Municipal wells San Jose number 3 and San Jose number 6 were decommissioned in 1981 due to contamination with low levels of organic solvents, halocarbons and aromatics. These wells were plugged and abandoned in September 1994. The site remains on the Superfund site list with on-going remedial actions to contain, capture and reduce the concentration of the contaminant plume within the ground water.[5]

Incorporation efforts
Presently, the South Valley is an unincorporated area in Bernalillo County that lies south of the city limits of Albuquerque. In January 2010, a special election was held in the South Valley to decide whether or not the region should incorporate into a city, to be named Valle de Atrisco.[8] Voters in the South Valley overwhelmingly rejected incorporation by a 93 to 7 percent margin during the special election on January 5, 2010. Opponents to incorporation cited the potential costs (and tax burden for residents) for providing for education, public works, police and fire services in the South Valley because Bernalillo County would no longer be providing these services to the community following incorporation.[9]
