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.
