Esso’s Long Island Point facility has been operating for more than 40 years beside Western Port in Victoria, and has discharged treated wastewater and storm water to the bay for most of these years. The 2001 State Environment Protection Policy Schedule F8 for Waters of Western Port is part of Victoria’s Environment Protection Authority’s (EPA) legal framework for licensing discharges to the waters of Victoria, and requires that discharges ‘cause no detrimental change in the environmental quality of the receiving waters, as determined by an environmental monitoring program’. As part of Esso’s ongoing commitment to continuous improvement, a major upgrade to the water treatment facility was completed to further improve the quality of waters discharged to Western Port. In conjunction with this upgrade, Esso is undertaking a study on the effects of the discharge on the environmental quality of Western Port. This peer-reviewed paper presents an example of the practical application of managing discharges to ensure that the stated environmental values of a receiving environment are protected. The environmental study focuses on four key aspects of marine-environment quality relevant to key Western Port ecosystem values in the vicinity of the facility’s effluent discharge, which are: ambient water quality; seagrass biomass; jetty pile epibiota; and, ecological risk through toxicity testing. The study demonstrates the implications of basing regulatory requirements on the quality of the site-specific environmental characteristics, rather than merely effluent quality and generalised water quality objectives. Furthermore, it validates the need for sound science to underpin regulatory limits and industry practices when operating in sensitive environments.

AbstractVictorian Bluestone is proposed as a Global Heritage Stone Province from Australia. Numerous heritage stones occur within this province and of these Malmsbury Bluestone is suggested as a Global Heritage Stone Resource. Bluestone, an iconic basalt dimension stone from Victoria, is used domestically and internationally with a recognized heritage value. Sources are located in urban and country areas of Victoria some of which are still utilized for dimension stone. In many instances bluestone has superior technical characteristics, including durability, that surpass high-quality commercial sandstones, despite an architectural preference for lighter-coloured stones. These characteristics are matched by the diversity of significant uses for domestic, commercial and infrastructure purposes especially in Victoria. Notable examples include the Spotswood Pumping Station, Malmsbury Viaduct, the Graving Dock (Williamstown), Malmsbury Reservoir, St Patrick's Cathedral (Melbourne), Kyneton Railway Station and Ararat Gaol. If the bluestone used in pavements and drains is also considered, Victorian Bluestone could be described as Australia's most prominent infrastructure heritage stone. Bluestone use in Melbourne dates from the 1840s, in the other states of Australia and in New Zealand from 1873, with international interest from Asia between 1860 and 1880. The stone continues to be utilized widely around Australia and is also exported.

Four forest reserves within 50 km of Kampala in Uganda act as a critical buffer to the Lake Victoria watershed and habitat for local populations. Over a 9-month period we capture a pioneering water quality data set that illustrates ecosystem health through the implementation of a water quality index (WQI). The WQI was calculated using field and laboratory data that reflect measured physical and chemical parameters (pH, dissolved oxygen, biological oxygen on demand, nitrates, phosphates, fecal coliform, and temperature turbidity). Overall, the WQI for the four forest reserves reflect poor to medium water quality. Results compared with US Environmental Protection Agency and World Health Organization drinking water standards indicate varying levels of contamination at most sites and all designated drinking water sources, with signatures of elevated nitrates, phosphates, and/or fecal coliforms. As critical health problems are known to arise with elevated exposure to contaminants in drinking water, this data set can be used to communicate necessary improvements within the watershed.

Federal and state laws mandated secondary sewage treatment for all municipal dischargers in the state of Washington regardless of need. Evidence supported the suitability of lesser amounts of treatment and the use of industrial source controls as protective of water quality, but could not be considered. The full implementation to secondary treatment is now complete. In the 1990's, the media, environmental activists and various local, state and federal politicians from Washington State became upset with Victoria, British Columbia when they realized that most of the sewage from the greater Victoria area was only screened prior to discharge to the Strait of Juan de Fuca. The perception was tainted by a lack of understanding of the benefits and power of rapid dilution, and also the mistaken impression that the excessive treatment requirements in Washington were actually needed for water quality reasons. A British Columbia/Washington State Marine Science Panel was established by the political leaders of the province and state to examine issues of the shared marine waters. The Panel concluded Victoria's discharges were not a problem. The media in Washington State did not report this, and the director of the state's environmental agency expressed disappointment rather than relief with the finding.

