AQUATIC BIOMONITORING & TOXICOLOGICAL ASSESSMENTS:
Known nationally and internationally as an industry leader, SAS has vast experience in conducting aquatic ecological assessments in all freshwater environments, including wetlands and estuarine systems.
SAS has undertaken freshwater studies since 2003, refining techniques and presentation of data over time to ensure improved integration in the EIA process, enabling efficient decision-making by all stakeholders.
In addition to conducting freshwater studies, SAS facilitates ongoing aquatic biomonitoring programmes in over 30 project localities throughout South Africa.
The following sectors are highlighted with examples of prominent clients and listed companies.
- Commercial and residential development (Attacq, Advtech, Century Development, Cosmopolitan Developments, Central Development, and M&T Development).
- Linear developments such as pipe (Drakenstein Municipality and SASOL) and powerlines (Private developers, mining, IPP’s and Eskom), roads (CSIR, SANRAL, ACSA and Rustenburg Rapid Transport)

MEET OUR TEAM
Stephen van Staden
SACNASP REG.NO: 400134/05
Stephen van Staden completed an undergraduate degree in Zoology, Geography and Environmental Management. He then undertook an honours course in Aquatic health. In 2002 he began a Master’s degree in environmental management, including his mini dissertation in the field of aquatic resource management. Stephen began building a career at a firm specialising in town planning developments, after which he moved to a larger firm in late 2002 where he managed the monitoring division and acted as a specialist consultant on water resource management issues and other environmental processes and applications. In 2003, Stephen started consulting independently specialising in water resource management. In addition to aquatic ecological assessments, clients enquired about terrestrial ecological assessments and biodiversity assessments, which developed into a very significant part of the business. Stephen started working in the wetland consulting arena and has become recognised as a national expert in this regard combining science (ecology and hydrology), engineering principles and an in-depth understanding of the legislative framework to provide turnkey advisory services. Stephen has launched soil and land capability assessment and visual impact assessment services with other specifically qualified specialists. Stephen is registered by the SA RHP as an accredited aquatic biomonitoring specialist and is also registered as a Professional Natural Scientist with SACNASP in the field of ecology. Stephen is also a member of the Gauteng Wetland Forum, the South African Soil Surveyors Organisation (SASSO) and IAIA.
Dionne Crafford completed an undergraduate BSc degree in Ecology in 1996, as well as an honours degree in Zoology in 1997. In 1999 he commenced with his MSc in Zoology on the use of fish health and parasite fauna as an indicator of water quality, and obtained the degree in 2000.
From 2001 he was employed as a parasitologist (veterinary researcher and later specialist veterinary researcher) at an animal health company, after which he moved to an animal health contract research organisation (CRO) in 2006. Here he was employed as researcher and later study investigator. In 2009 he started his part-time Zoology PhD studies on the monogenean parasite fauna of fishes in the Vaal Dam, which included description of a number of new species.
