24 In comparing the results (upstream of the abattoir discharge, TRC site code KHI000301) to the point below the abattoir discharge (TRC site code KHI000307), the outstanding features are the marked increases in ammoniacal nitrogen and dissolved reactive phosphorus concentrations. Both nutrients are greatly in excess of the levels recommended by the ANZECC water quality guidelines, and this is likely to contribute to the proliferation of algae in the Patea River, into which the Kahouri Stream flows (TRC, <strong>2006</strong>b). It should be noted that Ballance Agri-Nutrients Ltd also discharge stormwater to land in this unnamed tributary’s catchment. This discharge may also enter water. See Section 9.4.1.2 for the discussion of receiving water results related to this site.
