High levels of arsenic, lead found on Clarkdale properties
Town approves soil removal access agreements

CLARKDALE – Tuesday, the Common Council of the Town of Clarkdale approved action regarding the execution of various soil removal access agreements for town properties at a special meeting.

Exceedances of arsenic, and sometimes lead, were found in the soil around town-owned properties, including the courthouse; police station; town hall; clubhouse; utility department; town yard; and various allies in both lower and upper Clarkdale and Patio Park.

These properties qualify for soil remediation and landscaping.

The samples were taken during the first round of testing, removed from the first 12 inches of soil. More samples could be taken from 12 to 24 inches of soil if necessary.

Testing continues, said Town Manager Gayle Mabery during the presentation.

Mabery said she just received a new packet of results a few days again, and will continue to present the data before the council for public record.


The Clarkdale copper smelter was operated by the United Verde Copper Company from 1915 to 1932 and by Phelps Dodge Corporation from 1935 to 1953.

As the corporate successor to Phelps Dodge Corporation, Freeport Minerals entered into the Arizona Department of Environmental Equality (ADEQ) Voluntary Remediation Program to investigate potential impacts to soil from historical smelter operations.

For the past 15 months, Clarkdale soil samples were sent to an independent laboratory and tested to determine the concentrations of arsenic, copper, lead, tin, zinc, and boron in the soil.

If concentrations of one or more of the metals exceed soil target cleanup levels, Freeport will remove and replace the impacted soil and restore the landscaping to similar condition. The program is free and voluntary.

The soil testing has the oversight of both the ADEQ and the Yavapai-Apache Nation Environmental Protection Agency.

Letters about the program have been sent to property owners in the expanded area. If a property owner gives permission for soil testing to be done, and the results come back positive, they can agree to have the contaminated soil removed.

So far, between 80 and 90 percent of the tested areas have an exceedance, said Mabery.
