The 38-acre Midland Products site is located near Ola, Arkansas. Old Midland Products operated from 1969 to 1979 as a wood-preserving treatment plant. A saw mill operated at the site as early as 1960. Wood-treating operations used creosote and pentachlorophenol (PCP). The company discharged contaminated effluent into waste lagoons, which occasionally overflowed. Following construction of the site�s remedy, operation and maintenance activities are ongoing.
