horizontal dust lead levels below and nearest the
surface equal or exceed Dust-Lead Hazard levels in

Any chewable lead-based paint surface with teeth
marks.
Damaged or deteriorated lead-based paint impact

NOTE: Review lead inspection/risk assessment sampling, analysis, QA/QC and
reporting tasks that will be performed in Paragraphs 2.0 through 2.4. Typically, 135 XRF
shots are taken in a three-bedroom home with a cost range per shot of

each. Six to eight dust wipes are typically sampled per unit during most risk assessments.
Three paint chip samples should be allowed for each unit, either to confirm XRF readings
or for deteriorated paint or paint on small surfaces. A total of two composite soil samples
per unit are also typical for most risk assessments. One QA dust spike sample for each 50
field wipes, and QA paint chip samples at 1% to 5% of total paint chip samples collected
should be allowed. Typical lab cost for lead dust, pa int chip, and soil can range to .00
per sample keeping in mind that an NLLAP recognized lab must be used. The prices
may vary depending on geographical region. Check with qualified labs in the area that
