A method and apparatus for treatment of waste material, for example waste material from an earth drilling operation. The waste material includes solids, fluids and contaminants, and is separated into a first material stream containing solids, and a second material stream containing fluids. Fluids are driven from the first material stream into the second for a fluid treatment process, which may include treatment to remove free oil, oil/water emulsions, dissolved hydrocarbons and heavy metals. The treatment process allows the treated solids and treated fluid to be discharged into the environment. The invention may be implemented on an offshore facility or marine vessel to allow on site treatment of drilling waste and discharge of treated material into the environment. Preferably contaminant monitoring and control systems are provided.
