One perceived barrier to the implementation of new technologies in small drinking water systems is obtaining state regulatory agency approval. To investigate barriers as well as acceptance program status, experiences with new technologies, data needs for technology approval, and interest in a shared approach to acceptance of new technologies, a survey was sent to state regulatory agencies. The survey confirmed that new technologies for small systems are rarely considered by agencies. Key barriers encountered by states include an overall lack of staff time and training, insufficient data from vendors (including appropriate pilot test data), and lack of independent verification and certification. It was also found that some “emerging” technologies are more common than previously realized and that most states are interested in sharing data and are willing to collaborate to collect and evaluate performance data for new technologies. The next step is to identify how to share information nationwide.

Student interns are a resource that can increase the capacities of Extension professionals. Trained student interns based out of Nebraska Extension offices provided water and energy reduction recommendations to irrigators using center pivot irrigation systems. Follow-up interviews and a survey performed 1 to 3 years after the original assistance indicated impacts at levels similar to those garnered via previous assistance from Extension staff. In almost all cases, irrigators implemented soil water sensors, and the main motivations for doing so were financial. Recommendations for other improvements were infrequently implemented; however, as part of making those recommendations, the student interns collected fuel usage data that allowed for quantifying the energy and greenhouse gas impacts from reduced water use.
