Is Alkaline Hydrolysis in Arizona Legal?

Alkaline hydrolysis is legal across the state. Lawmakers authorized it on May 27, 2022, under House Bill 2024. The bill set licensing rules for the facilities and operators that perform it.

State law defines alkaline hydrolysis as a water-based process that uses alkaline chemicals, heat, agitation and pressure to reduce human remains to their essential elements. Oversight sits with the Arizona Department of Health Services, which absorbed funeral licensing duties from the former state board in 2023.

Here's what the law requires:

• Facilities and operators need a state license before offering the service
• Facilities must meet local building, zoning, wastewater and environmental standards
• The county medical examiner must review and approve the process, the same review used for flame cremation
• Unembalmed remains awaiting the process must be kept in a climate-controlled holding area at or below 38 degrees Fahrenheit inside the licensed facility

What Is Alkaline Hydrolysis?

Alkaline hydrolysis is a water-based alternative to flame cremation. People also call it water cremation, aquamation or green cremation. Families still receive cremated remains to keep, scatter or bury, much like they would after flame cremation.

Many families look into it because it's viewed as a gentler, more environmentally friendly option. According to the Cremation Association of North America, the process uses meaningfully less fuel and has a lower overall carbon footprint than flame cremation.

How the Process Works

The individual is placed in a sealed vessel filled with a warm solution that's about 95% water and 5% alkali. Gentle heat and fluid flow then speed up the natural breakdown of soft tissue over several hours. 

What's left behind is bone material, which is dried and processed into a fine, powdery form. A few things set the result apart from flame cremation:

• The remains tend to look lighter in color and finer in texture
• Lower temperatures make it easier to separate implants like pacemakers
• Families can still keep, scatter or bury the remains in all the usual ways

Who Can Authorize Alkaline Hydrolysis in Arizona?

Arizona uses the same authorization rules for water cremation that it uses for flame cremation. A legally authorized person, called the authorizing agent, must sign a consent form before the process can move forward, as set out in state law governing consent.

The law points to a clear priority order for who that person is:

• The surviving spouse, unless legally separated or a divorce petition was pending at the time of death
• The agent named in the decedent's health care power of attorney or durable power of attorney, if that document grants authority over the disposition of remains
• The adult children
• A parent
• An adult sibling

If the first person in line can't be reached or doesn't act within 15 days of initial contact, the right to authorize passes to the next person on the list. The county medical examiner must also review the death certificate before the process can proceed.

Is Water Cremation Available in Arizona Right Now?

This is where the law and real life can differ. Alkaline hydrolysis is legal across the state, but in-state availability might be limited. That gap is common with newer disposition methods.

Even where a state allows the practice, few facilities have installed the specialized equipment, so legal doesn't always mean locally available. Families who want it sometimes work with a provider that arranges transport to a licensed facility in a neighboring state.

Water Cremation vs Flame Cremation: Cost and Differences

For most families, the decision comes down to cost, availability and personal values. Flame cremation is faster, easier to arrange and usually less expensive. Water cremation tends to appeal to families who want a gentler, lower-carbon option, but it usually costs more, partly because the equipment is a large investment for providers.
