Let Your UV Light Shine

September 1, 2003

Research scientists overcome drinking water industry assumptions that UV radiation is ineffective for fighting Cryptosporidium and develop a UV treatment to battle the potentially deadly pathogen

The enormity of the problem facing the drinking water industry first surfaced in the United States in 1993, when Cryptosporidium, a single-celled parasite living in the intestines of warm-blooded animals, made its way into the drinking water in Milwaukee, leaving 403,000 people sick and 104 people dead.

Training -- The Big Picture

September 1, 2003By Christopher Morrissey

Implementing training programs as part of the whole solution can help improve plant efficiency, especially with the help of a few new technological advances in training

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.

A New Weapon in the Fight for Clean Water

Recent studies show that activated carbon can effectively reduce bromate in drinking water

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.

Bridging the Gap

Polymeric surfactant technology bridges the gap between oil water separator capability and the parameters that must be met for regulatory compliance and industrial closed-loop processing

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.

Using onsite, submerged aerobic fixed film bioreactors to treat sanitary wastewater

Any company, land developer or individual who has attempted residential or commercial development in a rural suburban area is no stranger to the following scenario: "50 plus acres with good road frontage, high traffic count, public water and gas, but no sewer."

On the Alert

Biosensors are being used as early warning systems to detect chemical contaminants in drinking water

Drinking water professionals know that the quality of raw or finished water supplies may be adversely impacted by a number of contaminants, including petroleum products from leaking tanks or pipelines, insecticides and herbicides from agricultural runoff, pathogens from untreated sewage discharges and others.

Saving Groundwater from Stubborn Pollutants

Spray aeration vapor extraction systems and other innovative technologies are successfully treating recalcitrant compounds

Groundwater contamination has been an area of environmental concern for decades. Underground storage tank and process line leaks, product spills and intentional dumping have been the greatest contributors to the problem.

Can We Be MTBE Free?

May 1, 2003By Aaron Jensen

For years studies have shown the dangers of this once popular gasoline additive; now some in California and other parts of the nation might be taking the warnings to heart

Methyl Tertiary Butyl Ether (MTBE) is a gasoline additive used to oxygenate and add octane to gasoline. Since the late 1970s, lead has been banned from use in automobile fuel use due to its toxicity to humans, leading to the problem of low oxygenation in gasoline that has caused exhaust to be more easily trapped in urban airsheds.

Disinfection and monitoring can be used as measures to protect drinking water plants against terrorism

Public drinking water plants seeking to guard against the threat of terrorist attacks might do well to review and enhance some of the technology they already have on site.

Why not Water?

The Association of Metropolitan Sewerage Agencies and the Water Infrastructure Network foresee a grim future, unless the federal government commits to developing a long-term, sustainable funding source for core water and wastewater infrastructure

More than 30 years have passed since the enactment of the Clean Water Act in 1972. In honor of the Act's 30th anniversary, President George W. Bush dubbed 2003 the "Year of Clean Water." Organizations and individuals involved in clean water issues have rightly employed this occasion to trumpet the progress the United States has made in water quality over the past few decades.

A Helping Hand from the West

To improve Asia's water and wastewater environment, the United States-Asia Environmental Partnership promotes the transfer of U.S. technology

While Asia's public and private sector stakeholders strive to achieve robust economic growth, they are faced with the daunting task of mitigating the effects of that growth on the environment and addressing a wide range of legacy environmental problems, particularly in the areas of water and wastewater management.
