Lead & Copper Rule Results
What Is a Consumer Confidence Report?
Every community water system in the U.S. is required by the EPA to publish an annual Consumer Confidence Report (CCR), also known as a Water Quality Report. It lists all detected contaminants, their levels compared to federal limits (MCLs), and information about where your water comes from.
How to Read Your CCR
- MCL (Maximum Contaminant Level) — the highest level of a contaminant allowed in drinking water
- MCLG (Maximum Contaminant Level Goal) — the level below which there is no known health risk
- Action Level — used for lead and copper; triggers treatment if exceeded at the 90th percentile
- A violation means detected levels exceeded the MCL — your utility must notify you and take corrective action

Termite Risk for 68521
Moderate Termite ZoneRequired for VA/FHA loans in select southern counties only
VA/FHA loan in designated counties will not close without NPMA-33
Termite Damage in the U.S.
- Termites cause an estimated $5 billion in property damage annually in the United States, according to the USDA.
- Standard termite treatment costs $225–$2,500; fumigation for severe infestations: $2,000–$8,000.
- Homeowner insurance typically does not cover termite damage, as it is considered preventable.
What Homeowners Should Know
- Annual termite inspections are recommended in moderate-to-heavy risk zones. Early detection can prevent thousands in repair costs.
- VA and FHA loans require a clear NPMA-33 (Wood Destroying Insect Inspection Report) for closing in most states.
- Warning signs: mud tubes on foundation walls, hollow-sounding wood, discarded wings near windows, and frass (droppings) near baseboards.
- Preventive treatment ($200–$900 per year) is far less expensive than structural damage repair, which averages $3,000 and can exceed $50,000.
- Even in lower-risk zones, subterranean termites can be active. Consider an inspection if purchasing an older home or if you notice warning signs.

Wildfire & Smoke Risk Profile
Wildfire Smoke Safety Tips
- Air purifier with HEPA filter: run in the room where you spend the most time. Close windows and doors during smoke events.
- N95 or KN95 masks: standard cloth and surgical masks do not filter fine particulate matter (PM2.5) from wildfire smoke.
- Seal gaps: use wet towels or tape around doors and windows to reduce smoke infiltration during poor air quality days.
- Monitor AQI: check AirNow.gov daily during fire season. AQI above 100 = unhealthy for sensitive groups; above 150 = unhealthy for everyone.
- Create a clean room: designate one room with the air purifier running, keep it sealed, and limit time outdoors when AQI is elevated.
Protect Your Indoor Air from Wildfire Smoke
A HEPA air purifier can reduce indoor PM2.5 by up to 80% during smoke events. Portable units for a single room start at $80. Whole-home solutions start at $300.

Earthquake & Seismic Risk Profile
Earthquake Preparedness Tips
- Secure heavy furniture: anchor bookshelves, water heaters, and large appliances to wall studs. Unsecured items cause most earthquake injuries.
- Emergency kit: water (1 gallon per person per day for 3 days), non-perishable food, flashlight, batteries, first aid kit, wrench to turn off gas. Keep kits at home and in your car.
- Know how to shut off gas: locate the gas meter shutoff valve and keep a wrench nearby. Gas leaks are a leading cause of post-earthquake fires.
- Drop, Cover, Hold On: during shaking, drop to hands and knees, take cover under a sturdy table, and hold on. Do not stand in doorways or run outside.
- Structural retrofit: homes built before 1980 may need foundation bolting or cripple wall bracing. FEMA's earthquake resources offer guidance on retrofitting.
- USGS ShakeMap: monitor real-time and recent seismic activity at earthquake.usgs.gov.
Build Your Earthquake Preparedness Kit
FEMA recommends every household in a seismic zone maintain a 72-hour emergency kit. Pre-assembled kits start at $40 and include water, food, first aid, and tools.

