Abstract:

A 27-year (1993-2020) monitoring dataset was designed to evaluate the impact of an industrial discharge facility in Lavaca Bay, Texas, USA. The discharge releases effluent from the Formosa Plastics Corporation (FPC), Texas, Point Comfort facility that primarily produces polyvinyl chloride, polyethylene and polypropylene resins and other plastic products. The diffuser was built in July 1993 and became operational on September 22, 1993. The Receiving Water Monitoring Program was established to meet the regulatory objectives of the Texas Commission on Environmental Quality (TCEQ, formerly the Texas Natural Resource Conservation Commission) and the U.S. Environmental Protection Agency (EPA) as outlined in TCEQ Wastewater Permit # 02436, EPA Permit # TX0085570. Monitoring trips began in May of 1993 and continue today (as of April 2022), but the current dataset ends April 2020. Fixed point, sampling was collected at 19 stations. Stations were set by general circulation patterns in Lavaca Bay, zone of initial dilution, and mixing zone descriptions. Distances A-, B-, C-, D-, and R- form rings around the diffuser with a total of 4 stations per ring, except for D-stations which only have 3. There are four replicate sample locations (1, 2, 3, and 4) on each distance ring. The dataset is large, containing 672,574 rows (each with a value), and 24 columns (2 for the value and qualifier, and 22 describing the sample location and type). Variable types include conventional chemistry, contaminant chemistry in water, sediment, porewater and tissues. Plankton, nekton, and benthos were measured to study biological responses to environmental stressor effects on the ecosystem health.

Methods:

