Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Marble Falls'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
Housing age is a practical proxy for plumbing risk because federal standards changed in 1986, when lead solder was banned from new residential construction, and again earlier — before 1970, lead pipes were themselves commonly installed. Marble Falls's median build year of 1995 sits in the range where both pre- and post-1986 homes are well represented. The bar chart above reflects that mixed picture: the distribution captures pockets of older housing alongside more recent development, and those pockets carry real lead risk potential at the individual property level.
Most homes in Marble Falls were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Marble Falls: Remediation Cost in Perspective
Across Marble Falls, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.
Remediation costs in Marble Falls are relatively low compared to home values. The $1,650–$3,900 estimated range is a small fraction of median property value. Home values are 38% above the Texas average.
Protecting Children from Lead in Marble Falls
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.
When older housing represents 37% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Marble Falls address.

Climate-Related Water Risk for Marble Falls
Measured across the NFIP's multi-decade tracking period, Marble Falls shows a moderate flood record — 372 claims and 100% of ZIP codes carrying FEMA flood zone status. For water quality, that combination matters because flood events at this frequency can periodically stress infrastructure: treatment plants, private wells, and distribution systems all face elevated risk during significant flooding.
Marble Falls has a moderate flood history with 372 FEMA claims averaging $39,779 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>$2,600</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.
