Author Description

"This CD-ROM contains a report and 10 maps at 1:100,000-scale in easily readable PDF format that address ground-water quality in Cache Valley's basin-fill aquifer and provide recommendations for septic tank soil-absorption-system densities based on potential water-quality degradation associated with usage of these systems. The maps are described in detail in the report and show total-dissolved-solids, nitrate, iron, sulfate, and chloride concentrations, and recommended septic tank soil-absorption-system densities."--sticker on back of case.