Water quality prediction has great significance for water environment protection. A water quality prediction method based on the Improved Grey Relational Analysis (IGRA) algorithm and a Long-Short Term Memory (LSTM) neural network is proposed in this paper. Firstly, considering the multivariate correlation of water quality information, IGRA, in terms of similarity and proximity, is proposed to make feature selection for water quality information. Secondly, considering the time sequence of water quality information, the water quality prediction model based on LSTM, whose inputs are the features obtained by IGRA, is established. Finally, the proposed method is applied in two actual water quality datasets: Tai Lake and Victoria Bay. Experimental results demonstrate that the proposed method can take full advantage of the multivariate correlations and time sequence of water quality information to achieve better performance on water quality prediction compared with the single feature or non-sequential prediction methods.

Waterwatch is a national community-based monitoring network that aims to involve community groups and individuals in the protection and management of waterways. Waterwatch Victoria has the dual objectives of catchment education and water quality monitoring. The educational outcomes are evident, with the Waterwatch programme facilitating over 9,000 students to monitor more than 2,000 sites in waterways in 2000. This paper aims to assess the scientific value of community-collected data, through examining differences between Waterwatch data and professionally collected data. The study looked at all aspects of volunteer data collection, including data confidence protocols, equipment, and data analysis. All professional data was collated by the Victorian Water Quality Monitoring Network (VWQMN). The parameters examined in this study were turbidity, electrical conductivity (EC), pH and total phosphorus. The level of agreement between community-collected data and professional data varied temporally and spatially. Waterwatch data for EC and pH appeared to be very similar to professionally collected data. Equipment used by Waterwatch volunteers for turbidity and total phosphorus appeared to be limited in accuracy to moderate ranges. Overall the VWQMN professionally collected data showed less variance, suggesting greater variability, potentially due to inaccuracies, in volunteer collected data.

Between February 1975 and March 1977, periphyton from artificial substrata (glass microscope slides) and water samples for physicochemical analysis were obtained from eight sites on the lowland section of the La Trobe River, which flows through agricultural, urban and industrial areas. Total organic matter on the slides, estimated as weight loss on ignition, was usually highest in summer or autumn when river flows were low. However, chlorophyll a densities generally peaked in late winter and spring when nitrate concentrations were high, except at a site upstream of major urban and industrial areas, where a summer-autumn increase occurred. Thermal discharges from major power stations had no obvious effect on chlorophyll abundance, but did appear to substantially influence diatom assemblage composition from late summer to early winter, when river temperatures were highest. Downstream of the Morwell River confluence, diatom assemblages were influenced by a sharp increase in dissolved solids concentration and probably also by the grazing activities of snails (Ferrissia petterdi and Physastra gibbosa). The diatom flora at the most downstream site showed some evidence of recovery from thermal effects.

This thesis investigates the distribution and significance of stream turbidity in Victoria; specifically exploring the factors that may have influenced the pattern of regional variation in turbidity, and factors that give it significance in the regional, social, cultural and environmental context. The limits to water availability are set, not only by the quantity of water in storages or streams but, more fundamentally, by acceptable levels of water quality and catchment health. To make effective judgements of water availability managers of water resources need to know the significance of measured natural resource condition in the regional context. Stream turbidity can be considered by the agricultural community as a sign of soil erosion and a loss of agricultural potential, while from the ecological perspective it can be considered a sign of deteriorating river health. Fundamentally, levels of turbidity are closely bound with land use practice and, in the Australian context, turbidity can be considered a measure of the consequences of land management practices on soil erosion and run-off. Measured levels of turbidity in Victoria should be interpreted within the context of a unique history and geography. The spread of European colonisation and the introduction of massive land use change to the Victorian landscape have meant that over most of Victoria current levels of turbidity reflect the effects of over a hundred and fifty years of large scale intervention with its controlling factors. In Victoria current levels of turbidity are interpreted in a cultural context far different from that of early colonists or even of a few decades ago. The concept of Ecologically Sustainable Development which has dominated natural resource management in recent times brings new responsibilities to resource managers. Ecologically sustainable management means that resources must be considered in a more inclusive spatial and temporal context. In the early stage of Victoria's history sustainable management of water meant having enough water left from winter rains to supplement summer supply. However, in recent years, it has begun to have more complex associations; sustainable water use is now, almost universally considered to include maintenance of the environmental health of waterways, and by implication, the environmental health of the whole catchment. In this context, stream turbidity can be considered a useful indicator of catchment health, in particular, because levels of turbidity bear a direct physical relationship to catchment processes. New tools are needed to explore the relationship between land use and water quality at the regional scale. The results of this current research include a regional statistical model of stream turbidity, which is conceptually designed to offer useful predictions of stream turbidity and underpin sustainable resource management. The statistical model was used as input to the development of a unique map display using Geographic Information Systems (GIS). The GIS is used to display the distribution of model predictions over a large region of south-eastern Australia. The practical advantage of this modelling approach is that it provides managers with the ability to identify locations in Victoria where measured water quality differs significantly from modelled water quality and flag them for further investigation. The major project outputs are a map of Victorian Water Quality Monitoring Network (VWQMN) catchments showing catchments in Victoria where measured turbidity differs from model predictions and a raster representation of the state of Victoria in which cell values indicate predicted stream turbidity. Important to this project was the novel use of GIS technology to process large national and regional scale digital data sets using tools developed for catchment scale hydrological models.

