The U.S. Geological Survey's (USGS) mission is to provide reliable scientific
information about the Nation's natural resources. An integral part of that mission
is to provide consistent, long-term water-resources data to customers, cooperators,
and the public. To accomplish our mission, we operate a widespread surface and
ground-water data collection network as well as research a wide range of scientific
issues throughout Iowa.

The deleterious effects (for example, alteration of fish behavior, etc.) observed in this study confirm that effluents containing pharmaceuticals can adversely affect fish in ways that are central to sustaining populations. A summary of the results can be obtained here.
New scientific research from the U.S. Geological Survey details how landfill leachate, disposed from landfills to environmental pathways, is host to numerous contaminants of emerging concern. A summarization of this study and links to more information can be found here
A method of using computer streamflow models for nine eastern Iowa streams to estimate streamflow at any location in the stream network.
A new interactive mapping tool provides predicted concentrations for 108 pesticides in streams and rivers across the Nation and identifies which streams are most likely to exceed water-quality guidelines for human health or aquatic life.
Statistical tools and rainfall-runoff methods are evaluated for estimating historical daily streamflow for ungaged watersheds in the Des Moines and Iowa River Basins.
This study represents the first national-scale study of the presence of neonicotinoids in urban and agricultural land use settings across the Nation and was
completed as part of ongoing USGS investigations of pesticide levels in streams. A summer of this study and links to more information can be found at:
The Virginia Commonwealth University, USGS, Westat, and the National Cancer Institute have collaborated to develop a model for predicting nitrate concentrations in private wells in Iowa.
The Iowa Department of Natural Resources, the U.S. Geological Survey, the U.S. Department of Agriculture, the State Hygienic Laboratory, and the Center for Health Effects of Environmental Contamination collaborated on the first ever comprehensive study of contaminants of emerging concern in Iowa's groundwater.
The U.S. Geological Survey and the U.S. Environmental Protection Agency are collaborating on a field-based study of chemical mixture composition and environmental effects in stream waters affected by a wide range of human activities and contaminant sources.
More information and report can be found here.
New USGS comparison study identifies best flood-frequency estimation methods for small drainage basins in Iowa. Comparisons included 80 streamgages and 5 different flood-estimation methods.
