PROJECT DESCRIPTIONS

Licensed Site Professional Services – Industrial Facility
Confidential Client
Metropolitan Boston Area

OHI Engineering, Inc. provided Licensed Site Professional Services for an industrial facility located in the metro-Boston area. Services included groundwater evaluation for industrial degreasing compounds, assessment and remediation of heavy metal impacted soil including abatement of an Imminent Hazard condition, coordination with commuter rail for site access, and public involvement activities including the development of a Public Involvement Plan (PIP).

 

Licensed Site Professional Services – construction project
Paolini Corporation
Metro west, Massachusetts

OHI Engineering, Inc. provided Licensed Site Professional Services for construction of a wetland replication area associated with a roadway widening in the Metro west area of Massachusetts. The work involved sampling and analysis of the organic sediment used to construct the replication area. Detectable levels of certain heavy metals were identified in the sediment. The levels were compared with freshwater sediment criteria to determine if there was an ecological risk associated with use of the sediment for the replication area. Based on our evaluation, it was determined that the organic sediment needed to be mixed with a bank-run gravel material to avoid potential ecological impacts.
  Environmental Site Assessment

OHI Engineering, Inc. conducted an environmental assessment of property proposed for purchase by Fitchburg State College. The assessment involved recommendations regarding an existing 1,000-gallon underground fuel oil storage tank. An evaluation was prepared and submitted to Fitchburg State College.

 

Licensed Site Professional Services
Silver Lake School District
Massachusetts

During construction of an addition to the existing High School, soil and groundwater impacts associated with a former gasoline-containing underground storage tank were identified. The impacts caused construction issues relative to the installation of a portion of the storm-water control system. Due to the conditions encountered, notification of the Massachusetts Department of Environmental Protection was required and subsequent activities have been conducted as an Immediate Response Action (IRA) in accordance with the Massachusetts Contingency Plan.

OHI Engineering developed the necessary health and safety procedures to allow installation of the storm-water system to proceed thereby avoiding delay to the construction schedule. Assessment activities were conducted to determine the extent of gasoline impacts to the soil and groundwater at the project site.

A pilot test was conducted for design of a remediation system. High vacuum extraction was the chosen technology due to the presence of both soil and groundwater impacts in a relatively low permeability soil strata.

Regulatory Compliance Reports
Draka Cableteq USA
Taunton, Massachusetts

Draka Cableteq USA is a manufacturer of specialty rubber, PVC and silicon jacketed cables.  Jacket extrusion and curing requires the use of both contact and non-contact cooling water.  In order to meet discharge limits of the EPA National Pollutant Discharge Elimination System (NPDES) permit, recycling and treatment of the process water was required.

OHI Engineering was responsible for the design of a reverse osmosis treatment system to remove salts from the contact cooling water prior to recycling the process water.  Flow rates and water quality data were collected over a period of sixty days to ensure that appropriate data was used in the design.  OHI designed a new mezzanine for the equipment thereby minimizing floor space disruption.

A series of chillers and cooling towers were also installed to facilitate re-use of the process water.  Upon system completion, process water in all areas of the facility will be fully recycled.  Installation of portions of the exterior equipment required wetland delineation and permitting with the local conservation commission.
