10 APPENDIX B Sediment Chemistry Data Terms and Analyses

11 Data Terms In the discussion of bulk sediment and contaminant data, the following terms are used. Nearfield refers to all regional stations located west of the Massachusetts Bay outfall and in close proximity to Boston Harbor, including NF02, NF04, NF05, NF07, NF08, NF09, NF0, NF2, NF3, NF4, NF5, NF6, NF7, NF8, NF9, NF20, NF2, NF22, NF23, NF24, FF0, FF2, and FF3. Farfield refers to regional stations located far away from the outfall and Boston Harbor, i.e., FF0A, FF04, FF05, FF06, FF07, FF09, FF, and FF4. Transition Area refers to nearfield stations located close to Boston Harbor, i.e., FF0, FF2, and FF3. Outfall refers to the Massachusetts Bay outfall. Anthropogenic refers to analytes that are generated or enriched in the environment by human activity. They are functionally defined for principal components analysis (PCA) as TPAH, TPCB, TDDT, TCHLOR, TLAB, and CPERF. In addition, they include metals such as Al, Cd, Cr, Cu, Fe, Pb, Hg, Ni, Ag and Zn. All of these can be enriched by anthropogenic activities. However, Al and Fe are crustal metals that do not typically spike unless there is a nearby metallurgical industry (e.g., steel mill or aluminum smelter). Under normal circumstances, Al and Fe can be used as reference values for comparing the metal composition of samples collected at different locations. Percent Fines sum of percent silt and clay Total PAH (also referred to as TPAH) sum of concentrations of all PAH compounds listed in Table 0 of the benthic monitoring CW/QAPP (Williams et al., 2005), excluding Benzothiozole Total PCB (also referred to as TPCB) sum of concentrations of all PCB congeners listed in Table 0 of the benthic monitoring CW/QAPP (Williams et al., 2005) Total DDT (also referred to as TDDT) sum of concentrations of the six DDT, DDE, and DDD compounds listed in Table 0 of the benthic monitoring CW/QAPP (Williams et al., 2005) Total CHLOR (also referred to as TCHLOR) sum of concentrations of cis-chlordane, Heptachlor, Heptachlorepoxide, and trans-nonachlor Total LAB (also referred to as TLAB) sum of concentrations of C 0 C 4 LABs listed in Table 0 of the benthic monitoring CW/QAPP (Williams et al., 2005) CPERF refers to the sewage tracer Clostridium perfringens. Station Mean Average of all station replicates. Laboratory replicates were first averaged to determine a single value for a given replicate prior to calculation of station means. Station means were determined for each parameter within a given sampling year. Station mean values were used in the chemistry correlation analyses to determine the correspondence within bulk sediment properties and against contaminants in the nearfield and farfield areas. Station Mean Average of data for a given station over the baseline period, sampled during August surveys only. Each field sample replicate was treated as an individual sample. station mean values were determined for each station and parameter, and were compared to post-discharge (200) data to evaluate changes in the system (i.e., spatial, temporal). B-

12 For total contaminant calculations (e.g., Total PAH), a value of 0.0 was assigned to individual analytes that were not detected. Excluded Data The following data were excluded from the data analyses: FF08 data were omitted because this station was only sampled in 992, and was also distinctly different compared to other farfield stations (e.g., different habitat, much deeper water); similarly stations NF0, NF03, NF06, and NF were also excluded as they were only sampled in 992; FF0 data from 992 to993 were omitted from the regional range plots because the station location changed in 994 (hereafter referred to as FF0A) to a location approximately 0 km away, and in shallower water. Therefore, data for FF0A shown on the regional range plots includes data from 994 to 2002 only. FF0 ( ) data were included in the PCA, but qualified to indicate the change in station location; The range plot analyses showed that the following data were unusually high compared to baseline and other post-diversion data. These data were excluded from the correlation analyses. Total PCB data for NF07 in 2002; Total DDT data for NF2 in 200; Copper data for NF4 in 200; and Lead data for NF5 in These unusually high values appear to be associated with analytical interferences, random spikes, or unknown contamination, as contaminant values generally returned to baseline in subsequent sampling surveys. Data Analyses Sediment data were evaluated using box plots, ternary plots, range plots, and XY scatter plots to characterize the sediments, evaluate spatial and temporal trends, and assess changes in sediment quality that may have resulted from diversion of effluent discharge to the Massachusetts Bay outfall. Data graphics include: Box plots were used to visualize the data distribution, and identify points with extreme values (i.e., outliers). The ends of the box represent the 25 th and 75 th quartiles, and the line across the middle represents the median value. The lines are whiskers that extend from the ends of the box to the outermost data point that falls within the distances computed (a distance of.5 times the interquartile range, difference between 25 th and 75 th quartiles. Box plots were prepared using JMP (The Statistical Discovery Software). Ternary plots were used to visualize the grain size data, as percentages of gravel + sand, silt, and clay. Ternary plots were also prepared using JMP. Range plots were used to evaluate spatial and temporal trends between baseline and postdiversion data. To demonstrate this, the baseline range (i.e., minimum and maximum concentration over the baseline period) and mean (i.e., average concentration, by parameter and station, over the baseline period) values were determined, by station, for bulk sediment properties, C. perfringens, and contaminant parameters. ( ) data were then compared to the baseline range and mean values for each regional station to evaluate how the post-diversion data fit in with our understanding of the baseline system. Nearfield stations were presented as a function of distance from the western end of diffuser #55. Offshore stations B-2

13 were sorted as a function of their north to south location relative to the new outfall. Range plots were prepared using Microsoft Excel XY scatter plots were used to visualize the correspondence between the sediment data. Scatter plots were prepared using Microsoft Excel Sediment data were also evaluated by using statistical tests, including Tukey-Kramer and Pearson pairwise correlation analyses. Prior to statistical evaluations, the sediment data were checked for normality with the Shapiro-Wilk test, and where appropriate the data used in the statistical tests were logtransformed (i.e., C. perfringens, total PAH, total PCB, total DDT, total LAB, cadmium, chromium, copper, lead, mercury, silver and zinc). Tukey-Kramer was used to test system-wide and station-specific differences in group means, that is baseline and post-diversion means. Output from the test is a comparison circles plot, which is a visual representation of group mean comparisons. Circles for means that are significantly different (at the 95% confidence level) either do not intersect or intersect slightly so that the outside angle of intersection is less than 90 degrees. If the circles intersect by an angle of more than 90 degrees or if they are nested, the means are not significantly different at the 95% confidence level. The relationship between sediment variables was determined using Pearson pair-wise correlation analyses. The Pearson product-moment correlation coefficient (r) measures the degree to which two variables have a linear relationship if the variables have normal distributions. Values near indicate that the two variables have a strong positive correlation, values near - indicate that the two variables have a strong negative correlation, and values near 0 indicate that the two variables are unrelated. Strong correlation coefficients do not necessarily indicate a direct dependence of the variables. B-3
