A lagoon has an average daily flow of 0.25 MGD. How many gallons per day is that?

• A. 200,000
• B. 300,000
• C. 250,000
• D. 350,000

Answer: (C)

MGD means million gallons per day. To find gallons per day, multiply by 1,000,000. So 0.25 MGD equals 0.25 × 1,000,000 = 250,000 gallons per day. Since 0.25 is a quarter, this is a quarter of a million, i.e., 250,000. Therefore, the lagoon’s average daily flow is 250,000 gallons per day.

MGD means million gallons per day. To find gallons per day, multiply by 1,000,000. So 0.25 MGD equals 0.25 × 1,000,000 = 250,000 gallons per day. Since 0.25 is a quarter, this is a quarter of a million, i.e., 250,000. Therefore, the lagoon’s average daily flow is 250,000 gallons per day.
