We've moved into a property and I am looking to start my first veggie
patch, but we discovered our sewage pipe has a small leak and so sewage
water has been leaking out of a small hole, approx 8 foot from the
veggie patch area and about 3 foot from our vine. Does this mean all
produce will be contaminated? How can we make the area safe for growing
again? Thanks in advance for any guidance.

Vegetable Gardens and Drainage Fields
Sometimes the ideal place to put a vegetable garden seems to be over the
leach field, raising the question of bacterial and viral contamination
from the effluent. Soils vary a great deal in their ability to filter
viruses and bacteria. Clay soils work best, eliminating bacteria within
a few inches of the drain trenches, but sandy soils may allow bacterial
movement for several feet. A properly operating system will not
contaminate the soil with disease-causing organisms, but it is very
difficult to determine if a field is operating just as it should. If at
all possible, use your septic drain field for ornamentals and plant your
vegetables elsewhere. If you must plant vegetables, take the following
precautions. Do not plant root crops over drain lines. Leafy vegetables
could be contaminated by rain splashing soil onto the plant, so either
mulch them to eliminate splashing or don't grow them. Fruiting crops are
probably safe; train any vining ones such as cucumbers or tomatoes onto
a support so that the fruit is off the ground. Thoroughly wash any
produce from the garden before eating it. Do not construct raised beds
over the field; they might inhibit evaporation of moisture.

Can I plant a vegetable garden over the
leach field?
It is tempting to consider placing a fruit or vegetable
garden over the leach field, to take advantage of
the extra moisture and nutrients provided by the in-
ground effluent. However, it is not recommended
that vegetable gardens be planted over leach fields
due to potential health hazards and possible
damage to the leach field itself.
One of the greatest concerns when planting a
garden over a leach field is the potential for
contamination of soil and produce by disease-
causing pathogens, such as viruses and bacteria.
Never plant root crops over the leach field.
Pathogens can be expected to travel short
distances through the soil, especially in sandy soils.
Root crops, such as carrots and potatoes, that grow
in the soil are the most likely to pick up
contamination from the area above or downhill from
the leach field. It is not possible to determine if a
crop has been contaminated by its appearance.
Leafy crops that grow close to the soil surface
could also experience contamination from irrigation
water splashed onto the foliage. The taller the crop,
and the greater the distance from the ground, the
lower the risk of contamination.
Before proceeding with a vegetable garden over a
leach field, consider a few other things. If you have
a water softener, chances are your system adds
salt to the septic system every time it regenerates.
The salty effluent water released into the garden
area could harm salt-sensitive plants, such as
beans and peppers. You also need to consider the
other household chemicals you use and their
possible effect on plants and produce.

Every gun that is made, every warship launched, every rocket fired signifies in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed. This world in arms is not spending money alone. It is spending the sweat of its laborers, the genius of its scientists, the hopes of its children. This is not a way of life at all in any true sense. Under the clouds of war, it is humanity hanging on a cross of iron.
