§ Mr. Denzil DaviesTo ask the Secretary of State for Wales (1) what was the evidentiary basis for the statement at page 64 of his Department's survey of contaminated land in Wales, August 1988, that certain areas of the site of the former explosives factory at Pembry, Dyfed are known to be contaminated with phenols and that some remedial measures have been attempted;
(2) what was the evidentiary basis for the statement at page 50, paragraph 6, Llanelli, of his Department's survey 213W of contaminated land in Wales, final report, March 1984, that certain areas of the site of the former explosives factory at Pembrey, Dyfed are known to be contaminated with phenols and that some remedial measures have been attempted.
§ Mr. Gwilym JonesThe surveys were based on desk studies using information from a range of reference sources. Detailed site surveys were not undertaken; instead, information on potential contaminants at individual locations was usually based on known past uses of the land and the materials normally associated -with those uses.
§ Mr. Denzil DaviesTo ask the Secretary of State for Wales (1) if he will list the categories of phenols which are known to his Department to be contaminating the site of the former explosives factory at Pembrey, as stated in his Department's surveys of contaminated land in Wales;
(2) if he will describe the remedial measures which have been attempted in respect of the phenols which are contaminating certain areas of the site of the former explosives factory at Pembrey as described in hs Department's surveys of contaminated land in Wales.
§ Mr. Gwilym JonesThis information is not held by the Welsh Office. However, as is indicated on page 15 of the report "Survey of Contaminated Land in Wales, March 1984", phenol in the soil normally dissipates as a result of leaching and natural degradation. This is something the sampling programme recently commissioned by Llanelli borough council can be expected to check.
