Pesticide Trends in Major Rivers of the United States, 1992–2010

This report is part of a series of pesticide trend assessments led by the National Water-Quality Assessment Program of the U.S. Geological Survey. This assessment focuses on major rivers of various sizes throughout the United States that have large watersheds with a range of land uses, changes in pesticide use, changes in management practices, and natural influences typical of the regions being drained.

Environmental Contamination and Public Health: The Kilauea Story

In the last century, sugar plantations blanketed the Hawaiian Islands from Hilo to Lihue. Today, just a single plantation remains in operation. Yet many of these plantations leave behind a hidden legacy of contaminated soil from old pesticide mixing areas. The Hawai’I Department of Health (DOH) has tracked down many of these sites in remote areas, where there are few risks to the general public. Now, for the first time, DOH has discovered an old pesticide mixing site with alarmingly high levels of soil contamination persisting in the heart of a residential community. This article describes how the site was discovered and how government agencies have mobilized to clean it up and protect the public. Read More

Pesticides in Water and Suspended Sediment of the Alamo and New Rivers, Imperial Valley/Salton Sea Basin, California, 2006-2007

Water and suspended-sediment samples were collected at eight sites on the Alamo and New Rivers in the Imperial Valley/Salton Sea Basin of California and analyzed for both current-use and organochlorine pesticides by the U.S. Geological Survey. Samples were collected in the fall of 2006 and spring of 2007, corresponding to the seasons of greatest pesticide use in the basin. Large-volume water samples (up to 650 liters) were collected at each site and processed using a flow-through centrifuge to isolate suspended sediments. One-liter water samples were collected from the effluent of the centrifuge for the analysis of dissolved pesticides. Additional samples were collected for analysis of dissolved organic carbon and for suspended-sediment concentrations. Water samples were analyzed for a suite of 61 current-use and organochlorine pesticides using gas chromatography/mass spectrometry. A total of 25 pesticides were detected in the water samples, with seven pesticides detected in more than half of the samples. Dissolved concentrations of pesticides observed in this study ranged from below their respective method detection limits to 8,940 nanograms per liter (EPTC). The most frequently detected compounds in the water samples were chlorpyrifos, DCPA, EPTC, and trifluralin, which were observed in more than 75 percent of the samples. Read More

This website provides Nebraska’s System for Assessing Water Contamination Risk through the Nebraska Cooperative Extension. This is a series of publications and worksheets designed to help rural Nebraskans assess the contamination risk to groundwater from site structures or management practices and steps to take to reduce that risk. Individual publications guide the reader through a site evaluation, discussion of the relative risks and the ramifications of contamination, and provides numerous resources for additional information on specific issues.
