Notes

1.

Benzene, toluene, ethylbenzene, and xylenes: MTBE (methyl tert-butyl ether) may be added upon request.

2.

Total Petroleum Hydrocarbons as Gasoline: JP-4, mineral spirits, or stoddard solvent may be added upon request. Reporting limits may be higher for fuels other than gasoline.

3.

Total Petroleum Hydrocarbons as Diesel: motor oil, commercial jet fuel, JP-5, hydraulic oil, transformer oil, or Bunker C may be added upon request. Reporting limits may be higher for fuels other than diesel.

4.

CA LUFT:  California Department of Health Services Leaking Underground Fuel Tank Manual, October 1989. "Method" indicates that the prep method is an integral part of the analytical method.

5.

Holding times specified in 40CFR 136.3 Table 2 (Clean Water Act/ NPDES) and SW-846 Table 2-36 Revision 3, December 1996.

6.

X/Y:  X days from sample collection to extraction, then Y days from extraction to analysis.

7.

Samples should be kept at 40 from time of collection until analysis. Preserved containers can be supplied by C&T. HCL:   hydrochloric acid to pH < 2, H2:SO4::sulfuric acid to pH < 2, NaOH: sodium hydroxide to pH > 12

8.

Free chlorine should be neutralized with 0.008% Na2S2O3

9.

Prep method EPA 5035, using Encore sampling devices, may be used in place of EPA 5030; contact lab for details.

10.

100g minimum for TCLP (metals or SVOC) extraction. 50g required for each analysis.
