❓ Hon Giz Watson asks about the depth and nature of soil contamination related to a geothermal system, specifically questioning if the system's piping will intersect the contaminated soil. The Minister clarifies the depth of contamination, identifies the contaminants, and confirms the piping will not intersect the contaminated soil due to its shallow placement.

I refer to the answer given to part (3)(b)(iii) of my question without notice No. 647 on 14 September 2010, and I ask -
(1) To what depth is the soil contaminated?
(2) What are the contaminants?
(3) If the contaminated soil is being removed to a depth of five to six metres, won’t some of the underground piping for the geothermal system pass through the contaminated soil?
(4) If no to (3), will the Minister please explain why not?

(1) After completion of the subdivision works, there will be three pockets of contaminated soil, extending from depths of 5 to 22 metres below ground level.
(2) Free-phase hydrocarbons.
(3 & 4) No, because the geothermal system piping is being built approximately 1 metre below ground level.
