How to tell if water is portable

     When I first started to think on how to tell if water is portable I new something's such as seeing if you saw little particles in your water. ( if you see that you shouldn't drink it.) but I also knew that that want the only way to tell if water was really portable. As I kept reading I found out that sometimes there are very harmful chemicals and minerals that could be in your water. Like lead thats toxic, you don't want to be drinking water with that in it. Its pretty bad if you have lead in because its toxic and enough could kill, and for a parent because you tell your kids to drink water, and if it has toxic things in it you harming your child. So to get your water detoxified you have to have a professional come to your house and change your filter and work on it till its detoxified.
