When the Oneida Indian Nation was expanding its operations from a small bingo/casino facility to a full resort complex, it began professionally designing new nine-hole and 18-hole golf courses. The two courses were initially designed to include both groundwater and public water systems to support their irrigation needs.

Traditionally, training has often been approached as an afterthought -- a vendor demonstrating a specific product to operators after the product has been purchased and installed. But in today's highly competitive marketplace, training is an important part of the whole solution. Training provides operators with tools and insights that can help them lower costs and improve efficiency plant wide.

Implementation of a new Laboratory Information Management System (LIMS) has helped the Portland, Ore., Bureau of Water Works meet regulatory requirements while increasing laboratory throughput. Water quality laboratories across the country face the need to perform a higher volume of testing and improve data security in order to ensure the safety of the nation's water supply.

All drinking water treatment plants (WTPs) must dispose of their potable water residuals. One privately owned water utility in Fairbanks, Alaska, uses a filter press to dewater its water treatment mineral byproducts. By doing so, the utility achieves zero discharge to the nearby Chena River, which serves as a recreational area and spawning ground for several fish species threatened with possible extinction.

Activated carbon is well known for its ability to remove organic compounds from water through a process known as adsorption, remove chlorine and chloramine through various chemical reactions and serve as a general filter media; however, its use for reduction of bromate is unclear.

Water conservation and prevention of water pollution have become global issues affecting the life and health of people and the ecosystems they inhabit. The ability of ecosystems to recover has been stretched to the limit by overpopulation. As population reduction is unlikely and in fact the obverse is anticipated minimization of environmental impact is critical for the survival of the human species.

Isn't the number of remedial technologies that actually exist to remediate and protect groundwater amazing? Not only does industry have a wide selection of pump and treat options, there is a full array of in-situ technologies that engineers continue to conceive and refine.

Membrane bioreactor (MBR) has emerged as the wastewater treatment technology of choice for an increasing number of municipalities over the last five years. This growth is driven by the very high quality effluent produced by MBR -- exceeding strict standards or ideal for direct reuse -- and is fuelled by a steady reduction in treatment cost resulting from improvements in membrane productivity.

Virtually all industrial activities generate some amount of wastewater. Disposal of this water in an environmentally responsible way has been a legal requirement since the passage of the Clean Water Act in 1972.

Louisiana contains approximately 40 percent of the coastal wetlands in the United States. These wetlands consist of swamps and both economically and environmentally important freshwater and saltwater marshes. The wetlands support nearly a third of the fish and shellfish yields in the lower 48 states and approximately 40 percent of its fur harvest, while there are more than 200,000 acres of private oyster leases. Also, the wetlands provide a wintering habitat for more than half of the ducks and geese in the Central and Mississippi Flyways.

The most commonly used methods for water treatment have been around for more than a century and rely on large basins to accommodate the processes of sedimentation, sand filtration and the addition of chemicals. These methods often do not address the current pressures placed on water resources, falling short of stringent new drinking water regulations.
