## s) USGS used spatially and temporally matched d ata sets from Cutter and Cutter ( 2004) and Doblin et al., ( 2006) to determine selenium water column concentrations and particulate concentrations for points along seaward transects, and data from Lucus and Stewart (2007) to determine concentrations for points along landward transects (USGS, 2010). The se concentrations were used to calculate partitioning coefficient s (K d 

## s) for points along four seaward and four landward transect s (USGS, 2010). Seaward and Focused Seaward Transects The sa linity, selenium water concentrations, selenium particulate concentrations and K d 

## values for points along each of the seaward and focused seaward transects are included in Tables 1 through 8. For each set of K d 

## values (i.e., for each transect), the minimum, maximum, mean, 25 th 

## percentile, 50th 

## percentile (median) and 75 th 

## percentile values have been determined , as well as the standard deviation and the 95 th 

## percentile confidence level values. All four seaward transects reflect wet or above average flow conditions. Each of the four seaward transects has between 13 and 21 K d 

## values, and each has one or two outliers (i.e., an exceptionally high value). For each seaward and focused seaward transect, the mean , 75 th

## , 50 th 

## (median), and 25 th 

## percentile values are relatively close in value compared to the total range in values, indicating that most of the K d 

## values along each transect are within a reasonable range of each other
. Since transect data were not available for dry or critically dry flow conditions ( usually reflecting higher K d 

## values ), 75 th 

## percentile K d 

## values are us ed in the modeling to reflect a broad range of conditions
. The data in Tables 1 through 4 and Figures 1 through 4 for each seaward transect, and in Tables 5 through 8 and Figures 5 through 8 for each focused seaward transect show that the range of K d 

## values narrows in the geographic area in and around Carquinez Strait (the area of the focused seaward transects)
. Most of the very high K d 

## values ( 9 of 10 of the K d 

## values greater than 10,000) were found close to the ocean interface where longer residenc e times can result in phytoplankton stripping selenium from the water column, raising K d 

## values. Since most of the clam concentration data collected are from the areas in and around Carq uinez Strait and Suisun Bay, areas where important species are locate d and where selenium discharges are occurring, bioaccumulation analyses are focused on these cr itical areas of the estuary. Figure A is the frequency distribution of all seaward K d 

## values, and Figure B is the frequency distribution of all focused seaward K d 

## values (i.e., the K d 

## values for data points in and around Carquinez Strait). The range of K d 

## values noticeably narrows in and around Carquinez Strait
.

## Landward Transects Selenium water concentrations, selenium particulate concentrations and K d 

## values for points along each of the land ward transects are included in Tables 9 through 12 . For each set of K d 

## values (i.e., for each transect), the minimum, maximum, mean, 25 th 

## percentile, 50 th 

## percentile (median) and 75 th 

## percentile values have been determined, as well as the standard deviation and 95 th 

## percentile confidence level values. Two of the four lan dward transects reflect above normal flow conditions and two reflect below normal flow conditions. Data in Tables 8 through 12 and in Figures 8 through 12 for each landward transect show that e ach of the four landward transects has between 11 and 12 values, and only one (October 2003) appears to have an outlier value (the only landward K d 

## value greater than 10,000) . For each landward transect, the mean , 75 th

## , 50 th 

## (median), and 25 th 

## percentile values are relatively close in value, indicating that most of the K d 

## values along each transect are within a reasonable range of each other. Since data are not available for dry or critically dry flow conditions (usually reflecting higher K d 

## values), 75 th 

## percentile K d 

## values were used in the modeling to reflect a broad range of conditions. D ata for three of the four landward tran sects were collected during high flow periods (winter months) . Freshwater dominated many of transect stations in each of the January 2003, April 2 003, and January 2004 transects (salinities less than 1 ppt)
. The K d 

## values are generally more consistent and slightly lower in these transects, than in the seaward transects. The October 2003 transect was the only transect that refl ected a low flow period, with salinities of 10 to 12 ppt near Benicia, the most seaward station for the landward transects. During high flow periods, dilution of Delta water with particles from the Sacramento River may contribute to the lower K d 

## values 1


## . Additional data from low flow periods during drier years may help to better understand the dynamics in low flow periods
. If only stations with salinities greater than 1 ppt are considered, the mean K d 

## is 395 5 and the 75 th 

## percentile is 4762 ; these values are similar to and within the range of the focused seaward mean and 75 th 

## percentile K d 

## values
. Figure C is the frequency distribution of all landward K d 

## values, and Figure D is the frequency distribution of all landward K d 

## values at stations with salinities greater than 1 ppt.

### Selenium particulate concentrations from the Sacramento River are lower than selenium particulate concentrations from the San Joaquin River, while flow volume from the Sacramento River into the Delta is much higher than that from the San Joaquin River.
