Features

Levee Leader

By Robert L. Reid

After the levees broke in 2005 and flooded more than 80 percent of New Orleans, Louisiana’s governor and legislature moved to replace the state’s fragmented, politicized system of local levee oversight with a regional approach that for the first time would make flood control experts responsible for maintaining the Crescent City’s hurricane protection system. Thomas L. Jackson, p.e., d.wre, f.asce, a former asce president, has taken charge of the larger of these two “super levee boards,” the Southeast Louisiana Flood Protection Authority–East.

SPECIAL SECTION: The Arsenic Crisis

Millions of people in developing nations and rural communities are being poisoned by high levels of arsenic in their drinking water. They suffer afflictions ranging from skin lesions to cancer, and in some cases premature death results. For these populations, the treatment solutions need to rely on local materials and supplies, and they must be simple to construct and easy to maintain. This special section focuses on two such solutions.

Clean Drinking Water for All

By Richard Fahey, P.E., BCEE

A method for filtering arsenic from water developed by the Bengal Engineering and Science University, Shibpur, employs pelletized granules of activated alumina housed in 30 cm diameter canisters that can be attached to existing hand pumps.

Removing Arsenic Sustainably

By Jeremiah D. Jackson, Ph.D., P.E., M.ASCE

A home-tested method for removing arsenic naturally uses an easily created pond with artificial channels that enable the water to meander through a planting of indigenous aquatic macrophytes—namely, cattails. Local species of fish in the pond can control mosquitoes.

Proud Witness

By Jerome Rasgus, S.E., M.ASCE, John Dennington, P.E., RA, Larry Memberg, P.E., A.M.ASCE, and Ann Rae Jonas

Inspired by Joe Rosenthal’s famous Associated Press photograph of the flag raising on Iwo Jima, the most dramatic portion of the new National Museum of the Marine Corps, in Quantico, Virginia, is a 230 ft (70 m) long mast that rises from the floor of the circular main gallery. Clad in stainless steel, the mast is a slender cantilever member supported by rib and ridge beams.
