Blue-green algae levels have decreased, but increased vigilance is still recommended
Darmstadt. The water quality of the Prinz von Hessen quarry has improved significantly following the cooler temperatures in the second half of July. As the City of Darmstadt reports, regular measurements taken since last week have shown a consistently low level of cyanobacteria. Visibility is also now back above one meter. This places the water body in the "increased monitoring" category of the German Federal Environment Agency.
Bathers are still asked to remain cautious. Head of Parks and Green Spaces, Michael Kolmer, explains:
“I am very pleased about the improvement in water quality. However, it cannot be ruled out that the high summer temperatures in the coming days will again stimulate the growth of blue-green algae. The staff of the Parks and Green Spaces Department will continue to reliably monitor the water quality.”
Those swimming in the Prinz von Hessen quarry should continue to avoid swallowing water and steer clear of areas affected by algae. Blue-green algae can be identified by an intense greenish tint to the water or by streaks on the surface. A thorough shower after swimming is recommended.
