Anaerobic oxidation of [1,2-14C]dichloroethene under Mn(IV)-reducing conditions Anaerobic oxidation of [1,2-14C]dichloroethene under Mn(IV)-reducing conditions
Anaerobic oxidation of [1,2-14C]dichloroethene to14CO2 under Mn(IV)-reducing conditions was demonstrated. The results indicate that oxidative degradation of partially chlorinated solvents like dichloroethene can be significant even under anoxic conditions and demonstrate the potential importance of Mn(IV) reduction for remediation of chlorinated groundwater contaminants.

Factors influencing cattail abundance in the northern Everglades Factors influencing cattail abundance in the northern Everglades
Since the early 1900s, the Everglades have been influenced by anthropogenic actions including altered hydrology and increased nutrient loading. In the northern Everglades an apparent effect of these disturbances has been the development and proliferation of dense cattail (Typha spp. ) stands in areas previously dominated by sawgrass (Cladium jamaicense Crantz) and sloughs. Cattail cover...

Technical protocol for evaluating natural attenuation of chlorinated solvents in ground water Technical protocol for evaluating natural attenuation of chlorinated solvents in ground water
This Protocol is designed to evaluate the fate in ground water of chlorinated aliphatic hydrocarbons and/or fuel hydrocarbons. Documentation of natural attenuation requires detailed site characterization. The data collected under this protocol can be used to compare the relative effectiveness of other remedial options. and natural attenuation. This protocol should be used to evaluate...

Hydrogeology and water quality in the Cedar Rapids area, Iowa, 1992-96 Hydrogeology and water quality in the Cedar Rapids area, Iowa, 1992-96
The U.S. Geological Survey (USGS) and the city of Cedar Rapids conducted a cooperative study from 1992 to 1996 to assess the hydrogeology and water quality in the Cedar River, Cedar River alluvial aquifer, Devonian aquifer, and Silurian aquifer in a 231-square-mile area of Benton and Linn Counties near Cedar Rapids, Iowa. The city of Cedar Rapids withdrew an average of 34 million gallons...

Ground-water conditions in Georgia, 1997 Ground-water conditions in Georgia, 1997
Ground-water conditions in Georgia during 1997 and for the period of record were evaluated using data from ground-water-level and ground-water-quality monitoring networks. Data for 1997 included in this report are from continuous water-level records from 71 wells and chloride analyses from 14 wells. In 1997, annual mean ground-water levels in Georgia ranged from 6.2 feet (ft) lower to 5...
