Santa Rita Underground Water Conservation District
Program Description
The Santa Rita Underground Water Conservation District, which covers most of Reagan County, has its
office in Big Lake. The district monitors changes in both the quality of ground water and the water levels
within its boundaries. To monitor the water quality, the district has equipped a small laboratory to
analyze for the presence of fecal coliform and monitor 12 other water quality parameters.
Two water quality monitoring programs have been initiated by the district. The first program is the
domestic well-water quality monitoring program which monitors the bacteriological and mineral content
of selected wells annually. In addition, all new wells are sampled and analyzed upon completion. The
analyses data are available upon request for any well having been tested within the district.
The second program is the baseline ground-water quality monitoring program. As wells are inventoried
with the district, samples are collected and analyzed for pH, specific conductivity, total dissolved solids,
and chlorides. This information is being used to establish baseline water quality throughout the district,
which will aid in the identification of possible ground-water degradation due to oil and gas production
within the district. Santa Rita U.W.C.D. also assist in working with the Railroad Commission of Texas
concerning oilfield related pollution or potential pollution of ground water.
South Plains Underground Water Conservation District
Program Description
The South Plains Underground Water Conservation District serves all of Terry County and part of
Hockley County. The district maintains a water quality laboratory at its office in Brownfield.
The district began sampling water wells for water quality in December of 1993. Samples were collected
from 103 domestic wells and analyzed for pH, specific conductivity, total dissolved solids, alkalinity,
hardness, chloride, fluoride, iron, nitrate as nitrogen, and sulfate. The same water wells will be sampled
on an annual basis in order to analyze trends in the change of ground-water quality over time, and to aid
the staff in the early identification of areas of ground-water degradation. An annual water quality report
will be prepared and distributed to the general public and appropriate agency officials.
The district offers free water quality analyses for residents within the district throughout the year at the
residents' request. Constituents analyzed include coliform bacteria as well as those previously listed.
The district has money budgeted for outside laboratory analysis should the need arise to confirm sample
results, or to test for parameters which the district is not capable of analyzing. Future plans includeannual testing for pesticides on a presence/absence basis.
The district began the sampling of irrigation wells for water quality analysis during the summer of 1994.
Approximately 45 wells were sampled that had been pumped for extended periods of time (7 days) in
order to form a more accurate water quality "picture" of the Ogallala aquifer underlying the district. The
district will expand this testing to include another 40 to 50 wells during the 1995 crop year. Thereafter,
wells will be monitored on a biennial basis.86
