Problem Check 

The Problem-Check analyzes water for the 20 most common nuisance contaminants. It was designed to help people who are experiencing problems with iron (this test package checks both total and dissolved iron and iron bacteria). Additionally, we look at other contaminants that can cause aesthetic issues such as odor, taste, or discoloration.

Tannins are naturally occurring and can cause aesthetic problems such as discoloration, a possible tangy aftertaste, and an earthy or musty odor. The water may be yellowish and can cause staining on laundry and fixtures.

Information Glyphosate

For those who may not recognize the chemical name Glyphosate, it is the most widely used herbicide on the market today, known as Roundup™. I’m sure many of us have a bottle of this on hand to deal with those pesky weeds in our landscaping. This test would solely look for Glyphosate with a detection level of 0.1 mg/L or parts per million.
