- Waterways will get worse – Commissioner After extensive studies by government and dairy industry, independent PCE reported poor-water quality is caused by the run-off of nutrients from farm land, which breeds invasive weeds, slime and potentially toxic algal blooms. Last summer, toxic blooms in the Hutt River killed several dogs.Already choked with weeds and algae, waterways will get even worse as the dairy industry continues to boom, the Environment Commissioner says. … Read More

Russell, Environment Portfolio, New Zealand Dairy Research InstituteThe dairy industry like other industries in New Zealand has come under increasing pressure to improve its environmental performance. The pressures for change in New Zealand havecome from changes in environmental legislation, trade negotiations and customers who are concerned about the conditions in which the product they are purchasing is manufactured. This article describes the effects of dairy processing operations on the environment, wastewater sources and characteristics, wastewater treatment, and air emissions.

While there have been some improvements in water quality resulting from increased stream fencing and greater use of irrigation for effluent disposal, N concentrations have increased as dairy farming has continued to intensify.
- Turning the tide on water pollution
With half of New Zealand’s lakes and rivers unsafe for swimming – and many beaches too – poor water quality is the most important problem facing their environment.
- Farming for Economic Resilience and Environmental Performance: Tomorrows Farms Today 2010-2013 To date most studies have considered single mitigations and the cost of change. An understanding is emerging that if significant reductions in net losses of nitrogen are to be achieved in sensitive catchments, it may mean farm system reconfiguration must occur.
- Update report on the original investigation – Water Quality in New Zealand: Understanding the science In March 2012, the Parliamentary Commissioner for the Environment released a report on water quality titled: Water quality in New Zealand: Understanding the science. The report focused on the three main freshwater pollutants: pathogens, sediment, and nutrients. The report differed from the Commissioner’s previous reports in that it contained no recommendations. Its purpose was to provide an accessible, educative guide to water quality science, to help inform public debate and assist decision making. This update report describes the response to the 2012 report, and explains how it has been used.
