construction or maintenance histories must be evaluated individually. Housing unit
access and common area sampling strategies must also be addressed as a part of sampling
strategy.
******************************************************************************
[The Contractor shall perform a lead inspection/risk assessment on each unit identified in this
SOW.]
[The Contractor shall randomly select (see Glossary) the housing units for lead inspection/risk
assessment from the total unit population. The minimum number that must be randomly selected
shall be determined by using Table B-1 (Appendix B). The Contractor shall randomly select
alternate housing units beyond the minimum number required in Table B-1 to provide flexibility
based on information obtained on site and the success in gaining access to the selected housing
units. The procedure used to randomly select the units shall be specified in the Project Work
Plan.]

Data Quality Objectives (DQOs)
******************************************************************************
NOTE: Refer to EPA's "Lead; Identification of Dangerous Levels of Lead", Final Rule,
66 FR 1206, 5 January 2001, and "Requirements for Notification, Evaluation, and
Reduction of Lead-Based Paint Hazards in Federally Owned Residential Property and
Housing Receiving Federal Assistance"; Final Rule 24 CFR Part 35, September 15, 1999
for guidance in applying the action levels to use for the project.
******************************************************************************
The Contractor shall meet the project-specific DQOs (see Glossary) for the sampling, analysis
and Quality Assurance/Quality Control (QA/QC) by meeting the requirements of Paragraphs 2.2
and 2.3. DQOs must be met in order to provide project required data quality. The data thus
collected shall be compared to the action levels defining lead hazards provided in Table A-1
below. If the data are below the action levels, recommendations shall be made in the Lead
Inspection/Risk Assessment Report in accordance with Paragraph 2.4.10.
Table A-1
Lead-Based Paint and Hazard Leve ls for a Lead Inspection/Lead Risk Assessment
Sample Matrix/Surface Type
Action and Lead Hazard Level1
1.0 mg/cm2 (XRF)
Lead-based paint
0.5% by weight or 5,000 g/g (paint chip if not used
in conjunction with XRF measurements. If paint
chip is used in conjunction with XRF measurements,
lab must report paint chip lead loading in units of
mg/cm and must specify paint chip sample
