What unique environmental feature near the lunar poles might contain reservoirs of water ice?

Permanently shadowed regions (PSRs)

Permanently shadowed regions (PSRs) near the poles remain in near-perpetual shadow due to the Moon's slight axial tilt, creating extremely cold conditions that allow water ice to be preserved within the lunar soil.
