Environmental and Geological Consultants
Statement of Qualifications
Aperio Inc. staff holds Registered Professional Geologist (#6532), Certified Hydro Geologist (#802), Preliminary Environmental Assessor and Asbestos Abatement certifications as well as many others. We recognize that training and certification is important to you and our business and therefore staff is continually updating classifications and receiving training.
We have extensive experience in all aspects of environmental investigation and remediation as outlined below.
GROUNDWATER RESOURCES
Our Certified Hydro Geologist uses geological and hydro-geological information to
analyze groundwater quality and quantity issues for water companies. Client services include laboratory analyses, well site geology during drilling and pump testing. Regional and site specific data is integrated with field results to create conceptual hydro-geological models. Well construction details are designed and implemented by C-57 license drilling contractors.
CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA) and
NATIONAL ENVIRONMENTAL POLICY ACT (NEPA) STUDIES
Both of these surveys involve in depth biological investigations of both flora and fauna at Sites undergoing development projects. We also perform initial studies, negative declarations, mitigated negative declarations, environmental impact reports and studies (EIR/EIS). Special emphasis is spent on crafting environmental commitments to reduce impacts and mitigations.
PHASE I ENVIRONMENTAL SITE ASSESSMENTS
A Phase I Environmental Site Assessment (Phase I) involves researching and reviewing historic and current records pertaining to a specific property in order to discern any current recognized environmental conditions or historically recognized environmental conditions. This process is guided by ASTM standard E1527. Often times these assessments involve the analysis of historic and current photographs, aerial photographs, as well as topographic maps. A Phase I will also search publicly accessible databases, review historic documents, and access environmental based government (local, state and federal) databases. The property typically undergoes a Site Reconnaissance, including interviews with property owners and adjacent property owners, to investigate conditions not documented by the methods listed above.
PHASE II ENVIRONMENTAL SITE ASSESSMENTS
A Phase II Environmental Site Assessment (Phase II) typically involves further clarification of the recognized environmental conditions, historically recognized environmental conditions or releases of contaminants discovered in a Phase I. Most often, a Phase II involves soil, water and/or air sampling to better determine the extent of the impact of the recognized environmental conditions.
PRELIMINARY ENVIRONENTAL ASSESSMENT
A Preliminary Environmental Assessment (PEA) is defined by the California Health and Safety Code as an investigation performed “...to determine whether current or past waste management practices have resulted in the release or threatened release of hazardous substances which pose a threat to public health or the environment.” The PEA is regulated by the California EPA, Department of Toxic Substances Control. Aperio Inc. performs soil, water and/or air sampling, which is typically involved in a PEA, and also completes mathematical calculations to estimate the potential threat to humans or the environment.
UNDERGROUND STORAGE TANK REMOVAL
Aperio Inc.’s primary role in Underground Storage Tank (UST) removal has been to analyze the soil and/or groundwater from the location of a UST. If contamination is found, then remediation plans are implemented and/or monitoring wells may be installed. UST removals typically are regulated by local government agencies (city or county), and/or one of the California Regional Water Quality Control Boards.
HAZARDOUS WASTE RELEASE REMOVAL AND REMEDIATION
With its Occupational Safety & Health Administration (OSHA) Hazardous Materials certification, Aperio, Inc. has been called upon to investigate, remediate and/ or remove hazardous material spills. This process involves soil and groundwater analysis, professional oversight, project management, and ensuring compliance with local, county, state and federal regulations.
