The Colorado Cooperative Program for Environmental Health Assessments (CCPEHA) was initially contacted in July of 2007 to assist with community concerns regarding consumption of fruits and vegetables from domestic gardens irrigated with contaminated groundwater. After a preliminary investigation of the available environmental data, including sample data generated from residents' fruits and vegetables, it was decided that a health consultation should be conducted to address the potential public health hazards associated with exposure to groundwater contaminants. This health consultation focuses on residential exposures to groundwater contaminants in the Fairmont neighborhood.
This report describes the location, physical setting, hydrochemistry, and geothermometry of ten thermal springs or wells in the Rico Group and West Fork Group of the Dolores River areas of Colorado. Geothermometry is a technique used to estimate the subsurface temperature of a geothermal reservoir, or the most recent temperature at which the water has undergone chemical reactions. This information is useful in geothermal exploration when considering the resource potential of an area. Statewide, Colorado has a significant geothermal power generation potential, and the area centered on the Town of Rico is among the highest heat flow areas in the State.
