Foreshore glass came from Imperial Ground

Shards of glass littering the Exe Estuary, near the Imperial Recreation Ground, are the result of work carried out to try to shore up the former landfill site, district bosses have said.
In 2013, East Devon District Council spent £800,000 replacing the concrete revetment that circles the recreation ground – work designed to stop pollution leaking.
However, participants in a recent Exe Estuary clean-up found glass littering the foreshore, and district bosses have conceded that this came from under the recreation ground.
A council spokesman said: “In 2013, we spent £800,000 replacing the protective concrete mattress, which covers the old landfill site that lies beneath the Imperial Recreation Ground.
“Unfortunately, although we took every precaution we could to try to prevent glass leaching out from under the protective mattress while carrying out the work, some material did manage to escape.
“This was due to the vehicles on the foreshore shaking the soil and reducing its strength and stiffness (an effect called liquefaction), which caused some glass to be drawn up.
“We endeavour to keep control of these residual glass levels - which surface in varying quantities - through regular litter and glass-picking patrols.
“We have also used top soil to cap off the recreation field to try to contain glass material.
“It is not an ideal solution, but the alternative would be to dig up the whole site, which is not financially feasible.”
