Water-quality and ground-water-level trends, 1990-99, and data collected from 1995 through 1999, East Mountain area, Bernalillo County, central New Mexico

Abstract

Bernalillo County officials recognize the importance of monitoring water quality and groundwater levels in rapidly developing areas. For this reason, water-quality and ground-waterlevel data were collected from 87 wells, 3 springs, and the Ojo Grande Acequia in the east mountain area of Bernalillo County between January 1990 and June 1999. The water samples were analyzed for selected nutrient species; total organic carbon; major dissolved constituents; methylene blue active substances; and dissolved arsenic. Analytical results were used to compute hardness, sodium adsorption ratio, and dissolved solids. Specific conductance, pH, air and water temperature, alkalinity, and dissolved oxygen were measured in the field at the time of sample collection. Groundwater levels were measured at the time of sample collection. From January 1990 through June 1993, water-quality and groundwater level data were collected monthly from an initial set of 20 wells; these data were published in a 1995 report. During 1995, water samples and groundwater level data were collected and analyzed from the initial set of 20 wells and from an additional 31 wells, 2 springs, and the Ojo Grande Acequia; these data were published in a 1996 report. Additional waterquality and groundwater level data have been collected from sites in the east mountain area: 34 wells and the acequia during 1997,14 wells and 1 spring during 1998, and 6 wells during 1999. Water-quality and groundwater level data collected in the east mountain area during 1995 through 1999 are presented in tables. In addition, temporal trends for groundwater levels, concentrations of total and dissolved nitrite plus nitrate, concentrations of dissolved chloride, and specific conductance are presented for 20 selected wells in water-quality and water-level hydrographs.

Precipitation, Ground-water Hydrology, and Recharge Along the Eastern Slopes of the Sandia Mountains, Bernalillo County, New Mexico

“…Seasonal responses to snowmelt and monsoon periods are noted for most of the sites with monthly data from 1990 to 1993. Similar, qualitative analysis of these hydrographs for that time period is discussed in Kues and Garcia (1995), Rankin (2000), and Blanchard (2004). Several wells within proximity of each other indicate different patterns of waterlevel response to recharge events; wells 30, 31, 33, and 34 near Sandia Park ( fig.…”

Estimates of groundwater recharge rates and sources in the East Mountain area, Eastern Bernalillo County, New Mexico, 2005-12

“…Titus (1980) provided the first comprehensive investigation into the hydrogeology of the East Mountain area, including water quality and well yield. Jenkins (1982), Kues (1990), White and Kues (1992), Kues and Garcia (1995), Rankin (1996Rankin ( , 2000, Blanchard and Kues (1999), Blanchard (2003, 2004), McGregor (2007, and Johnson and Campbell (2008) presented water-level and water-quality data for wells and springs in the area.…”
