Evaluation of dioxin mobility and spoils leaching in a surface coal mine reclaimed with bleached kraft pulp and paper mill biosolids
- Mead Corp., Dayton, OH (United States)
A surface coal mine in southeastern Ohio has been reclaimed with approximately 15 to 25 cm thickness of biosolids from a bleached kraft pulp and paper mill wastewater treatment plant. Soil, vegetation, rodents, earthworms, insects, fish, frogs, sediment, and algae samples were collected and analyzed for 2,3,7,8-tetrachlorodibenzo-p-dioxin and 2,3,7,8-tetrachlorodibenzofuran. Water samples from lakes receiving drainage from unreclaimed and biosolids reclaimed areas were collected and analyzed for various parameters, including pH and metals. The trace levels of dioxin and furan in the pulp and paper mill biosolids did not bioaccumulate in rodents, insects, or earthworms or translocate into plants living in the reclaimed area. The trace levels of dioxin and furan in biosolids did not sufficiently migrate to a drainage lake to result in significant concentrations in fish, frogs, algae, or vegetation. The biosolids reclamation resulted in dramatic decreases in spoils leaching of acid, aluminum, calcium, iron, magnesium, manganese, nickel, and zinc. This work supports the thesis that surface mine reclamation with pulp and paper mill biosolids is safe and effective. 4 refs., 6 tabs.
