This brochure is to inform certified lead-based
paint professionals of requirements to use EPA-
recognized (NLLAP)  laboratories for  analysis
of samples collected in residential housing and
child occupied facilities.
Testing for Lead?
There  are two important  considerations to
achieve accurate lead measurements.  The first
is the collection of appropriate samples.  EPA,
numerous states and  tribes  have  established
programs   to  certify  inspectors  and   risk
assessors so collection of paint chip, dust and
soil    samples will be performed according to
current   standards.     To   obtain  additional
information  about  current  requirements for
collection of paint, dust, or soil samples, call
the National  Lead Information Center at  1-
800-424-LEAD or visit Internet site www.epa.
The  second aspect of an accurate measurement
takes place  in the  laboratory.    EPA  has
established the  National Lead  Laboratory
Accreditation   Program      (NLLAP)  to
recognize  laboratories that  demonstrate the
ability to accurately analyze  paint chip, dust or
soil samples for lead.   A laboratory may choose
to  be recognized for one, two, or all  three of
these types of samples.
Many  states   and  tribes  have  developed
requirements for lead-based paint activities and
have received authorization to implement their
programs from EPA.   The majority of these
states and tribes require  the use of NLLAP-
recognized laboratories for  analyzing  paint,
dust,  or  soil  samples collected  during risk
assessments,   lead   hazard   screens,   and
inspections covered by their programs.
In states  and tribes that do not have an EPA
authorized  program  by  March   1,   2000,
EPA will administer a federal program  with
requirements  for  the conduct  of  lead-based
paint  activities  and  the  use  of NLLAP-
recognized laboratories.
For  additional information  about  what  is
required  in your  locality, or who to contact
about requirements in any states or  tribal lands
where you  plan to offer testing services,  call
the National  Lead Information  Center  at
How Does NLLAP Work?
The NLLAP has been established by EPA's
Office of Pollution Prevention and Toxics.
NLLAP  provides the public with a list of
laboratories that have met EPA requirements
and demonstrated the capability to accurately
analyze paint chip,  dust,  or  soil samples for
lead.  All laboratories recognized by NLLAP
are  required   to  undergo   on-site  audits
conducted   by  accrediting  organizations
participating in the  NLLAP, and to perform
successfully on a  continuing basis in the
Environmental  Lead  Proficiency  Testing
(ELPAT) Program.  ELPAT is a proficiency
testing program established  by the National
Institute  for Occupational Safety and Health
(NIOSH), EPA, and the American Industrial
Hygiene Association (AIHA).
Currently, EPA recognizes the AIHA and the
American   Association   for   Laboratory
Accreditation   (A2LA)   as  accreditation
organizations  participating  in the  NLLAP
laboratories audit process.  To learn about a
specific  laboratory's  past   performance  or
complaint   history,  contact   AIHA  at
(703) 849-8888 or A2LA  at (301) 644-3200.
