Moscow Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Copper plumbing joined with lead solder was standard practice through the mid-1980s — a design choice that federal regulators prohibited in 1986. Moscow's residential inventory, centered around a median build year of 1995, is weighted toward the post-prohibition era. That context is relevant because the primary plumbing risk in older homes comes not from the municipal water supply but from what happens as water moves through lead-jointed pipes inside the structure — an exposure pathway that newer homes mostly avoid.
Most homes in Moscow were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

What You Can Do in Moscow
- 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. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
