Bimonthly benthic samples (April, 1972 to March, 1973) taken at eleven stations provide quantitative reference data on the benthic macrofaunal communities of Lake Worth in Palm Beach County, Florida. Distribution and structure in relation to sediment types and sources of pollution are discussed. One hundred seventy-one taxa were identified. The five top-ranked species were the bivalve Mulinia lateralis; the polychaetes Spiochaetopterus oculatus, Paraprionospio pinnata, and Glycinde solitaria;...
Show moreBimonthly benthic samples (April, 1972 to March, 1973) taken at eleven stations provide quantitative reference data on the benthic macrofaunal communities of Lake Worth in Palm Beach County, Florida. Distribution and structure in relation to sediment types and sources of pollution are discussed. One hundred seventy-one taxa were identified. The five top-ranked species were the bivalve Mulinia lateralis; the polychaetes Spiochaetopterus oculatus, Paraprionospio pinnata, and Glycinde solitaria; and the amphipod Cerapus sp. Stations were grouped as sand, silty-sand, mud, and outfall stations based on similarity of faunal composition and sediment type. The sand and silty-sand stations had the highest diversity (H') and species richness (spp/180) values. The mud and outfall stations had low H' and spp/180 values which were similar to values reported for pollution-stressed areas in other studies. The outfall station was dominated by the pollution-tolerant polychaete Capitella capitata.

Water Resources (WR) agencies have recently shifted to holistic management approaches that combine the use of watersheds and ecoregions as complimentary tools. However, the classification of data is based on land used and land cover detection. In contrast, this research is concerned with inferring WR quality from the landscape using satellite imagery and aerial photography combined with collateral data.

Show moreWater Resources (WR) agencies have recently shifted to holistic management approaches that combine the use of watersheds and ecoregions as complimentary tools. However, the classification of data is based on land used and land cover detection. In contrast, this research is concerned with inferring WR quality from the landscape using satellite imagery and aerial photography combined with collateral data. To conduct the study, three major procedures were devised: (1) construction of a classification system for regional coastal WR, (2) delineation of WR units based on the interpretation of water quality parameters (e.g. land use/cover, soil, vegetation, etc.), and (3) development and implementation of a water quality rating system. The results showed that this technique can be utilized effectively to monitor WR. The distribution of beneficial water quality was correlated with anthopogenic activities and modifications. Temporal events such as sea surface temperature had a short, but detrimental impact on water quality.

Show moreThe South Florida Water Management Model was developed to evaluate proposed alternatives for the south Florida regional hydrologic system. The degree of certainty of the computed system performance measures is required to correctly apply these measures for evaluation and selection of appropriate water resources policies and investments. Initially, a sensitivity matrix is defined which summarizes the model output sensitivity to incremental changes of key parameters. The method of singular value decomposition is applied to the sensitivity matrix to better understand relations between parameters and output variables. Finally, parameter uncertainty is compared to that of total predictive uncertainty of the system performance measures.

Show moreThe C-23, C-24, C-44, North St. Lucie, and Tidal St. Lucie drainage basins in southeastern Florida contribute major pollutant-laden discharges to the St. Lucie Estuary. One of the key goals of several of the Indian River Lagoon Restoration Feasibility Study (IRLRFS) project features is to reduce the timing and delivery of freshwater discharges to estuary receiving waters. The WPA option is the most widely accepted feature. This regional water quality improvement system has been mentioned as either the centerpiece, or major part, of the solution to the St. Lucie Estuary discharge problem. As a result, this research effort seeks to predict WPA water quality impacts to the St. Lucie Estuary. The goal is to utilize numerical water quality modeling techniques to arrive at changes in discharge loading quantities of selected parameters that may result from the operation of the WPA system per its preliminary design.

Show moreA study conducted by the World Health Organization and United Nations Children's Fund, concluded that approximately 768 million people worldwide are not receiving sanitary drinking water suitable for consumption. While there are many water treatment methods, lime softening proves to be one of the more effective approaches as it removes a wide variety of harmful compounds including arsenic, lead, mercury, and cadmium under the correct conditions. The greatest issues with lime softening on a smaller scale include the complexity of the chemistry and need for monitoring. By designing the system for groundwater sources and with a smaller capacity, this thesis hoped to reduce the level of monitoring, chemical expertise, and cost needed for operation. While promising results occurred in the removal of arsenic and total hardness, this project was unable to obtain consistent results and final water samples with pH values between the recommended standard of 6.5 to 8.

The tunicate Styela plicata (Ascidiacea) was investigated for its potential use in bioremediation of bacteria and microalgae blooms from estuarine waters. Salinity tolerances, filtration rate, substrate selection, and effects on digested bacteria and ichthyofaunal communities were examined. If acclimated slowly, Styela can be placed in salinities as low as 24 parts per thousand (ppt) before increased fatalities result. An immediate decrease in salinity from 32 ppt to 20 ppt was not...
Show moreThe tunicate Styela plicata (Ascidiacea) was investigated for its potential use in bioremediation of bacteria and microalgae blooms from estuarine waters. Salinity tolerances, filtration rate, substrate selection, and effects on digested bacteria and ichthyofaunal communities were examined. If acclimated slowly, Styela can be placed in salinities as low as 24 parts per thousand (ppt) before increased fatalities result. An immediate decrease in salinity from 32 ppt to 20 ppt was not detrimental at short term exposure (four days). One average-sized (~40g) Styela, exposed to 105 and 106 bacteria or microalgae mL-1, can filter as much as 4.7 L hr-1 and 3.3 L hr-1, respectively. Individual tunicate filtration rates varied from hour to hour, independent of organism size, indicating that filtration rates for this species would be better reported on a population basis rather than on an individual weight or size basis. Bacterial viability in tunicate feces was assessed by ATP analysis. Bacteria were found to be non-viable after passage through the tunicate digestive tract. Filtration of eggs or larvae of recreationally or commercially important fish is of concern. The smallest eggs (~0.6mm) reported in the Indian River Lagoon belong to Cynoscion nebulosus (spotted seatrout) and Bairdiella chrysoura (silver perch). Over the course of two hours, 72.5% of 0.5 mm glass beads (simulated fish eggs) were initially retained, but many were later expelled by the tunicates. For 1.0 mm beads, 49.4% were initially retained and for 2.0 mm beads, 43.5% were initially retained. Neither the size of the oral siphon nor the size of the overall animal was correlated to bead retention. Substrate selection was investigated using the tunicate Phallusia nigra., Newly hatched larvae preferred settling on wood (53.7%), as compared to polyethylene (30.9%), high-density polyethylene (13.0%), and polyvinyl chloride (2.4%). Overall, results of this study indicate S. plicata is very effective at removing bacteria and microalgae from estuarine waters. However, further testing is warranted regarding the unwanted removal of fish eggs and larvae before utilization of S. plicata for bioremedial purposes.
