“…In addition to leaching acid, oxidation of these materials results in volumetric changes which compromise fill stability and may lead to subsidence and pavement buckling (Pye and Miller, 1990). Finally, failure to establish roadside vegetation due to extremely acid soil conditions increases sediments and acid runoff from bare road banks (Miller et al, 1976 (Huckabee et al, 1975;Klapper and Schultz, 1995;Morgan et al, 1982;Nathan and Katz, 1969). Furthermore, the combination of visible pollution and adverse conditions for aquatic life limits recreational uses, such as fishing and swimming in surface waters .…”

Road construction through sulfidic materials in Virginia has resulted in localized acid rock drainage (ARD) that threatens water quality, fill stability, integrity of building materials, and vegetation management. The objectives of this study were: i) to develop a state-wide sulfide hazard rating map based on characterization of the geologic formations associated with acid roadcuts, ii) to estimate depth to sulfidic sediments in the Coastal Plain based on landscape relationships, and iii) to evaluate potential acidity testing procedures on diverse materials. Potential acidity by Soxhlet extraction and PPA were equivalent for 3 of 4 diverse samples.Average acidity and metal contents of leachate from Soxhlet extractors were correlated with acidity and metals of road drainage. Sulfide hazard analysis should be an essential step in the pre-design phase of highway construction and other earth-disturbing activities.iv

“…Highly carbonaceou.8 aaterials (rider coal, parting•, leona.rdite and carbona.ceoua aha.lea) have been attributed vi.th producing acidity upon oxidation. Acid production from carbona.ceou.8 aateriala baa been identified in overburden and abandoned coal apoils in Wyoming, Kew Mexico, Montana, Utah, Colorado and Texu (Bola and llaore, 1986;loon, 1986;Hagener, 1985;Boon and Saith, 1985;Piaher and Munshower, 1984;Miller et al, 1976;Arora et al, 1980). Sulfide minerals occur in significantly higher concentratioUB in the finer grained aedillentary rocka aaaociated with coala: roof ahales, floor aaterial and parting • (Arora et al, 1980;Valkovic, 1983).…”
