Hertfordshire Police has sent out a stern warning to people who have been visiting Pitstone Quarry, near Tring.
The quarry is not only on private land but is also very dangerous and poses plenty of risks for people who think it is safe to swim in.
If caught entering the land without permission from the owner, people could be prosecuted and the police could take action if it continues.
In addition to this, swimming in quarry water is dangerous.
Water temperature can be 80 degrees at ankle-deep and then 40 degrees at just below the surface – this can shock a swimmer’s system and they can quickly find themselves in danger.
The sides can be steep and are a mixture of clay, soft silt and gravel which can shift underfoot and can go at any time.
The water is also prone to dead animals and excrement which can cause disease, pollution and rubbish which can cause a number of problems for a swimmer and poisonous and toxic algae.
The location of the quarry makes it difficult for emergency services to access if someone needs assistance so police want to share this advice to those who have been visiting it or may be planning to in the future.
A parking suspension has also been put into place by Transport for Bucks.
Herts Police and Thames Valley Police will continue monitoring the area.
A spokesperson added: “Please, we ask kindly, do not visit Pitstone Quarry to enjoy the sunny weather – there are plenty of other lovely areas in Hertfordshire where you can enjoy this fine weather and socially distance, keeping yourselves and others safe. Thank you for your understanding.
“Entering this land without permission from the owner constitutes the offence of civil trespass, which the landowner could have you prosecuted for in a civil court of law.”
