Eastern White Pine isn't a habitual problem species, so a sound one is usually worth an opinion before it comes out. It gets planted constantly here and the soil does not want it — Purdue documents "white pine decline" specifically as an Indiana clay-soil disorder, where trees look fine for fifteen or twenty years and then quit. Most white pine calls are either that slow unexplained fade or a storm-broken top.
It presents as off-color first — pale to yellow-green next to a healthy neighbor — then progressively shorter needles, shorter annual twig extension, and wrinkled bark on the branches before anything browns. Stress versus dying: a tree that yellows and greens back up in a wet year is stressed, but once annual candle growth is down to a couple of inches, needle retention has dropped to the current year only, and branch bark has shriveled, it is finished.
Structurally the worst of the common Indiana conifers under ice — soft brittle limb wood on long horizontal branches arranged in distinct whorls, so limbs snap a few feet out from the trunk and cascade down through the tree, stripping one whole side. Tops break out regularly as well, and a white pine leaning over a roof or a driveway is the conifer most likely to actually put something through it.
