Appendix C 249 WATER-SAMPLING DATA IN TABLES C-3 AND C4 The committee reviewed Camp Lejeune water (CLW) documents for water-quality sample in- formation relevant to Hadnot Point. The Marine Corps provided guidance on which CLW documents con- tained water-sampling data (Table C-2). CLW documents are publicly available from the Agency for Toxic Substances and Disease Registry (CD accompanying Maslia et al. [2007]). They are indexed by the first page number of a file; often, specific information abstracted from the files by the committee came from later pages in files. The committee reviewed at least one CLW for each sample listed in the table, even if sample information was summarized in multiple CLWs. For each sample, the committee reviewed at least the primary CLW, defined as the original laboratory report of the water-sample analysis results. If the committee looked at other CLWs in addition to the primary laboratory report, they are listed in the “Secondary CLW” column. Additional review was most commonly needed to determine the field sam- pling date. Tables C-3 and C-4 summarize all samples abstracted by the committee for the Hadnot Point wa- ter-supply system. The universe of possible samples was restricted to those taken in the period from the earliest known water-sampling date in October 1980 through February 7, 1985. Because of removal of contaminated wells from the water-supply system, the committee believes that February 7, 1985, is the last date when samples were taken that would potentially reflect the contaminated water supply. All later samples were believed to have been taken after any measurable residual contamination would have re- mained in the water-supply system. Results of measurements in distinct samples were included in the ta- ble for each unique laboratory report. (See additional comments on this topic below.) There is a separate table of analytic results from mixed water samples taken from the water-distribution system (either before or after treatment; Table C-3) and a table of results from potable-water well samples (Table C-4). The two tables record concentrations of trichloroethylene (TCE), tetrachloroethylene (PCE), benzene, 1,1,1- trichloroethane (TCA), 1,1-dichloroethylene (1,1-DCE), trans-1,2-dichloroethylene (1,2-DCE; this com- pound was assumed if only “DCE” was listed in primary or secondary CLWs), methylene chloride (MC), toluene, and vinyl chloride (VC). Units are micrograms per liter (parts per billion), and the concentrations that appear on the laboratory sheets are recorded directly in the table. “ND” means not detected and ap- pears when it was recorded by the laboratory. Occasionally, a laboratory used other indications for “not detected,” such as “<1.0” or “<2.0”; in such cases, these values appear in the table. A dash, “—”, appears when the document format suggests that a compound was not analyzed for. When the primary laboratory sheet listed the method detection limit, this value was recorded in the “DL” column of the table. That col- umn was left blank when the information was not explicitly available. Additional sample information is contained in the “sample date” and “sample location” columns. The sample date is intended to be the date on which the sample was collected in the field. Because many of the primary laboratory sheets list the date on which a sample was received by the laboratory, secondary information was needed to make a judgment about the field collection date. This is one example of when “secondary CLWs” were consulted. “Sample location” is a description of the base location where the sample was obtained. Separate samples were defined on the basis of the presence of a unique laboratory report, so there are distinct entries in the table for samples that were collected at the same location on the same day. The committee does not have information to determine definitively whether those are pure duplicates (one sample split into two vials for laboratory analysis) or separately collected samples. Regardless, measure- ments on samples collected at the same location on the same day are bound to be more similar than other samples because of their proximity in space and time. In particular, the data include a pair of measure- ments collected on the same day from well 651. It is unclear from the source documents whether those are measurements on a split sample or measurements on two samples collected on the same day. In addition, there are several instances of multiple samples from the same location in the mixed water samples; in these cases, the sample descriptions have minor distinctions (such as cold-water tap vs hot-water tap or filter 1 vs filter 2) to suggest that the samples were not split.
