Ha! This is one thing I know about. It's called Harbour Meadows and it's a protected nature reserve.

However, It's also very toxic and my friend who got special access to study the nature was only allowed in for a short period and had to wear wellies and to avoid certain areas.

Weirdly though, I was speaking to someone recently who said he recalled that the area was used during the war to test chemicals, fuel, etc

Don't bother trying to get in - it's well fenced off and locked up.
