Arsenic And Heavy Metal Removal
Removal of Arsenic From Drinking Water
As we’d covered in a prior post, arsenic levels are pretty high in Wisconsin. To sell a home, your well will be tested for arsenic. If it is over 10ppb, you will need to fix your water before closing.
There’s probably a fair question here: If the water won’t be good enough for the next homeowner, is it good enough for you? If I lived on an untested well, I’d invest the $35 and get the test done.
We’ve been getting a lot of these failed well tests and have resolved each. Cedarburg and Mequon have always sat on highly concentrated levels, but we’re seeing failed tests in New Berlin, Wales, Sussex and probably another half-dozen towns I can’t think to name right now.
Here’s an example of a recent successfully closed home. Test results on the home: 22 ppb. Beautiful little baby in the house. So their results were at 220% of the allowable limit.
We installed the Kinetico K5. The full datasheet is here. It eliminates 99.3% of both forms of arsenic.
Results: Complete elimination of arsenic.
Removal of Copper, Lead or Mercury from Drinking Water
There is a not-so-fine line between what is healthy and what is legal in terms of your municipal water supply. Focusing on copper:
Health Limit: 300 ppb
Legal Limit: 1,000 ppb
Not to pick on any one town–well, actually, going alphabetically: Brookfield has extremely high copper levels, averaging over 500 ppb and peaking over that 1,000 mark. You can see a compiled list of old water tests here.
Unlike arsenic, there are alternatives to the Kinetico K5 Reverse Osmosis system here, but we’d eliminate 98.7% of copper or 98.1% of lead.
For municipal water, it is tested at the source. If you’re on Milwaukee water or in a town like Wauwatosa or New Berlin that buys from Milwaukee, your water runs over a network of 2,000 miles of pipe averaging more than 80 years old. Your lead levels aren’t going down on the trip to your home.
