After the Blackwell Zinc Smelter shut down in August of 1974, the company work to clean up the site before "donating" it to the trustees of the Blackwell Industrial Authority, Glen Hadaway, Joe Cannon, Lawrence Youell, W.W. Rodgers, Jr. and F. Vassar Dyer. Those man then worked to clean up the rest of the site. Some of the old piles of debris were sold off to companies who could recycle the debris and extract the heavy metals present with in it. A company out of Oklahoma City, engineered a encapolation valut to house the remainer of the smelter debris present on the site. Worker removed the first 6 inches of soil from only half the site, and moved it to the pit. (Note that this act did not remove all of the smelter debris on the site, much of it is still there today.) Then they covered it with the soil from the bottom of the Jig Pond. The Jig Pond was were the water run off from the Zinc Smelter was collected. This area was just as toxic as the debris. According to new findings, the encapolation valut was not built to specics. This was also done under the oversite of the Oklahoma Water Resourses Board. They monitored the site up until the Oklahoma Department of Environmental Quality took the records from the Water Resourses Board. At that point any and all records of the site were lost. The only records of the site rest in the hands of the Environmental Protection Agency, and the City of Blackwell's personal engineer, Jim Willis. This is a fact, because his name is at the bottom of the drawn map to the location of the site. Yet with all that knowledge in the hands of the City of Blackwell, they still dug though the site to lay new sewer lines, and potentually harming its empolyees. This 5.5 acres site is home to 122,400 yd3 of Smelter waste.
