If the system serves more than one unit or structure, samples shall be collected from a representative distribution of the system as well as the corresponding areas that it serves until the contamination is delineated, decontaminated, and determined to be below the decontamination standards established in this rule.(o) If there is a kitchen, three 10 cm. x 10 cm. areas, 100 square centimeters, shall be wipe sampled from any surface most likely to be contaminated including the counter top, sink, or stove top, and from the floor in front of the stove top or any other location where contamination is suspected.(p) If there is a bathroom, three 10 cm. x 10 cm. areas, 100 square centimeters, shall be wipe sampled from any surface most likely to be contaminated including the counter top, sink, toilet, shower, or bath tub and any other location where contamination is suspected.(q) If there are any appliances, one 10 cm. x 10 cm. area, 100 square centimeters, shall be wipe sampled from the exposed portion of each appliance. If multiple appliances are present, each wipe sample may be a composite of up to three 100 square centimeter areas on three separate appliances, provided that the surfaces most likely to be contaminated are tested.(r) If there is any other enclosed space where an illegal drug operation occurred, hazardous material was stored, or where staining or contamination is present, three 10 cm. x 10 cm. areas, 100 square centimeters, shall be wipe sampled from the surfaces most likely to be contaminated. (5)(a) The decontamination specialist and owner of record shall ensure that VOC sampling and testing is conducted in accordance with this rule.(b) A properly calibrated PID or FID capable of detecting VOCs shall be used for testing.(c) The background concentration of VOCs shall be obtained by testing three exterior areas outside the areas of contamination and in areas with no known or suspected sources of VOCs.
