Problem De~nition/Background Oso Bay (TCEQ segment 2485), a small (-- 7.2 square miles) and shallow (<1 meter) secondary bay off Corpus Christi Bay receives freshwater from Oso Creek (TCEQ Segment 2485a). The Oso Watershed drains an area of approximately 255 squaze miles. The Texas Commission on Environmental Quality (TCEQ) lists 19 permitted industrial wastewater discharges into Oso Bay. Corpus Christi is experiencing major growth into the Oso Watershed, resulting in significant runoff from subdivisions within and adjacent to the watershed. The upper portion of the watershed is dominated by fazming activities, resulting insignificant agricultural runoff into the Oso Creek. Because of the watershed's small size, the large number of permitted industrial discharge, and the large volume of both municipal and agricultural runoff (especially following heavy rains); Oso Creek and Oso Bay are consistently on the TCEQ's 303(d) list of impaired water bodies. Recently both Oso Creek and Oso Bay have been selected for implementation of a Total Maximum Daily Load plan due to high concentrations of bacteria (enteroccus). The Center for Water Supply Studies (CWSS) at Texas A&M University-Corpus Christi and the Texas A&M University-Corpus Christi Environmental Microbiology Laboratory (TAMUCCEML) completed an investigation funded by the Texas Commission on Environmental Quality (TCEQ) to: acquire additional water quality measurements; develop a numerical model of bacteria loading in Oso Bay and Oso Creek; and determine the total allowable daily load, the actual daily load, and the required load reduction to meet the water quality objectives of these segments. The final report of this investigation concluded that: • Oso Bay actually meets current water quality objective with the exception of TCEQ monitoring station 13441 which was found to be unrepresentative of ambient conditions in Oso Bay; • Oso Creek bacteria loading was the result of two processes, dry weather loading and runoff loading; • Dry weather loading in Oso Creek (although small in magnitude) must be eliminated to meet water quality objectives (geometric mean standard) for the segment; • Sources of dry weather loading of bacteria may include ground-water contributions to the creek. As a result of this report and the data gathered during the investigation, the water quality criteria for TCEQ monitoring site 13441 have been modified from contact recreation to non-contact recreation. This has placed Oso Bay into compliance with water quality requirement set by the TCEQ and completed part of the TMDL implementation. The remaining part of the TMDL implementation concerns Oso Creek. Initial indications Page 1 of 29 from the TCEQ are that the City of Corpus Christi will be responsible for the reduction of bacteria loads from wet and dry weather loads within the city limits. Because of the broad reaching implications for a number of entities (agriculture, municipalities, private residences, etc.) in managing this issue several interconnected projects have been funded by the Coastal Bend Bays and Estuary Program (CBBEP) and the Texas State Soil and Water Conservation Board to determine the source of the bacteria (human, wildlife, domesticated animals, OSS, WWTP, agricultural practices). These projects include soil sampling, sediment sampling, and ground water sampling as well as continued monitoring for 3-4 years. Ground-water monitoring wells must be installed at a number of sites along Oso Bay and Oso Creek (Figure 1)to collect relevant data that could either confirm or reject ground- water as a source of bacteria loading during dry weather. These wells would be installed to a maximum depth of 35' depending on location and depth to water level. They would be monitored over the course of the investigation for bacteria (enterococcus), temperature, water level, and salinity. The wells would be made available for sampling of other components by other entities as necessary. These scientific investigations will provide critical data that will guide the TCEQ in the implementation of the bacteria TMDL so that management strategies are applied effectively. From the previous study it was shown that elimination of the dry weather loading brought all the stations close to meeting the water quality objective for bacteria. Focusing on this dry weather bacteria source is the most cost effective approach for the City of Corpus Christi to follow in trying to meet the State's water quality goals. Other goals of this project are to improve our understanding of: 1) freshwater interactions with, impacts on, and needs of the bay system, 2) constituent loadings and transport pathways, and 3) biological and ecological effects on the bay system; thereby allowing more effective resource management. Site selection criteria (from our project plan) for the ground-water monitoring wells Sampling locations will consist of two ground-water monitoring wells screened at different depth intervals, an existing (TCEQ) surface water monitoring location (where possible), and a sveambed "piezometer" designed to allow multiple (4) zones of interchange to allow temperature measurements through the sveambed. The number of sampling locations will be constrained by well installation costs, but should total between 15 and 20 locations Ground-water monitoring well installation procedure: Two wells will be installed by a licensed water well driller at each location. One well will be installed in the fvst penevated fully saturated sand or to a depth of 20 feet, whichever is shallower, and completed with five feet of 2 inch 0.01 inch slot well screen and two inch casing [o the surface. The second well will be completed in the next fully saturated sand that is at least ten feet deeper or to a depth of 30 feet, whichever is shallower, and completed with five feet of 2 inch Page 2 of 29 0.01 inch slot well screen and two inch casing to [he surface. A single well slug test will be performed on each well to determine hydraulic conductivity. All wells will be instrumented with a temperature data logger, two wells will be instrumented with water level recording devices, and one well will be instrumented with a combination water level and specific conductivity recording device. Our current budget does not include a contingency for installation fees, etc. other than actual well installation and completion and we are not a "for-profit" entity. We embark on these investigations as both a public service and a scholarly activity to further our understanding of science. There are hundreds of bacteria impaired water segments in Texas and this investigation will be able to bring a better understanding to the sources of the bacteria and a more focused approach to the management of the impairment.
