Abstract:
Fish and macroinvertebrate communities near major wastewater outfalls in southern California have been monitored for over twenty years. The objective of the monitoring is to determine the impact of the wastewater discharge on these communities. Since marine communities are variable both in space and time, the determination of impact is usually achieved by comparing conditions in the vicinity of the outfalls to conditions in "reference" areas, that is, areas believed to be free from impacts from human activities. On three occasions SCCWRP has conducted surveys of sediment characteristics, contaminant levels, and biological conditions on the southern California mainland shelf in order to provide reference values for comparison to data collected from areas affected by wastewater discharge. The first survey was conducted in 1977 (Word and Mearns 1979). Seventy benthic grab samples and 53 trawl samples were taken from 71 stations distributed at approximately 1 0-kilometer intervals between Point Conception and the Mexican Border. Samples were taken at a depth of approximately 60 meters because most of the major outfalls discharge at this depth. In 1985, 13 of the original 71 stations were reoccupied (Thompson et al. 1987). Samples were taken at 30, 60 and 1 50 meters in order to provide data for the range of depths sampled in the monitoring programs. The third SCCWRP reference survey was conducted in 1990.
Purpose:
This report contains the results of the 1990 survey. It also updates the preceding reports, with several differences. New in the 1990 Reference Survey are estimates of reference values for near-bottom salinity; total nitrogen, iron, and manganese ; and nine polynuclear aromatic hydrocarbon (PAHs) compounds in sediments. Variables reported in previous surveys that are not included in this report are estimates for contaminants in tissues, concentrations of lindane, hexachlorobenzene, o,p' DDD, lipids, total volatile solids (TVS), and several PAH compounds in sediments. The 1990 survey was designed to update the information collected in the 1977 and 1985 surveys.
Supplemental_Information:
Sediment-grain size (% sand, % silt, % clay), total organic carbon (TOC), and total nitrogen (TN) were measured at each station. Details of analysis are included in Lab methods.. Total volatile solids (TVS) was not measured in this survey. Regressions presented in the 1985 survey report can be used to calculate total volatile solids values from the TOC values. Nine trace metals were measured in each sample: silver (Ag), cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), zinc (Zn), iron (Fe), and manganese (Mn). Fe and Mn were not measured in previous surveys. Detection limits are listed on Table 1 and details of analysis are included in Appendix 2. Seven chlorinated hydrocarbon contaminants were measured at each station, five DDT isomers (o,p'-DDE, p,p'-DDE, p,p'-DDD, o,p'-DDT, p,p'-DDT), and two PCB compounds (Aroclor 1242 and Aroclor 1254). Detection limits are listed in Table 1 and details of analysis are included in Appendix 2. The five DDT isomers analyzed in this survey are a reduction from the six isomers measured in the 1 977 and 1 985 surveys; o,p'-DDD was not measured in this survey. Thirty polynuclear aromatic hydrocarbon (PAH) compounds were measured in sediments from each site. These compounds and their detection limits are listed in Table 1. The 30 compounds are somewhat different from the 28 compounds measured in the 1985 survey. However, some individual PAH compounds were measured in both surveys (Table 1). Polynuclear aromatic hydrocarbons were not measured in 1977. Given the differences in the number of DDT isomers and PAH compounds measured in the 1985 and 1 990 surveys, total DDTs and total PAHs reported in each survey should not be directly compared.

Methodology_Description:
Veen grab sampler. For sediment characteristics and contaminants, two subsamples were taken from the grab sampler: one for grain-size, organic material, and trace metals, and the other for trace organic contaminants. The sub-samples were collected from the surface 2 cm of the grab sample with an open-barreled syringe, 26 mm in diameter. The samples were composited, and immediately frozen.

