Home Safety Score
Average Home Safety Score for Denmark: D (53/100)
The score combines three factors:
| Factor | What It Measures |
|---|---|
| Water Quality | EPA violations and compliance history |
| Lead Levels | 90th percentile lead concentration vs EPA action level |
| Radon Risk | EPA radon zone classification |
Water Sources
Denmark water systems draw from: Groundwater.
Lead & Copper
- Lead data: not yet available for Denmark
- 0 ZIP codes exceed the EPA lead action level
Radon Risk
Dominant radon zone: Zone 1 (High Risk)
The EPA recommends testing homes in Zone 1 and Zone 2 areas for radon.

Housing & Infrastructure in Denmark
With 66% 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
Viewed through the lens of construction era, Denmark is predominantly an older city — a median build year of 1973 puts most of the residential inventory in the range where pre-1986 plumbing materials were the standard.
Over half of homes in Denmark 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 Denmark Homeowners
Although the Denmark remediation share is moderate, it remains reachable for most homeowners who plan for the expense in advance.
Remediation costs are moderate relative to home values in Denmark. The estimated $2,000–$4,000 range is manageable for most homeowners but still worth budgeting for. Home values are 9% below the Maine average.
Lead Exposure Risk for Children in Denmark
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 66% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Denmark.

Flood & Climate Risk in Denmark
FEMA data shows 100% of Denmark's ZIP codes mapped into designated flood zones, paired with an NFIP record of 2 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Denmark has a moderate flood history with 2 FEMA claims. 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>$3,000</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.

What You Can Do in Denmark
- 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 66% 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.
