Attachment B - SUMMARY OF RECOMMENDED PROCEDURES FOR SAMPLE COLLECTION, PRESERVATION, AND STORAGE

a. Collection method should include appropriate liners.

b. Amount of sample required by the laboratory to perform the analysis (wet weight or volume provided, as appropriate). Miscellaneous sample size for sediment should be increased if auxiliary analytes that cannot be included as part of the organic or metal analyses are added to the list. The amounts shown are not intended as firm values; more or less tissue may be required depending on the analytes, matrices, detection limits, and particular analytical laboratory.

c. All containers should be certified as clean according to USEPA (1990c).

d. These holding times are for sediment, water, and tissue based on guidance that is sometimes administrative rather than technical in nature. There are no promulgated, scientifically based holding time criteria for sediments, tissues, or elutriates. References should be consulted if holding times for sample extracts are desired. Holding times are from the time of sample collection.

e. NOAA (1989).

f. Tetra Tech (1986a).

g. Sample may be held for up to one year if five to 20##C.

h. Polypropylene should be used if phthalate bioaccumulation is of concern.

i. Two weeks is recommended; sediments must not be held for longer than eight weeks prior to biological testing.

j. USEPA (1987a); 40 CFR Part 136, Table Ill.

k. Plumb (1981).

l. If samples are not preserved to pH < 2, then aromatic compounds must be analyzed within seven days.

m. Tetra Tech (1986b).
