Repairing Salt-Damaged Soil from Pool Overflow

Lawn killed by saltwater pool overflow—bare ground, nothing growing. Homeowner wants to sod but fears failure.

Assessment First

Conduct a standard soil test. If salinity is moderate, repair in place:

• Apply 1" quality compost, till in, water frequently before replanting
• Compost's high cation exchange capacity counters salt damage

Severe Damage

If salt concentration is high, excavate 6+ inches (to depth of salt intrusion), replace with clean soil, then seed/sod.

Buffer Strategy

Topdress entire lawn with compost (⅜" annually, ¾" heavily around pool). One cubic yard per 1,000 sq ft for standard rate; two for heavy. This builds long-term salt resilience.

Pool chemicals may add additional salts beyond sodium chloride. Test specifically for soluble salts.
