 Following a limits-based approach and with the help of monitoring
-networks, it would be practical to impose absolute limits for a variety
-of water health indicators. Whether a residual impact on the physical
-environment is significant or not then is a matter of setting measured
-trends against the expected level of the impacts of a proposed
-activity. In the case of the planned dairy factory, the significance
-of the impact of discharging warm water into the river not only
-depends on the absolute value of the temperature difference between
-wastewater and river water, but also on the cumulative temperature
-increase due to human activity reflected in the mean temperature of
-the affected body of water. Case studies can be used to estimate the
-magnitude of the impact. If the limit on water temperature would be
-exceeded by the plant's wastewater discharge, the impact would be
-rated as significant and in need of mitigation to avoid significant
-effects on the aquatic ecosystem. The same approach is applicable for
-any impact that affects quantifiable environmental properties, such as
-the release of organic and inorganic compounds, or the contamination
-with residual antibiotics and pesticides.  According to the
-description, the river is already used as a sink for the wastewater of
-another dairy factory; dairy farming is said to have expanded in this
-area, indicating that the inflow of organic and inorganic components
-from farm effluent and non-point sources has also increased. It is
-likely that under these circumstances, the cumulative impacts of
