If you are asking “Is aquamation legal in Maryland?”, the direct answer is: Yes, human aquamation is legal in Maryland.
Aquamation, scientifically known as alkaline hydrolysis or water cremation, was officially legalized for human remains in Maryland following the passage of the Green Death Care Options Act. As families across the Old Line State seek gentle, environmentally conscious alternatives to flame cremation, water cremation availability is steadily expanding throughout the Baltimore metro area, Washington D.C. suburbs, and Central Maryland.
This 2026 guide explains Maryland’s aquamation laws, environmental benefits, average costs, and key tips for selecting an urn for bone ash remains.

What Is Aquamation (Water Cremation)?
Aquamation, also called green cremation, bio-cremation, liquid cremation, or flameless cremation is a water-based final disposition method.
Instead of using direct open flames and fossil fuels to reduce human remains, aquamation uses a gentle solution of 95% warm water and 5% alkali solution (potassium hydroxide). Over a 6- to 12-hour cycle, warm liquid flow and alkalinity accelerate the body's natural breakdown. 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 kept in a home urn, buried, or scattered.
Aquamation vs. Traditional Cremation: Key Differences
| Feature | Aquamation (Water Cremation) | Traditional Flame Cremation |
| Primary Method | 95% Water & 5% Potassium Hydroxide | 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 in Maryland?
In Maryland, aquamation pricing varies depending on regional provider infrastructure and service packages:
-
Direct Human Aquamation: $1,800 – $3,200
-
Full-Service Aquamation (with Memorial Services): $3,500 – $5,500
-
Pet Aquamation: $150 – $400 (varies by pet weight)
Direct aquamation is generally comparable in cost to traditional flame cremation while offering a significantly lower carbon footprint.
Choosing an Urn for Aquamation Remains
Because aquamation preserves more bone material than high-heat incineration, the returned remains typically occupy 20% to 30% more space than flame cremation ashes.
When shopping for an adult memorial vessel, keeping internal capacity top of mind is crucial:
-
Adult Full-Sized Urns: Look for urns with a volume capacity of 220 to 250+ cubic inches to comfortably accommodate aquamated ashes.
-
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 ocean, river, or bay landscapes across Maryland (such as the Chesapeake Bay).
Frequently Asked Questions (FAQ)
Is aquamation eco-friendly?
Yes. Water cremation produces zero direct air emissions, uses roughly 10% of the energy of flame cremation, and returns safe, pathogen-free water to municipal treatment systems.
Can I keep aquamation ashes at home in Maryland?
Yes. In Maryland, cremated remains (whether from flame or water cremation) are considered personal property. Families may keep them at home in a secure urn, place them in a columbarium, bury them, or scatter them on private property with landowner permission.
What size urn do I need for water cremation ashes?
A standard cremation urn typically holds 200 cubic inches. For aquamation remains, selecting an urn rated for 220+ cubic inches ensures all returned ashes fit comfortably.
