When I was an undergraduate I did an experiment with some classmates in a blant biology lab class related to this question. We collected soil from two areas: one area that received drainage from a local copper mine, and one close area that didn't receive the drainage. We put the soil in water to extract the contents and used the water to water some wheatgrass seeds. The grass watered with the extract of the drainage soil was different in color, shorter, and had fewer root hairs, as I recall. In other words, it was less healthy. In our experiment, then, the type of water definitely had an effect on the growth of the grass.
Output:
does the type of water have an effect on grass growth?
