Phase 2 Environmental Site Assessment

Phase 2 Environmental Site Assessment

Chemical Production Facility, Thailand

SLP Environmental was appointed to conduct a Phase 2 Environmental Site Assessment (Phase 2 ESA) at an operational chemical production and distribution facility located in Samut Prakarn, Thailand. The study was conducted in accordance with practice presented in ASTM E1903-11 and the primary objective was to establish the contamination status of the soil and groundwater underlying the target property. The Phase 2 ESA was instructed by a potential purchaser of the facility as part of the pre-acquisition environmental due diligence process.

The Phase 2 site investigation scope of works comprised of i) a review of the Phase 1 ESA for the subject property, ii) the design of the site investigation, iii) the drilling of seven soil bores, iv) the installation of five temporary groundwater monitoring wells, v) the sampling and laboratory analysis of recovered soil and groundwater samples for a comprehensive suite of chemical parameters at a ISO17025 accredited laboratory, surveying of borehole positions and wellhead elevation and, vii) the decommissioning of the bores and wells and like for like reinstatement of property surfaces.

The soil and groundwater test results were compared with Thailand and international quality standards for an industrial landuse to assess whether the recorded ground conditions represented an unacceptable risk to human and/or environmental receptors.

The study culminated in the production of a Phase 2 Environmental Site Assessment Report that included a qualitative risk assessment for each identified potentially vulnerable environmental receptor, an environmental risk rating for the subject property and a determination as to whether any recognised environmental conditions (RECs) were associated with the property.

The report appendices included site plans and relevant figures, engineering logs, well construction details, field monitoring data, chemical test results and a full photolog of the works.
