The city of Modesto, Calif., agreed to pay a $165,000 fine...
The Old West had small populations and certainly never had
to worry about water quality. You can watch any Old West movie and see cowboys
dipping their cups into a barrel outside the local saloon. Most of us cringe at
what could be in there, but they just never worried.
Now, the face of the West is very different. The "New
West" has emerged full of concerns and new laws that make water treatment
necessary and some that make it harder to sell. California is well-known for
its progressive way of thinking. Although often its tactics may be questioned,
many people anxiously wait to see what will be next. Will there be more bans?
Stricter regulations? The state's legislation continually has been
challenged by the Water Quality Association, NSF International, water treatment
professionals nationwide and other organizations. With all of this in mind,
let's take a look at some things that are happening in the Western
tertiary butyl ether (MTBE) continues to make headlines as gas companies continue
taking steps towards eliminating its use in gasoline. Chevron U.S.A., Inc.
announced its latest efforts to discontinue its use of MTBE in all gasoline
sold in California. Its phaseout is expected to be complete by May of this
year, finishing ahead of California Governor Gray Davis' deadline of
December 2003. Chevron's gas uses ethanol instead of the more widely used
MTBE, a possible carcinogen. MTBE was the product of choice to reduce air
pollution until it was pinpointed as a water contaminant. Ethanol is the only
approved oxygenate for California gas.
is becoming more common in the the Southwest region of the United States.
Drinking water supplies stemming from the Colorado River have seen a rise in
perchlorate levels. The river serves approximately 20 million people, and the
contamination has forced hundreds of wells to be closed. Most of the
perchlorate manufactured in the United States is used as the primary ingredient
of solid rocket propellant. Wastes from the manufacture and improper disposal
of perchlorate-containing chemicals will demand treatments such as biological
treatment and ion (anion) exchange systems with other technologies continually
concerns and issues relating to the California law SB 1006 continue to arise.
The law went into effect January 1. This bill states that water districts can
ban automatic water softeners if they meet a set of state-mandated criteria
including being out of compliance with waste discharge or water reclamation
standards. Also, districts must identify and take steps to reduce all sources
of salt, and they must show that banning softeners would bring the district
