In the Field: Stormwater Treatment at a New Continental Airport Terminal   Water Engineering & Management March 2003
Airports potentially can generate enormous amounts of polluted stormwater runoff. In addition to hydrocarbons such as oil and fuel from cars, trucks and planes, winter weather brings added sand and salt to the roadways. Expanding the terminal area for Continental's new Global Gateway at Newark Liberty International Airport in late 2001 included increasing the paved areas around the terminal to accommodate the new taxiways and roadways. The system demonstrates the effectiveness of applying stormwater treatment technology to an already congested area where competition for space is fierce.

Arsenic Treatment Options for the Southwest   Water Quality Products February 2003   Arizona Water Quality Association
While high concentrations of arsenic are found mostly in the Western region of the United States, parts of the Midwest and New England show levels of arsenic that exceed the newly approved U.S. Environmental Protection Agency (EPA) standard of 10 parts per billion (ppb). Individuals not willing to wait for their water system's compliance with the arsenic standard currently are looking for treatment systems to use in their homes. POU and even point-of-entry (POE) treatment systems are an attractive solution for these individuals. The process should begin with a basic understanding of arsenic contamination and the element's chemistry, a complete water quality analysis of the application-specific water and the knowledge of available technologies.

Stormwater Treatment: A Look at Various Methods, Hydrodynamic Separators   Water & Wastes Digest July 2002
Since the passing of the Clean Water Act, the industry has made great strides in improving the quality of point source discharges to the environment. As treatment technologies continue to improve, non-point source pollution becomes a more significant contributor to environmental degradation.

Small Site Dictates Stormwater Treatment Solution in Mich. Redevelopment   Water & Wastes Digest July 2002
Ann Arbor, a densely populated university town of 180,000, has been seeing an increase in urban redevelopment pressure in recent years as developable land has become scarce and land values have risen. The city of Ann Arbor has worked closely with the County Drain Commissioner’s office to use this redevelopment as an opportunity to improve the quality of stormwater flowing into the county drains.

Stormwater Retrofitting to Protect Drinking Water Reservoirs from the Impacts of Urban Runoff - Part 1   Water Engineering & Management June 2002   James D. Benson, AICP, CPESC, and Melissa Beristain, CPESC
This paper summarizes the stormwater management element of the program and its control of the two key pollutants regulated by the SWTR: fecal coliform bacteria and turbidity that are conveyed to the reservoir by stormwater.
