1. Calculate the BOD loading (lbs/day) on a pond if the influent flow is 390,000 gpd with a BOD of 245 mg/L.

Don't get confused with this book. All you need for morning section is CERM.

"While a master's degree does provide valuable education" Can you elaborate more about this? What is "valuable education"?

PE Hope, Where do you see the posting of license numbers? Can you post the link of website?
