In the vicinity of the Project area, a few potential commercial and industrial developments were identified during the site surveys. These included abandoned poultry/livestock farms, a plant nursery, a non-operating industrial facility with an air emission stack, a police station with a dangerous goods store, and a pumping station for the Ping Yuen River. The potential land contamination risks of these facilities to the Project area were assessed and identified only one site (Site 4) required intrusive site investigation to confirm if the soil is contaminated. Based on the soil analytical results, it is concluded that there is no significant contamination at BH1. All results were below the respective RBRGs – Rural Residential for the parameters tested. As no groundwater was present at the sampling depth of 3 m (bgs), groundwater samples were not retrieved. There is no risk to humans from the handling of the excavated soil and therefore no further assessment or remediation of soil is required.

As the result of the above, no potential impact from the contaminated soil is anticipated
