On The Cover
your water system on shaky ground?
An earthquake is one of the most destructive things that can happen to a
community. But, there are several things that can be done to reduce the
effects of an earthquake and to lessen the damage to your water system.
This article by On Tap editor Mark Kemp-Rye describes what happens in an
earthquake and goes on to provide real-life examples of seismic water system
design and emergency planning.
Making it Through a Dry Spell
Drought can blister any area it touches, but there are ways to prepare
for it. This article by On Tap editor Kathy Jesperson discusses
drought's impacts and provides a 10-step mitigation plan prepared
by the National Drought Mitigation Center.
Before and After the Rising Water
Floods are the most common natural disaster worldwide, and cleanup
and recovery can be dangerous. If your system is in a flood area,
you can prepare for the worst. This article discusses how to prepare
for a flood and be ready for the inevitable.
Deadline on the Horizon: States Progress Well with Source Water Assessments
The Source Water Assessment Program is well under way in states around
the country. Identifying potential contamination in a drinking water
system's source must be completed in most states by 2003. Read about
the program and how states are working toward their deadline.
Project Brings Water to Remote Villiage
Living in a country that is accustomed to turning on a tap to get
safe drinking water can sometimes make us forget that many people
don't have that luxury. This article, written by former Peace Corps
volunteer Edward Winant, Ph.D., tells the story of Sokamalam, a
small village in Cameroon, and the work its people did to get water
to the village
By June 2003, all government entities with less than $10 million
in revenues must adopt a new accounting standard known as "GASB
34." Pat Taylor and Linda Jordan of the West Virginia Bureau
of Public Health review the new standard and what it means to small
Planning for the future is sometimes a hard thing to do when an
operator is struggling with day-to-day utility problems. But, planning
for an emergency or natural disaster is an absolute necessity. This
tip sheet developed from a CD-ROM produced by the Midwest Technical
Assistance Center gives you ideas about what to include in your
own emergency plan.
Earth Filtration for Drinking Water
Diatomaceous earth (DE) filtration produces high-quality, low-cost
drinking water using the skeletal remains of small, single-celled
organisms as the filter media. The process is a U.S. EPA approved
technology for meeting Surface Water Treatment Rule requirements.
This Tech Brief discusses DE filtration, giving an explanation of
the process, its history, monitoring and operating requirements, and
sources of more information.
Effect on Corrosion in Drinking Water Systems
Small water treatment systems face a dilemma. Compliance with the
Ground Water Rule requires systems to monitor for and disinfect
microbiological contamination. The most common treatment method
is adding chlorine to the water, which can lead to corrosion in
the system, throwing the system out of compliance with the Lead
and Copper Rule. This two-page pull-out outlines research sponsored
by the Midwest Technology Assistance Center that studied the level
of corrosion that may occur with chlorine disinfection.
