摘要

Associations between groundwater quality and land use were evaluated in the southeastern Gulf Cost Aquifer, Texas. Data from 19 234 oil/gas wells and 256 water wells were mapped with a Geographic information system (GIS) and statistically analyzed. Water wells near oil/gas wells had Significantly higher levels of chloride, bromide, and total dissolved solids (TDS). Bromide-chloride Ratios were also higher at water wells near oil/gas wells. Shallower water wells had significantly Higher chloride, bromide, TDS, and nitrate concentrations.
