Thesis (M. Tech. (Agriculture)) -- Central University of Technology, Free state, 2011 / Quality assessment of agricultural water used for fertigation in the Boland district. The study was undertaken to determine the influence of seasonal changes on the water quality (chemical and microbial analyses) of five different rivers in the Boland. The data was collected in the five most important water sources that are used for irrigation purposes in the district, i.e. Berg river, Eerste river, Klapmuts River, Klippies river and Krom river. The samples were collected from all sites once every three weeks for a period of six months. The sampling was carried out during specific periods in summer (December, 2006 to February, 2007) and winter (June to August, 2007). The results of the study showed that Klapmuts river recorded the highest levels of chloride and iron, especially in summer. However, chloride levels were far below the levels set by the Department of Water Affairs and Forestry. Results obtained from this study show the presence of pathogens in some of the rivers assessed which may have resulted from the leaching of these pathogens from nearby agricultural land, livestock watering or informal settlements in the catchment areas. The bigger rivers recorded low levels of micro-elements and this might have been affected by winter rainfall. In the Berg River, many sources of nitrate pollution seem to be present in the catchment area. The levels of iron in all the rivers assessed were far more than the levels set by the Department of Water Affairs and Forestry in all rivers assessed and these might be due to the pH levels and interaction between the rivers and seasons. Iron and manganese levels should be kept low as this may cause production problems by blocking irrigation drippers. The water samples tested for bacterial and fungal density showed Klapmuts and Eerste rivers were positive for Phytophthora cinnamomi during winter. Phytophthora citricola and Phytophthora cactorum were detected in the Klapmuts and Klippies rivers in summer. The Berg-, Klapmuts-, Krom- and Eerste rivers tested positive for species of the genera Pythium and Fusarium. Similar organisms were detected in the Eerste river mainly during summer on the fourth sampling date, while Krom river only tested positive for Pythium during summer. The total bacterial and algal density differed significantly between the seasons and was highest in winter. This might be due to high rain water influx and efflux and/or moist and aerobic conditions and air temperature. There is an increased need for farmers to sterilize feeding water (chlorination) due to high microbial count.

The study aimed at investigating the factors that affect the efficient management of wastes produced by food outlets in Pretoria, South Africa. This was with a view of providing empirical data and information with respect to the causative factors responsible for the visible environmental pollution by wastes and materials from food outlets. Data was gathered from a representative sample of 332 food outlets on socio-economic, demographic, environmental, sanitary and health related variables that are related to waste management and efficiency in the disposal of solid and liquid wastes. Data entry and analysis was performed using statistical procedures such as frequency tables, Pearson’s chi-square tests of association and binary logistic regression analysis in the statistical package STATA version 10. Odds ratios estimated from logistic regression analysis were used for identifying key factors that affect efficiency in the proper disposal of waste. Results obtained showed that 18 % of the 332 food outlets in the study were generally inefficient in waste disposal. Based on odds ratios estimated from binary logistic regression analysis, wrong perception (a factor of 10.88), failure to provide trash cans to customers (a factor of 3.15), the operation of food outlets by non-owners or managers (a factor of 2.33), and failure to practice source reduction of waste (a factor of 2.25) are the top 4 influential factors that affect the proper management of waste at the 332 food outlets in the study. / Environmental Sciences / M.

Surface water pollution is prevalent in numerous areas of central Roodepoort mainly due to gold mining activities. The surface water quality for the Bosmontspruit, Russell’s Stream and the New Canada Dam was assessed from October 2010 to March 2011. Physical, chemical and biological characteristics of the water were determined for 8 monitoring points and the results obtained were compared with the In-stream water quality guidelines for the Klip River catchment and the South African Water Quality Guidelines. A trend noticed throughout the sampling period was the non-compliance in the levels of total dissolved solids (TDS) and dissolved oxygen. The results indicated that concentrations of iron, aluminium, nickel, manganese and potassium were above the limit across the Bosmontspruit and Russell’s stream. There was also significant evidence of excessive faecal coliform and ammonium pollution in the Bosmontspruit. During the monitoring period it was noted that water from these streams were utilised for crop irrigation, bathing, livestock and human consumption and may pose a health hazard due to poor water quality. / Environmental Sciences / M.Sc.

