Housing & Infrastructure in Magnolia
With 89% 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
Plumbing risk in older housing is defined by two eras: the pre-1970 period when lead pipes were commonly used for service lines, and the 1970-to-1986 period when lead solder remained standard in copper plumbing until the federal ban. Magnolia's median build year of 1955 lands in a range where both eras are heavily represented in the housing stock. That creates an elevated aggregate environment for plumbing-related lead exposure — one that city-level water quality averages don't capture, because the risk sits inside individual properties rather than in the distribution system.
Over half of homes in Magnolia 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 Magnolia Homeowners
Remediation costs in Magnolia represent a moderate share of typical home values — worth budgeting for carefully, though within reach for most homeowners who plan ahead.
Remediation costs are moderate relative to home values in Magnolia. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 55% below the Minnesota average.
Lead Exposure Risk for Children in Magnolia
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 Magnolia have approached or crossed the regulatory action level on multiple occasions. Combined with 89% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
