Harpur Hill Quarry is a disused quarry on Harpur Hill, Derbyshire. It has flooded and became known locally as "The Blue Lagoon".[1] The attractive blue colour is from caustic chemicals in the stone. The quarry lake is a popular swimming spot, despite pollution and its pH level being 11.3, which is highly alkaline (ammonia is 11.5 and bleach is 12.6).[2] In 2013 the water was dyed black to deter swimmers,[3] but as of 2015 the water had clarified and the lagoon has its natural blue appearance again.[4] The water remained a lush blue until it was again dyed black in April 2016.[citation needed]
