Public Health Assessment: San Jacinto River Waste Pits Channelview, Harris County, Texas.

摘要

The San Jacinto River Waste Pits (SJRWP) site, in the city of Channelview, Texas, consists of a series of three surface impoundments (pits) that were constructed on the west bank of the San Jacinto River near the Interstate -10 (I10) Bridge sometime between October 8, 1964, and February 15, 1973. Paper mill waste containing elevated levels of polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) were offloaded from barges into these pits sometime in the 1960s and 1970s. Since the pits were constructed, the pit area has subsided, and river currents have eroded the outer berm, allowing the two eastern pits to become partially submerged under a few inches to a few feet of river water.
