Aquamation in South Carolina: Legal Status, Costs, and How It Works

South Carolina legalized aquamation on July 1, 2024. If you've been researching water cremation, bio-cremation, or alkaline hydrolysis — and wondering whether it's actually available in the state — the answer is now yes, with some important caveats about where to find providers.

Human composting is a different question. It's still not legal in South Carolina, and if that's what you're looking for, you'll need to arrange out-of-state transport.

What Is Aquamation?

Aquamation (the commercial name for alkaline hydrolysis) is a water-based process that accelerates natural decomposition. The body is placed in a pressurized vessel with water and alkali salts — typically potassium hydroxide — at elevated temperatures. Over several hours, the soft tissue breaks down into its base components: amino acids, salts, and sterile water. What remains is the bones, which are then processed into a fine powder and returned to the family, much like ashes from flame cremation.

The liquid byproduct is sterile and environmentally benign — it's essentially a concentrated version of what happens naturally when a body decomposes in soil. Most facilities process it through standard municipal wastewater systems after the procedure.

South Carolina's Legal Framework

South Carolina's 2024 legislation (Act No. 223, effective July 1, 2024) amended S.C. Code § 32-8-305(9) to define cremation as "the technical process using either alkaline hydrolysis or heat and flame that reduces human remains to components of either liquid and bone, or bone fragments."

This single sentence is important because it means aquamation is now regulated as cremation — the same legal framework applies. The same authorization hierarchy under S.C. Code § 32-8-320, the same 24-hour waiting period, the same documentation requirements, and the same oversight by the South Carolina Board of Funeral Service all govern aquamation facilities in the state.

Providers must also obtain municipal wastewater discharge permits to process the liquid effluent. This is one reason availability is still limited — the infrastructure investment and permitting requirements are significant.

How Aquamation Compares to Flame Cremation

The key practical difference: pacemakers and other implanted devices do not need to be removed before aquamation. Flame cremation chambers can't safely contain the explosive force of a lithium battery from a pacemaker — removal is legally mandated. Aquamation doesn't create that risk.

What Human Composting Is, and Why It's Different

Human composting, officially called natural organic reduction (NOR), is a distinct process. The body is placed in a vessel with wood chips, straw, and other natural materials. Over several weeks, microbial activity transforms the remains into rich compost soil that can be used in gardens or returned to natural land.

Human composting is not legal in South Carolina as of 2026. The state legislature has considered bills to add NOR to the approved list of disposition methods, but none have passed.

If you want human composting, you must arrange for the transport of remains to a state where it's legal — currently Washington, Colorado, Oregon, Vermont, California, New York, and a growing list of others. Interstate transport requires coordination of Burial-Removal-Transit Permits across jurisdictions and typically costs significantly more than in-state disposition.

Who Has Legal Authority to Choose Aquamation

Since aquamation is legally classified as cremation in South Carolina, the same authorization rules apply. The person who has legal authority to authorize disposition is determined by the hierarchy in S.C. Code § 32-8-320:

1. A pre-authorized agent named in a verified written document
2. Surviving spouse
3. Adult children
4. Parents
5. Adult siblings
6. Adult grandchildren
7. Grandparents
8. Court-appointed guardian

If family members disagree about whether to choose aquamation versus conventional burial, the same rules that govern any cremation dispute apply: if two or more people of equal priority are actively in conflict, the facility cannot proceed, and the dispute goes to probate court.

The 24-hour waiting period that applies to flame cremation also applies to aquamation. No disposition can begin within 24 hours of death.

Finding Aquamation Providers in South Carolina

Not every funeral home in South Carolina offers aquamation. The specialized pressurized vessels are expensive to purchase and maintain, and securing wastewater discharge permits requires coordination with local utilities. As of 2026, availability is concentrated in urban markets around Charleston, Columbia, and Greenville — but the landscape is expanding.

How to find a provider:

1. Call funeral homes directly and ask whether they offer alkaline hydrolysis (use that term — "aquamation" is a trade name and not all providers use it)
2. Ask about pricing and whether it's an in-house process or contracted to a third-party cremation facility
3. Verify the funeral home is licensed with the South Carolina Board of Funeral Service through the LLR website
4. Under the FTC Funeral Rule, you can request a price list over the phone — they're legally required to provide one

When you contact a provider, also confirm how the remains will be returned (typically in a temporary container; you'll need to specify if you want a different urn), and ask what the process is if a loved one has implanted devices beyond a pacemaker (some larger metal implants may still need to be addressed).

Planning Ahead for Aquamation

If you want aquamation for yourself and want to ensure it happens regardless of what family members might decide at the time, South Carolina allows you to document this preference in a verified, attested document that designates a specific person as your disposition agent. That person's authority supersedes the standard next-of-kin hierarchy.

You can also note your preferences in a preneed funeral contract through a licensed funeral director, locking in the aquamation option in advance. Under S.C. Code § 32-7-20, funds in a preneed contract are held in trust — and if you establish an irrevocable preneed contract, those funds are excluded from Medicaid asset calculations entirely.

The South Carolina Funeral Laws & Consumer Rights Guide covers the full legal framework for alternative disposition in South Carolina, including the aquamation legislation, cremation authorization procedures, and what the 24-hour waiting period means in practice. It also addresses preneed contract options for families doing advance planning.
