How Old Is San Simon's Housing Stock?
With 51% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in San Simon — it's the dominant profile. The median build year of 1984 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in San Simon were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

San Simon: Remediation Cost in Perspective
Throughout San Simon, fixing documented water and safety issues carries an equity weight that moves remediation out of routine planning territory and into structured financial decision-making.
At 2.3% of home value, remediation costs in San Simon represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,500–$4,800. Home values here are 61% below the Arizona average.
Protecting Children from Lead in San Simon
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Older interior plumbing shapes the local picture: 51% of San Simon homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.

Climate-Related Water Risk for San Simon
How does San Simon's flood record connect to local water quality? The NFIP documents 4 claims — enough to signal recurring events — and 100% of ZIP codes carry FEMA flood zone status. That combination places flooding in the category of factors that can periodically affect water infrastructure, even if the area isn't among the highest-exposure communities in the NFIP dataset.
San Simon has a moderate flood history with 4 FEMA claims averaging $21,429 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$2,800</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
