Contaminated Land Diagnosis, Characterization and Remediation

Futuris has a wide experience working in the characterization and remediation of contaminated soils with hydrocarbons and heavy metals in Costa Rica and Panama. In Costa Rica, our technical and regulatory knowledge let us follow up a contaminated ground situation with the environmental authorities, looking for an environmental solution without closing the business’ operations. Our primary clients with this service are manufacturing industries and gas stations. We have also specialized in applying bio-remediation in gas stations, which is an in-situ remediation technique that does not require to remove the soil.

 

OBJECTIVES

  • Establish the nature and extent of soil & groundwater contamination
  • Cost-effective risk-based contaminated land management strategies
  • Remediation strategies to protect human health and environment

TECHNIQUES

  • Phase II assessments (ASTM E1903, CONCAWE 2003)
  • Internationally recognized land contamination assessment methods
  • Soil & groundwater sampling & analysis by certified laboratories
  • Conceptual Site Models, hydrogeology characterization and vulnerability
  • Tiered Approach for contaminated land characterization (RBCA ASTM E2081, ASTM E1739)
  • Quantitative risk assessment models for human health and groundwater (e.g. HESP, CLEA, AERIS)

BENEFITS

  • Management of contaminated land investigation and remediation by Futuris
  • Risk assessment to identify cost-effective soil contamination
  • Leading edge, highly credible, skilled and experienced team

Key Projects Related to Contaminated Land

Phase II Evaluation

Category: Industrial Manufacturing

Phase II evaluation on a metallurgic plant due to historic sources of metal and hydrocarbons detected during Phase I. The investigation included Passive Soil Gas Screening and drilling of monitoring wells and soil borings to take soil and groundwater samples. The risk assessment showed that no remediation was required. A monitoring Plan was presented and approved by the Ministry of Health.

Soil Sampling Program for PCBs

Category: Government & Public Services

Soil sampling program for PCBs at eight electrical substations, within the framework of the implementation of the project “Integrated Management of PCB in Costa Rica” of the United Nations Development Program (UNDP). Sample location was defined based on previous studies and collection of samples was based on internationally recognized methodologies.

Phase II Evaluation

Category: Oil & Gas, Chemical

Phase II evaluation due to historical hydrocarbon sources in a petrol station in which soil drilling and monitoring wells were made to determine hotspots and the area of impact. Low risk to sensitive receptors. However, given refurbishment of the station, the Remediation Plan included an in-situ bio-remediation with a reduction of the concentrations in soil from 500 mg/kg to non-detectable in three months.

Bioremediation

Category: Oil & Gas, Chemical

Bioremediation of sand and water with hydrocarbons within a secondary containment of the fuel underground storage tanks (USTs) of a petrol station. Concentrations in water were successfully reduced from over 50000 μg/l to less than 100 μg/l, as required by the authorities.
