ENVIRONMENTAL MONITORING
EOHS through understanding of industrial processes, as well as statutory requirements, can provide the client, with efficient and cost-effective solutions for pollution concerns. However, problems can only be managed once they have been quantified. Therefore, EOHS offers a full range of environmental monitoring services. Monitoring services include the following:
Stack Emission Sampling
Point Source emission sampling is conducted to determine compliance and according to methodology stipulated in, Listed activities and associated minimum emission standards identified in terms of Section 21 of the National Environmental Management: Air Quality Act, 2004 (Act no. 39 of 2004). The following parameters are determined:
- Particulates (isokinetic)
- Gases
- Velocity
- Moisture
- Temperature
Soil Sampling
Soil sampling is conducted to determine the degree of chemical and/or microbiological contamination and to establish the necessity for rehabilitation. Analysis is performed by ISO accredited laboratories.
Water Sampling
Water sampling is conducted to determine the degree of chemical and/or microbiological contamination
and to establish compliance with Effluent By-Law standards.
Analysis is performed by ISO accredited laboratories.
The following are determined:
- Chemical analysis (organic and inorganic)
- Biological (Total microbial activity (TMA) and Legionella)
Fall Out Dust Sampling
Dust particulates in the ambient air are generated as a result of mechanical breakage such as grinding,
crushing and milling in addition to environmental factors such as wind, water and extreme temperatures.
Particulates in the environment can become suspended in the air again after settled dust is
disturbed by means of industrial activities or wind movement. Fall out monitoring is conducted at
strategic sampling points on the boundary fence of the site to quantify dust concentrations that
settle out under influence of gravity as a result of activities at the organization and those of neighboring
industries and to determine compliance with requirements of the National Dust Control Regulations promulgated
under the Air Quality Act no. 39 of 2004 – (Short Title: National Dust Control Regulations, 2013).
The following services are offered:
- Gravimetrical and filtration analysis
- Placement of samplers
- Compilation of sampling strategy
- Manufacturing of sampling equipment
Ambient Air Monitoring
Ambient air monitoring for criteria pollutants can be conducted at various locations to determine compliance with the National Ambient Air Quality Standards promulgated under the Air Quality Act no. 39 of 2004 and to verify air dispersion modelling predictions and projections. Long term as well as short term monitoring of the following pollutants can be performed:
- Gases
- PM10, PM2.5, TSP
