Increasing chloride concentrations are a threat to fresh ground-water sources in East Baton Rouge and West Baton Rouge Parishes, Louisiana. Large withdrawals at Baton Rouge have lowered water levels and altered flow patterns in most of the 10 aquifers that underlie the area. Prior to development, freshwater flowed southward to the Baton Rouge fault, an east-west trending growth fault that extends through Baton Rouge and across southeastern Louisiana. Aquifers south of the fault generally contain saltwater. Ground-water withdrawals north of the fault have created gradients favorable for the movement of saltwater from south of the fault into freshwater areas north of the fault. Water samples were collected from 152 wells during 2004-05 to document chloride concentrations in aquifers underlying East and West Baton Rouge Parishes. The background concentration for chloride in fresh ground water in the Baton Rouge area north of the Baton Rouge fault is generally less than 10 milligrams per liter. Chloride concentrations exceeded 10 milligrams per liter in one or more samples from wells north of the fault screened in the "600-foot," "1,000-foot," "1,200-foot," "1,500-foot," "1,700-foot," "2,000-foot," "2,400-foot," and "2,800-foot" sands. Comparison of the 2004-05 data with historical data indicated that chloride concentrations are increasing at wells in the "600-foot," "1,000-foot," "1,200-foot," "1,500-foot," "2,000-foot," "2,400-foot," and "2,800-foot" sands north of the Baton Rouge fault.

Fundamentals of Groundwater A thoroughly updated classic on the fundamentals of groundwater The second edition of Fundamentals of Groundwater delivers an expert discussion of the fundamentals of groundwater in the hydrologic cycle and applications to contemporary problems in hydrogeology. The theme of the book is groundwater, broadly defined, and it covers the theory and practice of groundwater—from basic principles of physical and chemical hydrogeology to their application in traditional and emerging areas of practice. This new edition contains extensive revisions, including new discussions of human impacts on aquifers, and strategies and concepts for sustainable development of groundwater. It also covers the theory of groundwater flow—including concepts of hydraulic head and the Darcy equation—and ground water/surface water interactions, as well as geochemistry and contamination. Readers will also find A thorough introduction to the techniques of water resource investigations and regional groundwater flow Comprehensive explorations of groundwater chemistry and its applications in regional characterization and assessments of health impacts Practical discussions of groundwater contamination and water sustainability more generally Fulsome treatments of newly emerged contaminants, like PFAS, pathogens, agricultural contaminants, methane, arsenic, uranium, and redox processes Perfect for undergraduate and graduate students taking courses in hydrogeology, groundwater, geoscience, applied geoscience, and groundwater and contaminant processes, Fundamentals of Groundwater also benefits environmental consultants, geochemists, engineers, and geologists.
