Health Warning issued for Tauranga Harbour
With the heavy rain in the Tauranga urban area overnight there have been several reports of surface flooding and sewage overflow events with spillage into the harbour. Medical Officer of Health, Dr Neil de Wet, says that, “As a health precaution, it is advised that people should avoid swimming and other watersports and activities that involve contact with harbour water.”
Toi Te Ora – Public Health routinely recommends that people should avoid swimming in rivers, streams and harbour areas for 48 hours after heavy rainfall events. With the number of reported sewage overflow events in the Tauranga urban area bacterial levels in the harbour may take a little longer to return to safe levels. “We will be monitoring the situation, but at this stage I would advise against swimming in the harbour at least until after the long weekend or until the water sampling results show that the water is safe to swim in.”
Shellfish tend to accumulate viruses and bacteria and may remain contaminated for up to three months and so it not advisable to collect shellfish from near urban areas especially in the months after an event such as this.
I only just caught the notification on tonight's TV3 news. 4 small signs along Pilot Bay is apparently enough notice for all harbour users today. Would have been quite handy information to have had, prior to sculling a litre or two yesterday arvo! See post below.
"Councils from the Bay of Plenty up to the Far North say people should stay out of the water and not collect shellfish, because of sewage flowing into the sea.
"Some of the older parts of the network carry wastewater and stormwater, so if it rains, you can have a discharge if those pipe networks are overwhelmed with stormwater," says Grant Ockleston, Auckland Council stormwater manager.
It even caused a triathlon to become a duathlon, with organisers having to cancel the swimming stage of their race. But many beachgoers complained they hadn't noticed the small warning signs.
"You can make them as big as you like, but if people don't want to read them…" a Tauranga City spokesperson told 3 News. "We've got four signs along that beach - at the changing sheds and at the boat ramp. I think that we've got adequate signage."
