Abstract:
Four parameters were examined to detect changes in ground-water quality in the Hueco bolson near El Paso, Texas. Sulfate (SO4), chloride (CL), nitrate (NO3), total dissolved solids (TDS) and pumpage data from 148 wells from 1970 through 1985 were used in the investigation. Regression analyses and contouring were used to determine if changes occurred with time, pumpage, depth or space. Results from the statistical tests indicate CL and TDS increase with time and average values of CL, NO3 and TDS increase with total pumpage. Contour maps of the 4 constituents for the years 1970, 1975, 1980 and 1985 show a spatial increase in concentration. Contour maps of the regression coefficients pinpoint areas where the concentrations of the parameters are increasing with time. Degradation of the water quality appears to be due to several sources: urban runoff; leakage of saline water; lateral intrusion of saline water; and industrial pollution.
