Housing & Infrastructure in Holland
With 43% 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 residential housing tracks directly to construction era: pre-1986 homes may have lead-soldered copper joints; pre-1970 homes may have lead pipes outright. Holland's median build year of 1998 places the city in a moderate risk zone where neither era dominates the housing inventory. Understanding which side of the 1986 threshold a specific property falls on — and whether it predates 1970 — is the most actionable starting point for a homeowner trying to assess their own tap water exposure.
Most homes in Holland were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Holland Homeowners
What does remediation cost in financial context for Holland homeowners? Proportionally very little — the equity share here is low, and addressing documented issues is a manageable planning question rather than a material financial burden.
Remediation costs in Holland are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 34% above the Ohio average.
Lead Exposure Risk for Children in Holland
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 43% pre-rule share in Holland keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Flood & Climate Risk in Holland
Over the multi-decade window covered by the National Flood Insurance Program, Holland has accumulated 16 claims — a total that suggests more than isolated flood exposure. With 100% of ZIP codes in designated flood zones, the water-quality implications of flooding move from hypothetical to periodically relevant: treatment intake can be compromised, wells can be infiltrated, and distribution backflow can occur.
Holland has a moderate flood history with 16 FEMA claims averaging $5,212 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>$1,600</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 Holland
- 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 43% of homes built before 1986, lead solder is a real possibility.
