While the Covid-19 pandemic brought the importance of indoor air quality (IAQ) and its impact on human health and safety to the forefront of the public health conversation, the topic isn’t a new one. Nearly 40 years ago, a report by the World Health Organization suggested that up to 30% of buildings worldwide were the subject of excessive IAQ-related complaints, including cough, dizziness, chest tightness and muscle aches.

Our wastewater systems are very efficient at removing pathogens, but not environmental pollutants. Neither do most of them have the right equipment to destroy many pharmaceuticals that come out of us and flow into the seas.

Local officials contend that years of contamination miles upstream sent toxic perfluoroalkyl and polyfluoroalkyl substances, known as PFAS, into Rome’s water supply, rendering it potentially dangerous for the city’s roughly 37,000 residents. A water source switch from the Oostanaula and added treatment have reduced the traces of the chemicals running through residents’ taps, but they have not eliminated PFAS from the community’s water supply.

Researchers say global levels of man-made "forever chemicals" have made rainwater unsafe to drink around the world — even in the most remote areas. The study argues that guideline values – amounts considered acceptable – for per- and polyfluoroalkyl substances (PFAS) in drinking water, surface water and soil have fallen "dramatically" over the last 20 years "due to new insights into their toxicity."

PFAS “forever chemicals” are per- and polyfluoroalkyl substances used as stain-resistant, water-resistant, & oil-resistant chemicals in commerce. They have been used for decades inside consumer products, manufacturing, and building materials. There are over 12,000 different chemicals in the PFAS chemical class (including PFOA & PTFE), and because there are so many of them, they are incredibly hard to identify and test for. In fact, it’s only really possible to identify about 100 or so in a really good commercial laboratory. More:

The controversial class of highly fluorinated chemicals known as per- and polyfluoroalkyl substances (PFAS), which are persistent and potentially toxic, has essentially become a new part of the Earth’s ecosystem. There are estimated to be around 8000 different types of PFAS out there – found in the atmosphere, rain, surface water, groundwater and even people – but technological developments now offer to break this cycle.
