Healthy soil and sustainable growing

["E. E. Mitchamore Jr" <emitch@att.net>]

Here in Central Texas, the biggest aquifer, the Trinity Sands, is around 500' - 600' deep, so it's pretty clean.  However, wells are not cased all the way down, so a well can be contaminated by a shallower aquifer.  Local tests have shown that the limestone karsts can conduct pollutants into the shallower aquifers in three days.  From there into springs and wells.

Deep wells are generally pretty safe, at least in most rural areas. This with a caveat regarding aquifer pollution. I worked on one project in Ohio where the aquifer was contaminated by a uranium processing plant. One also needs to be careful about nitrates and pesticides in agricultural areas. Near urban areas leaky underground gasoline storage tanks can be a problem but in this case the odor of petroleum products is generally obvious. It is a good idea to learn about your local aquifer and what potential sources of pollution may affect it.

I grew up on a farm with a well.  I am assuming that there is no runoff [surface water] running into the well.  That being the case, any contaminates would have to infiltrate the soil and go down through the soil to the water level.  I believe that will be nearly impossible unless the water is very, very, very shallow.
