Our diverse client base includes many regional banks, governmental agencies, major U.S. corporations, commercial shopping mall developers and oil and gas companies as well as local business communities and private individuals. The quality of our work has resulted in our strong reputation with both the business and regulatory communities.
Phase I and II Investigations
An Environmental Site Assessment (ESA), or Phase I ESA, is an investigation that includes a thorough review of available state and local records, Massachussetts Department of Environmental Protection (MassDEP) documents and a field investigation. All research and findings culminates in a report that conveys a professional opinion as to the existence of hazardous waste disposal at the Site or threat of release of such materials. ESAs are generally performed in association with a real estate transaction, such as a sale or refinancing of a preperty.
The physical properties of soils have a dramatic impact on any construction project. Whether the project involves installation of a septic system, or delineation of a wetland a thorough understanding of the soil properties is a crucial element in the successful completion of those projects.
Atlantics range of subsurface investigations have included the identification of hydric soils, perc testing, and bedrock mapping. Atlantic's subsurface experience also includes soil and groundwater testing for Phase II Investigations to determine the presence of potential hazardous waste.
Installation and testing of groundwater monitoring wells is essential to analyzing and characterizing the contents contained in the groundwater at a site. Atlantic's manages all areas of a subsurface investigation including the site analysis and determination of testing locations, coordination for installation of monitoring wells, as well as soil boring and groundwater sampling and analyses.
Environmental Response Actions
The clean-up of known or suspected hazardous waste disposal sites is regulated in Massachusetts under Chapter 21E of the Massachusetts General Laws and the Massachusetts Contingency Plan (MCP 310 CMR 40). These regulations are enforced by the Massachusetts Department of Environmental Protection (MassDEP) and require that all site remediation proceed through a serires of phased investigations. These investigations document the progression of a contaminated site toward acceptable cleanup levels.
Atlantic has successfully investigated and remediated hazardous waste sites ranging from contaminated soil excavation and removal of leaking underground storage tanks (USTs) to more complex situations involving in-place soil and groundwater remedial activities.
Atlantic's mobile laboratory and team of trained scientists are on-call for any situation deemed as an Immediate Response Action (IRA) as defined by the Massachusetts Contingency Plan. Immediate Response Actions are assessment and/or remedial actions that are undertaken in an expeditious manner to address sudden releases, Imminent Hazards and other time-critical release or site conditions. Immediate Response Actions are taken whenever and wherever timely actions are required to assess, eliminate, abate or mitigate adverse or unacceptable release, threat of release and/or site conditions, as set forth in 310 CMR 40.0412.
Our staff of trained and certified Environmental Engineers and Technicians is experienced in all areas of Underground Storage Tank (UST) Management including permitting, installations, testing, monitoring, removals and replacements. Atlantic has performed Tank Services ranging from residential tank removals to gasoline service station installations to commercial UST testing and removals.
Atlantic specializes in the preparation and execution of Release Abatement Measures (RAM) at disposal sites where contamination is localized and in need of control. Release Abatement Measures are remedial actions that may be voluntarily undertaken by persons conducting response actions at disposal sites. The purposes of Release Abatement Measures are to remediate limited or localized releases, and/or to mitigate the impacts of larger releases until more comprehensive remedial actions can be instituted.
Groundwater and Soils Testing
Atlantic maintains a mobile environmental laboratory that is fully stocked with sampling equipment and contaminant monitoring instruments. Our mobile laboratory is equipped with an OVM 580B Organic Vapor Meter (OVM) PID, GeoTech Peristaltic Groundwater Pump, a 500 foot groundwater depth meter and an array of sampling bottles prepared with proper preservatives. Use of our mobile laboratory allows us to minimize analytical laboratory costs while allowing our professional staff to make informed decisions in the field.
Our staff of environmental engineers, scientists and technicians are trained in the proper sampling procedures and monitoring protocols. Through the use of our trained staff and mobile laboratory Atlantic has the capability to perform a wide range of on-site analyses and prepare samples for the formal analyses including Total Petroleum Hydrocarbons (TPH), Volatile Organic Compounds (VOCs), Extractable Petroleum Hydrocarbons (EPH) and Polychlorinated Biphenyls (PCBs).
Using an Organic Vapor Meter (OVM 580B) PID, Atlantic is capable of performing on-site headspace testing in order to determine the presence of volatile vapors in the air, such as those found in gasoline. Headspace testing can be used as a screening tool to determine the presence of volatile of contaminents. This DEP approved method is also effecive for determining the boundary of contamination during impacted soils excavation. Once PID readings determine that contamination levels are minimized or eliminated, formal samples are sent in to confirm that sufficient contaminated soils have been excavated for treatment.
Performing quarterly sampling events, whether commercial or residential, can add up over time and become costly to the client. Through years of experience Atlantic has streamlined soil and groundwater testing procedures leading to a decrease in final project costs. Atlantic is equipped with testing materials to sample a wide variety of target analytes and with the use of our mobile laboratory we are prepared to perform a sampling event on a moments notice.
Impacted Soils Management
One of the largest costs associated with removing impacted soils from a contaminated site is the transportation and disposal/remediation of soils. Whether the soil is taken off site or treated on site Atlantic, in conjunction with our associates, are capable of saving you money on every ton of disposed soil. Through long relationships Atlantic has the capability of receiving the best quotes for soil transportation and associated treatment or disposal.
Once the nature and extent of contamination of soil and groundwater is identified, remedial design alternatives are reviewed in terms of both effectiveness and costs to implement. Clean-up options are reviewed based upon required clean-up levels, technical efficiencies, long term liabilities and overall costs. The chosen remedial option is then detailed using the Massachussetts Contingency Plan process and organized in a submission to the Massachusetts DEP. Once approved in concept, detailed plans and specifications (performance standards) are prepared for the clean-up.
Remedial alternatives include soils excavation and disposal, vapor extraction (volatile's), encapsulation, bio-remediation, on-site groundwater pumping and treatment, carbon treatment, oil-water separation and other physical/chemical or biological treatment processes.
