When water pipes burst, many people assume that a section of sidewalk would be soaked or something equally trivial will happen. However, research have shown that the situation can be more dangerous depending on which water pipe is leaking.
Contaminants from pipes can enter the water network through a leak, according to a 2015 study from the University of Sheffield. Because the leak causes a drop in water pressure, pollutants can enter the pipes and move further into the system. If this pipe carries drinking water, such toxins could end up in the area's drinking water.
Short Term Risks: Mold growth, rusty pipes, mild flooding
Long Term Risks: Financial damage, asthma, nasal congestion
