Surface mining is important to our modern way of life and to coal mining in the United States of America. Unfortunately old and new surface mining sites produce a metal-rich acidic solution termed acid mine drainage (AMD), which contaminates water and soil. Acid sulfate soil is unstable and prone to erode, and spreading this acidic sulfate-rich liquid across mine sites may increase the amount of AMD that can be generated. The current study focused on evaluating two affordable passive treatments of AMD and AMD-impacted water which could be used together to construct a semipermeable membrane for erosion control of acidic soils, immobilization of heavy metals, and to increase the pH. The first treatment was the land application of an inexpensive industrial by-product, drinking water treatment residuals (WTRs) to treat AMD with its alkalinity and metal binding affinity. The second treatment, intended for placement behind the WTR to clean metal-contaminated water and provide erosion control was the perennial grass, sunshine vetiver (Chrysopogon Zizanioides ). Sunshine vetiver is fast-growing, non-invasive, extremely tolerant of adverse AMD conditions, and a hyperaccumulator of some metals. In this experiment, all the sunshine vetiver grasses were able to grow in the practical mixtures of WTR and AMD-soil considered. With exposure to acidity the investigated WTRs released greater amounts of toxic heavy metals, the RCRA8 metals and aluminum, than ideal for use as a soil amendment on AMD sites.
