Protection of natural resources

Preservation of the land surrounding the esker and the source

The ESKA natural spring is located on a large site in St-Mathieu-d’Harricana in northern Quebec. Protecting the land surrounding this water resource is of paramount importance to us. In fact, to further ensure its protection, Quebec’s Ministère de l’Énergie et des Ressources naturelles declared a 4,25km2 area around the source as a “protected territory.”

This controlled, extensive forest perimeter enables us to protect the esker and all of the spring’s recharge zones, some of which are quite far from the water collection point. This entire area therefore comprises an environment that’s both undisturbed and strongly protected from external contaminants, unlike a spring in an agricultural zone or closer to urban centres.

In Quebec, many regulations also stipulate the boundaries that must be established around a water collection point to protect the ecosystem. Our natural resources protection practices actually exceed government standards, because we have made it our priority to preserve the rich natural heritage that the province offers.

Our approach to sustainable production

Although the spring is continually replenished, owing to its high recharge capacity along with the rain and snow accumulation, ESKA has set itself a mandate to respect the esker’s natural cycles by extracting only moderate amounts of water. Indeed, we harvest between 3-5% of the source’s annual recharge.

We also work with an independent team of hydrogeologists to assess the effect of our activities and ensure the sustainability of the natural source.

Since our founding, the decisions we make have reflected our goal to protect the natural environment. Day in and day out, the esker produces exceptionally pure water, and we want to ensure this continues.

Limiting soil contamination at all costs

To protect the esker, the parking lot at our production unit adjacent to the spring has been paved with cement rather than asphalt containing tar, in order to reduce the risk of leaching into the esker. A membrane was also installed around the production unit and under the parking lot to stop impurities from infiltrating. Every day, ESKA applies the latest technology to protect nature and the esker.

We also work in close collaboration with regional authorities to minimize any sources of soil contamination near our protected territory. For example, in winter the roads in the town of St-Mathieu-d’Harricana are de-iced with sand and gravel rather than salt.

Regular analyses of the esker

To ensure that the esker is able to continue its work and create the purest possible water, we need to protect it. We monitor it constantly and conduct regular analyses to measure its level and flow and safeguard it from all types of contamination.

Our analyses are carried out using 10 permanent pressure sensors installed in accordance with authorizations granted by the Ministère du Développement durable, de l’Environnement et de la lutte contre les changements climatiques (MDDELCC). These sensors measure fluctuations in both the spring and esker to confirm that the amount of water removed respects the water balance of the source and ensures its sustainability.


We are meticulous in our selection of the materials used in our products. ESKA bottles are made from glass or polyethylene terephthalate (PET) plastic, while our slim cans are made from aluminum—all three materials are 100% recyclable.

PET plastic bottles

Many ESKA water bottles are manufactured with polyethylene terephthalate (PET or PETE), a recycled material approved for bottled water by the Canadian Bottled Water Association. We use only top quality PET, as indicated by the stamp under each of our bottles.

PET presents no health risk as it contains no BPA (bisphenol A), an industrial chemical used in the manufacturing of rigid plastics.

Glass bottles

We use glass bottles for ESKA spring water in 355 ml and 750 ml formats. These bottles are 100% recyclable, as glass can be reused indefinitely without compromising its quality or purity.

All glass containers are recyclable, regardless of whether they carry labels. They are also refundable in some provinces.

Aluminum slim cans

ESKA slim cans are made of aluminum, which can be recycled and reused indefinitely without compromising its quality. All aluminum containers can be recycled.

Our environmentally responsible commitments focus not only on the natural surroundings but also on the nearby communities.
