Canterbury DHB’s Community and Public Health unit has lifted its algal bloom health warning issued for Te Roto o Wairewa/Lake Forsyth.
Recent water testing at Te Roto o Wairewa/Lake Forsyth has shown the quantity of potentially toxic blue-green algae (planktonic cyanobacteria) in the lake has reduced and concentrations are now below levels that are of concern to public health.
Canterbury Medical Officer of Health Dr Cheryl Brunton says Environment Canterbury’s sampling of Te Roto o Wairewa/Lake Forsyth will continue on a monthly basis.
“The public will be informed if testing shows that concentrations have increased and there is a risk to public health again,” Dr Brunton says.
