If you run an office, clinic or studio in Long Beach, the tap is probably your first water cooler. Whether it is good enough depends on which part of the city you are in and how old your building’s plumbing is. This guide uses the city’s own 2025 water quality report to show what is in the water, then covers when a filtered dispenser makes sense and what an office water cooler cost per month looks like on our plans.
This is a workplace guide, not a household one. We rent water dispensers to businesses only, so we write for office managers and owners. We will go through the numbers in the city’s report, explain the terms, and say plainly where a filter helps and where it does not.
You will leave knowing which water zone your building is probably in, what the report does and does not tell you, and what to ask a provider before you rent a dispenser. Nothing here replaces a lab test of your own taps, which we recommend if you have a concern.
What is in a Long Beach tap, and why offices care
Your tap is the cheapest water you have, and for many buildings it is perfectly good. The reasons to filter are mostly taste, scale in equipment and whatever the pipes inside your own building add. Long Beach also has two kinds of tap water depending on where you sit in the city, and that changes the answer.
Most public talk about water is about drought and conservation. Purity gets less attention. A utility can meet every legal limit and the water can still taste of disinfectant, so legal and pleasant are different questions. Both matter for an office with a kitchen and a team that drinks from it all day.
You should be able to read the numbers yourself, and you do not need a chemistry degree. The rest of this guide translates the city’s 2025 report into plain terms for people who run workplaces.
Why the quality of your building’s water matters at work
Hard water leaves scale on kettles, coffee machines, ice makers and dishwashers. That means more descaling and shorter equipment life. How much depends on your zone, and the report gives a hardness figure for each one, which we cover below.
Taste is the other side. Chloramine, the disinfectant Long Beach uses, gives some people a faint chemical smell. Staff who dislike the taste buy bottled water or bring their own jugs, and then you are back to storage and lifting.
Why Long Beach needs its own guide for workplaces
Generic Southern California advice misses the local detail. Long Beach blends its own groundwater with imported water, and the mix differs by zone. A building in one part of the city may get much softer water than a building in another.
- Older buildings: pipes inside the building can add taste and metals.
- Which zone you are in: the blended zone and the MWD zone have very different hardness.
- Your own taps: the city tests the system, not the faucet in your suite.
Focusing on Long Beach lets us use the city’s actual numbers instead of guesses. None of this is meant to frighten anyone. The report says the water meets every standard, and we will say so too.
Where Long Beach water comes from and how it is treated
To understand the water, start with the source. The Long Beach Utilities Department supplies the city, and in 2025 its own wells supplied most of it. The rest was bought from a regional wholesaler.
According to the 2025 Consumer Confidence Report, published July 1, 2026, 71 percent of Long Beach’s water came from local groundwater in 2025. It is pumped from Central Basin aquifers, which are managed with the Water Replenishment District. That was up from 60 percent the year before.
The other 29 percent was imported surface water bought from the Metropolitan Water District of Southern California. The two supplies are blended at the city’s Groundwater Treatment Plant before they go to most of the service area. Some areas get imported water directly.
The two supplies behind the blend
Local groundwater: the wells draw from aquifers recharged by rain and snowmelt flowing down the San Gabriel River and through Whittier Narrows. Groundwater picks up minerals on the way, which shows up as hardness.
Imported water: the Metropolitan Water District brings it in by two routes, the Colorado River Aqueduct and the State Water Project, which carries water from the Sacramento-San Joaquin Delta. In the 2025 report, the areas that get this water directly have much harder tap water than the blended zone.
Two zones, two kinds of tap water
The report splits the city into a blended zone and an MWD zone. In 2025 the average hardness was 76 ppm in the blended zone and 220 ppm in the MWD zone. If you do not know which one your building is in, call the utility on (562) 570-2479 and ask.
How the water is treated before it reaches you
Groundwater is treated at the city’s Groundwater Treatment Plant, where it goes through sedimentation basins and filtration. The report lists chloramine as the disinfectant added during treatment, and that is what keeps the water safe on its trip through the pipes.
After treatment, the water moves through the network of pipes under the streets, and then through the service line and plumbing of your building. That last part is not the utility’s, and it is where lead and copper can enter from old fixtures.

What the 2025 report found in Long Beach tap water
No water is pure H2O. It dissolves what it touches, so every tap carries minerals, a disinfectant and traces of other things. The question is how much of each, and whether it affects health or only taste.
The word contaminant sounds alarming, but it means anything in the water other than water. Calcium is a contaminant by that definition, and harmless to drink. Arsenic is a different matter at high levels, which is why it has a legal limit.
In 2025 the utility ran more than 63,500 tests, and the report says every contaminant was below its maximum allowed level. That is a good result. It is also the legal bar, and a legal pass says nothing about taste.
What the report lists for Long Beach, in plain terms
Hardness minerals: calcium and magnesium. The blended zone averaged 76 ppm and the MWD zone 220 ppm in 2025. Safe to drink, and the main cause of scale on equipment.
