He is CONSTANTLY dealing with raw sewage complaints... So he knows those rules pretty well.I am only retelling what I was told by a pumper serviceman a number of years ago. I don't remember the exact number of years between dumping, when safe to graze cattle, and when safe to grow food. But that is the system they had in place - he told me that maybe 3 years ago at the last time I had my septic tanks pumped.
According to my source of instant knowledge, Alexia, she reports that it takes 2-3 years for human sewage to become safe for growing food - depending on the weather where the sewage is dumped. That timeframe sounds about right from what I was told by the pumper truck guy.
When I was in the navy, we visited a number of third world countries where they grow their food in fresh human manure. When we pulled into a foreign port and bought fresh food and vegetables from those countries, we would have to clean them in a bleach wash before cooking. It was safe to eat after that, but none of us liked the thought of eating food grown in human manure.
But if DH is in the health department, he is probably much more current on the rules and regulations pertaining to human waste here in the US. I know the home septic system requirements where I live have changed a number of times over the years and any time we want to make improvements on our property with new structures, we have to get our septic system recertified before building.
I live on a lake, and our septic requirements are the highest standards on the books. I agree with high requirements. Everybody wants clean water in the lake.
I'm not saying YOU were in the wrong or casting doubt on what you were told. That's probably what they are doing... And the worker may not even be aware that it's illegal. You'd be shocked at what people and companies do with sewage. Even our own Dept of Corrections got fined this... Crazy.
On a personal note, I do occasionally put diluted urine in the compost although never directly on the garden itself even though I know many people do. Urine is supposed to be sterile and debatably safe for use in the garden. Human feces, on the other hand, are not sterile or safe. There are outbreaks of e.coli and other pathogens that can be linked to sewage use. No thanks. Not worth it to risk my family or financial liability that way when there are a gazillion other forms of safe fertilizer I can use instead.
