Spot testing of creeks across South Langley and Surrey is the first step in reducing levels of bacteria that are affecting shellfish harvests downstream. On Monday, Feb. 6, Lisa Dreves of Langley Environmental Partners Society was out sampling from Langley and Abbotsford creeks that run south across the Canada-U.S. border into the Nooksack River. At a bridge in Otter Park off 248th Street, she flings an old plastic milk jug tied to the end of a rope into Bertrand Creek, hauling up about a litre of water. Smaller samples are poured into bottles for later testing. Meanwhile, another device dangled off the bridge checks the oxygen content and temperature of the stream, both important for fish.
