SALEM Engineering Group, Inc., has been a leading provider in environmental consulting services for more than 15 years. SALEM’s staff of highly trained and experienced environmental assessors, field geologist and hydrogeologists have conducted thousands of due diligence assessments and remediation on many properties throughout the United States. SALEM continues to provide progressive, professional, and practical consulting services and offers straight-forward, cost-effective solutions to a wide variety of environmental issues. Our vision, coupled with our commitment to our valued clients, quality work, and exceptional standards, is the key to our history of success.

Our clients include Fortune 500 companies, developers, municipalities, and government entities that routinely utilize SALEM’s expertise throughout the United States on a repeat basis. Some of our due diligence and remediation services are highlighted here:

Phase I Environmental Site Assessment (ESA)

SALEM’s staff of highly trained and experienced environmental assessors has conducted thousands of Phase I ESAs throughout the United States.  A Phase I ESA is an integral part of any commercial real estate transaction that are routinely conducted as part of ownership transfers, sales, new mortgages or refinancing of commercial real estate in order to satisfy lender requirements, evaluate the existence of Recognized Environmental Conditions (RECs), establish the “Innocent Land Owner” defense under the Comprehensive Environmental Response Compensation Liability Act (CERCLA), improve the quality and value of real estate portfolios, or estimate potential remediation costs for purchase agreement negotiations and development plans. The scope of the Phase I ESA is conducted in accordance with the American Society for Testing and Materials (ASTM) Standard 1527-13 and the USEPA’s All Appropriate Inquiry (AAI) standards. The Phase I ESA is an important document that can protect the current property owner and prospective purchaser from environmental liability. The Phase I ESA will identify and analyze potential environmental risks associated with the subject property and area properties of environmental concern.

Phase II Environmental Site Assessment (ESA)

If necessary, a Phase II ESA may be initiated following the completion of a Phase I ESA. The purpose of the Phase II ESA is to evaluate the near-surface soil and/or groundwater to identify the presence of contaminants which typically include petroleum products, dry cleaning chemicals, pesticides, herbicides and heavy metals in the soil and/or groundwater beneath the subject property. The scope of the investigation typically includes a project-specific program of field sampling, chemical analysis and preparation of a final report.

Geophysical Survey

SALEM has conducted and managed hundreds of Geophysical Surveys in California and throughout the Western United States. A Geophysical Survey is typically conducted to identify the presence or absence of an underground storage tank(s) or other sub-grade structures, usually a result of environmental concern from a Phase I ESA, that was not confirmed with available information.

Groundwater Monitoring

The goal of groundwater sampling is to collect samples that are representative of in-situ groundwater conditions and to minimize changes in groundwater chemistry during sample collection and handling. Several different groundwater sampling procedures are commonly utilized across the United States; however, no single method or procedure is universally applicable to all types of groundwater monitoring programs. SALEM’s standard groundwater monitoring program includes:

Soil and Groundwater Remediation and Regulatory Agency Closure

SALEM’s approach to site remediation focuses on combining technical know-how with sound judgment to determine a solution-oriented approach to your environmental needs. We apply decades of regional experience to design remedial systems and implement solutions for sites with contaminated soil, soil vapor, and/or groundwater. Our ability to understand and interpret environmental regulations allows us to respond to your needs in a cost-effective manner. Rather than take a study-based approach that simply characterizes the problem, we focus on providing you with results that matter. SALEM’s experts have designed and implemented remediation programs for operating and closed sites including: refineries; metal plating facilities; chemical manufacturing and blending facilities; dry cleaners; gasoline service stations; shooting ranges; and numerous other commercial and industrial properties. Our turn-key approach toward remedial solutions includes:

Soil Management Plan Preparation and Implementation

The purpose of a Soil Management Plan (SMP) is to provide an approach for management of soil that has been impacted by constituents of potential environmental concern (COPCs) that may be encountered at a property when it is disturbed during construction or renovation. Soil that is encountered during grading or excavation that appears to be impacted, or is confirmed to be impacted with COPCs, must be segregated and managed according to the standards set forth in the SMP during construction. In addition, soil that exceeds applicable regulatory agency screening levels requires the identification of appropriate waste acceptance facilities, waste profiling, and removal from the subject property. Excavation and grading activities may also generate volatile organic compounds (VOCs) in ambient air that exceed air quality guidelines; therefore, notification and monitoring is frequently required when soil is disturbed during construction-related activities. Failure to prepare an SMP before construction-related activities begin can result in significant delays and unanticipated construction costs.

Underground Storage Tank (UST) Removal

More than 500,000 underground storage tanks (USTs) are utilized nationwide to store petroleum-based products or other hazardous substances. The greatest potential threat from a leaking UST is contamination of groundwater, the source of drinking water for nearly half of all Americans. Releases from USTs can also result in human health risks due to inhalation (including indoor air risks from exposure to volatile constituents) and ingestion/absorption (due to contact with contaminated soils). Older USTs were historically constructed of steel, which has a tendency to corrode and leak over time. Tanks installed in the 1990’s were typically constructed using fiberglass or fiberglass-coated steel with secondary containment for additional leak protection. Today, state and federal regulations are in place to ensure that USTs are registered when they are installed, and document that the USTs are regularly maintained to minimize risks to human health and the environment.

Vapor Barrier Design

Volatile organic constituents (VOCs) in subsurface soil and groundwater can migrate upward through the soil, enter into buildings, and expose building occupants to unacceptable human health risks.  The most common VOCs are associated with aromatic compounds found in gasoline, chlorinated solvents used in metal cleaning or dry cleaning processes, and methane gas originating from landfills or abandoned oil fields.
