A dropping water table means a residential pump has to reach deeper and work harder, which shortens its life. In Lake County, that trend is real, not assumed: 1.2 ft per decade over 22 years.
Depth and quality are separate questions
This page answers a depth question, not a quality one. A well in Lake County can be stable in depth and still worth testing for quality, or declining and still test clean, the two are measured separately, and only a direct test settles the second one.
