Target Audience:County officials and residents of Gwinnett County, GA. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?This project served as a MS thesis, providing direct training to one MS student. How have the results been disseminated to communities of interest?A workshop was held with Gwinnett County officials, and a journal article was published. What do you plan to do during the next reporting period to accomplish the goals?I will be focusing on goal 1, with particular attention to agricultural water use.
Impacts
What was accomplished under these goals?
Under goal 2, I was able to assess public preferences for different attributes of local water quality policy.

Impacts
What was accomplished under these goals?
New projections of agricultural water withdrawals out to 2050 have been developed for the State of Georgia. These projections are used directly by the state's Regional Water Planning Councils to complete gap analyses and identify and develop solutions to potential water shortages in the future.These estimates were done at the county level and aggregated for each Water Planning Council. Initiated new analysis to compare the relative accuracy of water use estimates generated by econometric methods versus crop growth simulations. When exploring environmental policy options, sometimes neither the current state of the environmental good being analyzed nor the effectiveness of the proposed policy is known with certainty. This is the case with privately-owned, residential, onsite wastewater treatment systems (septic systems) â€" there is ample evidence that they can contribute to water quality impairment, but their contribution is generally stochastic in nature and the efficacy of technological solutions is uncertain. Furthermore, the benefits of ameliorating water quality impairments are public in nature. Septic system owners are legally responsible for maintaining their systems, but requiring them to upgrade otherwise properly functioning tanks is outside the scope of water quality regulations. An incentive structure is necessary to induce private homeowners to invest in septic upgrades that deliver both private benefits in addition to the positive externality for the wider public and environment. The question for policy makers is how these private incentives should be financed, and whether public support can be garnered. Results of a choice experiment in Gwinnett County, Georgia, accounting for both sources of uncertaintythe current state of water quality and the efficacy of the intervention in the design of water quality policy were generated. We find baseline water quality conditions and policy efficacy significantly affect public support for a policy transferring public funds to private homeowners, in terms of both sentiment and willingness to pay. The manner in which costs are shared across stakeholders also affects the selection of a policy option, but not willingness to pay for it.
