Working with Environment and Climate Change Canada (ECCC) to identify potentially hazardous shellfish growing waters along the B.C Coast, JO Thomas routinely collects more than 3000 marine water samples over 60 survey routes annually. Surveys measure introduced fecal contamination over a broad geographical area and identify and quantify pollution sources within shellfish growing areas.

Surface marine water samples from key sampling stations throughout coastal British Columbia are collected by very experienced JO Thomas field staff using high-speed RIBs,  float-planes, and specialized equipment according to strict temperature and timeline requirements for  delivery to  ECCC for analysis and reporting.
