Hamburg Sees Second-Wettest Year Since 1881, Boosting Groundwater Levels

Record rainfall in 2023-2024 improves groundwater reserves, while new EU water regulations target pollution control.

Hamburg experienced 1,050 millimeters of rainfall from November 2023 to October 2024, marking the second-highest annual total since records began in 1881.
Groundwater levels in the city have significantly risen, reversing a downward trend from previous years, with deep aquifers showing notable recovery.
Heavy winter rainfall contributed to groundwater replenishment due to reduced evaporation during colder months.
A new EU directive mandates that industries, particularly pharmaceutical and cosmetics sectors, cover 80% of costs for advanced wastewater treatment upgrades by 2027.
The directive aims to address pollutants like microplastics and antibiotic-resistant pathogens, but industries warn of potential price increases and economic impacts.
