@varifytest: My TDS meter read 1327 ppm at this Yellowstone geyser! The high reading comes from dissolved minerals and solids picked up as the water travels through volcanic rock. For comparison, the EPA recommends under 500 ppm for drinking water. Where should I test next? #TDSMeter #WaterTesting #Yellowstone #ScienceFacts #WaterQuality #varify

Those waters are very acidic so they are going to have a very high TDS reading.

What if we actually need a higher number. The animals drink from it. Just a thought. Heck they put fluoride in our water
