What's in Ryan's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Ryan Infrastructure Age
With 85% 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
For residents trying to assess tap water risk in Ryan, the median build year of 1962 is the starting context. It signals that a majority of homes were constructed before 1986 — the year federal rules prohibited lead solder in new plumbing — and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in Ryan were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Ryan
At current valuations, Ryan falls in the moderate remediation-share tier — a level where treating this as a budgeted line item rather than an ad-hoc expense is the practical approach.
Remediation costs are moderate relative to home values in Ryan. The estimated $600–$2,300 range is manageable for most homeowners but still worth budgeting for. Home values are 57% below the Oklahoma average.
Ryan: Lead Risk & Vulnerable Populations
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 85% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Ryan.
