might affect the success
 of voluntary programs. Farmers' behavior and attitudes in
 Rockingham County, Virginia, and Big Spring Basin, Iowa,
 reveal that both groups consider the ground water issue to be
 a serious problem to which they are contributing. This
 awareness is a significant first step in prompting
 consideration of management practices that reduce the threat
 to ground water quality. We also found that the worst
 offenders"--that is, farmers applying nitrogen well above
 agronomic recommendations--were those with the least concern
 about the problem. If major shifts in farming practices are to
 occur voluntarily, major incentives or disincentives are
 needed Even though the concern about ground water quality is
 high, the documented risks perceived by farmers are not
 strongly convincing. The economic incentives for change are
 questionable at best. Voluntary adoption of best management
 practices is only one of several policy options. Ultimately,
 policies designed to reduce ground water contamination may
 need a mix of strategies, including economic incentives and
 disincentives, zoning and land use restrictions, environmental
 regulations, and bans on agricultural chemicals.

 Abstract:  The growing problem of nonpoint source ground water
 contamination from agricultural chemicals is conceptualized as
 an historical outcome of the production environment of
 capitalist agriculture in the Corn Belt. Chronic
 overproduction and ground water contamination reveal different
 aspects of the same technological treadmill. The debate over
 Iowa's 1987 Ground Water Protection Act symbolizes the
 contradiction between popular demand for clean water and
 structural limits on policymaking. Although the Act does
 provide for expanded research, education, and monitoring, a
 coalition of commercial farmers, local chemical dealers, and
 the national chemical industry defeated a tax on pesticide
 use. Analysis of alternate policy responses--Best Management
 Practices (BMPs), cross compliance, site-specific regulation
 of chemical use, and taxation of synthetic chemicals--reveals
 that all tend to founder on the same structural constraints.
 Without practical, profitable, low-input technologies that
 farmers, over time, would choose to adopt, both voluntary and
 regulatory approaches encounter major political or
 implementation difficulties. The public agricultural research
 agenda, therefore, emerges as a central control variable for
 ground water quality management and a central focus for
 political struggle.
