Stream water samples were taken from the North-West Ireland and were tested for their chemical make-up. This allows us to map water quality and learn about what rocks they flow through.
Knowing about the chemistry of stream waters is important for many people and industries. Farmers need to know the chemistry of surface water to understand the quality of water sources and its impact on soil and crops. This helps them decide if they should use water purification or not. This can improve the health of their animals and quality of their crops. Rocks can affect the quality of drinking water. Quality of water is important for many industries and individuals such as inland fisheries or farmers. If water is affected, it may need to be treated before it can be drunk by people or animals. The chemistry of surface waters can also help people looking for minerals (materials taken from the ground used for things we need from mobile phones to the stones used to build roads and houses). |
