months. As a result the following roads needed extensive
repairs throughout the Spring and Summer. The roads affected by this
increase in forestry activity were, Soldiers Road, Kupe Road, Stanley
Road, Douglas North Road, and Mangapapa Road.
Other works of note were the repairs to McBrides Bridge on Mangaehu
Road. This bridge was damaged in a high rainfall event from flood
debris, see the photo below:

environment. Organochlorine pesticides and arsenic can leach
slowly down the soil profile and can contaminate groundwater.
The extent of leaching will depend on the soil type, with greater
leaching occurring in sandy soils. The amount of rainfall or
irrigation will also influence leaching of contaminants through
the soil. Leaching may mean that the highest concentrations
of contaminants are below the soil surface at some sites. Soil
contamination has been measured to a depth of five

2014/2015. Projects with clear benefit to Taranaki were identified
by Council staff and successfully advocated for: a review of a
national High Intensity Rainfall Design System (with benefits for
hydrology, river engineering and civil defence response), and
development of Discrete Water Quality Sampling Standards (SEM
and Policy/NPS-FW implementation benefits). The Envirolink

compared with the monthly rainfall totals. Rainfall figures are from the
rainfall recorder located at TRC, Stratford. 27
