Review on 💧 Watersafe WS425W: Comprehensive Well Water Testing for a Safer, Purer Supply by Elder Unogu

I liked the test suite - it answered my security question. It was easy and all tests except the bacteria test took just over an hour. After 48 hours for the bacteria test, I made a control sample for it by adding bacteria from yogurt and mouse poop to test for a false negative. I am pleased to report that my water tested negative at 48 hours, but my retest at 49 hours with a known bacterial control was positive. Make sure you store the sample within the required temperature range. I used a lightbulb and a meat thermometer. A good product.
