The analytical data from Consol includes: pH, conductivity, saturation percentage, percent sand, silt, and clay, calcium, magnesium, sodium, sodium absorption ratio, boron, molybdenum, selenium, nitrate-nitrogen, arsenic, mercury, lead, zinc, iron, and manganese (AB-DTPA Extractable), acid- generating potential, sulfur forms, and total sulfur. The acid-generating potential (AGP) for these samples was calculated based on pyritic-sulfur percent.
