Revisiting the Selection of Stainless Steel in Water and Wastewater Treatment Environments: Part 3   Water Engineering & Management July 2002   Frederick Bloetscher, Richard J. Bullock, Robert E. Fergen, Gerhardt M. Witt, and Gary D. Fries
Based on the City of Hollywood’s experience, the use of 316L stainless steel should be evaluated carefully due to the potential for problems in the erection and construction of water treatment facilities that will be in contact with high chloride water and/or other corrosive chemistries. As with many membrane facilities, much of the stainless steel is exposed (not buried), which subjected it to atmospheric as well as water quality problems. Therefore, unless the quality control of the raw and reject water (chemical, physical and microbial) can be assured, 316L stainless steel may not be the appropriate material for engineers to specify.

Revisiting the Selection of Stainless Steel in Water and Wastewater Treatment Environments: Part 2   Water Engineering & Management June 2002   Frederick Bloetscher, Richard Bullock, Robert Fergen, Gerhardt Witt, & Gary Fries
Aerobic bacteria (Crenothrix, Gallionella) primarily are encountered in the fresh surface waters, although anaerobic sulfate-reducing bacteria and facultative strains also are encountered. Ground waters are more likely to contain anaerobic and facultative bacteria, as well as Gallionella than surface waters.3 Sulfate-reducing bacteria also are found in seawater.3

Manzanar   Water Engineering & Management February 2002   Mike Harrington
Two months after the bombing of Pearl Harbor (December 7, 1941), President Franklin D. Roosevelt signed Executive Order number 9066, calling for the relocation of Japanese American citizens and aliens. The order authorized the secretary of war to exclude citizens and aliens of Japanese descent from the West Coast as a security measure against sabotage and espionage. This order empowered the round-up of 70,000 U.S. citizens of Japanese descent and 42,000 resident aliens.

Pumping System Helps Town Bring New Development Up to Code   Water Engineering & Management November 2001
When a Leicester, Mass., developer planned a subdivision of 16 houses at the same elevation as the town’s water tower, he was faced with the problem of how to provide minimum water pressure mandated by the state. He had read about the use of a Goulds Aquavar pump control system in high-rise commercial buildings, and the idea of a variable-speed system appealed to him. He thought a pressure-demand system might do the job cost effectively.

Data Acquisition, Legacy Systems and Your Intranet   Water & Wastes Digest February 2001   By Fred Noble
There are lots of parallels between the events of November 2000 and the events that take place in any factory or municipality that runs a process or monitors its effluent. The technology exists to achieve the much-talked-about six sigma (3.4 errors per million events) levels of measurement quality or process integrity. But antiquated legacy systems keep getting in the way. And, as is the case on the American political scene, it just is not that easy to replace those old methods of measuring things.
