    yep a very special one underground because its filtered by all the dirt and is usually clean enough to drink or water crops with

    We typically pump water up from the aquifer not in to it.

    In fact sometimes its illegal to pump water from the surface back in to the aquifer

    6.3 is almost neutral and often times well find that surface water is slightly acidic anyways so 6.3 is a healthy ph for a stream

    In the last 50 to 75 years we started using petroleum products mined from deep inside the earth to initiate a chemical reaction that takes nitrogen from the air and creates a chemical that looks a lot like salt. That chemical version of nitrogen is vital for plant grow and we realized that we could apply it to our crops and it would make our plants grow super big. Now farmers use it a lot and somtimes it ends up in our lakes. Well algea can grow off this nitrogen too. Like all plants the algea also needs oxygen inside the water. So when a lake gets polluted with nitrates a ton of algea gros, the algea uses all the oxygen in the water and then the fish and other aquatic life is left with very little oxygen to survive.

    There are approximately 1,386 million cubic kilometers (km3) of water on Earth. Approximately how much of that total is saline? 4,158,000 km3 41,580,000 km3 134,442,000 km3 415,800,000 km3 1,344,420,000 km3
