Guernsey's new plant may stop chemicals entering water

A new water treatment plant at Guernsey airport could help prevent toxic chemicals entering the water supply.
Plans for the improved drainage system have been submitted to the Environment Department.
In 2002 a fire truck overturned at Guernsey airport and a chemical once found in the foam used by firefighters got into local water supplies.
Work is continuing to monitor the reservoir for traces of the substance known as PFOS.
It is to ensure levels remain within the limits for drinking water set by the UK.
Public Services is now planning to remove soil in the contaminated areas, as well as building a plant to treat surface and ground water from the airfield site.
It is part of essential repairs and maintenance on the airport runway and should be operational before the other construction work starts (from BBC)

Is it worth the millions that it will cost?

It might be if it WOULD prevent instead of MIGHT prevent!!!

Is it an alternative for the Airport Fire Brigade to change the substances they use to a biodegradable version? Might save millions!!!!!
