Canterbury District Health Board’s Community and Public Health unit has lifted its algal bloom health warning issued for the Otukaikino/Waimakariri confluence near SH1 and Main North Road bridges
Recent cyanobacteria surveying of the water in the Otukaikino/Waimakariri confluence has shown the quantity of potentially toxic blue-green algae (benthic cyanobacteria) in the river has decreased and the cover is now below the levels that are of concern to public health.
Medical Officer of Health, Dr Alistair Humphrey says Environment Canterbury’s surveying of the Otukaikino/Waimakariri confluence will continue to the end of this summer and then will resume next summer when there is increased likelihood of cyanobacteria growth.
