 WALSH's client, ASARCO, needed a way to store and analyze voluminous data generated during years of site investigations at a mining Superfund site in Colorado. WALSH developed and maintained an extensive sample logging and tracking database for ASARCO that catalogued several thousand locations with multiple samples and multiple analyses. WALSH incorporated all data into a Geographic Information System (GIS) to facilitate integration of laboratory data with CADD maps and digital aerial orthophotography. A forensic geochemistry model using the data determined potential sources of contamination by metals; metal concentration contours were integrated with topographic and aerial photographic data and analyzed for potential fate and transport.

 The OEPC Environmental Management System (EMS) was developed to provide access to Geo-spatial data for environmental managers and decision makers. The EMS uses Geographic Information Systems (GIS) technologies to display and warehouse environmental data and attributes. The data is accessible to multiple users who need limited knowledge of GIS procedures To view a complete description of the OEPC EMS please click here (use back button to return.

 Walsh developed an On-line oil spill contingency plan to manage environmental data need for decision making during an oil spill or other incident. Walsh used the internet to make the information available to a global audience within the organization. Reports, contact information, equipment types and locations were included. Environmental data such as hydrology, vegetation and soil patterns were included to give an idea of potential environmental impact. Pipeline and well characteristics and capacities helped prevent possible incidents. Internal and external reporting was available on line enabling all parties to view information in real-time. The on-line oil spill contingency allowed for easy updates ensuring that everybody had up to date information.
