What Is Tebuconazole?

Tebuconazole is a triazole fungicide widely used in agriculture to control fungal diseases on cereal crops, grapes, and other produce. It enters water through agricultural runoff and spray drift. No EPA maximum contaminant level has been established. Chronic exposure is associated with liver damage, and the compound has potential endocrine-disrupting properties that may affect hormone function and reproductive health.

How to Reduce Tebuconazole in Your Water

  1. 1Install a point-of-use activated carbon block filter certified to NSF/ANSI Standard 53 for pesticide and fungicide reduction; activated carbon effectively adsorbs triazole compounds.
  2. 2A reverse osmosis system certified to NSF/ANSI Standard 58 provides additional removal of tebuconazole and related fungicide residues.
  3. 3For well water near agricultural areas, use a granular activated carbon system at the point of entry for whole-house treatment.
  4. 4Test water through a certified laboratory if located near cereal or grape farming operations, and maintain filter media on the recommended replacement schedule.

Who Is Most Vulnerable to Tebuconazole?

The safe level of tebuconazole varies significantly depending on who is drinking the water. CheckYourTap calculates adjusted safe levels for each member of your household:

Infants (under 1 year)
