Key facts about

Alaska's water supply

With around 740,000 people calling Alaska home, the state relies on roughly 400 community water systems, from large city utilities to small rural networks, to keep water flowing to homes and businesses. Most public water systems in the state draw from groundwater wells, but several of the largest utilities use lakes and creeks, so about half of the people served get surface water. Anchorage takes most of its supply from glacier-fed Eklutna Lake.

Alaskans benefit from regulated water that’s monitored all year round. However, the state also runs into its own challenges that affect the water, such as extreme cold, thawing permafrost in rural areas, and snowmelt and flooding in spring. Hardness varies widely too, from hard water reported in Fairbanks to soft water estimated along much of the Southeast coast. Hard water is safe to drink, but it can leave limescale on fixtures and make soap harder to lather. Many homes also rely on private wells, which aren’t regulated in the same way as public systems, and naturally occurring arsenic has been found in wells in several regions. That’s why understanding your area’s water quality and potential issues is important, as it means you can then decide whether a household water treatment is a good option.

Fact 1: Around 400 community water systems serve Alaska's roughly 740,000 residents, from large city utilities to small rural systems, all regulated by the Alaska Department of Environmental Conservation (DEC).

Fact 2: About 80% of Alaska's public water systems use groundwater, but because several of the largest utilities draw from lakes and creeks, about half of the people served get surface water. [VERIFY: DEC's 2024 report counts all public systems, including schools, workplaces and campgrounds, not only community systems]

Fact 3: Anchorage gets almost 90% of its water from Eklutna Lake, fed by Chugach Mountain snowfields and glaciers. Fairbanks relies on wells in the Tanana Valley aquifer, and Juneau uses a mix of wells and a reservoir.

Fact 4: Alaska has no single hardness profile. Anchorage and the Mat-Su Valley are moderately hard to hard, the Fairbanks utility has reported hard water, and much of coastal Southeast Alaska and Kodiak is estimated to be soft.

Fact 5: Anchorage, Juneau and Fairbanks's main utility each report using chlorine as their disinfectant. Other utilities may differ, so your annual water quality report confirms what your supply uses.

Fact 6: Naturally occurring arsenic has been found in private wells in the Fairbanks area, the Mat-Su Valley, the Kenai Peninsula and Anchorage, and the state recommends testing wells for it in relevant areas.

Fact 7: New showerheads sold in Alaska can use up to 2.5 gallons per minute (GPM), the federal limit. Alaska hasn't set a stricter state limit.

Is my water safe to drink?

In most cases, yes. The EPA sets national drinking water standards, and DEC enforces them for public water systems in Alaska. Every community water supplier must publish an annual Consumer Confidence Report showing where its water comes from, what it tests for and what it found.

Changes in taste, smell or mineral content don’t necessarily mean water is unsafe. Older household plumbing can affect quality, though, particularly where lead pipes or fittings are present.

Private wells aren’t regulated the way public systems are. DEC doesn’t sample, test or regulate private well water, so homeowners are responsible for arranging testing. DEC recommends testing at least once a year for nitrate and coliform bacteria, considering arsenic in areas where it occurs naturally, and using a State of Alaska certified laboratory.

Water quality by city:

  • Anchorage
  • Fairbanks
  • Juneau
  • Wasilla
  • Palmer
  • Sitka
  • Kodiak
  • Petersburg

Some Alaskans still run into water issues at home. Public water is generally safe to drink, but taste, smell and hardness vary from region to region, with harder water reported in Fairbanks and softer water estimated along the Southeast coast. In older buildings, pipes and fittings can affect water quality, particularly where lead is present. In rural areas, freezing temperatures and thawing permafrost can strain small water systems, and if you have a private well, testing it is your responsibility.

Statewide water issues

Naturally occurring arsenic: Arsenic in Alaska groundwater comes mainly from minerals in the rock and soil. It has been found in wells around Fairbanks, the Kenai and Seward areas, the Mat-Su Valley and Anchorage. Levels can change with the seasons or after events such as earthquakes, and arsenic can't be seen, smelled or tasted, so the state's geological survey recommends testing private wells every year.

