A nitrogen contamination source never discussed and has never been a concern is the unregulated raw sewage that is pumped, transported and disposed throughout Florida, it is a substantial amount of raw sewage estimated to be around 2.8 BILLION gallons a year. Very little is known about where the raw sewage and its nitrogen goes after it is pumped.
If septic system sewage is not dumped in a state-approved facility, the state agencies do not recognize its existence, and it is definitely not included as a pollution or nitrogen contamination source to Florida’s waters. Florida does not have a program in place to track the transported raw sewage, or to know how many septic tanks are pumped, or if the 2 billion gallons of septic waste and it nitrogen is properly and safely disposed.
No one knows if Florida's 2 billion gallons of pumped septic waste is properly and safely disposed.
