Summarizes information on the water resources of Lafayette Parish, Louisiana. Information on groundwater and surface-water availability, quality, development, use, and trends is based on previously published reports.
In 2005, about 29.2 million gallons per day (Mgal/d) of water were withdrawn here, including about 26.8 Mgal/d from groundwater sources and 2.45 Mgal/d from surface-water sources. Rice irrigation accounted for 74 percent (21.7 Mgal/d) of the total.
In 2005, about 15.8 million gallons per day (Mgal/d) of water were withdrawn, including 4.12 Mgal/d from groundwater and about 11.7 Mgal/d from surface-water sources.Public supply use accounted for about 78 percent (12.4 Mgal/d) of the total water withdra
In 2005, about 6.67 million gallons per day (Mgal/d) of water were withdrawn here, including about 6.46 Mgal/d from groundwater sources and 0.21 Mgal/d from surface-water sources. Public-supply use accounted for about 76 percent (5.06 Mgal/d) of the total
Overview of a project in Virginia to develop a program for assessing public supply source waters to determine their susceptibility to contamination and to determine which systems need detailed source-water assessments.
Description of project to study the distribution of saline water in the aquifers of the Coastal Plain of Virginia and the potential for saline water intrusion by evaluating chloride concentrations and the factors affecting chloride distribution.
In 2005, about 9.52 million gallons per day (Mgal/d) of water were withdrawn, including about 9.33 Mgal/d from groundwater and 0.19 Mgal/d from surface-water. Public supply use accounted for 70% of the total.
Explains the strategy that USGS will use to estimate the distribution and abundance of freshwater resources, evaluate factors affecting availability, estimate undeveloped potential resources, and forecasting likely changes due to other factors.
