|Among the Water Survey's most important public services are the water analyses provided by the Chemistry and Technology section to citizens of Illinois who own private wells. The Public Service Laboratory (PSL) has a long history of testing well water samples and making recommendations for water problems of all kinds, whether they cause health or economic difficulties, or whether they're simply a nuisance. The data generated by the testing becomes a part of the Survey's record of groundwater quality throughout the state.|
Each year about 1,000 Illinois residents turn to the Water Survey's Chemistry and Technology section for help. A homemaker may bring a sample of wash water that has stained the laundry orange. A farmer may bring a sample of livestock water after noting a high death rate among his piglets. A doctor may submit a sample of the tap water to be used by a patient on a low-sodium diet.

Did You Know...Land subsidence (the lowering of the land-surface elevation from changes that take place underground) can be caused by excessive ground-water pumping. In Mexico City, for example, depletion of the aquifer has contributed to significant land subsidence. Over the past 100 years, the central area of the Mexico City Metropolitan Area has fallen by an average of 7.5 meters. Neighborhood children mark their height on well casings to see whether they are growing faster than the ground is sinking.
