More detailed soil sampling is to take place as part of an ongoing investigation into potential airborne pollutants released from Hillhouse Technology Enterprise Zone (the former ICI site) in Thornton
In July, Wyre Council launched an investigation into the historic use of a chemical called Perfluorooctanoic Acid (PFOA) by AGC Chemicals Europe Ltd between the 1950s and 2012. The investigation is being carried out by the Environment Agency and supported by partners, including Wyre Council.
The initial phase of sampling confirmed the presence of the chemical PFOA at all 22 parcels of land sampled near to the site. Some of the results obtained are above relevant screening values for certain types of land use; specifically, the growing of produce. While elevated concentrations of PFOA are not necessarily a concern, the results highlighted the need for a more detailed study to be undertaken.
Now, a number of locations have been selected for further soil sampling by the Environment Agency according to a grid-based pattern covering the local area.
This grid-based pattern is designed to provide the detailed level of data needed for a robust and scientific risk assessment. Residents and landowners whose properties have been selected have received a letter from Wyre Council about this next phase of the investigation.
Councillor Michael Vincent, the Leader of Wyre Council, said:
"The initial phase of sampling was designed to confirm whether the chemical had been deposited onto surrounding land after it was released into the air by AGC Chemicals Europe Ltd. It was the first stage in a lengthy and complex investigation.
"Experts at the Environment Agency now need more detail to be able to undertake a risk assessment which will look at the level of PFOA found in the soil and the way the land is used.
"Our thanks go to the community for the help and assistance they have provided since the investigation was launched. We will continue to share information as soon as we can.
“The properties and land to be tested have not been selected because they have any increased risk or cause for concern, but using a scientific grid system developed by the Environment Agency. If residents who receive a letter are concerned they can contact us.
"We ask that as many residents and landowners as possible agree to take part as this will help the EA carry out the most comprehensive risk assessment possible”
Soil samples have already been collected from Sandringham Avenue Allotments while Occupation Road Allotments, which border the Hillhouse site, have also undergone further sampling.
It is hoped this second phase of sampling will be completed by the end of March.
