Abstract
In 2007, a 20-county area encompassing the Dallas-Fort Worth Metroplex was designated by the State as a Priority Groundwater Management Area (PGMA) in need of implementing strategies for groundwater conservation. The newly created PGMA’s population is expected to increase from 5.5 million in 2000 to 9.5 million by 2030 with projected water needs rising from 1,677 million m3 in 2000 to 3,034 million m3 by 2030 according to a study by Texas Commission on Environmental Quality (TCEQ). The Trinity Aquifer supplied 73% of the area’s groundwater in 2000, with the aquifer outcrop zone being highly susceptible to anthropogenic sources of contamination. Parker County is within the Upper Trinity Groundwater Conservation District (UTGCD) and is largely a rural area with many residents dependent upon private shallow, groundwater wells. Groundwater resources are under escalating pressure from urbanization, natural gas drilling, and predicted intensifying of droughts due to global climate change.l
