5.2.1 Issue

The discharge of wastes and hazardous substances into or onto land can cause:

  1. contamination of soils with pathogens, heavy metals, pesticides, hydrocarbons and other persistent hazardous substances to levels that:
    1. present significant risks to human health or the wider environment
    2. reduce the versatility and productive capacity of the soil environment
  2. adverse effects on the significant characteristics of air quality
  3. contamination of surface water and ground water with substances such as nutrients, pathogens and persistent hazardous substances to levels that present risks to human health, aquatic habitats and the wider environment through processes such as surface run-off, acid drainage, leaching and ground water percolation
  4. downstream sedimentation increasing the rates of infilling of the Region’s lakes, estuaries, artificial watercourses, rivers, wetlands and cave systems resulting in loss of aquatic habitats, increased risk of flooding
  5. increased risk of flooding and land instability hazards
  6. adverse effects on the relationship that tangata whenua as Kaitiaki have with their taonga such as ancestral lands, water and waahi tapu.
