2030, and 90% no later than 2040. This report gives effect to Policy A6(b) requirements of the National Policy Statement for Freshwater Management (NPS-FM). Background Taranaki has over 500 named rivers and streams, many of which contain spots or places valued for swimming. However, water quality in the region, as in other parts of New Zealand, varies dramatically with the weather. Taranaki’s high rainfall means that even our cleanest waterways may exceed recognised

irrigation areas were found to be working well, however during the September inspection it was noted that care needed to be taken when irrigating after rainfall as this increases the likelihood of ponding. 2.1.2 Results of abstraction and discharge monitoring 2.1.2.1 Waingongoro River abstraction Process and operation water for the site is pumped from the Waingongoro River, which is located 7.2 km east from the Company site (Figure 1). Water is pumped at a rate of approximately 140 m3/h
cell of the secondary pond (using chlorophyll-a measurements) indicated that the system had a low algal content, particularly following heavy rainfall events. Microfloral populations have not indicated poor performance of the treatment system to date and generally indicate an improvement in conditions in the tertiary cell since the last WWTP upgrade. Screening of the outlet from the secondary oxidation pond was well maintained. The inlet system functioned as designed during the monitoring

Zinc- acid soluble Zinc- dissolved page 16 In the previous May 2016 survey, suspended solids were very high (310 g/m3). The exact cause of this result could not be identified but was likely due to rainfall and/or activities in the headwaters of the stream. The results of the January 2017 and June 2017 surveys show very low suspended solids in comparison (Table 4). There was a slight decrease of zinc by 0.071 g/m3 between site upstream 2 and the downstream site (0.255
