This study was based on the sediment quality triad (SQT) approach. A stratified probabilistic sampling design was utilized to characterize the Chesapeake Bay system in terms of chemical contamination, sediment toxicity (Microtox, amphipod bioassay; sea urchin gamete bioassay; and P450 biomarker) and benthic infaunal community structure. The purpose was to define the extent and magnitude of toxicity and other biological effects associated with contaminants in the mainstem Chesapeake estuary and major western subestuaries. This file contains data measured in the Chesapeake Bay estuary system sampled in 1998, 1999, and 2001. Samples were collected for sediment analyses.
Specific objectives of the study were to: (1) Describe the levels and spatial distribution of contaminants in the Chesapeake Bay and western subestuaries; (2) Describe the incidence, severity and spatial extent of contamination, toxicity, and characteristics of the benthic infaunal community; (3) Describe the study results in relation to known or suspected sources of contamination; (4) Describe statistical relationships between levels of contaminants and adverse biological effects, and identify chemicals of concern in terms of regional environmental quality and adverse biological effects; (5) Compare environmental conditions within sub-areas of Chesapeake Bay and compare estimates of toxicity in Chesapeake Bay with those in other estuaries based on comparable data; (6) Assess benthic community composition in relation to habitat characteristics and the influence of contamination on those communities.The dataset objective is to report information about chemical residues in sediment, sediment toxicity, and benthic infauna characteristics of the system.
The partners in the Chesapeake Bay Mainstem Estuary Project were: (1) National Oceanographic and Atmospheric Administration (NOAA); (2) EPA Region III. The National Oceanographic and Atmospheric Administration (NOAA) was responsible for collection, final assembly and review of all data.

Accuracy
MEASUREMENT QUALITY OBJECTIVESSite location - Sampling sites were located by GPS with a manufacturer reported position accuracy of better than 3 meters in DGPS mode. Coordinates are expressed in units to the nearest 0.0001 decimal degrees. An acceptable tolerance goal for siting was that the sampling location be established within 0.2nm (+/- 120ft) of the given coordinates. In the event the vessel could not navigate to the site (i.e., too shallow) or the bottom type was not appropriate (i.e., rock or shellfish bed) then the first alternate site was substituted. In the event the first alternate could not be sampled then the second alternate site was sampled. Organic and Inorganic Contaminants - The measurement quality objectives of the Chesapeake Bay Project specify accuracy and precision requirements of 30% for organic analytes and 15% for inorganic analytes in sediment samples. Link to Quality Assurance Project Plan (http://ccma.nos.noaa.gov/about/coast/nsandt/)Water column measurements - Water column monitoring instrumentation was calibrated based on manufacturer's recommendations (YSI Corporation). Depth was recorded from the vessel fathometer.Benthic taxonomy-The minimum acceptable sorting efficiency was 95%. The minimum acceptable taxonomic efficiency was 95%. All chemical contaminant values have been rounded to three significant digits. To accommodate the wide range of values, all concentration values have been formatted to the thousandth unit (0.001). The actual precision is as listed below.Metals, variable ug/g; Butlytins 0.01 ng Sn/g;PAHs 0.1 ng/g;PCBs 0.01 ng/g;Pesticides 0.01 ng/g;

DATA QUALITY ASSURANCE PROCEDURESSite location - Handheld GPS units were compared daily with vessel GPS units. Organic and Inorganic Contaminants - QA procedures include blanks, spiked samples, and standard reference materials with each batch of samples. Any batch failing to meet the specifications would be reanalyzed or rejected. Link to Quality Assurance Project Plan (http://ccma.nos.noaa.gov/about/coast/nsandt/) Water Column measurements - Fields are arranged as follows:Indicator; QA sample type or measurement; Data generated for measurement qualityDO; Water-saturated air calibration; Difference between probe value and saturation levelSalinity; Seawater standard; Difference between probe measurement and standard valueSpecific Conductance; Seawater standard; Difference between probe measurement and standard valueTemperature; Thermometer; +/- 1CBenthic taxonomy-At a minimum, 10 percent of all samples were resorted and recounted on a regular basis. Ten percent of samples were randomly selected and re-identified. A voucher collection composed of representative individuals of each species encountered in the project was accumulated and retained.ACTUAL MEASUREMENT QUALITYWater column measurements - Fields are arranged as follows:Measurement; Units; Expressed to NearestDO; mg/L; 0.1Salinity; ppt; 0.01Specific Conductance; mS/cm; 1Depth; Meters; 0.5Temperature; C; 0.1

NAME OF DERIVED VALUES Chemicals with similar structural properties were summed and reported as "Totals" in addition to their individual measured concentrations. The components of these totals are as follows:Total DDT = sum of concentrations of ortho and para forms of parent and metabolites 2,4'DDE; 4,4'DDE; 2,4'DDD; 4,4'DDD; 2,4'DDT and 4,4'DDT.Total Chlordane = sum of concentrations of four compounds alpha-chlordane, trans-nonachlor, heptachlor, heptachlorepoxide.Total Dieldrin = sum of concentrations of two compounds aldrin and dieldrin.Total Butyl tin = sum of concentrations of parent compound and metabolites monobutyltin, dibutyltin, tributyltin, tetrabutyltin [concentrations are in terms of tin].Total PCB = the sum of the concentrations of eighteen congeners and/or co-eluting pairs of congeners: PCB8/5, PCB18/17, PCB28, PCB44, PCB52, PCB66, PCB10190, PCB105, PCB118, PCB128, PCB138/160, PCB153/132, PCB170/190, PCB180, PCB187, PCB195/208, PCB206, and PCB209.Total low molecular weight (lmw) PAHs = sum of concentrations of twelve 2- and 3-ring PAH compounds: naphthalene, 2-methylnaphthalene, 1-methylnaphthalene, biphenyl, 2,6-dimethylnaphthalene, acenaphthene, acenaphthylene, 1,6,7-trimehtylnaphthalene, fluorine, phenanthrene, 1-methylphenanthrene, and anthracene.Total high molecular weight (hmw) PAHs = sum of concentrations of twelve 4-and more-ring PAH compounds: fluoranthene, pyrene, benz[a]anthracene, chrysene, benzo[b]fluorantene, benzo[k]fluoranthene, benzo[e]pyrene, benzo[a]pyrene, perylene, dibenzathracene, indeno[1,2,3-cd]pyrene, and benzo[ahi]perylene.Total PAH = low molecular weight PAHs plus high molecular weight PAHs (sum of 24 PAH compound concentrations). Several numerical indices were chosen for analysis and interpretation of the macroinfaunal data. Infaunal abundance is reported as the total number of individuals per station and the total number of individuals per square meter (= density). Taxa richness is reported as the number of taxa represented in a given site location. Taxa diversity, which is often related to the ecological stability and environmental "quality" of the benthos, was estimated by the Shannon-Weiner Index.In order to quantify and compare the equitability in the fauna to the taxa diversity for a given area, Pielou's Evenness Index J' (Pielou, 1966) was calculated as J' = H'/lnS, where lnS = H'max, or the maximum possible diversity, when all taxa are represented by the same number of individuals; thus, J' = H' /H' max.Process Date Range is 1998-2001