The concentrations of various forms of nitrogen and phosphorus in the main stream and selected tributaries of Pirron Yallock Creek, southwestern Victoria were examined over a two-year period. Exceedingly high levels of both nutrients were found within a particular tributary, while generally high nutrient levels were observed throughout the catchment. The speciation results indicated that dairy effluent was the primary source of nutrients to Pirron Yallock Creek. A palaeolimnological study was undertaken to determine the impact of European settlement upon waterway nutrient concentrations within the region. The palaeolimnological study focused primarily on the diatom flora preserved within the sediments of nearby Lakes Corangamite and Bullen Merri. Lack of preservation of diatoms within the sediments of Lake Corangamite resulted in no water quality inferences for this lake. The preserved diatoms within Lake Bullen Merri suggested an increase in trophic status of this lake during the last 500 years. While a change in the diatom flora of Lake Bullen Merri was evident, it was not possible to differentiate the impact of European settlement upon nutrient status of this waterway from long-term trophic status change. In light of the particularly high nutrient concentrations observed in Pirron Yallock Creek, improved nutrient management strategies are proposed for the catchment. These strategies, which consider current nutrient management activities, are predominantly focussed on the dairy industry, which occupies the majority of the catchment.

The intensive nature of land uses in the Strzelecki Ranges poses significant threats to landscape values and water quality. A comprehensive catchment strategy was developed based on sustainability science concepts incorporating the careful management of landscape values, proper land management approaches, and government policy and legislative change to ensure that agriculture, forestry and other land uses become sustainable in this sensitive environment. The readily measurable water quality indicators of turbidity, flow, electrical conductivity, and water temperature were used to determine the impacts of the major land uses in the Strzeleckis. From a water quality perspective, there was a trend of decreasing water quality with increasing intensity in land management. However, from a total sediment load perspective, the forest area contributed the highest total sediment load due to higher volumes of steam flow suggesting that natural processes in the Strzeleckis may remain the principal mechanisms for sediment movement within the catchment. An incidental but significant finding was extensive bioturbation along the riparian zone of the plantation area, the extent of which was not observed in the other catchments. This finding suggested that bioturbation may have been the most significant contributor to poorer water quality flowing from in the plantation catchment. The project developed insights into the major environmental processes active in the upper catchment of the Morwell River. Understanding of the contributions to total sediment loads from natural erosional processes and bioturbation, findings related to the impacts on water quality from agricultural practices, and encountering negligible impacts from conservative timber harvesting practices demonstrate that catchment management approaches need to be tailored to achieve sustainability in land uses across the landscape. Key recommendations include the re-establishment and protection of riparian zones in agricultural catchments, the careful assessment and setting of stream buffer zone widths for timber harvesting operations, and the need for further work to map the extent of natural processes such as bioturbation and stream bank erosion. To mitigate these issues, government policy and legislation will need to focus on the preservation and enhancement of the Crown land riparian zones. Recommended changes to current administrative land management arrangements for these sensitive areas include a move from licensing riparian zones for agricultural practices such as grazing to conservation.

Water resource management is becoming more complex and relies heavily on computer software processing to help data queries for common and rare patterns for analyzing critical water events. For example, it is vital for decision makers to know if certain types of water quality problems are isolated (e.g. rare) or ubiquitous (e.g. common) and whether the conditions are changing spatially or temporally for a proper management plan. This thesis aims to automatically detect spatiotemporal common and rare patterns by significantly addressing the uncertainty and heterogeneity in water quality data, in order to enhance the accuracy and efficiency of common and rare pattern mining models underpinning many of the water resource management strategies and planning decisions. Therefore, we propose two novel semantics-oriented mining methods: the Correcting Imprecise Readings and Compressing Excrescent Points (CIRCE) method and the Exceptional Object Analysis for Finding Rare Environmental Events (EOAFREE) method. The CIRCE method resolves uncertainty problems in retrieving common patterns based on spatiotemporal semantic points, such as inflexions. The EOAFREE method tackles the heterogeneity problem by summarizing raw water data into a water quality index, that is, water semantics, in discovering rare patterns. We demonstrate the efficiency and effectiveness of the two methods by using simulation and real world datasets, and then implement them in a Semantics-Oriented Mining Application for Detecting Water Quality Events (SOMAwater) prototype system, which is used to query spatiotemporal common and rare patterns for a real world water quality dataset of 93 sites in 10 river basins in Victoria, Australia from 1975 to 2010.

