  • Will the equipment match the regulatory method?

    Anyone involved in field analysis of oil in water will con tinually get the question "Does your equipment match the regulatory method?" Zj While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory ...
