Paradise Lost – England’s Deceptively Inviting Blue Lagoon Is Now Black

It was known as England’s  Blue Lagoon and its tranquil turquoise waters really did resemble those of an exotic watery paradise, but the popular swimming spot located near Buxton, was actually a flooded former quarry and its alluring contents were almost as toxic as bleach. That didn’t seem to bother people who came here from all over the country for a quick dip, so authorities had no choice but to dye it black.

Seen from afar, the Blue Lagoon at Harper Hill looked like the perfect place to cool off on a hot summer day, but as the saying goes, appearances can often be deceiving. Not only was this abandoned quarry full of trash, dead animals and human waste, but its waters had a pH level of 11.3, almost as toxic as ammonia (11.5pH) or bleach (12.6pH). The shoreline was lined with warning signs stating the dangers swimmers would be exposing themselves to – skin and eye irritations, stomach problems, fungal infections, etc. –  if they entered the water, and yet for decades they chose to ignore these warnings, bewitched by the beauty of the lagoon. The attractive color of this place was caused by the surrounding limestone walls which leached calcite crystals into the water, turning it turquoise, and the high alkalinity came from calcium oxide, a by-product of the quarrying process left around the site. Fearing for their children’s safety, locals asked authorities to restrict access to the lagoon, but because it was located on private property, they couldn’t stop people from visiting. So they decided to make it less attractive instead.
