Plugging the Leak . . .in Water Security
Water & Wastes Digest
January 2004
William G. Sewell and John F. Shawcross
Whether the utility serves 5,000 people or 500,000 people, a facility that is easy to attack is an attractive, tempting target. Such water utilities must remove the metaphorical bull's-eye tattooed on their facilities by taking swift, certain, prudent action.
'Out of the Box'

Carla Fisher and Gregory C. Gilles, AdEdge Technologies
Emerging commercial technologies are replacing the "old standards" for small water system (SWS) applications. In contrast to large community systems, competitive economics, simple operation and low waste production will drive changes in technology and engineering. Some out-of-the-box thinking will be necessary in the shift to provide simpler, packaged or preengineered arsenic treatment systems.

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.

Water Engineering & Management
October 2002
Dennis F. Hallahan P.E.
In 1997, EPA and Congress officially recognized onsite wastewater treatment systems (commonly referred to as septic systems) as a viable, long-term solution for treating wastewater. This was an important designation since nearly 40 percent of new homes in the United States use this type of system to treat household wastewater.
