Housing Age Profile
Development in Roberts unfolded across multiple decades, and the median build year of 1983 reflects a housing inventory where eras of construction are genuinely mixed — including portions that predate the federal prohibition on lead solder in plumbing.
Most homes in Roberts were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Roberts
Low proportionality — that's the Roberts picture when remediation costs are placed against typical home equity.
Remediation costs in Roberts are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 68% above the Montana average.
Roberts: 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.
Wherever 49% of local housing was built before solder rules changed — as is the case in Roberts — a faucet-level sample closes the gap that aggregate utility data cannot.

Roberts: Flood History & Water Damage Risk
Roberts's flood exposure sits in the moderate range: 5 NFIP claims on record and 100% of ZIP codes within FEMA-designated flood zones. Residents with private wells or older infrastructure have reasonable grounds to factor flood timing into their water quality awareness.
Roberts has a moderate flood history with 5 FEMA claims averaging $5,932 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$2,400</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
