UNDERSTANDING EXTRACTABLE PETROLEUM HYDROCARBONS and VOLATILE PETROLEUM HYDROCARBONS WATER TEST RESULTS The purpose of this informational handout is to help you understand petroleum test results for your drinking water. The Maine Department of Environmental Protection [DEP] relies on laboratory tests called EPH [Extractable Petroleum Hydrocarbons] and VPH [Volatile Petroleum Hydrocarbons] to test for the presence of gasoline or fuel oil in drinking water. These tests provide information needed to determine if drinking water supplies near petroleum spills are contaminated with petroleum above health-based guidelines. Feedback Requested:
