We bought a house that has a system for water filtering in it and we think the earlier owners were kinda’ nasty and probably did not change the stuff in the system. Ever. And it looks like it’s been here a while. Do you know where we can get new filter stuff for out filter?

First of all, yes we know where you can get replacement water filter media, but we have no idea if they carry the right type of filter media for your filter. You will have to determine what type of filter you have (i.e water softener, iron/manganese removal system, fluoride removal system, arsenic removal system, general water filter, etc.) and what type of filter media it contains.

A quick look at the arsenic map on Arsenic-Test-Kit.Com will show you that arsenic can appear in groundwater all across the Continental United States and in some areas naturally occurring arsenic levels in ground water greatly exceed the 10 ppb (parts per billion) limit set forth by the USEPA several years ago.

Want to know if your drinking or well water contains dissolved arsenic in concentrations greater then recommended by the USEPA? At-home test kits such as the Arsenic Quick Test Kits for Drinking Water work well as a field screening tool, but the final word ought to come from a certified water testing lab such as National Testing Labs… or you can find lists of certified water testing labs in your state here.

As more and more people become aware of the fact that levels of arsenic in well water can fluctuate with the changing of seasons, after periods of heavy rain and in periods of drought, the demand for arsenic removal systems for residential and commercial use continues to rise.

One of the most common methods of arsenic removal requires the use of a specific type of water filter media, an example of which is a nano-particle based selective iron oxide resin media designed to remove arsenic (arsenate and arsenite) from water.

A quality arsenic removal resin of that nature will have passed all testing and quality requirements outlined in the NSF/ANSI 61 standard.