The study focuses on the role of government in the provision of environmental programmes, events and campaigns. South Africa is a signatory to a number of environmental treaties and protocols hence it is expected to celebrate environmental days annually, such as World Wetland Day, National Water Week, World Environmental Week, Arbor Day and many more. The study considered the community of Masibekela, a remote rural village in Mpumalanga Province under the Nkomazi Local Municipality as its study area. Both qualitative and quantitative methods were applied to gather the necessary data from the four sets of respondents to a questionnaire survey, namely: the Sector Manager of Tonga Environmental Centre, traditional leadership and community members, learners and educators. The study discovered that the provision of environmental programmes, events and campaigns to the study area by the government leaves much to be desired. It lays bare that the community members of Masibekela are neglected environmentally by the government as compared to schools. The study also revealed contrasting features both in the knowledge and celebration of some of the environmental days by both the schools (learners and educators) and the general community members. A high percentage of learners and educators expressed their knowledge and celebration of environmental days since they are frequently visited by government officials to promote environmental programmes, events and campaigns geared towards environmental education and awareness but the same cannot be said about the traditional leaders and community members. It is recommended, among other things, that the Tonga Environmental Centre, as a custodian of provision of environmental programmes, events and campaigns, should be capacitated both in terms of human resources and strategic planning so as to meet its expectations. It is also recommended vi that more funding for bursaries for environmental studies for the youth should be made available and also more capital should be injected into the actual promotion of environmental programmes, events and campaigns. The National Department of Education in collaboration with the Department of Environmental Affairs should consider including Environmental Education in the school curriculum as a compulsory subject in all grades / Geography / M.

In South Africa water is recognized as a crucial element in the battle against poverty, the cornerstone of prosperity, and a limiting factor to growth. The National Water Act 36 of 1998 recognizes that basic human and environmental needs should be met and that the use of water in all aspects must be sustainable. The Crocodile River (East) is situated in the north east of the Republic of South Africa and it is recognized as a stressed catchment in South Africa. The main impacts are domestic, industrial, agricultural, mining and afforestation activities. These activities pollute the river by discharging effluent as well as seepage from areas that support mining and intensive agriculture in to the river. The river catchment has been a center of research studies for many scientists either focusing on water quality or biological indicators separately. The aim of study was to determine the present ecological condition and the health of the Crocodile River. The objectives were to determine water quality status, identify possible sources of pollution and assess the spatial and temporal trends in ecological state. Fourteen monitoring sites were selected from the Crocodile River and its tributaries. The macro-invertebrates data were collected using the SASS 5 protocol and fish were collected using an electroshocker- catch and release method during high and low flow conditions of the year 2013. Water quality data was obtained by sampling using a polyethylene bottle from different sites within the Crocodile River and its tributaries from September 2012 until August 2013. The samples were analyzed by Mpumamanzi laboratory in Nelspruit and Waterlab in Pretoria. Additional water quality data was obtained from the Department of Water Affairs. Multivariate statistical methods were used to analyze all the data obtained. The multivariate statistical methods indicated that fish and macro-invertebrates species abundance, richness and evenness increase with the river flow distance downstream. Water temperature was one of the leading environmental variables for the structuring of fish and macro-invertebrates assemblage in the Crocodile River and its tributaries. A group formation of site during high and low flow condition by the Bray Curtis similarity and NMDS ordination indicated that many sites share similar macro-invertebrates or fish species. The one way ANOVA analysis indicated that there was no significance difference between macro-invertebrates richness and abundance during both flow conditions but there was a significance difference in fish richness and abundance between the two flow conditions. The PCA indicated that sodium has the highest physico-chemical impact amongst the physico-chemical parameters in the bi-plot followed by ammonium and nitrate. A correlation of physico-chemical parameters such as chlorine, total dissolved solid, electrical conductivity, sulphate and pH was observed. The levels of total dissolved solids and electrical conductivity were found to increase longitudinally as the river flows downstream. The dominance of single species within the macro-invertebrates and fish communities was an indication of imbalance of the communities within the sites. The presence of the macro-invertebrate family Beatidae and the fish species Chiloglanis pretoriae at sites CR3 and CR4 indicates a good water quality in the upper reaches during low flow condition as these species are sensitive to changes in water quality, while the presence of the macro-invertebrate family Pleidea and fish species Barbus viviparus at sites CR10 and KR1 during low flow condition indicated possible water pollution as these species tolerate changes in water quality and this was linked to the discharge of effluent from industrial, abandoned mines and run-offs from agricultural activities in the downstream reaches of the river. The low flow condition was dominated by sensitive species especially in the upper reaches than during high flow condition. The macro-invertebrates assessment index indicated that during low flow condition the Crocodile River was mostly at ecological class B (largely natural with few modification) above the Kwena dam, but from downstream of the dam the ecological category was in C class (moderately modified), while its tributaries are in ecological category B (largely natural with few modification). The fish response assessment index indicated that the ecological category for fish was mostly at C class (moderately modified) in the Crocodile River. The changes in macro-invertebrates communities and fish in the Crocodile River were believed to be associated with change of water quality and habitat modification due to flow modification. Agricultural activities in the upper reaches and a combination of industrial and mining activities in the middle and lower reaches of the Crocodile River were believed to be the sources of pollution that results in the change of water quality, fish and macro-invertebrates assemblage in the Crocodile River. Investing in the health of the Crocodile River is important for many Mbombela citizens and river dwellers as they rely on the functioning of the river for survival. / Environmental Sciences / M. Sc.

