Difference Between Arsenic Quick & Arsenic Low Range Quick

Posted by

We recently head from 'JL' who asked, "What us the difference between low range quick test and quick test for well water for arsenic? What do you suggest I use for my well water. I have used the quick test before but do not know the difference."

Good afternoon, JL, and thank you for your inquiry.

Both tests function the in the same manner expect that the low-range quick targets a range of arsenic concentrations much lower than the standard quick test.

Low detect limit for standard Arsenic Quick = .005 ppm or 5 ppb

Low detect limit for standard Low-Range Arsenic Quick = .002 ppm or 2 ppb

Either test kit will let you know if your water sample(s) have greater than the EPA's suggested limit of .01 ppm (10 ppb) dissolved arsenic. Typically folks using the Arsenic Low-Range Quick have an arsenic reduction system installed in their home and want to know how well their arsenic reduction system functions.

So which should you use?  As we said, both will alert you to presence of the EPA's suggested limit of .01 ppm (10 ppb) dissolved arsenic so quite honestly it does not matter if you only want to know if your water meets the current drinking water standard for dissolved arsenic content.
