Usually in filtered ⁴ water there tends to be ions

Water is “softer” when it is treated. Usually in filtered water, there tends to be ions like sodium for taste. Whereas in “hard” water there are more metallic ions like Mg 2+ and Ca 2+. In this group, it is expected that the water from outdoors and off the concrete will be the hardest. This is due to rain and runoff. If the water had been evaporated from ground water and bodies of water around State College, it would be the least filtered, therefore having the most cation concentration. After this, it would be expected for the shower water to be less concentrated than the runoff, but more concentrated than the drinking water. Finally, the tap water from the sink would be the least concentrated. This is expected because the sink water is the only one expected to be ingested out of the four. Thompson S.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
