Eric Smalstig, P.E.

Eric Smalstig is a Senior Principal Engineer based in California with more than 25 years of environmental consulting experience focusing on industrial facilities (production and waste management) assessment and remediation, Brownfields restoration for development, and surface water resource protection.


Eric focuses his practice in two areas: groundwater and vadose zone remediation and surface water resource protection. His experience in remediation includes conducting investigations of Brownfields and state and federal Superfund and hazardous materials sites; preparing feasibility studies; preparing remediation system designs and engineering cost estimates; construction and O&M activities; and regulatory negotiation and permitting.

He has been involved in more than 150 project sites along the West Coast involving Brownfields investigation and redevelopment, groundwater monitoring, hydrogeologic investigation, and water resource protection. Additionally, Eric uses his expertise in construction management to develop soil management plans, construction sequencing, and closure management plans for his clients.

With extensive experience with oil field operations, resulting impacts, and oil refinery sludge, Eric has managed several oil field environmental evaluations in Southern California including the extensive Bolsa Chica oil field, West Newport Oil Field, and oil field and production operation site investigations within the Ports of Long Beach and Los Angeles. These areas totaled approximately 3,000 aggregate acres of surface use for oil exploration and production activity. A portion of this acreage is being remediated as part of closure and alternative use development (industrial, commercial, and residential). Eric has successfully managed the oil field permitting process for air - South Coast Air Quality Management District (SCAQMD) and surface water - National Pollutant Discharge Elimination System (NPDES) to prepare and guide operations activities, and has also provided litigation support and expert consultation on environmental issues associated with oil field operations.

Using his experience with surface water resource protection and permitting, and with remediation processes, Eric has assessed the feasibility of various water quality best management practices, and designed large surface water quality improvement features (e.g., constructed wetlands, off-the-shelf and custom water quality treatment processes, and treatment trains). As part of implementation, Eric provides his clients with field and classroom training for technical, managerial, and operational staff on the issues related to surface water protection and permitting.
