How Water Quality Shapes Gold Medal Surfaces
When we watch the Winter Olympics, we see speed, precision, and incredible skill on ice. What we don’t see is one of the most important pieces of “equipment” every athlete relies on: the water that becomes that ice. At the Olympic level, ice is engineered with the same care as skates, stones, and skis. CWQA proudly recognizes Jet Ice, one of our valued members and a global leader in ice-making technology, for their pivotal contributions to these venues.
Jet Ice, along with top researchers at Toronto Metropolitan University, shows how water science, engineering, and real-time monitoring come together to make top-notch competition surfaces. From speed skating ovals to curling sheets, Olympic ice is engineered from the water up.

This article explores how water chemistry and treatment shape ice for hockey, speed skating, figure skating, and curling. Learn how water professionals play a quiet but vital role in every Olympic Games.
Why Water Quality Matters for Ice
Ice may look simple, but it is a complex material. Small changes in water chemistry can significantly affect how it freezes, its strength, and its response to pressure.
Research from Toronto Metropolitan University’s Jet Ice Research Chair shows how minerals, gases, and impurities can become trapped during freezing. This process directly affects ice clarity, strength, and friction.
These studies show that elevated levels of total dissolved solids (TDS), dissolved gases, and particulate matter can weaken ice structure and reduce its durability.
Key water quality factors include:
-
Total dissolved solids (TDS)
-
Hardness (calcium and magnesium)
-
pH
-
Dissolved gases (oxygen and carbon dioxide)
-
Particulates and organic matter
High TDS levels, often from calcium, magnesium, or iron, can trap impurities in the ice. This leads to cloudy ice and weakens its surface. Dissolved gases can form microbubbles, reducing strength and affecting resurfacing quality.
At the Olympic level, water treatment is subject to strict control. This often includes filtration, softening, reverse osmosis (RO), deionization (DI), and degassing. Continuous testing and change ensure that water remains within precise targets for each sport.
Hockey
Olympic and international hockey surfaces must balance speed with safety. Players need fast glide and reliable edges. They also need ice that can withstand powerful stops, turns, and collisions. Water quality helps achieve this balance:
-
Moderate TDS for better hardness: High TDS can make ice cloudy and lead to too much snow. Ultra-pure water, however, can create ice that is too soft.
-
Controlled hardness and pH: Hard fill water affects how ice bonds and reacts to temperature changes. Conditioning helps keep ice consistent throughout games.
-
Low particulates and dissolved gases: Filtration and degassing cut down bubbles and weak spots. This boosts puck bounce and reduces chipping.
For athletes, this means better puck control, predictable edges, and fewer late-game surprises.
Speed Skating
Speed skating is where ice becomes almost a laboratory product. Skaters race on long, thin blades. Even tiny changes in texture or friction can affect medal results. For speed skating ice, organizers focus on:
-
Dense, uniform ice: Treated water forms a steady crystal structure across the oval.
-
Low but controlled friction: Steady TDS and gas levels keep things fast and consistent.
-
Tight thermal control: Treated water freezes more predictably, helping manage temperatures precisely.
Water treatment and refrigeration work together as one system. This is a key feature of Olympic ice engineering.
Figure Skating
Figure skaters need ice that can handle strong jumps and multiple landings in the same spots. Water quality helps tailor figure skating ice by:
- Allowing for “softer” ice: Figure skating ice is usually a bit warmer and less hard than speed skating ice. This helps cushion landings and lowers the risk of injury.
-
Reducing bubbles and inclusions: Purified water limits defects that lead to cracks or chips.
-
Improving visual clarity: Advanced filtration makes clear ice, which helps judges and spectators see better.
Starting with properly treated water allows facilities to fine-tune rink conditions for figure skating performance.
Curling
Curling ice is special because of its “pebble.” This is made up of thousands of tiny frozen droplets sprayed onto the surface. For curling:
-
Very low TDS water for pebbling: RO or DI water supports uniform pebble formation.
-
Controlled pH and hardness: Stable chemistry ensures consistent stone behaviour.
-
Minimal gases and particulates: Reducing bubbles and particles prevents premature pebble breakdown.
The result is predictable curl, speed, and shot control. This is essential at elite levels.
Behind the Scenes: Continuous Precision
Water treatment and ice maintenance teams work in constant feedback mode across all Winter Olympic ice sports.
They regularly:
-
Test fill and resurfacing water for:
-
TDS
-
Hardness
-
pH
-
Conductivity
-
Alkalinity and dissolved gases
-
-
Adjust treatment systems (filtration, softening, RO/DI, degassing)
-
Monitor glide, grip, snow production, and chipping
-
Modify flooding volumes, temperatures, and maintenance schedules
It is a continuous cycle: measure, adjust, observe, repeat. Beginning with the quality of the water.
Olympic Ice and Canadian Innovation
As the Milano–Cortina 2026 Games unfold, CWQA proudly recognizes Jet Ice for its leadership in Olympic ice technology and research-driven innovation.
Through partnerships with Toronto Metropolitan University, Jet Ice helps advance:
-
Consistent hardness
-
Minimal friction
-
Optical clarity
-
Improved durability
-
Enhanced athlete safety
Clear, stable ice also allows painted lines and logos to remain visible beneath the surface. This is critical for broadcast quality and competition standards. This research-driven approach highlights how water science directly supports elite performance.
Why This Matters
For the Canadian Water Quality Association and its members, Olympic ice is a high-profile example of a simple truth: better water creates better ice for your drinks. The same principles apply to:
-
Community arenas improving performance and reducing energy costs
-
Curling clubs pursuing consistent play
-
Multi-pad facilities planning infrastructure upgrades
Expert water treatment improves performance, safety, and reliability. While often reducing long-term operating expenses. As Canadians cheer for Team Canada at Milano–Cortina 2026, every clean landing, sharp edge, and perfect curl takes place on ice engineered from the water up.
Behind that ice is the science, innovation, and expertise of water quality professionals, and the leadership of CWQA members like Jet Ice.
