The Occurrence And Control Of Disinfection By-Products (Dbps) In Two Water Treatment Plants Utilizing The Same Source, Sam George Khoury

Theses and Dissertations

The influence of disinfection by-products (DBPs) on the operation and design of water treatment plants has been increasing since the early studies by Rook on trihalomethanes (THMs) (Stevens, 1977). Work conducted in the 1980s identified the existence of nonvolatile halogenated organics (non-THM organics), of which the majority produced by chlorination were haloacetic acids (HAAs), within the HAAs, dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) were the dominant members. Concern over potential health effect led the U.S. Environmental Protection Agency (USEPA) to set a maximum contaminant level (MCL) for total THMs and HAAs. The disinfectant/disinfection by-product rule (D-DBP Rule) currently proposed …

Performance Of Constraint-Handling Techniques Applied To A Genetic Algorithm-Based Watershed Management Model, Kwisun Park Yu

Civil & Environmental Engineering Theses & Dissertations

Wet detention ponds are a commonly used structural best management practice to reduce nonpoint source pollutant loading into receiving water bodies. Design of these ponds is typically carried out individually to meet a target total suspended solids (TSS) removal level. An improvement to this approach is to generate cost-effective pond configurations that meet system-wide targets for removal of pollutant loadings, corresponding to a specific build-out land use plan. The cost-effectiveness can be further improved through appropriate land use allocation planning conducted simultaneously with the design of detention ponds. Harrell and Ranjithan (2003) presented an evolutionary algorithm- (EA-) based modeling approach …

Sediment Nutrient Accumulation And Nutrient Availability In Two Tidal Freshwater Marshes Along The Mattaponi River, Virginia, Usa, Jennifer L. Morse, J. Patrick Megonigal, Mark R. Walbridge

Environmental Science and Management Faculty Publications and Presentations

Sediment deposition is the main mechanism of nutrient delivery to tidal freshwater marshes (TFMs). We quantified sediment nutrient accumulation in TFMs upstream and downstream of a proposed water withdrawal project on the Mattaponi River, Virginia. Our goal was to assess nutrient availability by comparing relative rates of carbon (C), nitrogen (N), and phosphorus (P) accumulated in sediments with the C, N, and P stoichiometries of surface soils and above ground plant tissues. Surface soil nutrient contents (0.60–0.92% N and 0.09–0.13% P) were low but within reported ranges for TFMs in the eastern US. In both marshes, soil nutrient pools and …

Groundwater Trends In The North Stirling Pallinup Sub-Region, Ruhi Ferdowsian, Lisa Crossing

Natural resources published reports

The South Coast Regional Initiative Planning Team (SCRIPT) has divided the South Coast region of Western Australia into six sub-regions. This publication describes the groundwater trends, risk of shallow watertables, and technical feasibility of salinity management in the agricultural district of the North Stirling Pallinup sub-region.

This sub-region encompasses the Stirling Range National Park, the North Stirling Basin to the north-east of the Park, and the middle and upper catchments of the Pallinup River. Almost 90% (500,000 ha) of the sub-region's alienated land has been cleared for agriculture, and salinity has been identified as an important issue.

Soil-landscape zones are …

Groundwater Trends In The Fitzgerald Biosphere Sub-Region, Adam Lillicrap

Natural resources published reports

The South Coast Regional Initiative Planning Team (SCRIPT) has divided the South Coast region into six sub-regions. The Fitzgerald Biosphere sub-region is located in the centre of the South Coast region of Western Australia (Figure 1). It is bounded by the Pallinup River to the east, Jerdacuttup River to the west, and includes the catchments of the Gairdner, Fitzgerald and Phillips Rivers. The sub-region encompasses the Fitzgerald Biosphere Reserve and just over half (730,000 ha) has been cleared for agriculture.

This publication describes the groundwater trends, risk of shallow watertables, and technical feasibility of salinity management in the soil landscape …

Assessment Of Surface Water Runoff And Groundwater Recharge Using Mathematical Models, Khaled Omer Mohamed Haroon

Theses

In arid and semi-arid regions, surface water resources are scarce and, in most cases, groundwater is the only natural resource of freshwater. Pumping of groundwater often exceeds natural recharge. Therefore, groundwater levels are declining and its quality is deteriorating. Sustainable management of groundwater is thus a key issue and requires implementation of appropriate technologies to augment groundwater resources. Artificial recharge augments the natural movement of surface water into the underground formations using some means of construction whereby surface water from streams or lakes is made to infiltrate into the ground.

The UAE is known by its arid conditions and limited …

State Coastal Observations And Monitoring Needs: Results Of A Survey To Assess Coastal Management Needs (Draft Report), Jeff Benoit, Chantal Lefebvre, Dan Hellin, Regan Maund, Jack Thigpen

Urban Harbors Institute Publications

The success of the U.S. Coastal Ocean Observing System will be measured, in part, by how well the needs of the coastal management community are being addressed. The results of this survey indicate that the two most important management issues facing coastal programs are land use and habitat change. It is essential that the planning and implementation of the USCOOS take this fact into account and place a priority on addressing these high priority management needs. This can only be accomplished through the direct long-term involvement of the coastal management community with USCOOS efforts at the national and regional levels. …

Evaluating The Effectiveness Of Simulation-Based Instruction About Water Resources In Las Vegas, Stephanie Fincher

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study compared the effectiveness of simulation-based instruction to traditional teacher-directed instruction about water resource management in Las Vegas. Subjects, undergraduate students recruited from Psychology and Environmental Studies departments, participated in one of two treatments. All participants were given a pretest prior to instruction, a post-test immediately following instruction, and a retention-test 4 weeks after instruction. Evaluation instruments provided overall scores, gauged student learning in topic areas and different question difficulty-levels as well as attitudes toward the environment and water management. The treatments differed only in how students interacted with the system after receiving background information on Las Vegas valley’s …
