Calcium carbonate is a chemical compound with the chemical formula CaCO₃. It is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snail shells, and eggshells. In 1989, a researcher, Ken Simmons, introduced CaCO₃ into the Whetstone Brook in Massachusetts. His hope was that the calcium carbonate would counter the acid in the stream from acid rain and save the trout that had ceased to spawn. Although his experiment was a success, it did increase the amounts of aluminium ions in the area of the brook that was not treated with the limestone. This shows that CaCO₃ can be added to neutralize the effects of acid rain in river ecosystems. Currently calcium carbonate is used to neutralize acidic conditions in both soil and water. What a wonderful discovery to benefit the world! However, why aren’t people know about it and use it to neutralize the soil, rather than relying chemical processes, which may be health hazard.
