90189H-APH CON-6 <br /> Nearby property owners and businesses were concerned about two issues: <br /> possible health risks to employees on the site as a result of past, <br /> present, or future exposure to hazardous substances from the 2041 site; and <br /> potential effects on property values and future liability if hazardous <br /> substances had reached or would reach their properties. <br /> Level of concern was highest among employees at the concrete plant, who <br /> had seen blue-colored liquid from the Lika plant overflow onto their <br /> property many times in the past. They wondered whether soil on the site <br /> might still contain contaminants deposited from the overflow liquid. They <br /> requested that soil on their property be sampled and analysed to determine <br /> whether contaminants are present. Soil samples were collected in September <br /> under supervision of DHS, and analysed for lead, nickel , copper and <br /> arsenic. Results of lab analyses were reported in November. Highest <br /> concentrations of lead, nickel and copper were detected in soil samples <br /> along the eastern fenced property line. These samples were taken closest <br /> to the process area at the former Lika facility and in an area where known <br /> spills are reported to have drained. The samples along the western fenced <br /> property line of the concrete plant have some of the lowest concentrations <br /> of lead, nickel and copper. Background samples showed that raw materials <br /> for concrete production used at the plant have measurable trace <br /> concentrations of lead, copper, arsenic, and nickel . These data suggest <br /> that spills originating from the former Lika facility only contaminated <br /> soil along the eastern fenced property line common to the Lika facility and <br /> the concrete plant. As a result of the findings, the northward extent of <br /> soils to be remediated was expanded along the eastern boundary of the <br /> concrete plant. <br /> The supervisor at the busing/trucking firm at 2005 Navy Drive thought <br /> his employees might be concerned, and requested a copy of the draft RAP to <br /> make available to them. However, he had no inquiries from employees after <br /> posting the fact sheet and notice of availability of the draft RAP. <br /> H-7 <br />
