Did you dig deep enough to get what I'm saying though?I did some research on the topic and I have found some answers to your questions.
Lets start at the beginning. At the aquifer map you linked to there are links to more detailed aquifer information on almost all counties in IN. I'll take a random sampling of some counties and post relevant information. I am not cherry picking counties, I will pick a county, and post the data, even if it goes against the point I'm trying to prove.
Adams county: 79% of wells are bedrock (I would wager that most, if not all of those that aren't bedrock based are not used for potable water for human consumption)
There are 2 main aquifers in Adams County.
#1: Typical well depth is 90-160 feet, static water levels are commonly 20-50 feet.
#2: Typical well depth 115 to 385 feet, static water levels are 35-40 feet.
Lawrence County: there are 4 main aquifers
#1: Typical well depth is 60-350 feet, but deeper wells may be required to obtain adequate water supply, static water levels typically range from 10 to 100 feet (once again, probably towards the deeper end for adequate supply)
#2: Most wells are 140-260 feet, static levels are commonly 20-275 feet
#3: Most wells are 95-175 feet deep, static levels are commonly between 20 and 80 feet.
#4: most wells are 60-140 feet, static water levels are commonly 10-60 feet. (possibly viable, but I wouldn't risk the reliability)
White: 4 main aquifers
#1: No well/water depth data available other than it's listed as shallow and has a moderate risk of water contamination
#2:Most wells are 55-70 feet, static levels range from 10 to 30 feet (this is the first truly viable option for a pitcher pump as your static water level is sure to be within pumping range, although it may take some priming)
#3: wells 50-100 feet, static water level 5-15 feet (another prime example for pitcher pump)
#4: 70-165 depths, static water levels 7-40 feet (possibly viable)
All that data can be found online. But I think it proves my point very clearly. Out of 3 counties I examined, only 1 of them is actually viable for using a pitcher pump, and out of that 1 of the 4 aquifers has a moderate risk of contamination because it is so shallow.
So looking back on that, very few wells in IN are shallow enough (static water levels) to be able to support a pitcher pump. And of those that are, some are likely contaminated because of the shallow water table. The cleanest water is going to come from the deep wells, and you just can't use a pitcher pump for those wells.
