Ground-water-quality and ground-water-level data were
collected in four unincorporated areas of Bernalillo County
during 1990-93. Twenty wells in the east mountain area of
Bernalillo County were sampled approximately monthly between
January 1990 and June 1993. The water samples were analyzed for
concentrations of chloride and selected nutrient species; many of
the samples also were analyzed for concentrations of total
organic carbon and dissolved boron and iron. Eleven wells
northeast of the city of Albuquerque, 20 wells in the Rio Grande
Valley immediately north of Albuquerque, and 30 wells in the Rio
Grande Valley immediately south of Albuquerque were sampled once
each between December 1992 and September 1993; all water samples
were analyzed for chloride and selected nutrient species, and
selected samples from wells in the north and south valley areas
were also analyzed for major dissolved constituents, iron,
manganese, and methylene blue active substances. Samples from 10
of the wells in the north and south valley areas were analyzed
for 47 selected pesticides. Field measurements of specific
conductance, pH, temperature, and alkalinity were made on most
samples at the time of sample collection. Water levels also were
measured at the time of sample collection when possible. Results
of the monthly water-quality and water-level monitoring in the
east mountain area of Bernalillo County are presented in
graphical form. Water-quality and water-level data collected from
the other areas are presented in tabular form.
