Garden down slope from leach field?

[GaryM]

On the new homesite, the leach field is up hill from a prospective garden site. Would it be a no no to put the garden where the effluant could be moving through the ground water?

There are other usable garden sites, but this one has the most usable area.

Would probably be growing tomatos, peppers and such. In some countries human waste, nightsoil, is used as fertilizer.

Personally, I don't think it would be a problem unless you were really close (like 10-25 feet) and if the system was not working properly..i.e. the sewage was running out of the field at ground level.

A drinking well only needs to be 100 feet from a leach field here in Mass, and it is drawing from water *beneath* the level of the leach field.

How far away is your field from the proposed garden?

[GaryM]

Nearest part of the garden should be about 50-60 feet away. Perhaps farther if I make it long and narrow rather than square.

If your system is working OK you should be fine. Most of the water flowing into the leach field will either evaporate up or go down, not much should go sideways.

Thats plenty far away...unless your septic system is really disfunctional, I can't see any problem.

Thanks for the input. I guess I won't have to irrigate.

That sounds plenty far enough that you shouldn't have to worry about it. The septic tank cleans most of the nasty stuff out - the leach field water shouldn't be all that bad (from a well balanced tank it should be mostly treated grey water).

The majority of that will evaporate anyway.

Yeah, it will. And the stuff that doesn't isn't all that bad as far as quality is concerned. Bet there are city systems that don't deliver water much cleaner than that... Even heard that some of the bottled waters are full of nasty stuff. But that far from the septic tank should be just fine for a garden.

How far away?
My garden is only about 75 feet away from my drain field. I haven't had a problem yet (that I know of).

Only after it has been very well treated.
