Water produced with coal-bed methane
Water Resources Division, U.S. Geological Survey
2000, Fact Sheet 156-00
Natural gas produced from coal beds (coal-bed methane, CBM) accounts for about 7.5 percent of the total natural gas production in the United States. Along with this gas, water is also brought to the surface. The amount of water produced from most CBM wells is relatively high compared to conventional...
Rapid recharge of parts of the high plains aquifer indicated by a reconnaissance study in Oklahoma, 1999
William J. Andrews, Noel I. Osborn, Richard R. Luckey

Occurrence of organochlorine pesticides in streambed sediment and fish from selected streams on the island of Oahu, Hawaii, 1998
Anne M. D. Brasher, Stephen S. Anthony
2000, Fact Sheet 140-00
Organochlorine pesticides were heavily used from the mid-1940s to the mid-1980s. The persistence of organochlorine pesticides, their tendency to accumulate in soil, sediment, and biota, and their harmful effects on wildlife brought this class of compounds into disfavor and eventually resulted in restriction or cancellation of most of them in...
