David M. Bloom

Project Manager / Senior Environmental Geologist


     Professional experience consulting in the environmental geology field since 1990, currently a project manager assigned to support environmental projects for primarily U.S. Navy customers in the southern California region. Primary project management responsibilities included budget, task planning, coordination, and execution of site assessment and remediation projects at sites under state and local regulatory oversight. Project management typically requires planning data collection, executing sampling and analysis plans, and communicating data results in real-time and at the conclusion of the project. Types of projects include assessment of the nature and extent of contaminated soil and groundwater to comply with the Navy Installation Restoration Program, modeled after U.S. EPA’s CERCLA cleanup protocols, compliance with RCRA and storm water regulations, and underground storage tank assessment and cleanup. Some sites are under Cleanup and Abatement Orders by regulatory oversight agencies, Preliminary Endangerment Assessments for hazardous waste requiring a great deal of interaction, cooperation, and communication with local and state agencies. Such communication tools include the Triad website, email, and meetings. Communicating large amounts of data may benefit from data visualization in graphical format using, for example, Geographic Information System (GIS) tools. Where applicable, this position includes integrating GIS technology into project applications.

Responsibilities include close communication with customers to make sure project activities meet the expectations envisioned by the customer, frequent communication with oversight agencies and other regulators so that an acceptable conclusion may result with minimal difficulty and expense. As project manager, responsibilities include making sure project budgets are met, properly trained and experienced staff are assigned to field and office tasks, and project documents receive an appropriate level of quality control.

Project budgets ranged from $27,000 to $460,000 in 2004-2008.
