Soil treatment will lay clean ground for Loop
I refer to your editorial ('Toxic wasteland hardly the place for universities', November 30).
We share your views that the Lok Ma Chau Loop provides opportunities for 'facilities that can house the latest technologies' and 'academic exchange and research with mainland academia'. It is also our vision to develop the Loop as a green hub for higher education, research and development, and creative industries.
We hope that our proposed planning scheme will generate not only synergy within the Loop but also add vibrancy to this area through its proposed links and connectivity with Shenzhen to its north and the Northeast New Territories New Development Areas to its south.
Contaminated mud dredged from the Shenzhen River during the training of the river in the 1990s had been deposited on the Loop. One of the priorities of the ongoing Planning and Engineering Study on Development of Lok Ma Chau Loop is to carry out a comprehensive investigation of the condition and extent of the deposited mud.
Based on current study findings, there are five isolated spots, all very close to the old Shenzhen River meander, at which the metal 'arsenic' slightly exceeds the limit stipulated in the Risk-based Remediation Goals for Contaminated Land Assessment and Remediation promulgated by the Environmental Protection Department.
A statutory environmental impact assessment is being conducted. Subject to the findings of the final EIA, we plan to use well-established solidification/stabilisation methods to treat the contaminated soil on site. After remediation, the Loop will be no different from any other 'clean' land suitable for development.
