FY2010 Challenge Areas

The Office of Groundwater and Regional review teams evaluated proposals for three "challenge areas" in groundwater availability:

1. estimating groundwater use for principal aquifers,
2. monitoring the effects of climate change on groundwater resources, and
3. assessment of saline groundwater resources.

The response and quality of proposals was excellent. The projects selected for funding are listed below.

Water Use

• Consumptive water use and groundwater withdrawals in irrigated lands (WA) [190KB PDF]
• Estimating groundwater withdrawals for the Floridan and Biscayne aquifers (FL) [110KB PDF]
• Evaluation of U.S. domestic per capita water-use coefficients (KS) [95KB PDF]
• Estimating groundwater withdrawals and consumptive use for principal aquifers (CA) [390KB PDF]

Climate

• Quantifying effects of climate change on the snowmelt-dominated groundwater resources of northern New England (ME, NH, VT) [250KB PDF]
• Monitoring effects of climate change on groundwater recharge through remote sensing of seasonally frozen ground (WA) [95KB PDF]
• Statistical toolkit for climate analysis of hydrologic time series (AZ) [515KB PDF]
• Fens as indicators of changes in groundwater recharge (CA) [40KB PDF]

Saline Groundwater

• Saline water aquifer mapping project in the Southeastern United States (GA) [190KB PDF]
• Development of salinity concentration maps using geochemical, geophysical, and geostatistical methods in the Cretaceous aquifer system (AR) [435KB PDF]
• Locating and assessing saline groundwater resources in the southern midcontinent (OK) [460KB PDF]
