Whether a new home can legally get its own water here — the sub-state groundwater regime, from Mississippi’s water agency.
The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.
Even amid severe Delta aquifer decline there is NO moratorium or closure on new domestic wells; a single-household well (or <6-inch casing) is exempt regardless of volume. Non-domestic/irrigation wells need an MDEQ permit (administered in the Delta via YMD).
Limit: single-household wells exempt from the withdrawal permit

Non-domestic wells need an MDEQ/YMD permit; domestic household wells are exempt. No formal closure. Core decline is the central/lower Delta (Bolivar, Sunflower, Leflore, Washington, Humphreys, Quitman, Tallahatchie).
