Contents Overview of major findings and implications -- NAWQA's approach to assessing water quality -- Background: environmental setting, hydrogeology, population, land use, and water use -- The hydrology of southwest basin-fill aquifers and how human alterations affect groundwater quality -- Quality of groundwater used for drinking and irrigation in southwest study basins -- Understanding where and why contaminants occur in southwest basin-fill aquifers.
Abstract Major findings: 1) Contaminants in water from one of every three drinking-water wells sampled are a potential human-health concern. 2) Arsenic and uranium derived from geologic sources are potential drinking-water concerns. 3) Dissolved-solids concentrations in groundwater are increasing in some areas. 4) Artificial recharge and groundwater withdrawals are moving contaminants to deeper parts of basin-fill aquifers.
