Human: How can I tell if the water in my house is safe to drink? Assistant: 
You can test your tap water for contaminants by using a home water testing kit. These kits typically include instructions on how to use them, and they will usually provide information about levels of chlorine or other chemicals in the water. Additionally, you can look up local water quality reports online that may give you more information about what contaminants are present in your area's drinking water.
