his capstone project is an effort to determine whether airborne lead produced during the For Ord Reuse Authority's, (FORA) Deconstruction Project will pose any danger to neighboring receptors. Working with the Monterey Bay Unified Air Pollution Control District, (MBUAPCD) and FORA, I created a GIS project depicting Fort Ord and neighboring regions. It is to be used as an analytical tool in determining possible lead exposure risk to the public produced during the removal of structures from the former Fort Ord. The project will also serve as an aid in FORA's Deconstruction Project, which is a full-scale effort to remove structures and clean up hazardous materials while diverting valuable building materials from the local landfill. The project will be used as a communication and record-keeping tool during the 3-5 year building removal project. Included in the final project are the following GIS layers: a Digital Ortho Quad (DOQ), a Digital Elevation Model (DEM), buildings, roads, and parcel ownership with attached attribute data, and results from an ISCST3 (EPA standard) air dispersion modeling program. In addition, interpolation analysis of the modeling data and combined risk from multiple sources has been performed to show the overall concentrations of the lead. All of this data has been manipulated to display in an accurate and comprehensive manner in ArcView. From this information, exposure levels are evident and receptors are identified. The data used to input the ISCST3 model was acquired from preliminary testing on a Pilot Deconstruction Project. The numbers used in the model were the worst-case scenario results and do not represent actually concentration levels. Additional studies need to be made to determine initial lead content for more accurate modeling to be done. At this point, it is undetermined what levels of lead concentration will be suitable to the Air Resources Board. When satisfactory data is released on lead content and specific numbers of acceptability are implemented, the model will be able to clearly determine whether an area is within compliance.