Mold Risk Assessment for 68521
Low RiskHumidity levels in 68521 remain relatively consistent year-round (summer: 64%, winter: 60%). Mold risk does not spike seasonally, but persistent indoor moisture sources still require attention.
Why Mold Matters
- The CDC and EPA identify mold as a significant indoor health hazard. Common symptoms include respiratory irritation, allergic reactions, and asthma exacerbation.
- Mold begins growing within 24–48 hours on damp surfaces when relative humidity exceeds 60%. Bathrooms, basements, and crawl spaces are most vulnerable.
- Professional mold remediation costs $1,500–$9,000 on average. Homeowner insurance often excludes mold coverage unless caused by a "covered peril."
- Homes built before 1980 typically lack modern vapor barriers and ventilation systems, increasing moisture infiltration risk.
Prevention Recommendations
- Use a dehumidifier to keep indoor humidity below 50%. This is especially important in basements, crawl spaces, and bathrooms in high-humidity areas like 68521.
- Ensure proper ventilation: use exhaust fans in bathrooms and kitchens, and keep attic and crawl space vents unblocked.
- Fix leaks immediately. Even small plumbing leaks can create mold-favorable conditions within 48 hours.
- Monitor indoor humidity with a hygrometer ($10–$20). Target 30–50% year-round.
With 62% average humidity, a dehumidifier is the most effective way to reduce mold risk in 68521. Energy Star-rated units cost $200–$400 and can reduce humidity by 20–30%.

What Are Superfund NPL Sites?
The National Priorities List (NPL) is the EPA's list of the most contaminated sites in the United States. These sites are eligible for federal cleanup funding under CERCLA (the "Superfund" law). Common contaminants include heavy metals, volatile organic compounds (VOCs), pesticides, and industrial solvents that can leach into soil, groundwater, and air.
- Active Cleanup: EPA is investigating or remediating the site — contamination may still be present.
- Construction Complete: Physical cleanup is done, but long-term monitoring continues.
- Deleted: Site meets EPA cleanup standards and has been removed from the NPL.
Know What's in Your Soil
If you live near a Superfund site, a home soil test kit can detect heavy metals, lead, and other contaminants — especially important if you garden, have children, or use well water.

Pollution and Population Health
This section places two independent federal datasets side by side: environmental measurements from the EPA and population-health estimates from the CDC. They describe the same ZIP code but are collected separately, and each one is read on its own terms.
Local pollution measurements
Air, traffic and contaminated-site indicators for this ZIP code, from EPA programs.
Each bar is this ZIP code’s EJScreen national percentile; a higher value means more exposure compared with other U.S. areas.
Between earliest and latest AirData cycles, Lancaster County, NE county-level median AQI shows a 17.1% increase (5 cycles).
EPA AirData = facility-reported industrial emissions, county rollup. Does not measure ambient or breathable air quality at any specific address. EPA AirData methodology
EPA AirData annual AQI summaries 2020-2024
Two independent datasets. Air and soil pollution data (EPA) and health-prevalence data (CDC) are independent datasets shown side by side for context only. ZipCheckup does not establish a causal link between local pollution and any health condition, and these figures do not demonstrate one.
Population-health estimates
CDC PLACES modeled prevalence among adults in this ZIP code, each shown with its 95% confidence interval. The prior-release figure is shown alongside as a reference point only; CDC explicitly cautions that small-area year-to-year differences may reflect model recalibration rather than real change.
Modeled small-area estimates produced from the BRFSS national survey and census demographics (Zhang et al. 2014). Not direct measurements; not for diagnostic or screening use.
Only CDC PLACES measures present in every release since 2020 appear with a prior-release reference; newer measures (added in 2023 and later) are presented without a prior figure.
Food access for this area
How the USDA classifies access to grocery stores and fresh food across the surrounding census tract.
USDA Food Access Research Atlas tract estimates, mapped from census tract to ZIP code. These are modeled population-level figures, not findings about any individual or any specific address.
Pollution–Health Comparison Index
In 68521, the CDC models adult-asthma prevalence at 9.5%, while a statistical model of local pollution and poverty predicts about 10.4% — below the model’s prediction.
Among U.S. ZIP codes, this one sits at percentile 24 for how far observed asthma is above or below the model’s prediction.
The Pollution–Health Comparison Index is a percentile rank showing how this ZIP code’s observed asthma prevalence compares with what a statistical model would predict from local pollution and poverty alone. It describes a statistical association, not a cause-and-effect relationship.
Here, local pollution and the comparison index point in opposite directions — a reminder that many factors, including age, income, smoking, occupation and healthcare access, shape health outcomes, which is why these datasets show association at most, never causation.
Agricultural pesticide use in the surrounding county
USGS estimates how many kilograms of agricultural pesticides are applied each year in this ZIP code’s surrounding county, plus the five most-applied compounds. These are county-level use estimates, not a measurement of any pesticide in the tap water served to this ZIP code.
Top compounds by volume
The five compounds applied in the largest amounts across this county. Where the EPA sets a drinking-water reference limit (MCL) for a compound, that limit is shown for context — it is a regulatory reference, not a finding of any concentration in this ZIP code’s water.

