Subject: [CPEO-BIF] Motorola 52nd Street plume, Phoenix, Arizona "larger than previously thought"
ADEQ makes case that Superfund site is larger than previously thought

PHOENIX (3TV/CBS 5) - The Arizona Department of Environmental Quality is urging the EPA to take over efforts to clean up contaminated groundwater in west Phoenix. In doing so, the state agency is essentially arguing that the Motorola Superfund site that stretches from the Papago Buttes to downtown Phoenix, is actually much bigger.

In the most recent letter on the matter, dated June 24, ADEQ Waste Programs Division Director wrote, "Multiple lines of evidence in the existing documents and data support that the TCE plume originating from the M52 (old Motorola) facility...has migrated beyond the western boundary (of the Superfund site.)"

"What that ADEQ memo shows is that, yes indeed, this is a contiguous plume. It should’ve been part of the original Superfund site. And it needs to be incorporated as part of that Superfund site today," said Scott Meyer, who is the president of Don't Waste Arizona, an environmental group that has been involved in fighting for more testing and cleanup efforts over the past 30 years.
