6 Prinled 011 R~ycred Paper c-«bio-sl/iowa.l 4/08/ INTRODUCTION Environmental Science & Engineering, Inc. (ESE) conducted two Definitive Static Acute Toxicity Test Sets utilizing Ceriodaphnia dubia and Pimephales promelas as the test species on samples collected from the Iowa Anny Ammunition Plant for the U.S. Anny Environmental Hygiene Agency, Aberdeen Proving Grounds, Maryland. The tests were conducted March 25-29, 1993, and followed EPA protocol number EPA/600/4-89/027. The criterion for effect was survival, but other adverse effects (when observed) were noted as well. Additionally, each sample was processed according to the Day 1 Procedures in the Methods for Aquatic Toxicity Identification Evaluation, Phase I Toxicity Characterization Procedures (EPA/600/3-88/034). According to this protocol, a complete Phase I Toxicity Identification Evaluation (TIE) was performed on all samples dem~~strating. significant toxicity at the 24-hour observation. 2.0 TEST PROCEDURES 2.1 TEST SUBSTANCES The effluent samples were shipped via overnight courier on March 24, 1993 by personnel of the U.S. Anny Environmental Hygiene Agency and the Lone Star Anny Ammunition Plant for the static acute toxicity tests. Test initiation began immediately upon receipt of the samples. Samples were received at ESE's St. Louis Missouri Aquatic Toxicology Laboratory on March 25, 1993 (Table 2-1). Copies of sample chain-of-custody records and test substance receipt log are found in Appendix A. Copies of the pick-up order/work order/delivery sheets are found in Appendix B. Dilution water was moderately hard laboratory reconstituted freshwater. additionally utilized as the control water. This water was 1

8 Pri nted on Recycled Paper c-ecbio-slriowa.j 4/08/ CERJODAPHNIA ACUTE TOXICITY TEST The tests were conducted in 100 ml glass beakers with 50 ml of test solution in each chamber. Test duration was 48 hours and conducted under static conditions at 20±2 C. The photoperiod was maintained at 16 hours light and 8 hours dark. The water quality measurements for the test period are found in Appendix C. Less than 24-hour old neonates were randomly added to test chambers with ten animals per replicate. Each concentration tested was replicated twice. Effluent was diluted with laboratory control water to prepare the desired concentration series, and laboratory controls were run concurrently. Animals were tested at 6.25, 12.5, 25, 50, and 100 percent effluent on a volume to volume basis. All quality control logbooks (i.e., meter calibration logs, Test Substance.. Receiving Log, etc.), reference toxicant test data, and raw data sheets are maintained at ESE's Midwest Regional Aquatic Toxicology LaboratoryI S1. Louis, Missouri. 2.3 PIMEPHALES PROMELAS ACUTE TOXICITY The test was conducted in l-iiter glass beakers with 400 ml of test solution in each chamber. Test duration was 96 hours ± 1 hour, and conducted under static conditions at 20±2 C. The photoperiod was maintained at 16 hours light and 8 hours dark. The water quality measurements for the test period are found in Appendix C. Fathead minnow larvae (4 days old) were randomly added to test chambers with ten animals per replicate. Each treatment tested was replicated twice. Laboratory controls were run concurrently. Animals were tested in 6.25, 12.5, 25, 50, and 100 percent effluent diluted with laboratory reconstituted freshwater 011 a volume to volume basis. All quality control logbooks (i.e., meter calibration logs, Test Substance Receiving Log, etc.) reference toxicant test data, and raw data sheets are maintained at ESE's St. Louis, Missouri Aquatic Toxicology Laboratory. 3

