NIFA Northern Plains and Mountains Regional Water Program
The goal of the Northern Plains and Mountain Regional Water Program is to integrate water research, education, and extension resources of the land-grant universities and to partner with stakeholders to develop and deliver knowledge-based programs addressing protection and improvement of water resources.  This website houses resources to provide you with general information regarding hydraulic fracturing, water quality testing guidelines, and frequently asked questions.

Colorado Water and Energy Research Center
Research group from Colorado studying the connections between water and energy resources.  They have developed a guide for water well users titled ‘Monitoring Water Quality in Areas of Oil and Natural Gas Development’.  The website has a picture slide show which walks you through the steps of collecting a water sample.  This is all available online at: http://cwerc.colorado.edu/ 

FrackingSENSE lectures:  http://vimeo.com/cuoutreach/videos
Start with "What we know and don't know about the risks of oil and natural gas development on water quality," by Joe Ryan, professor of civil, environmental, and architectural engineering at CU–Boulder. http://vimeo.com/69253030
