  6. Future Study Water Resources Development Act

  7. Objective: to provide necessary hydrologic information to effectively plan for future water-resources development • Conceptual understanding of aquifer system • Groundwater availability • Groundwater quality and susceptibility to contamination • Recharge sources, flow paths, residence times • Optimizing management strategies • Evaluation of additional groundwater resources • Evaluation of potential effects of future development on current resources and water supply

  8. Source Protection • HB 40 • Need

  9. HB 40 • Original Bill required all Counties to adopt an ordinance protecting drinking water sources • No later than May 3rd 2010 • Bill was amended 2009 only requiring Counties of the 1st & 2nd Class to adopt an ordinance protecting drinking water sources • Bill no longer applies to Grand County

  10. Need for Source Protection • GWSSA feels there is a need and would like to see a County wide plan implemented • Moab City and GWSSA both have a Source protection plan • GWSSA also feels that it would be in both the County’s and the City’s best interest to adopt a common plan
