(A) nutritional runoff

Explanation:

According to my research on algal bloom, I can say that based on the information provided within the question this was probably caused by nutritional runoff. This term is defined as the process in which too many nutrients are introduced to a certain body of water causing it to act like a fertilizer which in term causes an excessive growth of algae.