See the full service-disruption breakdown →What this means
- This score blends four public federal datasets — water-pipe decay, bridge condition, gas-pipeline incident history, and a 90-day disruption estimate — into one area-level measure of infrastructure stress.
- It describes the infrastructure around a home, not the condition of the home itself, and it is a modeled estimate rather than an engineering assessment.
- Aging water mains raise the chance of breaks and service interruptions; a plumber can inspect a home's own supply line and shut-off valve.
Methodology: Water-pipe decay is modeled with an exponential-decay bathtub curve from Census ACS housing age, EPA ECHO compliance records, and EPA infrastructure-needs data. Bridge condition is from the FHWA National Bridge Inventory; gas-pipeline incidents from PHMSA; the 90-day disruption estimate from EPA and FEMA data. The stress score is a weighted composite of these four signals.
All figures are modeled estimates from public federal data. They are not engineering assessments, predictions of failure, or a judgment about any specific structure or utility.
HVAC System Health for 68521
Lower electricity rates in Nebraska (11.76¢/kWh) help offset HVAC costs, but an aging system still wastes energy. Modern high-efficiency systems can reduce consumption by 20–40%.
Seasonal HVAC Tips for Nebraska
- Schedule furnace tune-up before first cold snap
- Replace air filter (every 1–3 months)
- Check thermostat calibration
- Insulate exposed ductwork in attic/crawlspace
- Seal drafts around windows and doors
- Check carbon monoxide detectors (gas furnace)
- Schedule bi-annual professional inspection
Common HVAC Issues for 1994-Era Homes
- Aging compressor — most compressors last 12–15 years; may need replacement soon
- Duct leaks — connections loosen over time, wasting 20–30% of conditioned air
- Lower SEER rating — systems from 2000s are typically 10–13 SEER vs. today's 15–20+ SEER
- Thermostat upgrades — older thermostats lack programming features that save 10–15% on energy
Based on housing age, the HVAC system in homes in this area likely uses R-22 (Freon), which was banned from production in 2020. Only reclaimed supply is available at $50–$150 per pound (was $5 before the ban).
- A typical AC recharge uses 2–5 lbs = $100–$750 per service call
- Replacement with a modern R-454B system: $5,000–$12,000
- R-22 supply expected to be fully depleted by 2030
The Department of Energy requires all NEW furnaces manufactured after December 18, 2028 to meet 95% AFUE (condensing furnaces). Current standard is 80% AFUE.
What this means for you:
- 80% AFUE non-condensing furnaces will no longer be available for purchase
- Condensing furnaces require PVC venting (additional $1,500–$2,500 for retrofit)
- If the furnace is approaching end of life, consider replacing before the deadline to potentially save on installation costs
- Your existing furnace can continue operating — this applies only to NEW equipment
HVAC Questions for 68521
How do I know if my HVAC system needs replacement?
Key signs include: the system is over 15 years old, frequent repairs (more than 2 per year), uneven heating/cooling between rooms, rising energy bills despite normal use, and unusual noises or odors. Based on census data, the median home in 68521 was built in 1994, putting the estimated HVAC system age at ~15 years — which is approaching or past the typical 15–17 year lifespan.
What SEER rating should I look for in a new HVAC system?
As of 2023, the federal minimum is SEER2 15 for central AC in the southern U.S. and SEER2 14 in the north. For Nebraska, look for at least SEER 16–18 for good efficiency. Higher SEER ratings (20+) cost more upfront but save more in areas with high electricity rates. ENERGY STAR certified units are a reliable starting point.
How much does HVAC replacement cost in Nebraska?
A full HVAC replacement (furnace + AC) typically ranges from $5,000–$12,000 depending on system size, efficiency rating, and ductwork condition. Heat pump systems range from $4,000–$10,000. Federal tax credits (25C) cover up to 30% of the cost for qualifying heat pumps and high-efficiency systems. Check our rebates page for Nebraska-specific incentives.
What refrigerant does my AC use and why does it matter?
If your AC was installed before 2010, it likely uses R-22, which was banned in 2020 and now costs $50–$150/lb. Systems from 2010–2024 typically use R-410A, which is being phased down (AIM Act 2025). New systems use R-454B or R-32. When your current system needs major repair, the refrigerant type significantly affects whether repair or replacement makes more economic sense.
Should I replace my furnace before the 2028 efficiency deadline?
If the furnace in a home is over 15 years old and the area has a cold/moderate climate, planning ahead is wise. After December 2028, only 95% AFUE condensing furnaces will be available. These require PVC venting — retrofitting an older home for PVC can cost $1,500–$2,500 on top of the furnace price. Replacing before the deadline with a standard 80% AFUE unit may be more cost-effective if the venting isn't PVC-ready.

