VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 22, 2008) - Nanika Resources Inc. (TSX VENTURE:NKA)(FRANKFURT:C7X) (the "Company") or "Nanika") announces that work has been progressing steadily with environmental baseline and engineering studies required for the development of Nanika's Molybdenum Project located approximately 85 kilometers southwest of Houston, British Columbia. Korean Negotiations Update: In addition to the technical update that follows below Nanika is pleased to update on...
By Erik Robinson, The Columbian, Vancouver, Wash. Jul. 9--Critics of a new Columbia River crossing have long argued that a planned replacement bridge on Interstate 5 will degrade the environment and fuel more urban sprawl. Now, federal environmental regulators are echoing many of those same concerns -- plus a new one. The Environmental Protection Agency called for project officials to assure that bridge footings drilled deep into the river bottom won't pollute Clark County's major...
By Stephen Speckman Deseret News The Southern Nevada Water Authority has filed a request to deny "interested person status" to 15 applicants, including several from Utah, who want a say in a proposal to pipe water from sources near the Utah/Nevada border to Las Vegas. "We oppose the pipeline," said Steve Erickson on behalf of the Great Basin Water Network. "We think there are other alternatives they should explore." The Water Authority told Tracy Taylor, the Nevada state engineer, in its...
By Ramachandran, Mahesh On a flat floodplain, on the northwestern coast of the island of Java, modern office towers dominate the Jakarta skyline, lending the city an aura of strength and prosperity. But, like many large urban areas in the developing world, the majority of residents of Indonesia's capital lack a reliable water supply from the city's public water system, which comes largely from surface water sources. As a result, many depend on groundwater, and because civic authorities have...
By Kayla Bunge, The Janesville Gazette, Wis. Jun. 14--WILLIAMS BAY -- The development of a computer model to map groundwater flow in the Geneva Lake area is about six months behind. "At what point in time does the continued progress of this area pass a tipping point?" asked Jim Celano, executive director of the Geneva Lake Conservancy. "When do we poke too many holes in the ground?" Madeline Gotkowitz, of the Wisconsin Geological and Natural History Survey, said the study "just isn't there...
By Singha, Kamini ABSTRACT The concepts of total stress, effective stress, and fluid pressure are important to understanding where water comes from when producing water from a confined aquifer system. However, the overall conceptual image of pumping confined aquifers is difficult for many students to grasp, because pore space is not drained, but rather water is produced as a function of the water and aquifer compressibilities. I present a simple, inexpensive demonstration, which can be used...
By Rotzoll, Kolja; El-Kadi, Aly I; Gingerich, Stephen B ABSTRACT: In recent years the ground-water demand of the population of the island of Maui, Hawaii, has significantly increased. To ensure prudent management of the ground-water resources, an improved understanding of ground-water flow systems is needed. At present, large-scale estimations of aquifer properties are lacking for Maui. Seven analytical methods using constant-rate and variable-rate withdrawals for single wells provide an...
By Maliva, Robert G; Guo, Weixing; Missimer, Thomas M ABSTRACT: Aquifer storage and recovery (ASR) is part of the solution to the global problem of managing water resources to meet existing and future freshwater demands. However, the metaphoric "ASR bubble" has been burst with the realization that ASR systems are more physically and chemically complex than the general conceptualization. Aquifer heterogeneity and fluid-rock interactions can greatly affect ASR system performance. The results...
