Current COCs can be managed. The area of elevated arsenic could be excavated, with confirmation samples collected. However,
the asphalt surface can act as a barrier to exclude the industrial/commercial ingestion exposure pathway, as long as it is left in place and maintained, and the construction worker ingestion exposure pathway could be excluded through use of an institutional control Construction Worker Notification attached to the property deed.

Additional Property Attributes

The subject property is located in Alton, Illinois and consists of most of the block between Piasa and Belle, and Fourth and Fifth Streets Figure 1. At the time of the SI, the Site was developed as a pay parking lot. Two commercial buildings located along the southern edge of the block along Fourth Street are outside of the subject property. The Site is located in the downtown district of Alton, surrounded by commercial businesses. The Mississippi River is located four blocks south of the Site. The subject site consists of approximately one acre of land and has been developed since at least 1885. The site is currently developed as a pay parking lot.

Former Use: The site is currently developed as a pay parking lot. Additional uses of the site have included a filling station, auto repair facility, a buggy company, and residences. Surrounding properties have been developed since at least 1885 and have included iron and brass foundries and machine shops two � to the north and east of Site, a forge and manufacturer of mining tools, residences, a filling station, auto repair facility, Sears Roebuck, and Hayner Library. Based on the results of this investigation, there do not appear to be areas of significant soil or groundwater contamination on the subject site. There were no field observations of obvious impact such as staining, odors, or elevated PID readings. However, there were exceedances of some IEPA Tier 1 remediation ives. Constituents of concern included metals in soil arsenic, mercury, cadmium, chromium, lead, selenium, and silver, and benzoaanthracene in groundwater. In addition, the historical site use as a gasoline service station in the southwest corner of the site remains a potential issue. Due to the gas main which was located in the vicinity, sampling was not conducted in that corner for safety reasons. Additional investigation, such as using a private locating service, could more accurately locate gas lines in the area including the tie-in to the building. In addition, test pitting or use of ground penetrating radar may be able to verify the presence or absence of tanks in the area. Without additional investigation, the southwest corner of the site remains a potential risk. The area of elevated arsenic could be excavated, with confirmation samples collected. However, the asphalt surface can act as a barrier to exclude the industrial/commercial ingestion exposure pathway, as long as it is left in place and maintained, and the construction worker ingestion exposure pathway could be excluded through use of an institutional control Construction Worker Notification attached to the property deed.
