Impact of Stormwater on the water quality of Blenheim's waterways 2016
Blenheim is the largest urban area in the Marlborough region. A number of streams flow through Blenheim, many of them spring-fed with naturally very clear water. Most of these streams flow into the Taylor River, which meanders through the central part of the town. The riverbanks form a popular reserve used for walking, biking and running.
As in other urban areas in New Zealand, stormwater is significantly impacting water quality in the stream and the Taylor River.
SEE Ltd were commissioned to collate and summarise water quality data collected as part of the Blenheim Stormwater Strategy. This Strategy was established to provide an inclusive, holistic and prioritised approach to managing Blenheim-wide stormwater issues.
Monitoring was carried out over a ten month period beginning on the 27 November 2013 and ending on the 7 August 2014. A total of 31 sites were monitored, comprising of rivers, springs, drains, ephemeral surface waters and stormwater outfall pipes.
