Envitech has a proven background in the development and compilation of Environmental Management Plans (EMPs), pollution control systems, rehabilitation and mine closure plans. The various plans also identify the ongoing monitoring activities required, particularly in the case of active mines or during the aftercare phase for closed mines.

Envitech can assist with the following:

Site Investigations

• Geotechnical investigations including soil sampling and laboratory testing
• Groundwater investigations including borehole drilling, water sampling and laboratory analyses
• DTM modelling of surface and underground features

Design of Closure & Rehabilitation Measures – including geometric design (shaping), runoff paddocks and capping systems for

• Tailings dams
• Discard dumps
• Surface subsidence over undermined areas
• Closure assessments including removal of infrastructure

Groundwater

• Installation of groundwater boreholes and monitoring systems
• Development of sampling and monitoring protocols
• Review of laboratory analyses and trend reporting
• Reviewing the monitoring results and making appropriate recommendations

Stormwater Management & Pollution Control

• Storm water catchment analyses and runoff calculations
• Design of storm water drainage, storage and management systems
• Design of clean and dirty water management systems including drainage, pollution control dams, silt traps, slurry dams, geosynthetic lined dams and lagoons.
• Design of remediation systems for contaminated soils and water

Auditing and Annual Inspection Services

• Clean and dirty water management systems
• Rehabilitation and closure programmes
• Remediation systems for contaminated soils and water
• Feedback of audit results is provided to management

Construction Quality Assurance (CQA)

• Earthworks construction in accordance with SANS1200
• Geosynthetic liners in accordance with SANS1526, SANS10409 and GRI GM13
• Electric leak location surveys