9 Printed on Recycled Paper c-ecbio-al/lowa.a 4/03 / TIE PROCEDURES (DAY 1) Immediately upon sample receipt, one liter of each effluent was sub-sampled for the Day I TIE procedures. Effluent samples were manipulated by taking 300 ml volumes of each effluent and adjusting the ph to 3 or II standard units (SU) utilizing sodium hydroxide (NaOH) or hydrochloric acid (Hfll), A 300 ml volume was also kept at the original ph (PH). Bench scale treatments were performed on effluent fractions including: Filtration through 1.0 ~m glass fiber filter; Aeration (air striping column); and CIS solid phase extraction (SPE) column. All treated fractions were returned to plio, covered and stored at 4 C overnight. 2.5 COMPLETION OF TIE PROCEDURES Phase I TIE procedures are completed if the 24-hour LC so indicates toxicity. Treated effluent fractions from the previous day are brought to test temperature and readjusted to ph. Fractions were then tested at 4, 2, 1, and 0.5 times the 24-hour LC so value for effluents demonstrating toxicity. Additional procedures were then performed on effluent samples including: Oxidant reduction utilizing sodium thiosulfate (N~S103); Complexing of metals through ethylenediaminetetraacetate ligand (EDTA) chelation; and Graduated ph adjusted of the effluent to 6.0, 7.0, and 8.0 SU, at the 24-hour LC so ' A baseline toxicity test was also set up to establish the second day toxicity of the sample. 2.6 QUALITY ASSURANCE A reference toxicant test using sodium dodecylsulfate (SDS) was conducted with neonate C. dubia. The static test was conducted for 48 hours at test concentrations of 0.5, 1.0, 2.5, 5.0, and 10.0 mg/l. A control treatment consisting of reconstituted freshwater was also run, Dilution water was laboratory reconstituted freshwater. Ceriodaphnia were 4

Less than 24-hour old Ceriodaphnia were exposed from March 2-4, Additionally, a reference toxicant test using sodium dodecylsulfate (SDS) was conducted with larval P. promelas. The static test was conducted for 48 hours at test concentrations of 1.0, 2.5, 5.0, 10.0, and 20.0 mg/l. A control treatment consisting of reconstituted freshwater was also run. Dilution water was laboratory reconstituted freshwater. P. promelas were tested in 1,000-mL glass beakers containing 750 ml of test solution. Ten animals were tested per test container. The test was conducted at 20±2 C. The 2 to 5-day old larvae were exposed from March 2-4, TEST RE..'iULTS 3.1 SAMPLE LOCATION The mortality results for this location are presented in Tables 3-1 and 3-2. location demonstrated no significant toxicity to the species tested..'j Overall this Ceriodaphnia Toxicity Testine Results C. dubia exhibited no acute toxicity to sample during the 48-hour exposure period. This is evidenced by 5 percent mortality in the 100 percent effluent treatment. No mortality was observed in any laboratory control replicates (see Table 3-1) Pimephales Promelas Toxicity Testine Results P. Promelas also exhibited no toxicity to sample Il-24 with a final 96-hour mortality of opercent in the 100 percent effluent treatment. No TRE procedures were performed. No mortality was observed in any laboratory control replicate (see Table 3-2). 5

A 96-hour LC so could not be determined due to lack of significant toxicity. Laboratory controls exhibited no acute toxicity in any.'~ replicates (see Table 3-4). 3.3 QUALITY ASSURANCE TOXICITY RESULTS Mortality of C. dubia during the 48-hour exposure to SDS is reported in Table 3-5. The 48-hour LC so for C. dubia using the Spearman Karber Method was 4.67 mg/l with 95 percent confidence limits of 3.76 to 5.78 mg/l. These values are within the normal range of values for SDS tests conducted at ESE. Mortality of P. promelas during the 48-hour exposure to SDS is reported in Table 3-6. The 48-hour LC so for P. promelas using the Logit Method was 3.74 mg/l with 95 percent confidence limits of 1.80 to 6.51 mg/l. These values are within the normal range of values for SDS tests conducted at ESE on this age group (24-48 hours old) of P. promelas, 4.0 DISCUSSION No complete TIE procedures were performed on samples and due to lack of toxicity based on mortality effects in both test species. 8