Chloramine is the disinfectant. The highest running annual average across the system was 2.15 ppm in 2025, under the 4.0 ppm limit. It is needed for public safety, and some people notice a faint chemical smell or taste because of it.
Disinfection byproducts form when the disinfectant reacts with organic matter. The city measured total trihalomethanes (TTHM) at 28 to 48 ppb in 2025, against a legal limit of 80 ppb.
Long Beach numbers from the 2025 report
The table uses the Long Beach Utilities Department 2025 Consumer Confidence Report (published July 1, 2026). The levels are averages or ranges for the system. The last column is the health goal or legal limit.
| Contaminant | Potential Source | 2025 level in Long Beach | Goal or limit |
|---|---|---|---|
| Arsenic | Erosion of natural deposits, runoff, industrial processes | 0.6 to 1.3 ppb on average, by zone | 0.004 ppb |
| Chloramines | Disinfectant added during treatment | 0.33 to 2.84 ppm | Limit 4.0 ppm |
| Hardness | Natural minerals in the water | 76 ppm (blended zone), 220 ppm (MWD zone) | No health goal |
| TTHMs | Byproduct of chlorination | 28 to 48 ppb | Limit 80 ppb |
How to read your annual Consumer Confidence Report, step by step
Every year by July 1 the utility publishes its Consumer Confidence Report, and the 2025 edition came out on July 1, 2026. It is full of tables and abbreviations, and many people never open it. Ten minutes with it tells you more than most sales pages do.
The report is built to show compliance, so it lists averages and ranges rather than every individual day. A high reading on one day can sit inside a safe average. Read the range column as well as the average.
Skip to the data tables. Look at the average, the maximum and the range for the zone your building is in, and compare each with the legal limit. A reading far below the limit needs no action; one close to the limit is worth a call to the utility.
Reading the report in three passes
Find the definitions: MCL is the legal limit, and PHG or MCLG is the health goal. The distance between the two tells you how much room there is.
Check the detects: scan for anything with a level above zero. A detection is not a problem on its own, but it tells you what your water contains, which matters for workplaces with special needs, such as clinics.
Read the source column: “erosion of natural deposits” means the substance comes from the ground, while “runoff” or “industrial processes” point to human activity.
What a public report cannot tell you
The report covers water in the system, not water at your faucet. It cannot see the service line to your building or the plumbing inside your walls. A coffee machine at the end of an old pipe can taste different from the sample.
Lead is the standard example. It rarely comes from the plant. It comes from old solder and fixtures in the building. In 2025 the city tested 63 customer taps and none went over the lead action level. That is reassuring for the system, but it is not a test of your tap.
So the report is a baseline, not a guarantee for your faucet. If you have a concern about your building, test your own taps.
What water quality means for a workplace day to day
Water quality shows up as a metallic taste in the morning tea, white crust on the coffee machine and staff who bring their own bottles. These are small, daily and easy to ignore until they add up.
Not everyone in a building has the same needs. Clinics, schools and offices with older staff or young visitors often get more questions about what is in the water. Your utility’s report is the first place to look. A doctor or the health department is the place for medical advice.
Equipment is the cost you can measure. Scale builds up on heating elements in kettles, urns, ice machines and dishwashers, and descaling takes staff time. In the MWD zone, with hardness near 220 ppm on average, that effect is stronger than in the blended zone.
Health questions staff ask
Sensitive groups: infants, older adults and anyone with a weakened immune system sometimes need extra care with drinking water. The utility’s report has a note for people with weakened immune systems, and the right person to ask is their healthcare provider.
Skin and hair: chlorine and hard water are often blamed for dry skin. We have no data on that and will not claim it. What we can speak to is taste and the dissolved minerals in drinking water, which is what a filter on a dispenser works on.
Building and equipment
Plumbing: very aggressive water can corrode copper pipes. We have no data showing Long Beach water does that, so check your building’s maintenance records instead of guessing.
Taste and ice: high total dissolved solids can cloud ice and flatten tea. The 2025 report shows 280 ppm in the blended zone and 530 ppm in the MWD zone, so the drink and the ice can taste different across the city.
How to test the water at your own taps in Long Beach
The report does not cover your plumbing, so testing your own taps is the only way to be sure. A test also stops you buying equipment for a problem you do not have.
Many people skip testing because a pitcher filter feels like enough. A pitcher cannot tell you what is in the water. You may be filtering for chlorine when the real issue is hardness, or the other way around.
There are two routes: test strips and a certified lab. They differ a lot in accuracy, and the right one depends on what you need to know.
When to consider testing
Moving into a new space: test before you move in. Old pipes or solder in an older building are not something a standard inspection looks for.
A sudden change: a rotten-egg smell, a metallic taste or cloudy water means something changed in the supply or in your own line. Test, and tell the utility.
Test strips versus a certified lab
- Test strips are cheap and fast. They give a rough read on hardness and pH. They are not designed to find trace metals such as arsenic or lead.
