You might wonder if boiling water results in perfectly clean H2O. When communities post a boil water notice, it's simply to make sure any harmful bacteria in the water are eradicated. Boiling water gets those bacteria levels close to zero, but other contaminants, like trace pharmaceutical drugs, pesticide residue and heavy metals, are not removed through boiling and can still linger in your water. If you want truly clean water, you need serious water filtration systems ranging from reverse osmosis to commercial grade filtration that can reliably remove all contaminants.
