In recent years the problem of water pollution has been recognized as a meta-problem of unexpected magnitude and complexity. Early attempts to control pollution were stifled by the property-oriented common law of riparian rights and by the lack of Authorities possessing adequate jurisdiction and funds. The object of this paper is to delineate the proper legislative and administrative field of water pollution control, with particular reference to British Columbia's pollution control legislation. As a background, the common law relating to water pollution is sketched and its adequacy evaluated. Early British Columbia Pollution control legislation is outlined in an attempt to determine the roots of the present comprehensive legislation. The Pollution Control Act 1956 is examined, with particular attention to the administrative tribunal created thereunder. Board procedures are seen to be informal and dependent upon direct communication and negotiation with individuals concerned. An attempt is made to determine the criteria upon which the Board acts in setting effluent standards in waste disposal permits granted by it. These standards are found to be vitually completely in the Board's discretion, but necessary (with some limitations) for flexible policy administration. The Board has several means of enforcement at its command including prosecution under the Act, or under the Criminal Code and civil proceedings at the suit of the Attorney-General. To determine whether civil actions for pollution lie apart from the Act, the question of whether riparian rights have been abrogated in British Columbia by water appropriation legislation is considered. The evidence indicates that actions by riparian owners will continue to lie. The fact that parties hold either water licences or pollution control Board permits makes no difference if pollution in fact exists. The Board is an administrative tribunal; but it may at certain stages of its permit issuing procedure be required to act judicially. At those stages, the Board's decision is open to review by the courts. Under the present legislation a person who objects to the grant of a permit is not entitled to an oral hearing, though he is entitled to file written representations in support of his objection. There appears to be no conflict among the numerous pollution control provisions contained in various provincial statutes. The Pollution Control Act is clearly the governing legislation. Federal Legislation relating to pollution is validly enacted under Federal Fisheries and Navigation powers; and in a case of direct conflict will override the provincial legislation. From the preceding examination of the Act, it is concluded that while certain minor changes suggested might to some degree remedy the present legislation, what is required is a policy making, expert tribunal. An important recommendation is that to secure individual rights, a hearing should be granted every person who files an objection to a permit application. New legislation recently introduced in the British Columbia Legislature provides for appointment of a Director, who will undertake day-to-day administration of the Act. However, the Board will continue to be subject to direction by the Executive Council, and the right to a full oral hearing upon an objection will remain discretionary. / Law, Peter A.

The purpose of this thesis is to evaluate the existing and alternative mechanisms for water pollution control in the Paraiba do Sul River Basin, in Brazil. It focuses on mechanisms-for controlling point-sources of pollution. The physical features, economy, and institutions of the Paraiba River Basin are described and the water quality problems and technical opportunities for their solution are examined. The analysis is based upon reports done by the state pollution control agency (CETESB) and field investigations which involved interviews with CETESB's personnel at the central office, in Sao Paulo, and the regional office, in Taubate. The analysis of the water quality problems and technical opportunities for their solution indicates that treatment of municipal discharges is of paramount importance for the realization of the water quality standards in the Paraiba River and that this can be done, at minimum cost, by adopting facultative lagoons for sewage treatment. It also indicates that such a solution would cause dissolved oxygen levels to rise well above the standard in most sections of the river. This means that additional assimilative capacity for biochemical oxygen demand (BOD) would be created which could possibly be allocated to other dischargers. Such a solution to the municipal sewage problem would, however, impose a heavy burden upon municipalities and is not likely to come about unless municipalities are helped financially. The ability of the mechanism to provide municipalities with some financial assistance and to allocate the assimilative capacity of the river both efficiently and equitably were the two criteria applied in assessing the existing system for pollution control in the Paraiba River. Basin, the effluent charge system, and the transferable discharge permits (TDP) system. This assessment indicates that only a modified TDP system is likely to bring about the realization of the water quality standards established for the Paraiba River. An illustrative example of the application of the TDP system to a section of the Paraiba River is developed which suggests that such a system would be able to adapt to changes in wasteloads discharged to the river and would have the potential for reducing the financial burden upon municipalities if allocations of permits to municipalities are greater than discharge requirements with facultative lagoons. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

When mining activities in some parts of the Witwatersrand were discontinued in 2000, the defunct workings started to flood. In September 2002 the mine water started to decant from the West Rand Mine Basin (WRB) next to the Tweelopie East Stream. Treated water is currently used in the mine's metallurgical plants and 15Ml per day of treated water is disposed firstly into the Cooke Attenuation Dam and then discharged into the Wonderfonteinspruit. The aim of this study was to find and provide remediation measures as a result of acid mine drainage and other impacting factors on the water quality and volume in the Wonderfonteinspruit. Conductivity and total dissolved solids (TDS) were highest at the point where the tailings dam leached into the Wonderfonteinspruit. Sulphate was very high as was expected due to acid mine drainage. The best way to treat the high sulphate levels is with sulphate-reducing bacteria. To avoid the fatal flaw of many other constructed wetlands, a continuous carbon source is provided to the bacteria in the form of activated sewage from the Flip Human sewage treatment plant. Iron and other heavy metals are being precipitated through oxidation reactions to form oxides and hydroxides from the aerobic cell in the wetland. The wetlands are also known for their ability to reduce nitrate and microbial values with great success. In the remediation, four elements that currently do not comply with the SABS criteria for class 0 water, were chosen for improvement: conductivity, dissolved solids, sulphate and iron. Conductivity falls within class 1 and has a maximum of 178 mS/m @25ºC that should be reduced to under 70 mS/m. Total dissolved solids have a value of 1585 mg/l, which is much higher than the prescribed 450 ml/l, making it class 2 water. The last two problematic elements are both considered as class 2 water: sulphate peaks at 592 mg/l where the preferred value is 200 mg/l, and iron should be 0.01 mg/l, not the staggering 0.3mg/l. iv Alternative mitigation methods were identified and analysed for the impacts of the five major contaminators and ultimately the solution comes down to constructed wetlands. This is not a straightforward solution, however, and a specific design to accommodate all the different pollutants and water quality ranges was proposed. The other mitigation methods include a cut-off trench and pump-back system for the tailings dam, as well as the implementation of a monitoring programme. The sewage works should be optimised and better managed. Both the settlement and agricultural sector need to be educated on their representative impacts on the environment and government assistance should be available. / ENVIRONMENTAL SCIENCES / MSC (ENVIRON MANAGEMENT)
