What is the Emerging Contaminants Grant?
This is the type of treatment that exchanges a chloride ion for a PFAS molecule.
What is Anion Exchange?
This is what the acronym PFAS stands for.
What is Perfluoroalkyl and Polyfluoroalkyl Substances?
These are the potential health impacts from PFAS exposure.
What are Thyroid disease, birth defects, high cholesterol, metabolic disease, obesity, reduced response to vaccines, kidney cancer, liver disease, impacts to the endocrine system, hormone imbalances ect.?

What are the Rule Trigger Levels?
These are the counties in Colorado with the highest levels of PFAS.
What are Broomfield and Denver counties?
These are non-treatment Alternatives.
What are: Abandon high contaminated source(s), Reconstruct/re-engineer existing wells, Drill new wells, Change pumping rate, Change pump intake location and/or diameter, Blending with uncontaminated sources?
This is the measure of how strongly an atom pulls electrons towards itself when bonded to another atom. Atoms with higher electronegativity tend to attract electrons more strongly, while those with lower electronegativity attract electrons less strongly. What are endocrine disrupters?
What is Electronegativity?
This is the biggest PFAS exposure route (~20%)
What is drinking water?
These are the Initial Monitoring Requirements.
What are Four samples taken within 12 months for surface water systems or systems serving more than 10,000. Two Semi Annual Samples taken within 12 months for groundwater systems serving less than 10,000. Or use of recent, existing PFAS drinking water occurrence data?
