There are two hand dug wells at BOL 2.
One is the old type you see in movies where you lower a bucket (20 ft) it was put in when Texas was part of Spain. It has been filled in but could be duplicated. The other is also hand dug and filled (@30 feet) and was from the 1960's when there was a small farm house there, but, we haven't found that one yet.
The creek is spring fed but the water downstream is rusty brown from the leeching of the iron laden rock into the water. Too much iron consumed can lead to Hemochromatosis and be damaging to the organs. That water would be better for irrigation rather than drinking.
The well at BOL1 is a typical modern well and @455 feet must have a pump. The neighbors dug a new well a few years back when they went dry during the drought and had to go to 1000' (955' to be exact) to find good water. The first well, they hit was at 500' and was too high in Barium. Even community wells might not be safe.
Investigation Finds Radiation in Texas Drinking Water
My husband's family has owned a well drilling/digging business since 1850 and they have always talked about how a bad well can make people sick with everything from tummy trouble (Coliform bacteria) to cancer. They pride themselves in drilling safe wells.
If you plan on digging a well and using it as your primary source of drinking water for any length of time, or giving it to small children or pregnant women, it is a good idea to take the extra step of having it tested. Waiting until TSHTF will not be practical.
