Regional targets for swimmable rivers and lakes for the Taranaki region

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

Stratford wastewater treatment plant monitoring report 2018-2019

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

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

expired on 1 June 2011, but remained in force while application for a new consent was being processed. There were eight conditions associated with this consent which set out how the consent shall be operated and managed. Condition 1 was a review provision. page 12 Condition 2 set out the terms of use of the consent during heavy rainfall only. Condition 3 set limits on the components of the discharge. Conditions 4 and 5 placed limits on the concentration of