Chemical (gaseous) emissions from wastewater treatment plants (WWTP) are perceived as odour and can generate undesirable health reactions. These could affect the quality of life to those regularly albeit intermittently exposed, although regular exposure may result in tolerance and loss of recognition of the odour. Consequently, research is necessary to establish the role of Environmental Impact Assessment (EIA) in ensuring that facilities such as WWTP do not pose a threat to local communities, particularly in relation to housing developments for poor communities. The aim of this study was to investigate if the EIA regulations were effectively implemented before building of the Residential Development Proiect (RDP) houses at KwaMathukuza, in Newcastle South Africa. Furthermore, the study intended to determine the impact the (WWTP) has on the health of people who reside close to the site and to establish if the families staying close to the WWTP have any common ailments such as handicapped babies, early deaths within families. Findings would also indicate if RDP houses should be built in close proximity to such sites. Data was collected through a survey of 85 residents living within five kilometers and ten residing beyond five kilometers from the WWTP. The participants were selected randomly. Municipality employees who worked with the WWTP were also sampled together with healthcare givers. Data included information about health of the community, their perception of the gases released from the WWTP as well as EIA meetings and processes related to the construction of the RDP houses. The outcome of this study revealed that EIA regulations were not adequately implemented and that this residential site was unsuitable for the construction of RDP houses. It emerged that the residence regularly experience unpleasant odours released from the WWTP. These could be associated with ill-health of the residents as well as v degradation the environment in general. The study also found that the effect of the WWTP affects even those communities who reside beyond five kilometers from the WWTP. The researcher argues for more stringent mechanisms to ensure that EIA regulations are properly implemented to prevent adverse effects on the communities. / Environmental Sciences / M. Sc.

Steroid hormones belong to a group of compounds known as endocrine disruptors. They are hydrophobic compounds and are categorized as natural and synthetic estrogens. Some common household products have been implicated as estrogen mimics. Exposure effects of these compounds are felt by human and wildlife, such reproductive alterations in fish and frogs. They mainly introduced into the environment through veterinary medicines administration to animals and the discharges from wastewater treatment plants (WWTPs). In this study, a new alternative analytical procedure that is simple, rapid and fast for the determination and quantification of five steroidal hormones: estriol (E3), beta estradiol (β-E2), alpha estradiol (α-E2), testosterone (T), progesterone (P) and bisphenol A (BPA) using the High pressure liquid chromatography coupled to a charged aerosol detector (HPLC-CAD). These compounds were studied because of their strong endocrine-disrupting effects in the environment. Under optimum conditions, a linear graph was obtained with correlation coefficient (R2) ranging from 0.9952 - 0.9996. The proposed method was applied to the analysis of water samples from a wastewater plant and the results obtained were satisfactory. The limits of detection (LOD) for the target analytes in wastewater influent was between 0.0002 – 0.0004 μg/L and the limit of quantification (LOQ) was 0.001 μg/L respectively for each of the analytes. Enrichment factors of 148- 258, and extraction efficiency 84- 102% were obtained for the target analytes; relative standard deviations (% RSD) for m = 6 were between 2.8 and 7.6%. The concentration of the EDCs in environment sample was between 0.2 - 2.3 μg/L. / Chemistry / M. Sc. (Chemistry)

Submitted in fulfillment of the requirements of the degree of Master of Health Sciences in Environmental Health, Durban University of Technology, Durban, South Africa, 2016. / In South Africa, under-five childhood morbidity and mortality rates have increased due to diarrhoea with acute diarrhoea posing a major public health threat especially, in informal settlements. Therefore this study sought to, a) investigate community knowledge, attitudes, behaviour and practices (KABP) regarding domestic waste and childhood diarrhoeal management, b) to enumerate and identify diarrhoeagenic E.coli species from soil samples extracted from open waste dump sites and c) to investigate any association(s) with diarrhoeagenic E.coli and potential risk of contracting diarrhoea. This two-phased cross-sectional study in six informal settlements in the greater Durban area constituted, respectively, of the administering of questionnaires to 360 primary caregivers and; sampling the prevalence of diarrhoeagenic E.coli (DEC) in waste dumps using quantitative polymerase chain reaction methodologies. Relationships between socio-demographic and educational status to determine potential household risk factors towards under-five diarrhoea prevalence were assessed. The KABP results identified domestic waste and greywater disposal, mother and child method of sanitation, personal and domestic hygiene practices and mechanical vectors as significant contributory risk factors. Of concern is that more than 80% of under-five children played in or near faecally-contaminated waste dump sites. The recovery of four DEC pathotypes including enterohaemorrhagic E.coli, enteropathogenic E.coli, enterotoxigenic E.coli and enteroaggregative E.coli suggest that its persistence in waste-dump soil has the ability to cause under-five diarrhoea in both sporadic and endemic settings. This commonly transmitted hand-to-mouth illness will necessitate and place huge demands on the primary catalysts of change i.e. local governmental role players and caregivers. These change agents have to ensure highly consistent levels of domestic and personal hygiene and implement feasible reduction strategies to waste-dump exposure of diarrhoeal-causing pathogens, particularly among under-five children living in Durban’s informal settlements. / M
