EP 1110-1-29
31 Aug 01
One dust sample shall be collected from the entryway nearest to the soil treatment work
area.
Dust samples shall be collected for analysis by single surface wipe sampling. Gloves shall always be
changed prior to and after collecting each sample. After donning gloves, do not touch anything other
than the wipe and surface that will be sampled. If a wipe is dropped, or contact is made outside the
area that will be sampled, discard the wipe and sample another, undisturbed area. In each unit that will
be sampled, discard the first wipe from the dispenser prior to initiating sampling. Fold each wipe
completely before inserting it into the collection tube.
The Contractor shall collect wipe samples in accordance with ASTM's Standard Practice for Field
Collection of Settled Dust Samples Using Wipe Sampling Met hods for Lead Determination by
Atomic Spectrometry Techniques (E 1728), using wipe materials that meet the requirements of
Standard Specification for Wipe Sampling Materials for Lead in Surface Dust (E 1792). (See
AIHA web site for a listing of wipe vendors meeting ASTM Method E1792 criteria.)
2.2.2.2
Soil Sampling
******************************************************************************
NOTE: In some parts of the country, particularly the South and coastal areas, family
housing may have accessible crawl spaces that are used as play areas by small children.
Samples should be collected from the bare soil in these crawl spaces if they have been
affected by the lead hazard control activities, and clearance sampling is required.
******************************************************************************
Each composite sample shall include no less than two (2) and no more than ten (10) sub-samples, each
collected from distinct locations roughly equidistant from each other along an axis. Sub-samples along
drip lines shall generally be collected at locations two to six feet from each other. In other sampling
locations (such as play areas) sub-samples shall be collected from roughly equidistant points along each
leg of an X-shaped pattern. The samples shall include only those sides of the building that are subject to
the lead hazard control measures. [One composite soil sample shall be collected from all sides of the
unit's perimeter.] [Only soil from the perimeter of treated faces of the subject unit shall be sampled. A
second composite soil sample shall be collected from nearby play areas.] The Contractor shall collect
composite soil samples from [ ] [the drip line] [play areas of bare soil] [bare soil from rest of the yard
(i.e., non-play area)] [the bare soil in the crawl space of each unit subject to the clearance inspection].
The Contractor shall collect bare soil samples in accordance with the procedures outlined in the most
current edition of Standard Practice for Field Collection of Soil Samples for Lead Determination
by Atomic Spectrometry Techniques, ASTM Standard E 1727.
