Windmills, like the Aeromotor, Dempster and Baker, have enjoyed a successful career in pumping water by mechanical energy from wells for livestock and homesteads throughout the United States for more than 100 years.

The wells fitted with the Aeromotor and Goulds pumps showed somewhat lower pH, hardness, conductivity, and alkalinity than the other three wells, although these differences were considered too minor to have a significant effect on the lead-leaching results.

Only the Sta-Rite, Aeromotor, and Goulds pump results are shown, because the other two pumps exhibited essentially undetectable lead concentrations.
Of the three leaded-brass models, the field studies showed more rapid and continued concentration decreases over time for the Sta-Rite and Goulds models than for the Aeromotor pump, which, over the extended field usage period, appeared to stabilize at overnight dwell concentrations of approximately 3 [[micro]gram]/L.
