GEM GROUP Inc.

What GEM GROUP Inc. does

GEM Group, Inc. is a privately held environmental consulting firm founded in October 2005 in San Bernardino, California, operating with approximately eight employees. The firm is certified as a minority and woman-owned small business (MWBE), a status that supports access to government set-aside contracts. GEM delivers a full suite of environmental site assessment, investigation, and remediation services — Phase I Environmental Site Assessment, Transaction Screen Assessment, Phase II Limited Investigation, Site Investigation, Remediation, Desktop Review, Peer Review, and Risk Analysis Review — all conducted under federal, state, and local regulatory oversight frameworks including CERCLA, EPA, CalEPA, DTSC, and the State Water Resource Control Board.

The underlying technology stack is built on recognized environmental assessment methodologies rather than proprietary software platforms. Service delivery is grounded in field sampling (soil, soil gas, groundwater), regulatory database review, and engineered remediation systems such as soil vapor extraction. A representative project involved operating a vapor extraction treatment system that removed 107 pounds of PCE and reduced contamination by approximately 98%, plus excavation and disposal of approximately 1,730 tons of contaminated soil at Site 33 of the Bayonet and Black Horse Golf Course, ultimately receiving DTSC closure for unrestricted land use.

GEM operates a sales-led, project-based professional services model. Revenue is generated on a fee-for-service basis through custom quotes; pricing is not publicly disclosed and contracts are often multi-year. The firm serves both private sector clients (property owners, developers, lenders, brokers, buyers) and public sector clients (government agencies), with a primary service territory in California and select project work across Nevada, Arizona, Tennessee, Kentucky, Georgia, the Carolinas, Alabama, Arkansas, Missouri, and Mississippi. Distribution is direct via website intake questionnaires, phone outreach, and professional networking through its principal, Professional Geologist Jen Moser.

Functional benefit

Products and services

• Phase I Environmental Site Assessment Identifies recognized environmental conditions from the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property; satisfies requirements for CERCLA landowner liability protections.
• Transaction Screen Assessment (TSA) Identifies potential environmental concerns from an existing release, a past release, or a threat of a future release of hazardous substances or petroleum products; does not qualify for CERCLA landowner liability protections.
• Phase II Limited Investigation Further evaluation of contamination presence or likely presence from recognized environmental conditions or data gaps identified in a Phase I, including soil, soil gas, and/or groundwater sampling and analysis.
• Site Investigation Additional investigation designed to delineate vertical and lateral extent of contamination based on Phase II results, generally conducted under regulatory oversight.
• Remediation Mitigation or removal of contaminants from soil, soil gas, or groundwater for protection of human health and the environment, including soil excavation and disposal, soil vapor extraction and treatment, groundwater extraction and treatment, or in-situ treatment.
• Desktop Review Evaluates data in Federal, State, and local regulatory databases and immediately available information to identify potential environmental risks.
• Peer Review Impartial evaluation of environmental documents prepared by others, assessing quality of work, adequacy of conclusions, recommendations, and proposed investigative or remedial actions.
• Risk Analysis Review One-page risk report prepared by an Environmental Professional with risk ratings from Low to High based on regulatory database review; useful for lenders, brokers, buyers, and pre-closing due diligence.
