You do not need to turn your kitchen into a laboratory. If you’re on a budget: buy the test strips, then buy distilled water for drinking. If you drink a lot of coffee or tea (like me, three pots a day), get a countertop RO unit. The taste difference is unreal—your coffee will taste like it came from a $500 pour-over setup.
Bob? He now uses a small RO unit just for the fish tank. The koi are thriving, and he’s stopped naming them after his ex-girlfriends. Progress, people. Your kidneys don’t have to work overtime just because your well water is a little extra. Filter it, drink it, and move on with your life.
