The PF-2/4 is an alumina based sorbent. Interestingly enough, this filtration method results in ABSR's(Arsenic Bearing Solid Residuals), which in this case would be your pf-2 or pf-4 filter once your finished. The U.S. Environmental Protection Agency (EPA), and various other gov't agencies participate in programs to help properly dispose of ABSR's that are the byproduct of municipal water systems removing arsenic from their groundwater source. As a follow-up, I'll need to verify that the PF-2/4 alumina media binds to the arsenic tightly enough so as not to allow for a re-leeching once it hits a landfill.

It's not a dissolved solid like salt, that can't be removed by filters? Is filtering out arsenic (rather than distillation or RO) even possible?
