The paint chip sample collected from the western portion <br /> of the north wall of the warehouse building had a lead concentration of 298,086 ppm, well above the <br /> DHS standard. Laboratory analytical results of the paint chip samples analyzed for lead are summarized <br /> in Table 10, on the next page. Laboratory report sheets indicating analytical methods used, detection <br /> • limits, and the results of the analyses are included in Appendix B. <br /> IW CONDOR <br />
