If your tap water appears milky or cloudy, it is usually an indication of air in the system. This just means that somewhere in your area, we are flushing the system or a new line is being installed. Water mains are flushed by opening fire hydrants and allowing them to flow freely for a short period of time. The flushing cleans out sediment, which accumulates normally in the water mains. Another cause of air in the system is cold weather. Your water is still safe to drink and use. Allowing the water to stand for a minute will help clear it.
