Clean Water is Essential The earth's water supply we rely upon for daily tasks including consumption, has a number of exposures to contaminants that may require analysis to determine the safety for further use. Some of the risks that water may be exposed to include Coliform and E. Coli, Lead, Legionella, Nanoparticles, Per- and Polyfluoroalkyl substances (PFAS) "forever chemicals", fungal spores, Radon, Petroleum-based particles, and it has become our responsibility to sample and identify the concentrations of these contaminants in our water sources before consumption. "Research has raised concerns about the potential health effects of PFAS exposure. Some studies suggest that high levels of PFAS in the body may be linked to various health issues, including: Hormonal disruptions Increased cholesterol levels Immune system effects Certain cancers** PFAS are persistent in the environment, meaning they do not break down easily and can accumulate in the soil, water, and living organisms. This persistence has led to widespread contamination, with detectable levels of PFAS found in drinking water, fish, and even human blood samples across the globe.
