Water Seeps or Springs

The following paragraph and three figures were adapted from content presented by Department of Entomology at Michigan State University:

Water seeps most frequently occur at the base of hillsides composed of glacial deposits. Springs arise from water bubbling up from the surface soil that is usually a light-grey colored marl. Water coming from both sources is a constant temperature (between 42 and 55°F), so it will be cold in summer and warm in winter. Seeps and springs can be most easily located during the winter when there is snow cover, as their  warm temperature will create an area of melted snow with running water where the water reaches the soil surface.

Problem. Watch the video below and explain how understanding geology can help aid identifying seeps and valuable groundwater dependent ecosystems. Explain why seeps can "mysteriously" occur in an area where the topography is perfect smooth and flat and shallow aquifer is perfectly homogeneous.
