Between February 1996 and November 2000, geophysical logging was conducted in 27 open borehole wells in and adjacent to the Butz Landfill Superfund Site, Jackson Township, Monroe County, Pa., to determine casing depth and depths of water-producing zones, water-receiving zones, and zones of vertical borehole flow. The wells range in depth from 57 to 319 feet below land surface. The...

The iron industry played a vital role in the industrialization of the United States and in the development of the U.S. economy and society. Much of the early history of the iron industry took place in Virginia. The remains of 11 iron furnaces and nearby mines in the George Washington and Jefferson National Forests in Virginia and West Virginia are silent reminders of a time when iron...

Water-resources data for the 2000 water year for New Hampshire and Vermont consists of stage, discharge, and water quality of streams; contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 76 gaging stations, stage records for 5 lakes, monthend contents for 2 lakes and reservoirs, water levels for 28 observation wells. Also included are...

Water-resources data for the 2000 water year for Ohio consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report, in two volumes, contains records for water discharge at 122 gaging stations and 65 partial-record sites; water levels at 65 observation wells and 23...

Water from 265 domestic wells that tap the unconfined Kirkwood-Cohansey aquifer system in the Coastal Plain of New Jersey contained concentrations of mercury that are equal to or exceed the U.S. Environmental Protection Agency maximum contaminant level (MCL) of 2 ug/L (micrograms per liter). The wells range in depth from 50 to 200 feet, and are located in 32 discrete, mostly residential...

Densely populated communities surround many of the larger lakes in northwestern New Jersey. These communities derive most of their water supply from wells. The lakes can be navigated by gasoline-powered watercraft, can be in various stages of eutrophication, may contain pathogens associated with bathing and waterfowl, and are periodically subjected to chemical applications to control...

In vitro studies indicated that commercially prepared transport systems containing Amies, Stuart's, and Cary–Blair media worked equally well in sustaining the viability of the fish pathogen Aeromonas salmonicida, which causes furunculosis. The bacterium remained viable without significant increase or decrease in cell numbers for as long as 48 h of incubation at 18–20°C in Stuart's...

The U.S. Fish and Wildlife Service federal protocol for dual disinfection of fish eggs in 50 mg/L iodine solution for 30 min followed by a secondary disinfection in 100 mg/L iodine for 10 min was investigated during six spawning cycles of Atlantic salmon Salmo salar held at the Richard Cronin National Salmon Station (Sunderland, Massachusetts). This population of salmon had undergone an...

Wildlife research conducted by scientists at the Leetown Science Center helps client bureaus to better manage federal lands and trust species by making objective, science-based decisions.

The Leetown Science Center’s research provides information on early detection and assessment, ecological effects and new methods of control of invasive species.

Seawater and natural brines accounted for about 63% of US magnesium compounds production during 2000. Premier Services in Florida, Dow Chemical in Michigan, Martin Marietta Magnesia Specialties, and Rohm & Haas recovered dead-burned and caustic-calcined magnesias from seawater. And Premier Services' recoveries, in Nevada, were from magnasite.
