HOUSEHOLDERS have been told their gardens may be contaminated.

Officers from Hartlepool Borough Council told the residents of 97 properties at Seaton Carew that tests would have to be carried out.

The measure is necessary after higher than normal levels of zinc, arsenic and lead were found in samples taken from around the edge of a housing estate.

The homes affected are in Wainwright Walk, Wainwright Close, Hornby Close, Cowley Close and Lithgo Close.

Ian Parker, the council's acting director of neighbourhood services, has written to each of the residents.

In the letter, he said: "You may be aware the land upon which this estate was built was previously used as a storage area for pit props from the early 1900s to the 1960s.

"The props would have been treated with a preservative while they were stored on the site.

"A specialist environmental consultant has indicated that there is a possibility that this site may be contaminated and has advised that further samples from the whole of the site are required."

Residents are concerned about the potential effect on property prices and the health of children who play in the area.

A steering group, including a resident's representative and NHS managers, has been formed. Hartlepool council has applied for £100,000 from the Government to cover the costs of testing.

Drop-in sessions have been arranged for residents with queries to keep them informed.

One will be held today, from 9am to 4pm, at Bryan Hanson House, Lynn Street, in Hartlepool.
