4 Acknowledgements The project sponsors thank the state and regional ground water monitoring staff who generously shared their time to respond to the surveys. Without their assistance, this information would not be available. Introduction Ground water is vital to public health, the environment, and the economy. Approximately 5% of community water systems rely on ground water. Nearly all of rural America, as well as large metropolitan areas, use ground water supplied water systems. Ground water feeds streams and rivers, especially during periods of drought or low flow. The agricultural industry uses ground water for irrigation. The percentage of total irrigation withdrawals from ground water increased from percent in 95 to percent in. According to a U.S. Government Accountability Office (GAO) report, 6 states anticipate water shortages statewide, regionally or locally in the next years under normal conditions. In the face of these expected shortages, the question is do states have programs that will monitor the ground water quantity and quality so they have information to take either proactive or reactive measures based on sound information? These surveys are intended, in part, to provide a broad overview of the current status of ground water monitoring being conducted by states and regional entities.

5 The Survey Between August and October, s went to state agencies in all 5 states targeting those agencies responsible for ground water quality and/or quantity regulations, and state geological surveys. The survey was sent simultaneously to different agencies in an effort to enlist a shotgun approach to ensure the highest number of respondents possible. The requested that they complete an electronic survey on statewide or regional ground water monitoring programs in their states. Regional was defined for purposes of the survey as monitoring networks that cover large, (e.g., multicounty) areas within a state. A separate survey was developed for ground water level monitoring programs and ground water quality monitoring programs. Forty-one states responded to the ground water level monitoring survey. Forty-nine states responded to the ground water quality monitoring survey. Although the surveys varied, the questions common to both surveys included: Program status Monitoring program objectives Who manages the program How is the program funded What types of wells are used in the network What are the numbers of wells sampled, the sampling frequency and the length of record Who collects the samples What metadata is collected Who developed the field practices standard operating procedures Who developed the data standards and data management standard operation procedures How are data stored The survey results were also supplemented by contacts and information provided by the U.S. Geological Survey. 5

17 Cell: B5 Comment: : The Kentucky Statewide Ambient Groundwater Monitoring Network is an "umbrella" title for integrating the various groundwater monitoring projects that we conduct. The network was established in 995 and along with sites we've monitored regularly since then, we've incorporated other projects into this system, including CWA Section 9 Nonpoint Source groundwater studies, monitoring conducted through an MOA with the Division of Pesticides, as well as monitoring/sampling conducted for complaints, assistance, and in response to environmental spills. Most, if not virtually all, of the data collected on these latter projects really represents ambient groundwater conditions. By design, Kentucky's groundwater monitoring is a dynamic and flexible system, rather than a static network of sites. Furthermore, and importantly, all groundwater monitoring activities conducted by various agencies throughout the state are coordinated, per legislation passed in 99, by the Interagency Technical Advisory Committee on Groundwater. This group of groundwater professionals from about a dozen entities with varying interests has proven to be an invaluable tool in our monitoring efforts.
