Investigation of alkaline mine drainage impacted streamside soil composition for select metals using extraction and acid digestion techniques
- Saint Vincent College, Latrobe, PA (United States)
The concentrations of Fe, Mg, Mn, Na, Ca, Zn and P were determined in soils that are adjacent to alkaline mine drainage impacted Four Mile Run in Latrobe, PA. The hypothesis stated: soils closer to the mine drainage win have higher extractable and total metal concentrations in an eroded zone closer to the stream than soils in an uneroded zone farther from the stream. Since the area will sustain enhanced and man-made wetlands, it is necessary to determine the bioavailability of nutrients to plants. A comparison was made of extractions, which mimic plant roots, and digestions which give total metals. The extraction technique is the Mehlich Method, and the digestion technique is EPA SW-846 method No.3050A. The samples were analyzed on the Inductively Coupled Plasma Spectrophotometer. The results show no difference between extractable metals in erosion and uneroded zones. This study will also provide valuable information as to the fertility and cation exchange capacity of these soils.
