PDF Organic Compounds in Clackamas River Water Used for Public Supply near Portland, Oregon, 2003-05 [More info]
In all, 56 compounds were detected in samples collected approximately monthly during 2003-05 at the intake for the Clackamas River Water plant. On the basis of this screening-level assessment, adverse effects to human health are assumed to be negligible.
Organic Geochemistry Research Group in Kansas [More info]
The Organic Geochemistry Research Group of the Kansas District focuses on the fate and transport of organic contaminants in the environment with links to objectives, analytical methods, laboratory methods, publications, events, photos, and personnel.
PDF Organic compounds assessed in Neuse River water used for public supply near Smithfield, North Carolina, 2002-2005 [More info]
Reports concentration of organic compounds here, to serve as a baseline against which future measurements can be compared and to provide a general assessment of the quality of local water treatment efforts.
PDF Organic compounds in Elm Fork Trinity river water used for public supply near Carrollton, Texas, 2002-05 [More info]
We identified six compounds at concentrations less than human-health benchmarks, but within a factor of 10 of those limits. Those compounds might warrant further study to understand their transport and fate within the watershed.
PDF Organic compounds in Running Gutter Brook water used for public supply near Hatfield, Massachusetts, 2003-05 [More info]
The 258 organic compounds in this assessment are man-made: pesticides, solvents, gasoline hydrocarbons, personal-care and domestic-use products, pavement and combustion-derived compounds. None were found in concentrations deemed dangerous at this time.
Organic compounds in Truckee River water used for public supply near Reno, Nevada, 2002-05 [More info]
A preliminary indication of the potential importance of compounds detected in source water to the quality of finished water prior to distribution.
PDF Organic compounds in White River water used for public supply near Indianapolis, Indiana, 2002-05 [More info]
Measured concentrations of many compounds in water people use. Some compounds are regulated as health hazards; a few of these were over the benchmark limits. Others may become issues of concern, so studies such as this give us helpful background levels.
Parking-lot sealcoat: A major source of PAHs in urban and suburban environments [More info]
Explanation of chemical contaminants released into aquatic environments by popular sealcoating compounds used in parking lots, with frequently-asked questions, links, and contact information.
Pennsylvania fractured rock hydrology research [More info]
Links to reports for Pennsylvania on borehole geophysical studies, aquifer tests and properties, modeling, and hydrologic effects of an earthquake with links to MOC3D solute transport software package, program mission, and bibliography.
Pesticide National Synthesis Project: national assessment of pesticides in streams, rivers, and ground water of the United States [More info]
An assessment of pesticides in national water resources, with links to national reports, national statistics, national data, pesticide use, analytical strategy, and standards for the U.S.
