Abstract

Upward-leaking brine, from a confined aquifer at the base of the Rustler Formation, mixes with fresher water in a shallow aquifer , resulting in discharge to the Pecos River in southern Eddy County, New Mexico, of about 0.5 cubic feet per second of saturated brine. Pumping brine from the aquifer at a rate greater than 0.5 cubic feet per second lowered the potentiometric head in the confined aquifer. From July 22, 1963, through December 1968, approximately 3,878 acre-feet of brine had been pumped into the Northeast Depression. The depression leaked brine to the Pecos River. Water downgradient of the depression increased in specific conductance ranging from 1,500 to 99,400 milligrams per liter chloride and water levels near the depression increased over 3 feet from 1963 to 1968. For water years 1952-63, the Pecos River gained about 240 tons per day of chloride in the reach from Malaga gaging station to Pierce Canyon Crossing. The average chloride gain to the Pecos River from July 1963 to August 1966 was 167 tons per day; the 1967-68 gain increased to 256 tons per day after a major flood in August 1966. (USGS)
