High Iron Well Water on Lawn: Test Both Sources

Well water high in iron. Grass seems better with city water. Harmful? How to know?

Test & Compare

• County Extension or lab: analyze well water for lawn-toxic elements.
• Water Authority: city water analysis.
• Compare—identify divergent factors.

Iron Chemistry

• Low pH (acid) → iron toxic.
• High pH (alkaline) → iron unavailable → chlorosis (yellowing).

Don't guess. Test. Science beats observation.
