Top Contaminants in Grayson Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Grayson
With 53% 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.

Housing Age Profile
The character of Grayson's housing stock is one of deep historical layering — a median build year of 1986 signals a city built largely before the plumbing era changes of 1986 and 1970. Lead-soldered copper joints and, in the oldest properties, lead service lines are commonly present in this inventory. That context shapes what individual water testing may reveal, particularly in neighborhoods where the oldest housing is concentrated.
Over half of homes in Grayson were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Grayson Homeowners
How does remediation fit within the broader financial picture for Grayson homeowners? The equity share is moderate — large enough that treating it as a real planning consideration makes sense, and manageable enough that most homeowners have a clear path to addressing documented water and safety issues when they approach the commitment with deliberate advance budgeting rather than as an unplanned expense.
Remediation costs are moderate relative to home values in Grayson. The estimated $1,500–$4,900 range is manageable for most homeowners but still worth budgeting for. Home values are 5% below the Kentucky average.
Lead Exposure Risk for Children in Grayson
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Grayson have approached or crossed the regulatory action level on multiple occasions. Combined with 53% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

Flood & Climate Risk in Grayson
100% of ZIP codes in Grayson are mapped into FEMA-designated flood zones, and the NFIP records 128 claims reflecting a multi-event flood history. That combination places local flood exposure in the range where water-quality implications deserve at least periodic attention.
Grayson has a moderate flood history with 128 FEMA claims averaging $17,596 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>$2,800</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.
