Collecting a sample for A. A. Analysis for Lead:
1. Select an appropriate leakproof container. If Nasco Whirl-Pak bags are not available, you may use a standard Zip-loc type sandwitch bag (*not* the "fold-top" kind). If using Zip-loc sandwitch bags, it is recommended that the sample be "double-bagged". For samples OTHER THAN complete paint chips, such as dust or soil, select a RIGID container, such as a plastic film can (NO glass containers, please).
Note: EPA would advise latex gloves when handling suspect lead-containing materials.
2. Carefully place the sample in the container, evacuate as much air as possible, and seal.
* a. Paint chips: about two square inches [or a 2 inch by 1 inch piece]
* b. Dirt or soils: about 1/4 cup, or nearly fill the container.
* c. Dust wipes: wipe a measured 1 square foot area with a TX811 OpticalPad wipe.
* d. Water: We are not able to accept water samples at this time, due to lab requirement for pre-acid-treating the containers.
3. Label and/or number each sample. Provide information on *each* sample to include:
* a. Sample number
* b. type of material, such as "white trim paint", "brown exterior paint", etc.
* c. location, such as "master bedroom window", etc.
A sample log sheet is provided, which you may simply print out on your computer.
Log Sheet
4. Check to be sure the number on each sample container (bag) matches the sample number on the log sheet.
5. Address the envelope or package to:
"HAND CANCEL"
HMA
1933 Davis Street, Suite 303
San Leandro, CA 94577
(the words "hand cancel" are so the post office doesn't run it through the automatic metering machines and risk rupturing the sample bag.)
6. Be sure to enclose:
* a. Sample, sealed in it's container (bag), and identified with sample ID number
* b. Sample log sheet
* c. Check, bank draft, or money order made out to HMA, Inc. for US$35.00 per sample.
* d. Name, address and phone number where results are to be sent.
7. Mail to above address.
