Nitrate contamination of groundwater is widespread and persistent in the shallow surficial aquifer of northwestern Whatcom County where dairy farming and forage production is a primary land-use activity. Application of dairy manure to cropland is intended to provide nutrients for crop growth and improve soil quality with the ideal goal to match the rate of nutrient application to that rate of nutrient removal by the crop. A study to test an alternate strategy for scheduling manure application to fields based on hydrologic properties of specific soils and fields, measurements of manure and soil parameters, and current and forecasted precipitation for the three days immediately following manure application is being...

The water resources in Tennessee are likely to be stressed in the future by factors such as population increase, urban and suburban development, climate change, and other competing demands. Water-resource managers and policy makers will need accurate water-use data for regional water-supply planning including infrastructure investment, conservation, and cost-recovery strategies. Quantifying public-supply and self-supplied industrial water use and relating the use to effects on -water resources and natural hydrologic systems; is important for the public and policy makers. This dataset includes public-supply water-use and self-supplied industrial water-use information for the State of Tennessee in 2010. Public supply...