Methodology_Description:
A. Total Organic Carbon and Nitrogen Elemental analyses (total organic carbon-TOC, total nitrogen-TN) were carried out on sediments by high temperature (flash) combustion using a Carlo Erba EAl 108 elemental analyzer. The sediments were ground with a mortar and pestle, weighed into silver combustion boats, treated for carbonate removal by a modification of the vapor acidification technique of Hedges and Stern (1984), and heated to drive off excess HCI and water. The carbonate-free sediments were then wrapped in tin combustion boats and analyzed on the Carlo Erba elemental analyzer. Data were acquired with a Carlo Erba EAGER 100 data system which utilizes an IBM-compatible microcomputer. The instrument was calibrated daily with acetanilide. The precision of the sediment analyses for TOC and TN are estimated at < 2% and < 5%, respectively, based on replicate determinations of carbonate-free sediments and sludges. Analysis of acetanilide showed that the instrument yields results within 0.5, 0.05, and 3.3% of the actual amounts of carbon, nitrogen and hydrogen, respectively. Analysis of National Research Council of Canada standard reference sediments, PACS-1, for total carbon yielded results that agreed with the certified value to within 5.7%. All concentrations presented here are relative to total sediment weight (i.e. including carbonate carbon). B. Sediment Grain Size Analysis The sample was thoroughly homogenized by stirring or shaking. Approximately 20-40 g was sub-sampled and placed in a 1 000 ml beaker or flask. For sandy sediments, more was used (~40 g): for finer sediments less was used (~20 g). Twenty-five ml 10% hydrogen peroxide was added to digest organic material. When frothing ceased, an additional 1 0 ml hydrogen peroxide was added and the sample was boiled to remove any excess hydrogen peroxide. Care was taken to avoid boiling over the sample. The sample was separated into sand and silt/clay fractions by wet sieving through a 63 urn stainless steel sieve. The silt/clay fraction that passed through the sieve was collected and the sand fraction was retained on the sieve. The bottom of the sieve was wrapped with foil to prevent loss of sample, and the sample was dried at 40-500C. The silt/clay fraction was transferred to a 1 000 ml graduated cylinder and allowed to stand until most of the particles had settled (over night). The water was decanted into 500 ml polypropylene bottles and centrifuged for 20 minutes at 1000 RPM. The clear water from the centrifuged bottles was siphoned off and the remaining fine residue was washed back into the graduated cylinder. Twenty-five ml of 1 % Calgon solution was added to the silt/clay fraction to prevent flocculation of the sediment particles. The sample was then adjusted to 1 000 ml with distilled H20 and observed for flocculation. The sample was vigorously mixed and a 25 ml sample was withdrawn from a depth of 20 cm, 20 seconds after the stirring was stopped (silt fraction). The sample and pipette were rinsed with distilled water into the aluminum weighing dish. A 25 ml sample was taken from a depth of 5 cm at the times tabulated by Plumb (1981) and transferred to a pre-weighed aluminum dish (clay fraction). Twenty-five mIs of 1% Calgon solution was also dried in a pre-weighed dish to act as a correction factor in the pipette analysis calculations. After the sand fraction was dried, a sieve was placed over a smooth sheet of paper. A 2.5 cm soft bristle paint brush was used to brush the particles across the screen until no fine particles continued to pass through the sieve. The fine particles that passed through the 63 um sieve were dried in a pre-weighed aluminum dish and the dried weight added to the silt fraction. The sieve was inverted and the screen brushed to remove additional sand particles caught in the sieve. The particles were added to the sand dish. Aluminum dishes containing the samples were dried at SOOC and weighed to the nearest 0.0001 g. Calculations were as follows: Silt weight = ([net wt. sample - Calgon correction factor] X 40) + Additional silt Clay weight = (net wt. sample - Calgon correction factor) X 40 Calgon correction factor = (net weight of 25 ml Calgon) X .025 (ml of Calgon in sample) C. Trace Metals After intercalibration studies using standard reference materials were done, trace metal analyses were subcontracted to Global Geochemistry Corporation, Canoga Park, California. Sediments were analyzed for silver, cadmium, chromium, copper, nickel, lead, zinc, iron and manganese. Sample digestion was done using EPA SW 846 3050 procedure. Wet sediment was digested in nitric acid and hydrogen peroxide. The digestate was then refluxed with either nitric acid or hydrochloric acid and then diluted to a volume of 50 ml. A separate sample was also taken for determination of moisture. An analytical blank was prepared and treated as a sample throughout the digestion procedure. Samples were analyzed on an inductively coupled plasma emission spectrometer, a Baird simultaneous PST installed with 27 element channels. The concentrations of the metals were determined by comparison with known standards. Where interelement interference was observed, corrections were made accordingly, i.e., iron on cadmium, copper, chromium and lead; and aluminum on cadmium and lead. Post digestion spikes of each sample were done and the recoveries were used to correct all data affected by the sample matrix, including pre-digestion spikes. D. Trace Organics Analysis of polynuclear aromatic hydrocarbons (PAHs) and chlorinated hydrocarbons (CHCs) was also subcontracted to Global Geochemistry Corporation. Extraction and clean up of the sediments were carried out according to modified SCCRWP methods (Eganhouse et al. 1990). The frozen samples were thawed and homogenized. Wet sediment was extracted three times with methylene chloride by sonication for 30 minutes. The combined extracts were then concentrated to a small volume. Clean up was done using a silica gel column. A fraction corresponding to PAHs and CHCs was isolated and taken up in hexane. The PAHs were analyzed on an Incos 50 GC-MS using a modified EPA 8270 method. The CHCs were analyzed on a Varian 3700 gas chromatograph equipped with an electron capture detector. The DDT compounds (o,p'-DDE, p,p'-DDE, o,p'-DDT and p,p'DDT) and the Arochlors (1242 and 1254) were quantified by the internal standard method using PCB congener 207 (Ballschmiter and Zell 1980). One peak was used for quantitation of 1242 and two peaks for 1254 as described in Eganhouse etal. (1991).