Appliance Age Estimates for 68521
Median home built in 1994 (~32 years old). Appliance ages estimated from typical replacement cycles.
How Water Quality Affects Appliance Lifespan
Water conditions in Lincoln directly impact how long your appliances last.
Homes built before 1996 have likely gone through 2+ full appliance replacement cycles. If original appliances remain, they are well past expected lifespan.
Appliance Maintenance FAQ
How often should I flush my water heater?
Flush your tank water heater at least once a year to remove sediment buildup. In areas with hard water, every 6 months is recommended. Sediment reduces heating efficiency and accelerates tank corrosion, shortening lifespan by 2–4 years.
When should I replace my dishwasher vs. repair it?
If your dishwasher is over 9 years old and the repair costs more than 50% of a new unit, replacement is generally more cost-effective. Common signs: dishes not getting clean, water pooling after cycles, or rust spots on the interior.
Does a water softener really extend appliance life?
Yes. A water softener can extend water heater lifespan by up to 30% and reduce dishwasher and washing machine maintenance by preventing mineral scale buildup on heating elements, valves, and spray arms. The Battelle Memorial Institute found that softened water kept water heaters at original factory efficiency over a 15-year period.
Estimates based on U.S. Census housing vintage data and manufacturer-average replacement cycles. Actual appliance age depends on renovation history and maintenance.
Electrical Safety for 68521
Median home built in 1994 (~32 years old).
Common Electrical Issues for 1994-Era Homes
- Aging circuit breakers — breakers can weaken over time and fail to trip during overloads, creating fire hazards
- Insufficient circuits — homes from this era may lack dedicated circuits for kitchen, bathroom, and laundry areas
- Missing GFCI/AFCI protection — current code requires GFCI in wet areas and AFCI in bedrooms; older homes often lack both
- Outdated panel capacity — 100–150 amp panels may be insufficient for modern loads (heat pumps, EV charging, home office)
⚠️ Insurance Compliance Alert
32% of homes in 68521 were built before 1986 — the era when Federal Pacific (FPE StabLok), Zinsco, and Challenger electrical panels were commonly installed.
These panels have a documented 60%+ breaker failure rate and are refused by major insurance companies including State Farm, Allstate, and Citizens (FL).
If you receive an insurance non-renewal notice or 4-point inspection failure:
- Typical deadline: 30 days to replace panel
- Replacement cost: $1,500–$4,000
- Failure to replace: insurance cancellation → mortgage default risk
Insurance blacklist: State Farm, Farmers, Allstate, USAA, Mercury, Citizens (FL), Nationwide.
When to Call an Electrician
- Burning smell from outlets or panel
- Frequent breaker trips
- Sparking or discolored outlets
- Buzzing sounds from wiring or panel
- Before buying a home (especially pre-1980)
- After any water damage or flooding
- Before adding major appliances or EV charger
- If your panel is 25+ years old
Electrical Safety Tips
- Never use a fuse with a higher amperage rating than the circuit is designed for
- Label all breakers clearly in your electrical panel
- Keep 3 feet of clearance in front of your electrical panel
- Test GFCI outlets monthly using the built-in test button
- Replace any cracked or warm outlet covers immediately
- Do not daisy-chain power strips or extension cords
Homes built before 1996 should have their electrical panel and GFCI protection reviewed, especially if no upgrades have been made.
Electrical Safety Questions for 68521
How do I know if my electrical panel needs an upgrade?
Key signs include: frequent breaker trips, a panel over 25 years old, fuses instead of circuit breakers, visible rust or corrosion, and a panel rated below 200 amps if you have modern appliances, HVAC, or an EV charger. Based on census data, the median home in 68521 was built in 1994 — homes of this age often have panels that don't meet current electrical demands.
How much does an electrical panel upgrade cost?
A panel upgrade from 100 to 200 amps typically costs $1,500–$4,000 depending on your location and the complexity of the work. If the meter base or service entrance also needs replacement, costs can reach $4,000–$6,000. Rewiring a full home (common in pre-1960 homes) ranges from $8,000–$15,000+ depending on size and accessibility.
Is aluminum wiring dangerous?
Aluminum wiring itself is not inherently dangerous, but connections between aluminum wiring and copper devices (outlets, switches) can overheat due to differential thermal expansion. The Consumer Product Safety Commission (CPSC) found that homes with aluminum wiring are 55 times more likely to have fire-hazard conditions. If your home has aluminum wiring, a qualified electrician can install COPALUM or AlumiConn connectors to make connections safe.
Is my home likely to have a Federal Pacific or Zinsco panel?
These panels were installed primarily between 1960 and 1985. Based on census data, 32% of homes in 68521 were built during this era. If your home was built in this period and the panel has never been replaced, there is a meaningful chance it contains an FPE StabLok or Zinsco panel. Look for the brand name on your breaker panel door.

