Contaminated water such as polluted water can sometimes cause an explosion of new plant growth by providing necessary nutrients and food and at other times it can kill or harm plants such as by raising or lowering acidity. Plants need at least good levels of potassium, nitrogen and phosphorus for healthy growth and by corollary, biodiversity. I believe that water which contains these elements, even if it be contaminated with the right contaminants will aid in biodiversity by enhancing growth. On the other hand, if there is too much salt, for example in the water it will prevent growth and inhibit photosynthesis.