PFAS: Groundwater near Eielson Air Force Base in Moose Creek, outside North Pole, is contaminated with PFAS, which the Air Force's firefighting foam is believed to have caused. Private wells there could no longer be used, and the city extended its municipal system to affected homes. Statewide, DEC began sampling community and non-transient systems for PFAS in 2024. Initial monitoring runs to April 2027, and the federal limits apply from April 2029. Check your utility's latest results.

Permafrost and rural water systems: Permanently frozen ground makes it harder to install and maintain pipes, wells and storage. In some rural communities, thawing permafrost, erosion and storms have damaged water and sewer lines or cut off water sources. In 2016, the reservoir serving Point Lay drained after ice wedges in the permafrost collapsed. An estimated 3,000 households, about 10,000 people, still lacked running water and sewer service as of 2017. [VERIFY: look for a more recent household count from DEC or ANTHC]

Freezing and flooding: Extreme cold can freeze exposed pipes and interrupt service. Snowmelt and heavy rain can raise river flows and flood private wells, which should be tested before the water is used again.

Private wells: Wells don't benefit from the monitoring that public utilities carry out. DEC recommends annual testing, and extra testing after flooding, a damaged well cap, a septic failure or nearby excavation.

Older plumbing: Lead isn't usually present in water leaving treatment plants, but it can enter from older service lines and fittings inside a property. Anchorage's utility reports no known lead service lines, though it is still inventorying lines of unknown material. Your utility can tell you about your address.

Where Alaska’s water comes from

Lakes and glacial meltwater: Anchorage draws almost 90% of its water from Eklutna Lake, which is fed by snowfields and glaciers in the Chugach Mountains. The rest comes from Ship Creek and from groundwater wells in the Anchorage Bowl. Surface water is treated before it reaches homes, and its quality can shift with snowmelt and runoff.

Groundwater: Wells supply most of Alaska's public systems by number. Fairbanks's main utility, Golden Heart Utilities, pumps from three wells in the aquifer beneath the Tanana Valley. Juneau gets about two-thirds of its water from the Last Chance Basin wellfield and about one-third from Salmon Creek Reservoir. Mineral levels in groundwater depend on local geology. [VERIFY: Golden Heart Utilities source and hardness come from its 2018 report; check the latest report]

Rural community systems: Many small and remote communities rely on local wells, surface water, central watering points or haul systems rather than a piped network. More than 30 rural communities are classed by DEC as unserved, meaning a large share of homes lack piped, well-and-septic or covered haul water.

Private wells: Some homes aren't connected to a public network. Their water quality depends on local groundwater and how well the well is maintained. Contamination isn't always visible, and it can't always be smelled or tasted.

Water across Alaska: areas and their issues

Water quality differs significantly from one part of Alaska to another. These are the areas and issues that come up most often.

  • Anchorage · Eklutna Lake, Ship Creek and well supply, moderately hard water (around 4.9 to 7.6 gpg), chlorine disinfectant
  • Fairbanks · Groundwater from the Tanana Valley aquifer, hard water (around 8.3 gpg in the utility’s 2018 report), arsenic found in some area wells
  • North Pole & Moose Creek · Historic sulfolane and PFAS contamination in groundwater; the city’s municipal water system has been extended to affected homes
  • Wasilla, Palmer & the Mat-Su Valley · Arsenic found in Mat-Su Valley wells; test private wells
  • Juneau · Wells plus Salmon Creek Reservoir; chlorinated; no detectable PFAS in source water, per the utility
  • Kenai Peninsula & Seward · Arsenic found in some wells
  • Rural western and interior Alaska · Thawing permafrost, erosion and freezing temperatures strain small water systems; some homes rely on haul water

Shower flow limits in Alaska

Shower flow is measured in gallons per minute (GPM): how much water leaves the showerhead each minute. Water pressure is a different measure, in pounds per square inch (PSI): the force pushing water through your pipes. A showerhead’s GPM rating sets the most water it can deliver; your home’s pressure decides how forceful that water feels.

Alaska follows the federal limit: new showerheads sold in the US can use no more than 2.5 GPM, measured at 80 PSI. Alaska hasn’t set a stricter limit for showerheads sold in the state.

