  • Land: Proper sealing of the boreholes, through a cement based backfill
  • Solid Waste: Important to select only contractor(s) that have good environmental record. State in contract requirements on special waste ponds
  • Noise, visual pollution and radioactivity:
    a) Application of hearing protection for the workers
    b) Noise barriers to avoid disturbances of residential areas
