December Newsletter - Looking Forward to 2017
December Newsletter - Looking Forward to 2017 2016 has been a very busy and eventful year for everyone. We finished the year on a high note, when our Chairman Dr. Colinda Linde and Vice Chairman Dr. Frans Korb, were invited to the South African Medical Association (SAMA) Gauteng offices in Johannesburg on the 10th November where we were awarded the Member of Society Award by Dr. Grootboom, Chairperson of the Executive Committee of SAMA. This award recognises 'an organization in society that has made an extraordinary, selfless contribution to the health and welfare of society in general.’ Click here for more info. This reward reflects the determination and commitment SADAG has to increasing the understanding and acceptance of mental health and mental illness in South Africa. We have worked consistently this year through various projects. Some of these activities include: our continued partnership with Akeso and establishing a new helpline dedicated to patients leaving inpatient care, the collaboration with Netcare to train more support group leaders in Alexandra, Eersterust, Benoni, Krugersdorp, Hartbeespoort, Phokeng, Rustenburg, Zeerust, Parys, Kroonstad, Odendaalsrus, Sasolburg, the launch of the university helplines for both UCT and UP, and the bi-monthly Mental Health Matters Journal, which focuses on providing useful information to GPs. We have also remained adamant on our stance with regards to the Life Esidimeni Crisis, and have worked closely with numerous organisations and interested parties in making sure that this issue is not swept under the rug. We continue to fight for patients' rights, and we are waiting for the report from the Health Ombudsman's investigation. -

Draft Air Quality Management Plan
BOJANALA PLATINUM DISTRICT MUNICIPALITY DRAFT AIR QUALITY MANAGEMENT PLAN May 2011 DRAFT 1 REPORT AUTHORS Nokulunga Ngcukana - Gondwana Environmental Solutions (Pty) Ltd Nicola Walton - Gondwana Environmental Solutions (Pty) Ltd Loren Webster - Gondwana Environmental Solutions (Pty) Ltd Roelof Burger - Climatology Research Group, Wits University Prof. Stuart Piketh - Climatology Research Group, Wits University Hazel Bomba - Gondwana Environmental Solutions (Pty) Ltd 2 EXECUTIVE SUMMARY INTRODUCTION The National Environmental Management: Air Quality Act 39 of 2004 (AQA) requires Municipalities to introduce Air Quality Management Plans (AQMP) that set out what will be done to achieve the prescribed air quality standards. Municipalities are required to include an AQMP as part of its Integrated Development Plan. The AQA makes provision for the setting of ambient air quality standards and emission limits on National level, which provides a means evaluating air quality. Due to the implementation of the AQA, the philosophy of managing air quality in South Africa moved from a point source base approach to a more holistic approach based on the effects on the receiving environment (human, plant, animal and structure). The philosophy is based on pro-active planning (air quality management plans for all municipal areas), licensing of certain industrial processes (listed processes), and identifying priority areas where air quality does not meet the air quality standards for certain air pollutants (Engelbrecht, 2009). Air quality management is primarily the minimisation, management and prevention of air pollution, which aims to improve areas with poor air quality and maintain good air quality throughout. In light of this legal requirement, the Bojanala Platinum district municipality (BPDM) developed this AQMP. -
Social Paradigm Shift Required to Counter the Eutrophication of the Hartbeespoort Dam in South Africa
Water and Society V 159 SOCIAL PARADIGM SHIFT REQUIRED TO COUNTER THE EUTROPHICATION OF THE HARTBEESPOORT DAM IN SOUTH AFRICA INGRID DENNIS & STEFANUS RAINIER DENNIS Centre for Water Sciences and Management, North-West University, South Africa ABSTRACT Sewage discharges are poisoning major rivers and dams in South Africa, including the Hartbeespoort Dam. High nutrient concentrations promote algae growth, leading to eutrophication. The dam has been in a hypertrophic state since the early 1970s. Mismanagement of waste water treatment works (WWTWs) within the catchment area are largely to blame, with over 280 tons of phosphate and nitrate deposits. Point source pollution in the form of malfunctioning WWTWs and diffuse sources from informal settlements present along streams and rivers within the catchment area, are responsible for the high nutrient levels. Many of these settlements use water directly from the river/stream. The first step to address the problem of eutrophication is by reducing the nutrient source. A conservative mass transport model was developed to predict phosphate levels and was used to assess the impact on the dam. The average phosphate levels entering the dam is 0.72 mg/L and the target to reduce algae growth is 0.15 mg/L. Various treatment options were investigated to solve the problem, but these efforts were mainly focused on treating the symptoms rather than the cause and treatment options were very costly. Legislation regarding water pollution this is in place, but is not enforced by government. The model predictions indicate that even if all WWTWs reach a zero discharge of phosphates, the required target will still not be met.
