Monitoring Environmental Effects

New Zealand Steel’s Environmental Management System places great importance on its commitment to minimise any effects of taking or discharging water, as well as controlling the use of water. In order to fulfill this commitment, the company employs a rigorous monitoring programme with regular reports to the Auckland Council, as well as the involvement of independent environmental consultants.

A rigorous monitoring programme has been established by the water quality and the receiving environment and includes:

  1. Daily grab sampling
  2. Flow proportional composite sampling
  3. Biological monitoring in the mixing zone (the area where the discharged water mixes with estuary water)
  4. Continuous turbidity sampling
