Julianna Connolly, LSP

Julianna Connolly is a Senior Principal Engineer based in Massachusetts with more than 14 years of environmental consulting experience focusing on risk-based closure for contaminated properties, human health risk assessment, vapor intrusion assessment and mitigation, and environmental due diligence.

She manages Geosyntec's New England operation and consults for clients with responsibility for industrial facilities, solvent releases, petroleum releases, and former manufactured gas plants.

A Licensed Site Professional (LSP) in Massachusetts, Julianna has managed the investigation, remediation, and regulatory closure of multiple sites under the Massachusetts Contingency Plan (MCP) and has completed hundreds of human health risk assessments under the MCP and other regulatory programs. Many of these sites have included evaluations of exposure to constituents in indoor air that have migrated into on-site buildings as a result of subsurface vapor intrusion.

Julianna is experienced in negotiating investigation and closure approaches with state and federal regulators, designing sampling plans to support site closure, and developing risk-based closure options. She has worked on brownfield redevelopment projects and has prepared many Activity and Use Limitations (deed restrictions) to mitigate potential future human health risks at impacted sites.

Through her work in the assessment, remediation, and regulatory closure of contaminated properties, Julianna has the experience necessary to support clients' business decisions associated with mergers, divestitures, and acquisitions. 

Her undergraduate degree in chemistry gives her the background necessary to evaluate the precision and accuracy of analytical data collected during environmental investigations and used to support risk assessments and closure documents for contaminated sites.  She is an active participant in Massachusetts Department of Environmental Protection (MassDEP) external workgroups relating to regulatory revisions to the MCP and preparation of guidance documents for vapor intrusion assessment and Activity and Use Limitation implementation.

Julianna currently serves as the LSP-of-Record for multiple industrial, institutional, and development clients throughout Massachusetts.
