Housing Age Profile
The character of Grafton's housing stock is one of deep historical layering - a median build year of 1970 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 Grafton 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 Grafton Homeowners
The household financial picture for Grafton homeowners is proportionally favorable - addressing documented issues claims a small slice of equity, and the cost-to-value ratio puts this area well within the manageable tier.

Lead Exposure Risk for Children in Grafton
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 Grafton have approached or crossed the regulatory action level on multiple occasions. Combined with 63% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
