The free well water testing kits given out by the province to residents impacted by the recent wildfires do not detect hydrocarbons, but there are options if anyone suspects that type of contamination. Hydrocarbons are a large group of compounds that include fossil fuels such as natural gas and petroleum. It can also include home heating oil. Signs of hydrocarbon contamination include odours or an oily sheen on water or soil. If this is detected, the province recommends that people contact an environmental consulting company and ask to speak to an environmental site professional.
