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
The unnamed tributaries on this site are generally small, clear running low energy brooks with silty beds, however with increased rainfall the suspended solids level can rise quite quickly as silt is stirred up from the beds and edges of the streams and is entrained in the flow. Overall the level of suspended solids indicates good water quality in the stream system. Apart from a slight comparative spike in conductivity levels in the results for June 2008 in the downstream sites, the

1987). The climate is generally mild, with relatively high humidity and fairly high, evenly distributed annual rainfall . Soils are volcanic and varied, and include deep ash soils, well-drained alluvial soils along rivers, and sandy soils near the coast. Slopes within the broader landscape around the potentially affected sites range from gently undulating to strongly rolling. The Waiwhakaiho River is a narrow, single channel river, typically 10-m to 30-m wide, set within a
Taranaki District Council, which operates the Eltham municipal wastewater treatment system located to the east of Eltham in the Mangawhero catchment, holds a resource consent to allow it to discharge treated wastewater to the Mangawhero Stream under high rainfall conditions only. The consent for the discharge of emissions into the air expired in mid 2011 and is no longer considered necessary. This report for the period July 2012 to June 2013 describes the monitoring programme implemented by the
