The two buildings on the property were planned on being demolished in <br />the near future. The sampling listed below was from Building 1 on the subject property. <br />Methodolo ty <br />Sampling of painted surfaces was performed utilizing a NITON XL-300 Series Lead <br />Analyzer. This equipment is a direct -read analytical device that does not require substrate <br />correction and does not report inconclusive readings. <br />Paint/coatings are considered to be lead -based, as defined by HUD/EPA guidelines, if they <br />contain greater than one milligram per square centimeter of lead. Paint whose lead levels <br />were less than one milligram per square centimeter was reported as negative (no lead <br />detected). <br />Scope of Work <br />A complete lead -based paint inspection was not performed. Rather, XRF testing was <br />performed on any surface where paint was flaking from the substrate material. The building <br />was planned on being demolished. Sides of the building were labeled with letters A-D <br />starting at the side facing the street and continuing clockwise. <br />Results <br />Results of samples are as follow: <br />Sample <br />1 <br />2 <br />3 <br />4 <br />5 <br />6 <br />7 <br />8 <br />9 <br />10 <br />Location <br />Calibration <br />Calibration <br />Calibration <br />Building 1 Exterior, Side A <br />Building 1 Exterior, Side B <br />Building 1 Exterior, Side B <br />Building 1 Exterior, Side C <br />Calibration <br />Calibration <br />Calibration <br />*results reported as milligram per square centimeter <br />Structure Sampled <br />N/A <br />N/A <br />N/A <br />Brown wood door frame <br />Brown wood service door frame <br />Brown wood garage door frame <br />Brown wood garage door frame <br />N/A <br />N/A <br />N/A <br />Results* <br />N/A <br />N/A <br />N/A <br />Negative <br />Negative <br />Negative <br />Negative <br />N/A <br />N/A <br />N/A <br />
