A water‐sampling apparatus used for the isolation and detection of Giardiacysts in water has been designed and tested. The sampling apparatus uses one of a variety of pumps or waterline pressure to move water through a filter. Two of the optional pumps are lightweight enough to make the apparatus portable and thus suitable for sampling in remote areas. This technique of sample processing produces

Water resources data for the 1985 water year for New Mexico consist of records of discharge and water quality of streams; stage, contents and water quality of lakes and reservoirs; and water levels and water quality in wells and springs. This report contains discharge records for 168 gaging stations; stage and contents for 25 lakes and reservoirs; water quality for 65 gaging stations and 179 wells

Water resources data for the 1985 water year for Iowa consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; ground-water levels and ground-water quality. This report contains discharge records for 111 stream-gaging stations; stage and contents for 8 lakes and reservoirs; water quality for 8 stream-gaging stations; sediment

Continuing studies are being made in west-central Kansas to provide up-to-date information that will aid in the management of groundwater for irrigation. The results are presented of the sixth in a series of studies that used a statistical technique called kriging, to produce hydrologic maps. The kriging technique interpolates water level altitudes at the center of each 1 sq mi section in the stud

The Cretaceous aquifer in southwest Minnesota consists of discontinuous, basal sandstone beds in the Dakota Formation and the overlying Codell Sandstone Member of the Carlile Shale of the Colorado Group. These sandstone beds are not laterally or vertically persistent throughout the area and generally are separated shale beds in the Dakota Formation and in the overlying Colorado Group of Cretaceous

The Red River-Winnipeg aquifer of Ordovician age occupies a depression in the Proterozoic crystalline bedrock of northwestern Minnesota. The Winnipeg Formation, which underlies the Red River Formation, consists of two units: A lower shaley mudstone and an upper medium-grained sandstone. The Red River Formation consists of a lower dolomitic, dark-gray limestone and upper, slightly less-dolomitic, l

The Edwards aquifer extends in a narrow belt from Bell County in the northeast to Kinney County in the southwest (index map) and provides water for at least nine counties in south-central Texas. Hydrologic boundaries divide the Edwards aquifer in the Austin area for which Barton Springs is the major discharge point. This part of the Edwards aquifer provides the municipal, industrial, domestic, and
