I concur with the other comments. Storm water will likley increase turbidity, erode soil, and flush various sources of fecal contaminants into the drinking water source. Should there be any chemicals stored in the affected area, these could also flush into the drinking water source. Dependending on the source of drinking water, river, lake or groundwater, will determine your course of action to protect it. Some plants will shut down until flood waters receed. This requires planning and storage if storage is availble such as water tanks. I hope this helps.
