Photo: FileThe algal bloom health warning for Lake Forsyth in Canterbury has been lifted. Canterbury District Health Board’s community and public health unit's recent water testing at Lake Forsyth/Te Roto o Wairewa has shown the quantity of potentially toxic blue-green algae (planktonic cyanobacteria) has decreased. It said concentrations are now below levels that are of concern to public health. Canterbury medical officer of health Dr Ramon Pink says Environment Canterbury’s sampling of the lake will continue on a monthly basis until October when fortnightly monitoring will resume. “The public will be informed if testing shows that concentrations have increased and there is a risk to public health again,” Pink said.
