This project centers around the Strategic Petroleum Site (SPR) known as the West Hackberry salt dome which located in southwestern Louisiana, and which is designed to store 241 million barrels of crude oil. Oil storage caverns are formed by injecting water into salt deposits, and pumping out the resulting brine. Studies described in this report were designed as follow-on studies to three months of pre-discharge characterization work, and include data collected during the first year of brine leaching operations. The objectives were to: (1) characterize the environment in terms of physical, chemical and biological attributes; (2) determine if significant adverse changes in ecosystem productivity and stability of the biological community are occurring as a result of brine discharge; and (3) determine the magnitude of any change observed. Volume V contains appendices for the following: supporting data for estuarine hydrology and hydrography; supporting data analysis of discharge plume; supporting data for water and sediment chemistry; CTD/DO and pH profiles during biological monitoring; supporting data for nekton; and supporting data for data management.

Volume IV contains the following: bibliography; appendices for supporting data for physical oceanography, and summary of the physical oceanography along the western Louisiana coast.

The physical, chemical and biological attributes are described for: (1) a coastal marine environment centered about a Department of Energy Strategic Petroleum Reserve (SPR) brine disposal site located 11.4 km off the southwest coast of Louisiana; and (2) the lower Calcasieu and Sabine estuarine systems that provide leach waters for the SPR project. During the study period, the daily discharge averaged 529,000 barrels of 216 0/00 brine, representing a loading of 18,000 metric tons of salt per day. The objective of this study are: (1) characterize the environment in terms of physical, chemical and biological attributes; (2) determine if significant adverse changes in ecosystem productivity and stability of the biological community are occurring as a result of brine discharge; and (3) determine the magnitude of any change observed. This report describes the methodology and significant results of the first year's monitoring effort of the West Hackberry brine disposal site. The investigative tasks, presented as separate sections, are: Physical Oceanography, Estuarine Hydrology and Hydrography, Analysis of Discharge Plume, Water and Sediment Quality, Special Pollutant Surveys, Benthos, Nekton, Phytoplankton, Zooplankton and Data Management.

Abstract: "A geologic reconnaissance map was prepared in the area of Vacherie Dome at a scale of 1:24,000. To do this, the available data were compiled, resistivity surveys were conducted, and reconnaissance field mapping took place. Then all the information was consolidated for the map preparation."

The following report summarizes the conclusions and what's been done on the work on the Quaternary geological studies of Rayburn's Salt Dome, North Louisiana Salt Dome Basin.

Abstract: "The Institute for Environmental Studies at Louisiana State University conducted research into the potential use of Louisiana salt domes for disposal of nuclear waste material. Topical reports generated in the 1981 and 1982 related to Vacherie and Rayburn's domes are compiled and presented, which address palynological studies, tiltmeter monitoring, precise releveling, saline springs, and surface hydrology. The latter two are basically a compilation of references related o these topics."

The following report provides a compilation of appendices focused on the geological investigations of Vacherie salt dome in the north Louisiana Salt Dome Basin.

Abstract: The report summarizes progress on geologic and hydrologic research related to the disposal of radioactive wastes. The research is described according to whether it is related most directly to (1) high-level and transuranic wastes; (2) low-level wastes, or (3) uranium mill tailings. Included is research applicable to the identification and geohydrologic characterization of waste-disposal sites, to investigations of specific sites where wastes have been stored, and to studies of regions or environments where waste-disposal sites might be located. A significant part of the activity is concerned with techniques and methods for characterizing disposal sites and studies of geologic and hydrologic processes related to the transport and (or) retention of waste radionuclides.

Purpose and Scope: The principal objective of this project was to measure the backwater and discharge distribution for multiple bridges. These data have been used to determine if the methods developed by Schneider and others (1976) for single-opening highway crossings could be applied to multiple bridges. In addition, the method developed by Tracey and Carter (1955) and Cragwall (1958) was modified to use the procedure proposed by Schneider and others (1976) to calculate friction losses in the approach reach. This modified procedure was then also tested.

From introduction: This report presents the application of FESWMS to the Pearl River and illustrates the usefulness of the two-dimensional model in analyzing steady-state flow with both lateral and longitudinal variations.

From purpose and scope: The purposes of the investigation were to develop from available information (1) a description of the regional aquifer system serving as a public supply in the Capital Area Ground Water Conservation Commission district, the Florida Parishes of southwestern Mississippi; and (2) to discuss potential alternative sources of freshwater.

From abstract: This report is the third in a series of reports describing the regional geohydrology of the northern Louisiana salt-dome basin. The Wilcox-Carrizo and Sparta aquifers are the principal Tertiary aquifers of regional extent in the basin. The Wilcox-Carrizo aquifer is not affected by regional water-level declines, as no large pumping centers have been developed. Water-level fluctuations in wells are mostly seasonal. As shown by the hydrographs of seven wells, the seasonal fluctuations are generally less than 10 feet annually. Therefore, the potentiometric surface of the Wilcox-Carrizo aquifer in northwestern Louisiana is shown by contours using data collected from 1960-80.
