Assessment environments: SAS is nationally and internationally known as an industry leader in aquatic ecological assessments in all freshwater environments including both lotic and lentic systems. In addition, SAS has undertaken work on estuarine systems.
SAS has undertaken numerous aquatic ecological assessments as far back as 2005 and over time has refined technique and presentation in such a way as to ensure the highest level of expertise which in turn leads to improved integration in the EIA process and easier decision making by both the proponent, the project professional team and the relevant decision making authorities with specific mention of the Department of Water and Sanitation. Additionally, SAS also facilitates aquatic biomonitoring programs with over 30 project locations being monitored on an ongoing basis. The following assessment spheres are highlighted with examples of prominent clients and clients listed on the JSE.
- Commercial and residential development (Attacq Investment Services, Advtech, Holdings, Century Development and M&T Development).
- Linear developments such as pipe (Drakenstein Municipality and Magalies Water) and powerlines (Private developers, mining, IPP’s and Eskom), roads (CSIR, SANRAL and Rustenburg Rapid Transport).
- Infrastructure development, including transit (PRASA), and sanitation (WSSA);
- Mining across all sub sectors and all regions of South Africa, Southern, East and West Africa from junior mining companies and small quarry operators to the largest diversified mining Companies (Anglo Platinum, Assore, Glencore Managed Operations, Pan African resources, Petra Diamonds, Wescoal, Keaton Energy).
- Industrial developments and facilities including the paper and pulp industry (Enstra Papers), chemical manufacturers (NCP Chlorchem) and cement production (Dangote).
Reporting: Aquatic biomonitoring reporting focuses on concisely presenting all data gathered by desktop methods, and databases along with the definition of the Present Ecological State (PES), Ecological Importance and Sensitivity (EIS), and other relevant aspects of aquatic resources using the most appropriate and industry recognised assessment tools as advocated by the DWS River Ecostatus Monitoring Program. SAS also undertakes Whole Effluent Toxicity (WET) as well as the Direct Estimation of Ecological Effect Potential (DEEEP) assessments to assess the possible acute effects on aquatic biological assemblages. Monitoring reports focus on Ecostatus Definition, spatial and temporal analysis, compliance to resource quality objectives and target water quality guidelines as well as classification and quantification of toxicological data.
