The state of Mid Canterbury rivers is nowhere near as bad as has been made out, a retired Methven farmer says. And he’s taken water samples and paid for their testing himself to prove his point. Ray McIntosh said he had got tired of reading stories that implied Mid Canterbury rivers were in a bad way, without anyone in those articles providing evidence to show why that was the case. So on July 19 this year, after a period of heavy rain and what he anticipated

would be a corresponding run-off from farms in the area into waterways, McIntosh took samples from the Mt Harding Stream and the Selwyn River. The Mt Harding Stream sample was taken from near the intersection of the Methven Highway and the Braemar Lauriston Road, just before where the stream enters the Ashburton River, while the Selwyn River sample was taken near the bridge on State Highway 1. Both samples were taken using water testing packs supplied by Ashburtonbased CFA Laboratory and McIntosh said he followed advice provided by the

company on how to take an accurate sample. According to the resulting reports from CFA, the Mt Harding Stream sample showed a nitrate reading of less than its detectable level of 0.5mg per litre, while the Selwyn River sample showed a nitrate level of 1.2mg/l. The maximum acceptable level permitted by the New Zealand Drinking Water Standards is 11.3mg/l.
