Phase I & II Environmental Site Assessments for Cold Storage Facilities in Vietnam
SLP Environmental conducted combined Phase I and Phase II Environmental Site Assessments (ESAs), supplemented by limited Environmental, Health and Safety (EHS) Compliance Reviews, for a portfolio of cold storage facilities in Hanoi, Vietnam. Supporting pre-acquisition due diligence, the studies assessed soil and groundwater contamination and compliance with key Vietnamese EHS regulatory requirements. The work combined site inspections, historical research, soil and groundwater sampling, laboratory analysis and permit reviews, with a separate report providing findings, recommendations and an environmental risk rating for each property.
The Phase I ESA assessments comprised of a site and environs reconnaissance, interviews with key informants, and desk study to determine the landuse history and the physical and biological setting at each Property. This enabled the development of a preliminary conceptual site model (CSM), and determination as to whether potential Recognised Environmental Conditions (REC) were connected with the Target Properties.
The Phase 2 ESAs comprised of an intrusive site investigation that targeted the likely release areas identified during the Phase 1 ESA. The scope of works included concrete coring, the rotary boring of soil bores and the installation of groundwater monitoring wells in each soil bore.
Soil and groundwater samples were recovered and submitted to an ISO:17025 accredited laboratory for analysis for a range of potential contaminants of concern (PCOC). The laboratory test results were compared with Thai and International Screening Values to determine the contamination status of the Properties. A wellhead elevation survey was also undertaken to determine the hydraulic gradient in the shallow aquifer underlying the Target Properties.
The EHS Compliance Review comprised of a review of permits and related documentation, observations made during the onsite audits and interviews with key personnel with responsibility for EHS performance.
The findings of each combined study were presented in a standalone Environmental, Health and Safety Due Diligence Assessment Report, which provided clear conclusions, recommendations and an overall environmental risk rating for each Target Property.
