On May 6, 1992, New Times began a series of investigative reports detailing extensive groundwater pollution linked to Motorola, an $11 billion multinational electronics manufacturing company that is the state's largest employer. Among the findings:

ýMotorola's two flagship plants have been linked to severe contamination of two separate aquifers in the Valley--one in Scottsdale and one in east Phoenix. Both sites have been placed on the federal Superfund list. Thus far, Motorola has invested nearly $30 million in cleanup efforts at both sites.

ýCity water officials say all Valley drinking water is now safe, largely because they have abandoned the polluted groundwater sources in favor of water supplied by manmade desert lakes.

ýThe Motorola Government Electronics Complex, at Hayden and McDowell in Scottsdale, is the largest of four suspected polluters of the north Indian Bend Wash aquifer, which once was considered a potable drinking-water source for 350,000 people. Today most of its untreated water is unsafe for drinking. The Superfund site is bounded on the north by Chaparral Road, on the east by Pima Road, on the west by Scottsdale Road and on the south by McKellips Road. Cleanup of the drinking water is expected to begin in 1993. No one knows for sure how long residents were exposed to contaminated drinking water. In-depth health studies have not been performed.

ýThe Motorola semiconductor plant at 52nd Street and McDowell in Phoenix is linked to a plume of groundwater contamination that is so vast officials have been unable to chart it since it was discovered ten years ago. The plume now extends from the plant west beyond 24th Street and south beyond Van Buren Street. The groundwater near the plant has not been used for public drinking-water supplies, although state law considers it a future drinking-water source. The contaminated plume originating at Motorola has traveled into one of the Valley's most productive aquifers and officials fear that it might someday contaminate virgin drinking-water supplies. Motorola recently began pumping water from the aquifer, stripping it of TCE, and using the water for manufacturing.

ýThe contamination at both sites was caused by dumping of thousands of gallons of industrial solvents into unlined lagoons, dry wells and down the drain, federal and state records say. Such industrial dumping was not illegal in the 1950s, 1960s and 1970s. However, at least as early as 1966, the company knew that dumping solvents into unlined lagoons could have serious environmental consequences. ýThe contamination problem was exacerbated at different times by state and federal regulators entrusted with protecting the groundwater. In Scottsdale officials allowed substantial pollution of the Indian Bend Wash by not cementing old wells that cascaded contaminated water into the drinking-water aquifer. In Phoenix city officials lobbied to have the state, notorious for lax standards, not the EPA, be the lead agency to oversee "cleanup" of the 52nd Street site. Without sufficient federal scrutiny, the state allowed its largest employer to take over the cleanup reins. For several years, the state permitted the company to collect and interpret environmental data upon which all key decisions were made without first checking the data for accuracy.

ýThe principal contaminant at both sites is the industrial solvent TCE, or trichloroethylene, which the federal government classifies as a suspected carcinogen. The health effects of TCE are hotly disputed, but it has been linked with leukemia as well as kidney, liver and central nervous system disorders. Measurements of TCE-contaminated groundwater near the Motorola 52nd Street plant are among the highest recorded in the United States.

ýTwo separate class-action lawsuits against Motorola are now winding their way through Arizona courts. The plaintiffs allege that the contamination has caused health problems and declining real estate values. In court papers, Motorola has denied both allegations.

ýState regulators abdicated their public relations responsibilities to Motorola's consultants from 1985 to 1991. During that time, only one public meeting was held with citizens.

ýSince 1985 there has been a raging national debate over whether TCE and other chlorinated solvents can be removed from the nation's aquifers. Some scientists say it might take 1,000 years for aquifers to be purged of TCE.

ýMotorola's own consultants informed the state in 1986 that it might be impossible to remove the TCE from beneath the plant.

ýCitizens were not informed of the debate over the cleanup of their aquifer by the local news media, Motorola or state and federal regulators.

ýMotorola admits it has back-billed the Department of Defense for undisclosed cleanup costs of the Indian Bend Wash Superfund site.

ýIn the waning days of the current Bush administration, EPA officials are quietly redesigning Superfund policy. The new Superfund plan will shift funds and attention to those few sites that pose immediate "risks" to public health. Groundwater contamination sites not deemed an immediate "risk," such as the Motorola 52nd Street site, will be placed on a long-term cleanup list. The EPA says the program will streamline Superfund; environmentalists say the plan goes against the intent of the Superfund law, which is to hold all polluters accountable. In Arizona the director of the Department of Environmental Quality says the state Superfund is moving toward the model of cleaning up contaminated sites according to their "risk."

I moved to Maryvale in 1972 when i was seven, i than bought my first home there as well. moved out in 1995. Through the years I met some good people. A few has become life long friends. One man I met when i first moved to Maryvale and bought his first home there as well now has been diagnosed with leukemia.  Trichloroethylene is known to cause leukemia. So now no one or no company that caused the contamination in the water with  Trichloroethylene is helping him in any way with medical bills or any aide at all. They say that the case action lawsuite has ben settled and that whats done is done. THATS A BUNCH OF B.S.


Not only did I attend East High School, I worked at the 52nd Street Plant (SG). In fact I'm pretty sure there are many former Longhorn's that also did as well. I remember the open wells of these chemicals that included acetone and Freon, among many. Sometimes when the wind blew south you could smell the fumes quite heavily if you were out at PE or on the baseball or football fields. Did these chemical plumes permeate the very water we drank there? I'm sure that we didn't know what ramifications would come later, nor did we care; We were young and care-free. At the plant itself, though chemical safety was stressed, the simple safeguards they had in place, were probably not enough. Walking to and from your car in the East and SE company parking lots, the fumes were so strong, it could literally take your breath away. I have known about the clean-up for sometime. But the thought that maybe some fellow Longhorns or residents may have paid with their lives angers me. Kind of tarnishes" The Best Years of Our Lives".


@rikkifin That is corporate America for you.  Now that some years have passed 

i lived in Maryvale since i was 7 years old and i bought my first home there as well. I have made a lot of lifelong friends through the years. I now have a friend that have done the same but now he has leukemia. And no one or any companies are willing to help them in any way with any medical expenses or any kind of aid at all. Trichloroethylene is known to cause leukemia . It is said that the case action law suite has been settled.And no one can be held accountable
