Automatic timing includes controlling and actuating the date and time of day for taking a sample and the duration of the timing cycle, and relay means for closing and opening circuits connected electrically to timer contacts for energizing components of the waste water sampling. In one aspect, a tri-way valve passes a portion of waste water into a discharge pipe at all times and an electronic level control monitors and fills a waste water sampling container to a predetermined level. Contaminants include asbestos, and/or lead, silica dust, titanium dioxide dust, or carbon dust. Contaminated materials include woven and non-woven fabric, permeable and impermeable clothing.
