Kulshan Services is providing source control monitoring for the City of Lynden on Fishtrap Creek under contract with Welch Ecological Services. Monitoring is being conducted as part of the City’s NPDES Phase II permit requirements. The City's monitoring efforts are conducted in collaboration with Whatcom County and the Whatcom Conservation District. The project involves identifying sources of fecal coliform bacteria and ammonia contamination (an indicator of sewage and agricultural contamination) in stormwater from sources throughout the Fishtrap Creek drainage within the city limits of Lynden. The study also addresses DNA testing. The goal of the project is to determine if sources of contamination are within the City limits or the surrounding agricultural areas.
In 2016 services included a day of sampling with the sewage sniffing dog, “Crush,” a dry weather outfall inventory, and microbial source tracking using DNA analysis to differentiate sewage from other sources of bacteria. These additional methods provided data to help further characterize the sources of bacteria contamination throughout the Fishtrap Creek drainage within the city limits of Lynden.
