Understanding how water systems work helps us protect them—and ourselves. Learn how water flows, what to watch for, and how your actions make a difference.
Water doesn't just affect us — we affect it.
The same conditions that make water unsafe for swimming can also damage ecosystems:
Low oxygen levels
harm fish populations
Nutrient runoff
fuels algae blooms
Chemical imbalances
disrupt aquatic life
H2gO helps make these invisible connections visible.
Water flows downhill, carrying whatever it picks up along the way
Fertilizers and pesticides enter groundwater
Runoff flows into local streams
Contamination travels downstream
Your recreation area affected
See how upstream farm activity affects downstream recreation areas
Heavy fertilizer application
Farms apply nitrogen-rich fertilizers to crops in spring
Rain event follows
2 inches of rain washes excess nutrients into streams
Nutrient spike detected
Monitoring stations detect 3x normal nitrate levels
Apple Canyon Lake affected
Elevated nutrients reach the recreational lake
Algae growth begins
Warm temperatures + nutrients = potential algal bloom
H2gO alerts you first
Get notified before conditions become unsafe
Even small choices can influence water systems.
Products like certain sunscreens, fertilizers, and runoff can:
H2gO encourages informed decisions—not just for safety, but for sustainability.
You don't need a lab to notice when something feels off.
H2gO combines environmental data with real-world observations.

Your eyes on the ground help everyone stay informed
Community reports improve accuracy for everyone
Because understanding water shouldn't rely on getting sick first.

Knowledge is protection—for you and your community
Know about potential contamination before it reaches your favorite swimming spot. Get alerts based on upstream conditions.
Understand where water quality issues originate. This knowledge helps communities address problems at their source.
Protect vulnerable populations by providing advance warning of water quality changes from upstream events.
