1 8 th IASSC First Circular Welcome to the 8th International Acid Sulfate Soils Conference in College Park, Maryland, USA 2016 Conference July 17 23, 2016 Excursions July 17 and 22-23, 2016 Acid Sulfate Soils: Pathways to Exposure and Remediation

2 Organized by: Dept. of Environmental Science and Technology (ENST), Univ. of Maryland, College Park, MD Acid Sulfate Soil Working Group of the International Union of Soil Sciences (ASS WG) In co- operation with: United States Dept. of Agriculture - Natural Resources Conservation Service (USDA- NRCS) Department of Crop & Soil Environmental Sciences, Virginia Tech Univ. (VTU), Blacksburg VA Soil Science Society of America (SSSA) American Society of Mining and Reclamation (ASMR) Mid- Atlantic Association of Professional Soil Scientists (MAPSS) Virginia Association of Professional Soil Scientists (VAPSS) Organizing Committee Martin Rabenhorst, UMD ENST, USA Delvin Fanning, UMD ENST, USA Brian Needelman, UMD ENST, USA Maxine Levin, USDA- NRCS, USA Thomas Reinsch, USDA- NRCS, USA W.

When drained, or disturbed by development and construction, metal sulfides that have accumulated in the subsoil are gradually oxidized, giving rise to the acidification of soil and drainage waters, often with detrimental ecological consequences. If reclaimed for agriculture, these soils are commonly used for growing rice in the tropics. In temperate areas they are often drained more intensively, exposing sulfides to oxidation also in deeper horizons. These soils are impacted by change in sea level and climate events. Previous Conferences have been held in Wageningen, the Netherlands (1972), Bangkok, Thailand (1981), Dakar, Senegal (1986), Ho Chi Minh City, Vietnam (1992), Tweed Heads, Australia (2002), Guangzhou, China (2008), and Vaasa, Finland (2012). This conference will provide a forum for the exchange ideas regarding the origins, properties, management, classification and reclamation of Acid Sulfate Soils. We also hope to include components for the education of those less familiar with Acid Sulfate Soil issues and problems (including engineers, geologists, geographers, politicians/lawmakers, environmental control organizations and agencies and

3 the general public.) Three days will be designated for oral and poster presentations (July 18,19 and 21), as well as a mid- conference whole- day field tour (July 20). In addition, a one- day pre- conference tour and a two- day post- conference excursion will be arranged to destinations within the region. Conference Venue The 8 th IASSC will be held at the College Park Marriott Hotel & Conference Center, 3501 University Blvd E, Hyattsville, MD (301) , which is immediately adjacent to the campus of the University of Maryland in College Park. College Park is a Maryland suburb of Washington, DC, located 8 miles from downtown Washington, DC. Setting the standard for Maryland hotels, the College Park Marriott Hotel & Conference Center maintains a strong position for its Leadership in Energy and Environmental Design (LEED) as the first LEED- certified lodging in the United States and welcomes guests with accommodations that include VIP suites and 40,000 square feet conference space. The hotel provides free Wi- Fi access, and free onsite parking. Conference Tour and Excursions During the mid- conference tour (July 20) we will visit the Univ. of MD research facility in Upper Marlboro and also the Smithsonian Environmental Research Center (SERC) to view sulfide- forming processes in subaqueous soils and tidal marshes of Chesapeake Bay, and will then view both Active and Post Active AS soil in Eocene/Paleocene and Cretaceous sediments before concluding the tour with a cookout at the scenic Sandy Point State Park (near Annapolis) overlooking Chesapeake Bay. Several options are under consideration for the Pre- Conference tour (July 17) that would permit observation of dredge material deposition areas and viewing of active AS soils and remediation processes. Details will be finalized by the time of the 2 nd circular. The post- conference tour will be a two- day excursion (July 22-23) permitting participants to view sulfidic materials exposed in the Nanjemoy formation along the Potomac river and native American shell middens en route to the Richmond, VA area where AS soil problems associated with mining activities and highway construction will be seen. Friday night will be spent near Fredericksburg, VA which was the location of a number of important battles in the US civil war (Dec, 1862). On day two, additional active AS soil exposures associated with the Stafford regional airport and home site development will be examined before returning to College Park. The mid- conference tour is included in the conference registration; the pre- conference and post- conference excursions will be arranged at an additional cost to be announced in the 2 nd circular.
