Given the severity of recent droughts and the current discussions regarding climatic change, never before has groundwater fostered so much attention. This attention has provided a much greater need for regulators, scientists, and engineers to more fully understand and protect the quality of our groundwater resources. To that end, the NGWA Aquifer Protection Interest Group presents abstracts related to the technical, policy, or regulatory aspects of protecting the quality of groundwater resources, particularly those source waters used for drinking purposes. Presentations include source water delineation methods; groundwater monitoring strategies for aquifer protection; engineered control technologies to prevent groundwater contamination; assessing risks to groundwater; identifying and/or managing potential contaminant sources in source water protection areas; regulatory aspects of aquifer protection; and education and other management strategies for groundwater protection.
