How Old Is Santa Ynez's Housing Stock?
With 67% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Some homes in Santa Ynez predate the 1986 federal restrictions on lead in new pipe and solder, so a tap test is a reasonable step for older homes; median build year: 1973.
Over half of homes in Santa Ynez were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Protecting Children from Lead in Santa Ynez
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

What You Can Do in Santa Ynez

For Nitrate, listed in the water-quality records for Santa Ynez: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it.
