Opening & Testing 60 Year Old Can of Water from a Fallout Shelter! I got a new electronic water safety- purity tester to try out. It’s testing the TDS (Total Dissolved Solids) in PPM (parts per million). Basically the total amount of organic and inorganic substances dissolved in water, such as minerals, salts, and metals. According to this meter the water is in the warning area of 151-300 PPM “Poor Drinking Water- Not Recommended” ☢️ #fallout #cannedwater #emergencywater #falloutfood #survivalfo
