Abstract:In 2001 the US EPA lowered the maximum contaminant level for arsenic in drinking water from 50 ppb to 10 ppb. This change is expected to impact 10 percent of the nation's drinking water systems; the vast majority of those impacted are small, rural water suppliers. New approaches, particularly simple… more
Abstract:72679-Radioactively contaminated surfaces within Department of Energy and commercial nuclear facilities endanger workers and create problems with waste handling and disposal. Current methods for removing these radiological contaminants are expensive, use hazardous chemicals or dangerous rotating… more
Abstract:DESCRIPTION (provided by applicant): In 2001 the US EPA lowered the maximum contaminant level for arsenic in drinking water from 50 ppb to 10 ppb, based on studies indicating the lower limit would prevent a significant number of cancer deaths and other illnesses. The EPA estimates that there are… more
Abstract:72275-With the ever-present threat of terrorist attacks on American soil, it is increasingly important to monitor pre-nuclear-event warning signs and provide post-nuclear-event assessment for use in consequent management and emergency response. In particular, major urban centers are potential… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
