Summary of water-quality data for City of Albuquerque drinking-water supply wells, 1988-97

The City of Albuquerque has collected and analyzed more than 5,000
water-quality samples from 113 water-supply wells in the Albuquerque
area, including many drinking-water supply wells, since May of 1988.
As a result, a large water-quality data base has been compiled that
includes data for major ions, nutrients, trace elements, carbon,
volatile organic compounds, radiological constituents, and bacteria.
These data are intended to improve the understanding and management of
the ground-water resources of the region, rather than demonstrate
compliance with Federal and State drinking-water standards. This
report gives summary statistics for selected physical properties
and chemical constituents for ground water from wells used by the
City of Albuquerque for drinking-water supply between 1988 and 1997.
Maps are provided to show the general spatial distribution of selected
parameters and water types around the region. Although the values of
some parameters vary substantially across the city, median values for
all parameters included in this report are less than their respective
maximum contaminant levels in each drinking-water supply well. The
dominant water types are sodium plus potassium / carbonate plus bicarbonate
in the western part of the city and calcium / carbonate plus bicarbonate
in the eastern part of the city.
