Water Dominates Our Planet
71%
of Earth’s surface is covered by water
Water shapes climate, ecosystems, and every supply chain humans depend on. Yet most of it is not drinkable. Rough breakdown:
- ~96.5% is saltwater in the oceans.
- ~2.5–3% is freshwater.
- <1% of total water is readily accessible freshwater in lakes, rivers, and the atmosphere.
Numbers rounded from widely cited hydrologic inventories (e.g., USGS).
Why this matters for homes and businesses:
- Surface and groundwater quality varies by region and source.
- Treatment needs differ: sediment, hardness (minerals), organics, microorganisms, and specific contaminants.
- Right-sized filtration and disinfection improve safety, taste, and equipment lifespan.
Earth is a water world, but usable freshwater is limited. Effective testing and targeted treatment turn a global statistic into reliable water at the tap.
