E.coli levels dropping in Wairoa River


Swimming warnings remain in place at Wairoa River where an investigation is ongoing by Hawke’s Bay Regional Council and Hawke’s Bay District Health Board into recent high levels of E.coli contamination.

Hawke’s Bay District Health Board Medical Officer of Health Dr Nicholas Jones said that despite one sampling result showing levels had dropped back below guideline level warnings, people should still avoid swimming in the river.

“Our investigation is continuing, and the overall trend of Wairoa River is that it is continually graded as very poor and therefore is not recommended as a site for swimming and other recreation," Dr Jones said. 

“Faecal sourcing testing, which forms part of the joint investigation into the likely cause of contamination in the water, has been carried out and samples were currently being processed by a lab.”
