Tool T05 · Breach Check

How protected is your neighborhood?

Pick a Shelby County neighborhood. See whether the clay shield above the Memphis Sand Aquifer is thick, thin, or broken underneath it. Distance to the nearest known breach is the key number.

How protection is assessed

Distance to breach — less than 1 km is exposed; 1–3 km is weak; 3–5 km is moderate; 5+ km is strong.
On recharge zone? — If yes, there's no clay shield at all. Surface activities directly threaten the aquifer.
Nearby contamination — A thin shield matters more if there's a known contamination source upstream hydraulically.
