Shannon Infrastructure Age
With 50% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Because the majority of Shannon's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1984 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Shannon were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Shannon: Lead Risk & Vulnerable Populations
