If you are asking “Is aquamation legal in Iowa?”, the short answer is: No, human aquamation is not currently legal within Iowa.
Aquamation, scientifically known as alkaline hydrolysis or water cremation, is not defined or recognized under Iowa state statutes regarding human mortuary care and final disposition. Because Iowa state regulations strictly define human cremation as a high-heat, flame-based process, funeral directors in the Hawkeye State cannot legally perform human water cremation within state borders at this time.
However, for eco-conscious families across Des Moines, Cedar Rapids, Davenport, Sioux City, and Iowa City seeking green aftercare, options exist through pet aftercare providers or by arranging out-of-state human water cremation services in nearby states where it is legalized (such as Minnesota, Illinois, Kansas, or Missouri).
This 2026 guide explains Iowa’s legal framework, how aquamation works, out-of-state options, and essential tips for selecting an urn for bone ash remains.
Iowa Aquamation Laws at a Glance
-
Human Remains Legal Status: Not legal for human disposition in-state. No statutory framework currently exists under Iowa funeral laws.
-
Pet Remains Legal Status: Legal and widely available through specialized pet aftercare facilities and veterinary partners statewide.
-
Regulatory Body: Iowa Board of Mortuary Science (under the Iowa Department of Health and Human Services).
-
Workarounds for Human Remains: Families dedicated to water cremation can work with an Iowa funeral home to transport their loved one to an authorized facility in an adjacent state where human aquamation is legal.
-
Final Returned Remains: Pure, pale white bone powder (if processed in an authorized state).
What Is Aquamation (Water Cremation)?
Aquamation also called green cremation, bio-cremation, liquid cremation, or flameless cremation is a gentle, water-based disposition method.
Instead of using direct high heat and fossil fuels to reduce human remains, aquamation uses a solution of 95% warm water and 5% alkali (potassium hydroxide). Over a 6- to 12-hour cycle inside a sealed stainless steel vessel, warm liquid flow and natural alkalinity accelerate the body's natural breakdown process.
At the end of the process, only soft, mineral bone fragments remain. These fragments are dried and processed into a fine white powder that can be safely kept at home, buried, or scattered.
Aquamation vs. Traditional Flame Cremation: Key Differences
| Feature | Aquamation (Water Cremation) | Traditional Flame Cremation |
| Primary Method | 95% Water & 5% Alkali Solution | Direct High Heat / Open Flame |
| Energy Consumption | Uses ~90% less energy | High fossil fuel consumption (natural gas/propane) |
| Emissions | Zero direct greenhouse gas stack emissions | Direct carbon dioxide and thermal emissions |
| Returned Remains | Fine, pale white powder | Coarser, gray bone ash |
| Ash Volume | ~20% to 30% greater returned volume | Standard baseline volume |
How Much Does Aquamation Cost?
Because human aquamation cannot be performed inside Iowa, costs depend on whether you are using local pet services or transporting human remains out of state:
-
Pet Aquamation in Iowa: $150 – $450 (varies by pet weight and local provider)
-
Out-of-State Human Aquamation: $2,500 – $4,500+ (includes transportation, out-of-state provider fees, and shipping of returned remains)
-
Standard Flame Cremation in Iowa: $1,200 – $3,000 (widely available statewide)
Choosing an Urn for Returned Ashes
Whether choosing local flame cremation or transporting ashes back from an out-of-state aquamation provider, selecting the right urn capacity is critical. Because aquamation preserves slightly more bone material than high-heat incineration, the returned remains typically occupy 20% to 30% more space than standard flame cremation ashes.
When shopping for an adult memorial vessel, keep internal capacity top of mind:
-
Adult Full-Sized Urns: For water cremation remains, select urns with a volume capacity of 220 to 250+ cubic inches (rather than standard 200 cu. in.) to ensure all ashes fit comfortably.
-
Keepsake Urns: Small mini urns designed to hold a small portion of ashes, allowing multiple family members to share a token memory.
-
Cremation Jewelry: Keepsake pendants and bracelets engineered with tiny inner chambers to carry a small piece of your loved one near your heart.
-
Water-Soluble & Scattering Urns: Designed for natural ash-scattering ceremonies in rivers, private land, or designated outdoor spaces.
Frequently Asked Questions (FAQ)
Will human aquamation become legal in Iowa?