In 2025, the US Department of Energy changed how the federal limit applies to showers with several nozzles, so multi-head fixtures are no longer capped at 2.5 GPM combined. Single showerheads are still limited to 2.5 GPM.

Many showerheads use less than the legal maximum. Models with the EPA WaterSense label use 2.0 GPM or less. If your shower feels weak, the cause is usually low water pressure in your home, a clogged showerhead or a flow restrictor, rather than the flow limit itself. Your utility can tell you the typical water pressure in your area.

Alaska Water Myth Busters

How a shower filter helps

Alaska's water comes from a mix of glacier-fed lakes, rivers, groundwater and private wells, so general claims about "Alaska water" don't apply to every home. Here's what's actually true.

Myth Glacier-fed water means Alaska's tap water is always soft and pure.

Fact: Meltwater is only one source, and hardness varies widely. Anchorage is moderately hard and Fairbanks's utility has reported hard water, while parts of Southeast Alaska are estimated to be soft. All public supplies are treated and monitored.

Myth A shower filter will soften hard water.

Fact: A shower filter isn't a water softener and doesn't remove calcium or magnesium. Shower filters are designed to reduce other substances, such as chlorine, sediment or certain metals, depending on their filter media.

Myth All Alaska tap water is treated with chlorine.

Fact: Anchorage, Juneau and Fairbanks's main utility report using chlorine, but treatment varies between systems. Your water quality report will confirm what is used in your area.

Myth Arsenic is only a problem in remote areas.

Fact: Arsenic has been found in private wells in and around Fairbanks, Anchorage, the Mat-Su Valley and the Kenai Peninsula. It has no taste or smell, so testing is the only way to know.

Myth The state tests private wells.

Fact: DEC doesn't sample, test or regulate private well water. Owners are responsible for testing, and DEC recommends using a certified laboratory.

Myth A shower filter makes water safe after a flood.

Fact: : Shower filters aren't designed for this. Follow guidance from your utility or public health authorities, and test private wells before using the water again.

Myth Well water that looks and tastes normal is safe.

Fact: Nitrates, arsenic and bacteria can't be seen, smelled or tasted. Regular testing is the only way to know.

The simple shift your skin will thank you for

No plumber, no tools needed; simply unscrew your existing shower head, twist on your Aquabliss filter, and reattach the shower head. The whole set-up process takes under 5 minutes.
Once it's on, there's nothing to think about, your Aquabliss filter works quietly in the background. When it's time for a replacement cartridge (every 3-6 months depending on your water quality), just unscrew, swap, and carry on.
Aquabliss fits any standard ½-inch shower connection — which covers the vast majority of homes in the US. It works with fixed heads, handheld, rain showers, and combo setups.

FAQs

Is Alaska’s water hard or soft?

It depends where you live. Anchorage and the Mat-Su Valley are moderately hard to hard, Fairbanks’s main utility has reported hard water, and parts of Southeast Alaska and Kodiak are estimated to be soft. Check your utility’s report for your supply.

Is Alaska tap water safe to drink?

In most cases, yes. Public water is regulated by DEC under federal Safe Drinking Water Act standards, and community water systems publish an annual water quality report.

Does my water have chlorine or chloramine?

It depends on your utility. Anchorage, Juneau and Fairbanks’s main utility report using chlorine, and others may differ. Your annual water quality report will say which.

Is there arsenic in Alaska water?

Arsenic occurs naturally in some Alaska groundwater and has been found in private wells in several regions. Public systems must meet federal limits. If you have a private well, test it, since arsenic can’t be seen, smelled or tasted.

How often should I test my private well?

DEC recommends testing at least once a year for nitrate and coliform bacteria, and considering arsenic in areas where it occurs naturally. Test more often after flooding, a change in taste, smell or appearance, or a septic failure.

What’s the shower flow rate limit in Alaska?

Alaska follows the federal limit: new showerheads can use no more than 2.5 gallons per minute (GPM), measured at 80 PSI. GPM measures flow, not water pressure. Pressure is measured in PSI and varies from home to home.
