Key Contaminants Detected in Tubac
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Tubac's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Development in Tubac unfolded across multiple decades, and the median build year of 1996 reflects a housing inventory where eras of construction are genuinely mixed — including portions that predate the federal prohibition on lead solder in plumbing.
Most homes in Tubac were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Tubac: Remediation Cost in Perspective
Property equity in Tubac runs well ahead of estimated remediation costs — a cost-to-value ratio that sits in the low tier, meaning documented water and safety issues here are the kind homeowners can plan to address without treating the expense as a significant budget event relative to what their homes are worth.
Remediation costs in Tubac are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 55% above the Arizona average.
Protecting Children from Lead in Tubac
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.
Wherever 36% of local housing was built before solder rules changed — as is the case in Tubac — a faucet-level sample closes the gap that aggregate utility data cannot.

Climate-Related Water Risk for Tubac
Taken together, Tubac's 20 NFIP flood insurance claims and 100% FEMA flood zone coverage place it in the moderate range of exposure. That middle position has specific implications for water quality. The contamination pathways that flooding can open — surface water overwhelming treatment facility intake, floodwaters infiltrating private wells, distribution pressure changes creating backflow — are not constant risks in a moderate-exposure community. But they do become active during significant flood events, and the claim record here indicates enough of those events to make flood timing an occasional factor in local water quality conversations.
Tubac has a moderate flood history with 20 FEMA claims averaging $2,668 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>$1,600</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.

What You Can Do in Tubac

- Check your home's plumbing. With 36% of homes built before 1986, lead solder is a real possibility.
