How Old Is Crook's Housing Stock?
With 86% 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
Reading the housing age data for Crook — median build year 1956 — the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints — a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Crook were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Crook: Remediation Cost in Perspective
In Crook, the equity share of documented remediation is meaningful enough to move the household financial perspective from routine maintenance into deliberate budgeting territory — the cost-to-value ratio is moderate, and most homeowners benefit from mapping the full scope against available budgets before committing.
Remediation costs are moderate relative to home values in Crook. The estimated $1,600–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 49% below the Colorado average.
Protecting Children from Lead in Crook
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 86% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Crook.

Climate-Related Water Risk for Crook
Flood exposure in Crook is meaningful by NFIP measures — 7 claims on record and 100% of ZIP codes carrying FEMA flood zone designations. That level of activity makes flood history a relevant factor when evaluating local water quality over time.
Crook has a moderate flood history with 7 FEMA claims averaging $5,550 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>$2,400</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.

- Check your home's plumbing. With 86% of homes built before 1986, lead solder is a real possibility.
