page Climate Taranaki is one of the sunniest and windiest regions in Aotearoa. Crowned the sunshine capital of New Zealand in 2021, New Plymouth often enjoys more than 2,500 sunshine hours a year. Taranaki climate is largely influenced by its location and exposure to weather systems migrating across the Tasman Sea. Consistent rainfall, a moderate climate and fertile, free- draining soils mean the region is well-suited to productive land uses such as
discharges, chemical monitoring of the stream found that although there were measurable changes in some parameters, most of these would have resulted in only minor transient effects at most. In terms of guidelines, there were a few low level exceedances of guidelines for pH, ammoniacal nitrogen, or biochemical oxygen demand. Zinc concentrations in four of the seven wet weather samples taken from the Waitaha Stream were found to be below the USEPA acute guideline for zinc, while five of the seven
highly variable as it would dependent on the weather conditions. Monitoring over the past two years has shown that the primary means of stormwater/wastewater discharge is via evaporation and soakage to land, as the Council has yet to observe the stormwater retention pond discharging directly to the Mangorei Stream. page 4 Photo 1 Stormwater sediment/retention ponds system 1.2.1.1 Stormwater All stormwater flows from within the site are directed to the retention pond

animal urine patches can be a major source of nitrate leaching. Dissolved Reactive Phosphorus (DRP) Phosphorus occurs naturally in rocks and minerals, and is commonly found in soils and sediments. Weathering of rocks and minerals releases phosphorus. In its soluble form, DRP provides an indication of a waterbody’s ability to support nuisance algal or plant growths (algal blooms), which is turn can impact aquatic ecosystems. Phosphorus binds strongly to soil particles,
the discharge points and mixing zones. General surveys of the entire industrial stormwater drainage system and the Mangati Stream are carried out in both dry and wet weather conditions. This involves sampling at up to 46 points (Figure 2), depending upon the weather conditions and the discharges occurring. The analysis of samples from these monitoring page 12 points includes a wide range of parameters, the particular number and type of which is dependent on the …

boundaries of the WWTP site appears to be governed largely by weather conditions. Odour is strongest under calm condition, when aerial emissions from the pond accumulate. This effect is accentuated when it is overcast, as vertical mixing with ambient air is reduced, and under warm temperatures, when odour-generating bacteria in the pond are most active. Effects may be exacerbated by reduction in aeration capacity (mechanical) in the pond and deterioration in the microfloral population of this pond.
