Key Contaminants Detected in Gypsum

How Old Is Gypsum'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
Copper plumbing joined with lead solder was standard practice through the mid-1980s — a design choice that federal regulators prohibited in 1986. Gypsum's residential inventory, centered around a median build year of 1992, is weighted toward the post-prohibition era. That context is relevant because the primary plumbing risk in older homes comes not from the municipal water supply but from what happens as water moves through lead-jointed pipes inside the structure — an exposure pathway that newer homes mostly avoid.
Most homes in Gypsum were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Gypsum: Remediation Cost in Perspective
Given current Gypsum valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Gypsum are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 21% above the Colorado average.
Protecting Children from Lead in Gypsum
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.
Confirming what flows from a specific faucet still requires a one-home draw, even where Gypsum averages stay clean and the pre-rule housing share holds at 28%.

Climate-Related Water Risk for Gypsum
5 FEMA flood insurance claims are on file for Gypsum, and 100% of local ZIP codes fall within federally designated flood zones — enough to put flood exposure on the planning radar, though short of the concentrated-risk threshold where treatment-system vulnerability becomes a primary consideration.
Gypsum has a moderate flood history with 5 FEMA claims averaging $795 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.
