Synopsis

In the Chief Executive’s 2020 Policy Address, multi-pronged land supply strategy is being implemented including reclamation in Tung Chung, the agricultural land and brownfield sites in New Development Areas (NDAs) such as Kwu Tung North (KTN) / Fanling North (FLN) and Hung Shui Kiu (HSK) / Ha Tsuen (HT). Hence, there is a high potential of contaminated land being encountered during site formation in these areas. Potential contaminated land has to be assessed properly and remediated before redevelopment in order to prevent unacceptable risks encounter by future occupants or users. 

There are mainly three types of land contamination in Hong Kong, namely, 

1. Marine deposit from reclaimed land (e.g., reclamation in Tung Chung);

2. Contaminated soil from historical and present land uses (e.g., HSK / HT NDAs); and

3. Natural occurrence of Arsenic (e.g., KTN NDAs).

Assessments and treatments are based on the type of contamination. 

In this webinar, an overview of management framework of the three types of contamination including, assessment and available treatment technologies including,

• Management Framework for Disposal of Dredged / Excavated Sediment

• Investigation and Remediation of Contaminated Land 

• Arsenic Assessment and Treatment

are presented with examples. In addition, exceptional cases of contaminated land treatment will be shared.