Remodeling Permit Questions for 68521
What remodeling work requires a permit in Nebraska?
In Nebraska, permits are generally required for any work that alters the structure, electrical wiring, plumbing, or mechanical systems of a home. This includes kitchen and bathroom renovations involving plumbing or electrical changes, wall removal, room additions, window enlargements, re-roofing, and HVAC replacement. Purely cosmetic work — painting, flooring, cabinet refacing without plumbing changes — typically does not require a permit. Always check with your local building department, as municipal requirements may be stricter than state minimums.
What happens if I remodel without a permit in Nebraska?
Working without a required permit in Nebraska can result in Fines up to $500 per offense, stop-work orders. Beyond legal penalties, unpermitted work creates problems when selling: buyers' home inspectors and appraisers flag unpermitted additions, lenders may refuse financing, and title companies may require permits to be obtained retroactively — often at 2–3 times the original permit fee. In serious cases, you may be required to open walls for inspection or demolish non-compliant work.
How much does a remodeling permit cost in Nebraska?
Remodeling permit fees in Nebraska typically range from $50 to $1200, depending on the scope and value of the project. Most jurisdictions calculate fees as a percentage of the project's estimated construction cost (usually 1–2%) or use a flat fee schedule based on project type. Electrical and plumbing sub-permits may be billed separately. Contact your local building department for an exact fee quote before starting work.

Energy Audit Questions for 68521
How much does a home energy audit cost?
A professional home energy audit typically costs $150–$400 depending on the size of your home and the depth of testing. The Inflation Reduction Act provides a $150 tax credit for qualifying audits performed by a certified auditor, effectively covering a significant portion of the audit cost. Some utilities also subsidize audits for their customers — check with Lincoln Electric System for local programs.
What is the difference between an energy audit and a home inspection?
A home inspection (done during a home sale) evaluates structural and safety conditions. An energy audit specifically measures how your home uses energy and identifies efficiency improvements. Energy audits use specialized tools like blower doors, infrared cameras, and duct blasters that are not part of a standard home inspection. The audit produces a prioritized list of upgrades with estimated costs and savings.
How much can I save after an energy audit?
According to the U.S. Department of Energy, the average audit identifies $200–$400/year in savings. Actual savings depend on your home's age, current insulation, HVAC efficiency, and local energy rates. At current rates in Nebraska, the average home spends approximately $1,235/year on electricity — a 15–25% reduction through audit-recommended upgrades could save $185–$309 annually. With homes in 68521 averaging ~32 years old, there is likely significant potential for improvement.
What rebates and tax credits are available for energy upgrades?
The Inflation Reduction Act (IRA) provides two types of incentives: (1) Tax credits up to $3,200/year for heat pumps ($2,000), insulation ($1,600), windows ($600), and the audit itself ($150); and (2) HEEHRA rebates for income-qualifying households — up to $8,000 for heat pumps, $1,600 for insulation, $2,500 for electrical panels, and $840 for heat pump dryers. Solar panels qualify for a separate 30% tax credit through 2032.
Do I need an energy audit before installing solar panels?
An energy audit is not legally required before installing solar, but the DOE strongly recommends it. Reducing your home's energy consumption before adding solar means you need a smaller (cheaper) system to cover your needs. An audit typically identifies 15–30% in energy reductions through insulation, air sealing, and HVAC improvements — which directly reduces the size and cost of a solar installation.
How long does a home energy audit take?
A comprehensive energy audit takes 2–4 hours for a typical single-family home. The auditor will inspect the attic, basement, walls, windows, HVAC system, water heater, and ductwork. Diagnostic tests (blower door, infrared scan) add precision to the findings. You will receive a written report within 1–2 weeks with prioritized recommendations and estimated costs.
