Decadal surface water quality trends under variable climate, land use, and hydrogeochemical setting in Iowa, USA Decadal surface water quality trends under variable climate, land use, and hydrogeochemical setting in Iowa, USA
Understanding how nitrogen fluxes respond to changes in agriculture and climate is important for improving water quality. In the midwestern United States, expansion of corn cropping for ethanol production led to increasing N application rates in the 2000s during a period of extreme variability of annual precipitation. To examine the effects of these changes, surface water quality was...

Streamflow characterization and summary of water-quality data collection during the Mississippi River flood, April through July 2011 Streamflow characterization and summary of water-quality data collection during the Mississippi River flood, April through July 2011
From April through July 2011, the U.S. Geological Survey collected surface-water samples from 69 water-quality stations and 3 flood-control structures in 4 major subbasins of the Mississippi River Basin to characterize the water quality during the 2011 Mississippi River flood. Most stations were sampled at least monthly for field parameters suspended sediment, nutrients, and selected...

Methods for estimating annual exceedance-probability discharges for streams in Iowa, based on data through water year 2010 Methods for estimating annual exceedance-probability discharges for streams in Iowa, based on data through water year 2010
A statewide study was performed to develop regional regression equations for estimating selected annual exceedance-probability statistics for ungaged stream sites in Iowa. The study area comprises streamgages located within Iowa and 50 miles beyond the State’s borders. Annual exceedance-probability estimates were computed for 518 streamgages by using the expected moments algorithm to fit...

Flood of August 11–16, 2010, in the South Skunk River Basin, central and southeast Iowa Flood of August 11–16, 2010, in the South Skunk River Basin, central and southeast Iowa
Severe thunderstorm activity during August 8–11, 2010 in central and southeast Iowa resulted in major flooding from August 11–16, 2010, in the South Skunk River Basin. Rain gages at Ames and Story City recorded 96-hour rainfall amounts of 9.61 and 8.70 inches, respectively. The majority of the rainfall occurred during a 52-hour period, beginning late at night on August 8. Within the...

Water-quality data for pharmaceuticals and other organic wastewater contaminants in ground water and in untreated drinking water sources in the United States, 2000-01 Water-quality data for pharmaceuticals and other organic wastewater contaminants in ground water and in untreated drinking water sources in the United States, 2000-01
This report presents water-quality data from two nationwide studies on the occurrence and distribution of organic wastewater contaminants. These data are part of the continuing effort of the U.S. Geological Survey Toxic Substances Hydrology Program to collect baseline information on the environmental occurrence of pharmaceuticals and other organic wastewater contaminants. In 2000...

A national reconnaissance of pharmaceuticals and other organic wastewater contaminants in the United States - I) Groundwater A national reconnaissance of pharmaceuticals and other organic wastewater contaminants in the United States - I) Groundwater
As part of the continuing effort to collect baseline information on the environmental occurrence of pharmaceuticals, and other organic wastewater contaminants (OWCs) in the Nation's water resources, water samples were collected from a network of 47 groundwater sites across 18 states in 2000. All samples collected were analyzed for 65 OWCs representing a wide variety of uses and origins...
