Your water can become contaminated if connections to your plumbing system are not properly protected.
The City of Two Rivers and Hydro Corp has released a pamphlet that aims to help you protect your home’s drinking water from the hazards of cross-connections and backflow. They suggest you keep the ends of hoses clear of all possible contaminants, ensure that lawn irrigation systems have proper backflow protection, and verify and install a simple hose bibb vacuum breaker on all threaded faucets around your home.
Things you should not do include submerging hoses in buckets, pools, tubs, sinks, or ponds, using spray attachments without a backflow prevention device, and connecting waste pipes from water softeners or other treatment systems directly to the sewer or submerged drain pipe.