Collection Methodology The methods reported here are a summarization of Freese and Nichols (2020) collection methods for chemical parameters and biological parameters. The Freese and Nichols (2020) annual report – Methods are found verbatim in Appendix D. Water Chemistry All water samples were collected with a non-contaminating submersible plastic pump lowered and raised through the water column offering vertically mixed samples (except those for metals analysis). Dissolved metals samples, except for mercury and selenium, were field filtered through a 0.45-micron (μm) filter cartridge. Water samples were stored in containers of ice until transported to a chemistry contractor. As a minimum 10 percent of sample stations per trip were triplicated for chemistry collections in water. Porewater Chemistry Sediments collected for porewater extraction were stored in 3.5-gallon plastic buckets and sealed to exclude air. PVC pressure chambers equipped with 5.0-μm polyester filters were used to extract porewater samples from sediment collections. Porewater was chilled to ≤4 degrees Celsius (°C) after extraction and treated with the proper preservative (if needed). A minimum of 10 percent of porewater samples were triplicated. Sediment Chemistry A stainless posthole digger was used to collect sediment samples. Sediment samples were then collected from the digger with a stainless-steel spoon, placed into airtight glass jars and stored at 2–4°C until delivered to the chemistry contractor. Acetone, Alconox, and deionized water was used to rinse the digger after sampling was completed at each station. A minimum of 10 percent of sediment samples were triplicated. Nekton/Epifauna Nekton/epifauna were collected with both a 3-meter otter trawl with ¼-inch mesh cod end and 150-foot by 8-foot, 6-panel, experimental gill nets with 2-, 3-, 4-, 5-, 6-, and 7-inch stretch mesh panels. The trawl was towed for 5 minutes at approximately 2 miles per hour. Distance traveled in each trawl was determined with a flow meter. Approximately 900–1,000 linear feet by 10-foot width were the area sampled by trawl. Trawl samples were preserved with 10 percent formalin. Gill nets were set overnight and collected the subsequent morning. Gill nets were used to capture larger species. Ichthyoplankton Ichthyoplankton were captured with an 18-inch-diameter, 7:1 length-to-mouth ratio tow net with throat-mounted flow meter and #505 mesh. Ichthyoplankton tows were made at all stations sampled by trawl and gill nets and towed obliquely over a 5-minute period. Ichthyoplankton samples were preserved in 10 percent formalin and transferred to 70 percent ethanol, plus glycerin after hardening. Phytoplankton Phytoplankton samples were collected with a non-contaminating submersible pump. 2 liters (L) of vertically mixed water were pumped into a clean container, Water was collected from the surface to a depth of 1 meter. A 1 percent concentration of acid Lugols solution was used to preserve all phytoplankton samples. The outfall location and stations B1, B2, B3, and B4 each represented one replicate sample for that location. At the reference stations (R1 through R4), four replicates were collected from four locations evenly spaced along a 200-foot radius from the station. Zooplankton A #20-(80-μm) mesh plankton net was used to collect zooplankton samples. Zooplankton sampling consisted of four replicates at each station. 48 L of water were collected from the surface with a clean bucket and measured after passing through a #20-(80-μm) mesh plankton net for each sample collection. A 1 percent concentration of acid Lugols solution was used to preserve all zooplankton samples. The outfall location and stations B1, B2, B3, and B4 each represented one replicate sample for that location. At the reference stations (R1 through R4), the four replicates were collected from four locations evenly spaced along a 200-foot radius from the station. Zooplankton samples were transported to the FNI laboratory and stored in the dark until analysis. Benthos Benthic samples were collecting using a 6-by-6-inch Ekman dredge (0.023 square meters [m2] of area collected for each sample). Each station had three Ekman dredge samples. Benthic samples were washed in-field with a #30 mesh screen then preserved in 10 percent formalin. Organisms were picked from the sample and then stored in 70 percent ethanol, plus glycerin. Laboratory Analysis Chemical Analysis Chemical analyses for all parameters were conducted by North Water District Laboratory Services, Inc. (NWDLS), The Woodlands, Texas. Conventional water, porewater and sediment chemistry and priority pollutant parameters were collected. Priority pollutants include total and dissolved metals, volatile organics, base neutrals, and pesticides and PCB’s. Method detection limits were also documented. The method detection limit (MDL) is defined as “the minimum concentration of a substance that can be measured and reported with 99% confidence that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix containing the analyte” (Environmental Protection Agency). Freese and Nichols, Inc. based quality assurance protocols on several U.S. Environmental Protection Agency analytical method standards in the efforts to measure the extent of environmental contamination in Lavaca Bay. All parameters collected with corresponding methods can be found in Appendix E. Phytoplankton (and Small Zooplankton) Phytoplankton samples were received in a 125-ml wide-mouth, clear glass bottle that contained 40 to 80 ml of sample. Samples were preserved with acid Lugols solution. 2.2 ml of thoroughly mixed sample solution was placed in a sedimentation chamber for analysis with an inverted microscope. The sample was set to settle for approximately 4 hours. Phytoplankton collected from years 1-15, minus year 5, was analyzed under 400X magnification. Years 16-27 was analyzed at a magnification of 1,000X. Phytoplankton and small zooplankton were identified to the lowest possible taxonomic unit. Zooplankton (and Large Phytoplankton) Zooplankton samples were received in a 125-ml wide-mouth, clear glass bottle that contained 40 to 80 ml of sample. Samples were preserved with acid Lugols solution. A wide-mouth plastic pipette was used to place 1 ml of thoroughly mixed sample solution into a 1 ml Sedgwick-Rafter cell for analysis with an inverted microscope. The volume of the sample was measured and used to calculate the total sample volume (ml). All zooplankton and large phytoplankton within a 1 ml sample were identified and counted at 100x magnification in the Sedgwick-Rafter cell. Zooplankton and large phytoplankton were identified to the lowest taxonomic unit possible. Benthos Preservatives in excess were washed off all benthic samples. A stereo dissecting microscope was used to pick out all invertebrates from a small aliquot of the sample placed in a pan with water. Picked invertebrates were placed into a labeled bottle filled with water or alcohol. Insects and crustaceans were stored in alcohol. Soft-bodied specimens (e.g., cnidaria, mollusks, annelids) were stored in water. Additional aliquots were examined until the sample was completed. Alcohol and formalin solutions included glycerin to prevent the drying out of specimens.
