Were zinc, nickel, chromium or methyl ethyl ketone (MEK) tested for in the Acreage samples?
• The water samples were not analyzed for zinc and nickel, but they were for total chromium and MEK. MEK is also known as 2-butanone and that is the name it is listed under in EPA method 8260. While the samples were not specifically tested for hexavalent chromium, the results of tests for total chromium include hexavalent chromium. No speciation work (to determine the amount of hexavalent chromium) was required since none of the samples exceeded the criteria for chromium. February 2010 (water only) • The water samples were analyzed for zinc, nickel, total chromium and MEK (2-butanone). March 2010 (water and soils) • Both the water and soil samples were analyzed for zinc, nickel, total chromium and MEK (2-butanone). April 2010 (water and soils) • Both the water and soil samples were analyzed for zinc, nickel, total chromium and MEK (2-butanone). Summary: As noted, DEP has tested for the four (4) contaminants listed in Attorney Srolovic’s June 16, 2010 e-mail, and based on the analytical
