Table 3. Concentrations of selected volatile organic compounds in groundwater samples from monitoring wells and piezometers collected by the U.S. Geological Survey at Operable Unit 1, Naval Undersea Warfare Center, Division Keyport, Washington., 1999–2008.

[All data except those shaded were published previously in Dinicola and others (2002), Dinicola (2003), Dinicola (2004), and Dinicola and Huffman (2004). Laboratory data qualifier codes, such as “D” for dilution, are not shown. Volatile organic compounds (VOCs); PCE, tetrachloroethene; TCE, trichloroethene; cis-DCE, cis-1,2-dichloroethene; trans-DCE, trans-1,2-dichloroethene; VC, vinyl chloride; 1,1,1-TCA, 1,1,1-trichloroethane; 1,1-DCA, 1,1-dichloroethane; CA, chloroethane; 1,1-DCE, 1,1-dichloroethene; total BTEX, sum of benzene, toluene, ethylbenzene, and xylene; total CVOCs, sum of chlorinated volatile organic compounds. Abbreviations: E, estimated value; M, presence verified but not quantified; µg/L, microgram per liter; dup, duplicate; blank, field blank; <, actual value is less than value shown; ND, not detected; –, not analyzed]
