Frequently Asked Questions

Have questions about ESKA spring water? We have answers!

Below are the questions we are most commonly asked about ESKA spring water, our products and packaging, our distribution network and our activities.

  1. Is ESKA spring water naturally carbonated?

    ESKA water is not naturally carbonated. A small amount of carbon dioxide is added to the water at the time of bottling to lightly carbonate it without adding sodium.

  2. Do you add ozone to ESKA water?

    We do not add ozone to our water. ESKA water comes from a natural underground spring and requires no chemical processing prior to being bottled. At the Saint-Mathieu-Lac-Berry esker, the water is naturally filtered through the sand and rocks. The result of this natural filtration process is water that is microbiologically pure, low in mineral content, and kept cool at 5°C, a temperature too low for bacteria to exist.

  3. Do you add fluoride or chlorine to ESKA water?

    We do not add fluoride or chlorine to our water. Despite some controversy surrounding the fluoridation of public water systems, fluoride is a naturally occurring substance found in many of the world’s water sources that are not inherently toxic. Moreover, the fluoride concentration in ESKA water (0.1 part per million) is very low. If you check the mineral composition chart on our label, you’ll see the entire mineral content of our water.

  4. I conducted my own pH test on my bottle of ESKA water, and the result was higher/lower than 7.8, the amount indicated on your labels.
    How can this be?

    Our quality control department conducts regular pH tests on our water. The 7.8 value on our label is an average and is based on our test results over an extended period of time. We therefore cannot guarantee that a bottle sampled at random will have an exact pH value of 7.8.

  5. I see small particles floating in my water. What are they? Is the water safe to drink?

    Most of the time, these small white particles are crystalized calcium. Under certain conditions, the calcium in the water will crystalize if the water freezes during transport, for example. Once the water thaws, these crystals may remain in the water, which explains the small white particles you see. These crystals do not affect the quality of the water, nor do they pose a health risk.

  6. What formats does ESKA come in?

    Taste the purity of ESKA Natural Spring Water, shaped by Canadian glacial rocks. Simply choose the category of natural spring water you prefer and find out about all the available formats by visiting our product page.

  1. Can I have ESKA bottled under my own label?

    Unfortunately, we are unable to accept requests for private labelling at this time.

  2. Your labels say “Return for refund where applicable.” Where can I bring my bottles for a refund?

    Our bottles are indeed eligible for refund where applicable. Deposit refund programs vary from province to province in Canada and are often linked to the recycling programs in place in each region. Currently, all provinces with the exception of Quebec, Ontario and Manitoba have deposit refund programs that accept bottled water containers. To find out more, check into the deposit refund policy in your province and your local recycling program.

    All ESKA water PET plastic bottles, glass bottles and aluminum cans are 100% recyclable. If you live in a province that does not offer a deposit refund program for water bottles or cans, we encourage you to dispose of them in a recycling bin.

  3. What kind of plastic do you use in your bottles?

    Our bottles are made of polyethylene terephthalate (PET) plastic, a material that is 100% recyclable and approved for use in beverage containers by organizations such as the Canadian Bottled Water Association.

  4. Do your bottles contain bisphenol A (BPA)?

    No, our bottles do not contain any bisphenol A (BPA). They are made from polyethylene terephthalate (PET) plastic, a material that’s 100% recyclable and approved for use in beverage containers by organizations such as the Canadian Bottled Water Association.

  5. What does the circled letter “U” followed by a “P” on your labels mean?

    The encircled “U” on our labels designates that our water is considered kosher and pareve by the Union of Jewish Orthodox Congregations. The “P” following this symbol indicates that the product can be used for Passover.

  6. What does the MK symbol on your labels mean?

    The MK symbol certifies that our products are kosher. This certification is awarded by the MK-Canada Kosher Certification Agency.

  1. Where can I buy ESKA water in the United States?

  4. I am interested in providing professional transport services for ESKA. Whom should I contact?

    If you are interested in transporting ESKA water, please send your complete contact information to and include the regions served by your company. We will forward your inquiry to one of our representatives.

  1. What do the snowflake, stone and drop of water represent in the ESKA logo?

    These three components represent the natural filtration process of ESKA spring water:

    • The snowflake symbolizes the origins of ESKA spring water. Whenever it snows or rains, the water that accumulates on the forest floor penetrates through the soil and flows into the esker’s underground formations.
    • The stone symbolizes the meticulous, natural filtration of ESKA water by the glacial rocks in northern Quebec. Over a period of more than 15 years, the precipitation that collects from snow and rainfall is gradually filtered through the layers of rock, sand and gravel found in the esker, far removed from human activity.
    • The droplet of water represents naturally pure ESKA spring water, harvested directly at its source. ESKA water, pristine and fresh in taste and content, is the result of the esker’s unique filtration system.
  2. Can I visit your bottling facility in Saint-Mathieu-d’Harricana?

    It is now possible to visit the bottling facility of ESKA water. Visits are made by reservation only, from June 25 until September 15. For more information and to make a reservation, please call (+1) 819-727-1242 or visit

    We also invite you to pay a visit to the Pavillon d’interprétation de l’esker. This tourist pavilion, which is near our facility, offers a wealth of information about the formation of the esker, its ecological role and the ESKA Natural Spring Water bottling process. You’ll also have the chance to draw water that comes directly from the ESKA source and enjoy a picnic in the pavilion grounds. The pavilion is open from May 15 to October 15. To learn more about this fascinating venue, please visit (French language website).

  3. Where can I find the expiry date on my bottle or case of ESKA water? How should the expiry date be read?

    The expiry date on our products is part of our production coding, which is used to trace the production information for our product. This two-line coding is printed on each individual bottle as well as on the packaging of all of our cases, and we use ink approved for use with food items. The coding is interpreted as follows:

    353 12:19 00021
    L1 2015/DE/19

    353: Production day (Julian day number)
    12:19: Production time
    00021: Lot number (5 digits)

    L1: Production line
    2015/DE/19: Expiry date (DD/MM/YY).

  4. Is ESKA a Canadian company?

    The ESKA brand is owned by ESKA Inc., a privately owned Canadian company with its corporate offices in downtown Toronto. The company’s bottling facility is located in Saint-Mathieu-d’Harricana. ESKA Inc. employs approximately 130 people in Quebec and Ontario.
