Review on 🏡 Home Water Test Kit: Accurate Lead, Iron, Copper, and Mercury Testing - EPA Standards | Made in USA by David Dortch

I bought a drinking water test kit and a heavy metal test kit. Tried everything in my drinking water at home and was surprised by the mercury test. The result of the mercury test is brown, which is 1 or 2 levels above the maximum limit. Since I received 2 mercury test strips, I tried the last strip and changed the water sample and now it shows yellow, a good indicator, below the limit. With this result I become unsure if the test is accurate or not. I will try again by buying a new one. I will update this review later. Updates: Just bought a new one. The result is puzzling even at the mercury level. I used both tapes. Use the same water source as the sample and get a different color match. Seems like I wasted my money on this.
