The test bore holes are required to be done to comply with the latest legislation on contaminated land where a land fill site has been used over many years. Although the site at Castletown closed a number of years ago much more stringent European and Uk legislation now means that sites must be checked to find out if all is well below the surface. Checking a site does not mean that anything is wrong. It is in the first instance a health and safety measure and Highland council is required to supply a report on the Castletown site and other sites where they are close to housing. All councils are carrrying out similar checks on landfill sites in their area.
Once upon a time as a society we dumped everything but we now have to deal with that legacy. The bore holes are part of that checking. The Highland Council would be deemed negligent if it did nothing to protect the people of the region from harm.

There is nothing sinister in carrying out a check on the site. Bore holes are required to check for gas as this moves through the ground and with the correct samples and detection equipment an assessment can be made to determine if there is any or no risk. If there is found to be risk then some form of remediation may be required by a local authority. If nothing is found then nothing will happen until the next time it is checked.
Although these checks are something recent it would be as well to get used to them as they are here to stay and no doubt if you live near a disused quarry or land fill site you will see equipment being set up to carry out tests in the future. It is fairly new at the moment. Hopefully nothing will be found at Castletown and even if it is it will be dealt with. Nothing has changed at the site recently but we will not know until the results are published if there is anything going on underneath.
Undoubtedly as this type of action is new it gets a lot of publicity but it is precautionary rather than a signal that anything is wrong.
