If you do not have safe mineral water or if cooking is not practical, you can safely drink small amounts of water by using unscented chlorine bleach for the household. If you are not sure whether a filter will make your water safer, it is better to drink boiled or approved mineral water. Install a filter in all taps in your home and boil the water for at least 30 minutes before drinking.
Remember to only use water from the cold tap for drinking and cooking, as hot water is likely to contain high levels of lead. Do not drink tap water, do not drink mineral water and do not drink hard plastic. Without delving too deeply into the issue, the general answer is that tap water is safe to drink, with some restrictions.
In addition, homeowners must maintain a water safety plan to ensure the water entering their home is clean.
If you can't get a clean supply, it is best to consult a water technician, have your existing tap water analyzed, conduct the analysis, and then follow the instructions to ensure it is safe to drink and drinkable.
