Operational Procedures for Collecting Water-Quality Samples at Monitoring Sites on Maple Creek Near Nickerson and the Platte River at Louisville, Eastern Nebraska

Johnson, Steven M.; Swanson, Robert B.

Abstract:

Prototype stream-monitoring sites were operated during part of 1992 in the Central Nebraska Basins (CNBR) and three other study areas of the National Water-Quality Assessment (NAWQ) Program of the U.S. Geological Survey. Results from the prototype project provide information needed to operate a net- work of intensive fixed station stream-monitoring sites. This report evaluates operating procedures for two NAWQA prototype sites at Maple Creek near Nickerson and the Platte River at Louisville, eastern Nebraska. Each site was sampled intensively in the spring and late summer 1992, with less intensive sampling in midsummer. In addition, multiple samples were collected during two high- flow periods at the Maple Creek site--one early and the other late in the growing season. Water-samples analyses included determination of pesticides, nutrients, major ions, suspended sediment, and measurements of physical properties. Equipment and protocols for the water-quality sampling procedures were evaluated. Operation of the prototype stream- monitoring sites included development and comparison of onsite and laboratory sample-processing proce- dures. Onsite processing was labor intensive but allowed for immediate preservation of all sampled constituents. Laboratory processing required less field labor and decreased the risk of contamination, but allowed for no immediate preservation of the samples.
