Cross connections between water supplies and sources of contamination represent one of the most significant threats to public health in the water supply industry. A cross connection is a physical connection between the drinking water system and any other piping system containing a non-potable substance. A backflow can occur when a substance flows back into the public water system as water pressure fluctuates.  This could be as a result of a water main break or hydrant usage.