- A certified lab sends you sample bottles, tests the water and returns a written result. It costs more, but it is the version you can rely on and keep on file.
For a Long Beach workplace with a real concern, we would pay for one lab test and keep the result as a baseline for later decisions.
Solutions for your workplace and the office water cooler cost per month
Once you know what is in the water, you can decide what to do. Many offices default to bottled delivery because it is easy to order. Others look at filtered dispensers on a water line and ask what the monthly cost would be.
Our plans start at $80 a month per dispenser* and cover the machine, free installation, scheduled service and repairs. Replacement filters are billed separately, about once a year. Your office water cooler cost per month depends on the machine and site. *Starting price; final pricing depends on the machine and site.
A dispenser only treats the water people drink, so it will not fix scale elsewhere in the building. If scale on equipment is the main problem, ask a plumber about treatment on that line. If taste is the issue, a filtered dispenser is the simpler fix and replaces the cost of bottle deliveries.
Treating water at one spot or for the whole building
Treating water at one spot means a dispenser or an under-sink unit. Ours filters through seven stages: sediment, pre-carbon, RO/UF membrane, pH balance, sanitization, nutrient boost, and taste and odor polish. It is for drinking water, not for the whole building.
Whole-building treatment sits where the water line enters the building and treats everything. A softener there protects pipes and equipment. It is a plumbing job, which we do not do, and the equipment is yours to own and maintain.
Comparing the cost of the options
Compare like with like. Ask each provider for the monthly price, the filter price and the term in writing. For delivered bottled water, check the quote for deposits, delivery fees and fuel surcharges.
Send us your last three delivery invoices and the number of people in your office. We will put a written quote next to them, and you can compare the two lines yourself.
Before you pay a monthly rate to anyone, get the filter price and the term in writing. Our term is set per site and confirmed in writing, and filters are billed separately.
Long Beach water myths and what the report says
Water rumors travel fast. The best check is the report itself, which lists what the utility found and what the legal limits are. If a claim about local water cannot be matched to a line in the report, be careful with it.
On the wells, the utility’s 2012 source water assessment says they are most vulnerable to sewer collection systems, and some also to gas stations, dry cleaners, underground fuel tanks and similar sources. The utility monitors every active well and says it has not detected any contamination.
A morning “sewer smell” at a sink is rarely the supply. It is more often a dry P-trap in a drain or a tired water heater. A plumber can tell you in one visit, which beats buying a filter for the wrong problem.
What to ask any water provider before signing
Ask whether the provider will put four things in writing: the monthly price, the filter price, the term and the service hours. Ours are set out above. Filters are billed separately about once a year, the term is set per site, and support runs Monday to Friday, 8 AM to 5 PM.
Ask also whether the filter handles chloramine and not only chlorine, and what the membrane removes. If a provider cannot name the stages in the filter, treat that as an answer in itself.
When a dispenser is the wrong answer
A small office with two people and a kitchen tap that tastes fine does not need a rental. If you only want to cut the chlorine taste, a countertop pitcher may do. We would say so on the phone.
We also cannot help if there is no water line within reach of the spot you have in mind, or if the building is a home. We rent to businesses only.

Community: how the city protects its water supply, and your part
The utility manages the groundwater basin carefully. Wells are built with a physical barrier around them, and the city monitors every active well. Keeping a basin healthy is a long-running job, and the report describes the pieces involved.
Businesses play a part. Medication and chemicals belong in proper collection programs, not down a drain, because wastewater plants cannot remove everything. Ask your building manager what the program is.
Staying informed is simple. The Board of Utilities Commissioners meets on the first and third Thursday of each month at 9 a.m. at 1800 E Wardlow Road, and the public can comment. You can also call the utility’s lab with questions on (562) 570-2479.
What a workplace can do
Fix leaks promptly and keep an eye on water use. Both lower the load on the system and on your bill.
Keep paint, oil and chemicals out of storm drains. Storm drains lead to local waterways, not to a treatment plant, so what goes in stays in the environment.
If you spot a leaking hydrant or notice a sudden change in taste or color, tell the utility. Staff on the ground notice things first.
What to take away from the 2025 Long Beach water numbers
Long Beach tap water in 2025 was 71 percent local groundwater and 29 percent imported, blended for most of the city. It met every standard in the report. What changes from one building to the next is hardness, which was nearly three times higher in the MWD zone than in the blended zone.
The report cannot tell you what your own pipes add. A test of your taps can. Between the two, you know whether you have a taste issue, a scale issue or nothing to fix. Then you can decide with facts.
If drinking water is the issue, a filtered dispenser costs a monthly fee instead of a delivery truck. What an office water cooler cost per month looks like for your site is something we quote in writing after a site visit, and the visit is part of the free 7-day trial.
Three things to do next
- Test your taps with a certified lab, not a guess.
- Decide what you need: drinking water treated at one spot, or the whole building.
- Ask for the price, the filter price, the term and the service hours in writing.
