No. Fresh water is simply water that is not noticeably salty.
The stream was unpolluted and clean. The ground was unpolluted with the toxin.
Hydra do not have an endoskeleton. They are multicellular organisms that can be found in unpolluted fresh-water ponds, streams, and lakes.
If water is unpolluted, fish thrive in it.

It depends where it is.
Aqueducts were water conduits which supplied fresh water to the cities. They carried it from the water sources on the mountains. The word comes from aqua (water) and duct (A channel or tube for conveying something). Most of them were underground pipes. The conduits were also placed on bridgework when the aqueducts had to cross valleys or when they were needed to maintain a gradient as they relied on gravity to make the water move.
Mountains have fresh water because they act as watersheds, collecting rainfall and snowmelt that then flow downstream as rivers and streams. The water in mountains is often pure and unpolluted because it comes from natural sources and has not been extensively processed or contaminated by human activities.
The pH of unpolluted rainwater is typically around 5.6, which is slightly acidic. This acidity is primarily due to the presence of carbon dioxide in the atmosphere, which forms carbonic acid when dissolved in water.
because fresh water is dirty and if you drink it you'll shrivel up and die Not always The water might be polluted or they may want water that has been as cleaned and unpolluted as possible. Everyone is told that it is healthier to drink bottled water, but who really knows for sure. Some people probably think about all the fish swimming in it or about people bathing OS swimming in it.
To keep water unpolluted, you can: Properly dispose of waste by recycling and using designated disposal sites. Avoid using harmful chemicals and pesticides that can runoff into water sources. Support and participate in clean-up efforts for rivers, lakes, and oceans.