The development and use of any specific model depend on the availability of data and the hydrological settings of a country. Because of data limitations (especially water quality and land management data), the water quality models developed for Australian catchments are lumped/semi-distributed conceptual models. Even within these modelling frameworks, water quality component is empirical or generation rates-based. In this context, developing an effective water quality management plan in the data-poor conditions of Australia still remains as a major challenge for water catchment managers, despite huge investment on river health improvement programs. Physics-based distributed water quality models such as SWAT are most suitable for agricultural non-point source pollution studies. However, because of high data requirement and processing, the applications of these models are limited in many datapoor catchments. In this study, relevant input data sources and analysis techniques were addressed especially for sparsely available water quality data to assemble, and to rigorously calibrate and validate the SWAT based Middle Yarra Water Quality Model (MYWQM) for the case study area - Middle Yarra Catchment (MYC) of Victoria, Australia. The regression based model LOADEST was used for estimating sediment, and nutrient observed loads from monthly water quality grab sample data. The MYWQM was then used to develop a water quality management plan for agricultural non-point source pollution in the MYC. In general, the MYWQM was found capable of predicting streamflow, sediment and nutrient loads in the MYC. The model was also found effective for simulating individual and integrated effects of several Best Management Practices (BMPs) in the MYC. Moreover, the model showed that the in-stream processes if not considered can result in incorrect estimates when simulating BMPs in the model. Overall, the performance of the MYWQM on evaluating the BMPs in the MYC demonstrated that data-intensive physics-based models can be applied in the data-poor conditions of Australia.

Accurate information on the state of water resources in the Lake Victoria watershed is crucial for planning and sustainable development in the East African region. This region largely depends on its natural resource-base for economic development, and therefore comprehensive information on its resources dynamics is key in implementing poverty alleviation strategies, improving human condition and preserving the biological systems upon which the region‘s population depends. This chapter focuses on key issues, which have emerged as a result of population growth and development in the region. The research on which this chapter is based aims to address the concerns on land use and settlement trends in the study sites, vulnerability of the communities to water stress and sustainability of the livelihood systems in the watersheds of Nzoia River Basin (Kenya), Nakivubo Wetland (Uganda) and Simiyu River Basin (Tanzania). These communities engage in unique land use practices that have intensified environmental degradation in recent times. The research adopts a multi-disciplinary approach in bringing to the fore the various processes affecting watershed resources use and management in the selected wetlands of the Lake Victoria Drainage Basin (LVDB). The data presented covers trends in vegetation cover loss, pesticide pollution and general water quality parameters. Geographic information systems (GIS) and remote sensing techniques were employed to unveil land use patterns that have resulted in the degradation of the watershed. Wetland degradation levels have been characterized using secondary data generated by analytical techniques. New emerging challenges of environmental degradation caused by industrial, domestic and agricultural activities are presented and discussed. The potential of the new science of hydroinformatics in integrated watershed management through mathematical modeling, geographic information systems analysis and water supply management is highlighted.

While HEW and USDA pondered these appellate court decisions, we turned our attention to several more local DDT problems. From a New York Times article (May 3, 1970), we learned that the Olin Chemical Corporation was manufacturing about 20% of the nation’s DDT in buildings owned by the federal government and leased to Olin on the site of the U.S. Army’s Redstone Arsenal near Huntsville, Alabama. A DDT-contaminated effluent from this plant was leaking into the Wheeler National Wildlife Refuge at concentrations known to inhibit reproduction of birds and fish. The refuge also served as a drinking water supply for the city of Decatur, implying a human health hazard as well. Downriver fisherman were also eating their catch, thus concentrating DDT to higher levels as well. In October 1969, the federal Water Quality Administration had recommended a stricter pollution control standard for the Olin plant. Olin said it could not meet that standard, and the Army then overruled the Water Quality Administration’s recommendation. So on June 5, 1970, EDF, along with the National Audubon Society and the National Wildlife Federation, sued in Federal District Court against Olin, the Department of the Army, and the Corps of Engineers seeking to stop the DDT-contaminated discharge. The complaint was written by EDF’s new attorney, Edward Lee Rogers. I supplied the scientific support, which was easy, since it was similar, although steadily expanding, to the Wisconsin hearings and the USDA and HEW cases. Only three days later Olin threw in the towel! On June 8 Olin decided to close its DDT plant and no longer make DDT. DDT apparently was not worth defending. They said they had reached that decision shortly before our case was filed. True or not, it was a quick and easy victory. We needed it. We had won by winning. Even as the legal briefs went back and forth between EDF, USDA, HEW, and the appeals court, another DDT battle was brewing in California. For years scientists had been puzzled by the extremely high levels of DDT contamination along the coast of Southern California compared with other marine environments.
