Together, these systems were insufficient for near-term demand and they fell far short of the projected future needs for this fast-growing community.
Assessing Leakage in Water Supply Networks Using Flowmeters
Water Engineering & Management
March 2003
Richard Furness, PhD., CEng. and ISA Fellow
Flowmeter usage is diverse and central to the entire water cycle control within the industry. The metering process directly or indirectly influences resource management, process control, new works planning, distribution management, leakage detection, financial control and environmental issues.

New Test Technique Measures Light to Gauge Toxicity
Water & Wastes Digest
January 2002
Security measures do exist to safeguard our public water supply. Utilities routinely employ techniques such as chlorination, filtration, and ultraviolet treatment, to name a few. However, given the changes that have taken place in the world since September 11, 2001, the prospect for intentional contamination seems more possible than ever before. We want to have confidence that our existing security measures and analytics are adequate but with so many possibilities, how can we?
Biofouling in Raw Water Supply Wells and Its Impact
Water Engineering & Management
October 2001
Frederick Bloetscher, P.E., Gerhardt M. Witt, P.G. and Robert E. Fergan, P.E.
As membrane systems become more prominent in the treatment of well water supplies, more care must be taken to review the effects of microbiological contamination.

Desalination System Brings Water to Small Island Off Washington Coast
Water & Wastes Digest
February 2000
Off the coast of Washington, 32 families on Guemes Island were faced with an aging well that was drawing salt water into its system. Because groundwater is scarce on the island, residents had to rely on what little rain water soaks into the ground.
Plunging into Protection

Highland Tank, one of the founders of the Steel Tank Institute and a leading producer of underground protected steel storage tanks, has developed a new innovation in protective coating technology.
Filter Media Rids Iron from Groundwater
Water Engineering & Management
December 1997
Yun H. Zhang
The most common process for iron removal from water is to allow water-soluble ferrous iron (FE2+) in water to turn into water-insoluble ferric iron (Fe3+), and then capture FeIII (iron oxide) particles by filtration.
Recovering the Costs of Water-Supply Cleanup
Water Engineering & Management
September 1997
David Terry
Recovering contaminants caused by industry from public water-supply wells can be expensive, but there are ways water suppliers can recoup all or part of these costs.
Understanding and Solving Fracture Flow Problems
Water Engineering & Management
September 1997
Dr. Thomas Doe
This article compares fracture flow with flow in more conventional porous systems and suggests solutions to fracture flow problems.
How to Select the Right Groundwater Sampler
Water & Wastes Digest
September 1997
Before selecting a sampler, all of the particulars in the project must be considered to determine which pump is most suitable. In some applications, custom units may be designed for specialized uses.
Drink the Water: Proven Methods, New Advances in Ground Water Treatment
Water & Wastes Digest
March 1997
Robert W. Masters
Ground water is the most popular source for water in the United States. Now with growth of proven treatment methods and advances in treatment technologies for contaminated ground water, the future is bright for the ground water industry.
Blasting Alternative Removes Lead Paint, Renders Waste Non-hazardous
Water & Wastes Digest
January 1997
Some contractors and structure owners interested in safely removing lead paint are considering an alternative method. A blasting additive can be used with any non-recyclable abrasive to render lead or other heavy metal waste non-hazardous.
Optimizing Water Well Productivity and Operating Costs
Water Engineering & Management
May 1996
Tom Sheahan and Joe Minneci
Deciding whether to repair or replace wells and when are important decisions utilities must make for every well in their system. A cost-analysis methodology has been developed to help in these decisions.
