Perth Infrastructure Age
With 56% 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
Because the majority of Perth's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1972 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Perth 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 Perth
At current valuations, Perth sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Perth are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 6% below the North Dakota average.
Perth: 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.
Routinely in Perth, where 56% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.

What You Can Do in Perth
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. With 56% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
