No rainwater on Earth is safe for consumption and use as per-, and poly-fluoroalkyl substances (PFAS) readily contaminate the hydrological ecosystem (properties, distribution, and circulation of water), according to a study published in Environmental Science and Technology. This finding is concerning as it adds to research demonstrating chemical pollutants (e.g., pesticides, pharmaceuticals, PFAS, heavy metals, radioactive material, etc.) exceed the “planetary boundary” contamination and needs addressing. The Stockholm Resilience Centre, Stockholm University study, “Planetary Boundaries: Exploring the Safe Operating Space for Humanity,” emphasizes that there are nine “planetary boundaries” related to climate change, biodiversity loss, the nitrogen cycle, the phosphorous cycle, stratospheric ozone depletion, ocean acidification, global freshwater use, changes/intensification of land use, atmospheric aerosol loading, and chemical pollution. When crossing these boundaries, the risk of generating large-scale abrupt or irreversible environmental changes increases. In fact, anthropogenic (human) activities are increasing global contamination levels past safe thresholds.
