PHOENIX (AP) - Officials with the Arizona Department of Environmental Quality say a contaminated site in Phoenix has been cleaned up.

The agency says water samples show cleanup levels have been reached at the site near 38th St. and Indian School in Phoenix so it will be removed from a state registry that includes properties in need of remediation.

Officials say the site was originally polluted with tetrachloroethene, or PCE, which was commonly used in dry cleaning.

The site had been on the state registry for years.

Following the use of a vapor extraction system to treat the soil, contamination was still present at groundwater monitoring wells.



Officials followed up with chemical oxidation injections to reduce the concentration of the remaining contamination and subsequent sampling indicated cleanup levels were achieved.
