Pesticides in the atmosphere of the Mississippi River Valley, part II: Air Pesticides in the atmosphere of the Mississippi River Valley, part II: Air
Weekly composite air samples were collected from early April through to mid-September 1995 at three paired urban and agricultural sites along the Mississippi River region of the Midwestern United States. The paired sampling sites were located in Mississippi, Iowa, and Minnesota. A background site, removed from dense urban and agricultural areas, was located on the shore of Lake Superior...

Rice pesticide concentrations in the Colusa Basin Drain and the Sacramento River, California, 1990-1993 Rice pesticide concentrations in the Colusa Basin Drain and the Sacramento River, California, 1990-1993
The pesticides molinate, thiobencarb, and carbofuran are applied to rice (Oryza sativa L.) fields in the Sacramento Valley, California, each year during April through June. These pesticides are of concern because of their adverse effects on water quality and their potential adverse effects on aquatic life. Therefore, the California Regional Water Quality Control Board (CRWQCB) mandated...

Metals transport in the Sacramento River, California, 1996-1997; Volume 2: Interpretation of metal loads Metals transport in the Sacramento River, California, 1996-1997; Volume 2: Interpretation of metal loads
Metals transport in the Sacramento River, northern California, from July 1996 to June 1997 was evaluated in terms of metal loads from samples of water and suspended colloids that were collected on up to six occasions at 13 sites in the Sacramento River Basin. Four of the sampling periods (July, September, and November 1996; and May-June 1997) took place during relatively low-flow...
Aquifer-system compaction and land subsidence: Measurements, analyses, and simulations – The Holly Site, Edwards Air Force Base, Antelope Valley, California Aquifer-system compaction and land subsidence: Measurements, analyses, and simulations – The Holly Site, Edwards Air Force Base, Antelope Valley, California
Land subsidence resulting from ground-water-level declines has long been recognized as a problem in Antelope Valley, California. At Edwards Air Force Base (EAFB), ground-water extractions have caused more than 150 feet of water-level decline, resulting in nearly 4 feet of subsidence. Differential land subsidence has caused sinklike depressions and earth fissures and has accelerated...

Distributions of uronic acids and O-methyl sugars in sinking and sedimentary particles in two coastal marine environments Distributions of uronic acids and O-methyl sugars in sinking and sedimentary particles in two coastal marine environments
Although recent research has indicated that bacteria may contribute an important fraction of biochemical residues in terrestrial and marine environments, it is difficult for geochemists to identify contributions from these ubiquitous and biochemically diverse organisms. Previous studies have suggested uronic acids and O-methyl sugars may be useful indicators of microbial abundance and...

Occurrence and transport of total mercury and methyl mercury in the Sacramento River Basin, California Occurrence and transport of total mercury and methyl mercury in the Sacramento River Basin, California
Mercury poses a water-quality problem for California's Sacramento River, a large river with a mean annual discharge of over 650 m3/s. This river discharges into the San Francisco Bay, and numerous fish species of the bay and river contain mercury levels high enough to affect human health if consumed. Two possible sources of mercury are the mercury mines in the Coast Ranges and the gold...

Negative pH, efflorescent mineralogy, and consequences for environmental restoration at the iron mountain superfund site, California Negative pH, efflorescent mineralogy, and consequences for environmental restoration at the iron mountain superfund site, California
The Richmond Mine of the Iron Mountain copper deposit contains some of the most acid mine waters ever reported. Values of pH have been measured as low as -3.6, combined metal concentrations as high as 200 g/liter, and sulfate concentrations as high as 760 g/liter. Copious quantities of soluble metal sulfate salts such as melanterite, chalcanthite, coquimbite, rhomboclase, voltaite...

Transport of diazinon in the San Joaquin River Basin, California Transport of diazinon in the San Joaquin River Basin, California
ABSTRACT: Most of the application of the organophosphate insecticide diazinon in the San Joaquin River Basin occurs in winter to control wood-boring insects in dormant almond orchards. A federalstate collaborative study found that diazinon accounted for most of the observed toxicity of San Joaquin River water in February 1993. Previous studies focused mainly on west-side inputs to the...
