Decontamination laundering facilities and methods are disclosed including a washer area (12), a filtering area (36) automatically monitoring and controlling cleaning fluid quality discharged to the environment, a clean area (2), automatic and controlling air quality in the washer area (12), in the filtering area (36), in the clean area, and as discharged to the outside environment, and apparatus and methods for automatically timing waste water sampling, exhaust air sampling, and containment area air sampling. Automatic timing (68) 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 various circuits connected el ectrically to timer contacts for energizing components o f the waste water sampling, exhaust air sampling, and containment area (8) air sam pling. In one aspect, a tri-way valve (60) passes a port ion of waste water into a discharge pipe at all times and an electronic level co ntrol (79) monitors and fills a waste water sampling con tainer (66) to a predetermined level. In one aspect, a first high volume pump (92) and membrane filter cassette (90) collects air samples f rom a containment area in the laundering facility and a second high volume pump (93) and membrane filtor cassette collectsair samples from a HEPA air filtration machine (36). Contaminants include asbestos, and/ or lead, silica dust, titanium dioxide dust, or carbon d ust. Contaminated material includes woven and non-woven fabric, permeable and imp ermeable clothing.
