EPA says that 5 residential properties tested “high” for Chromium and that further tests are needed to determine what type of chromium is present on these properties. Did EPA test the adjoining properties to see if they have chromium as well?

If the properties on either side of the subject property participated in the sampling, EPA analyzed the soil for total chromium.  The five properties where EPA found a potential risk due to chromium were isolated, randomly distributed, and not adjacent to one another, therefore there is no indication that the soil in a particular area of the neighborhood was impacted by wastes disposed of in the landfill.
