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.

No afraid not. You can be the healthiest people on the planet but there is still e.coli in a septic system. In fact, if the grass is growing really well there, there may be some leaking going on.
WASTEWATER DISPOSAL BY SOIL ABSORPTION
Effluent from the septic tank flows by gravity or is pumped to a leach field for disposal. The wastewater effluent is absorbed by soil particles and moves both horizontally and vertically through the soil pores. The dissolved organic material in the effluent is removed by bacteria which live in the top ten feet of the soil. As the effluent moves through the soil, the temperature and chemical characteristics of the wastewater change and create an unfavorable habitat for most bacteria and viruses. Therefore, as the septic tank effluent moves through the soil, organic material and microorganisms are removed. The wastewater generally percolates downward through soil and eventually enters a groundwater aquifer. A portion of the wastewater moves upwards by capillary action and is removed at the ground surface by evaporation and transpiration of plants.
