Basically, the same will apply to areas where waste is dumped and burned or where fuel and other contaminants may get into the ground water, which will then become contaminated. Another thing to take into consideration is farms, where pesticides or animal waste could get into and contaminate the groundwater. As for sun or shade, it is best to make sure the area where the water well is being placed get plenty of sunlight. Most drillers would prefer to drill in the shade, however it is not the best location. Harmful pathogens can get on the soles of the feet of the people collecting the water. This is largely due to shade causing bacteria and algae to get around the well. Sunlight will help dry up the well surroundings daily and disinfect and kill the pathogens. Sanitary Seal: One aspect of drilling a water well is the fact that we would have to drill through the impermeable layer. This could cause an issue allowing contaminants to flow down from the polluted layer to the clean, second aquifer and then enter the well-screen. In order to prevent this from occurring, a sanitary seal must be used to seal up the impermeable layer. If only one aquifer exists, the sanitary seal must be at least 3 to 5 meters thick and must be installed above the gravel pack. By using an impermeable seal, it will help force the water to flow through the undisturbed soil, which will increase the travel time from the surface to the filter screen and gradually the pathogens will die off over time. Drilling Logs: drilling log is a written record of the geological formations (soil layers) drilled, “A according to These drilling logs will help determine the exact depth of the aquifers and depth.”
