Couldn't load pickup availability
Recommended for targeted testing for haloacetic acids (HAA9) in drinking water. Haloacetic acids are a group of disinfection byproducts which form when chlorine and/or chloramine react with naturally occurring organic matter found in certain water sources and distribution lines.
This advanced testing package includes analysis of the five regulated haloacetic acids (HAA5), but also includes four additional, unregulated haloacetic acids. Between 2018 and 2020, the EPA monitored public water systems for these additional four HAAs as part of the Unregulated Contaminant Monitoring Rule (UCMR4).
- Certified lab testing
- Fast turnaround at lab (10 days)

This test kit provides all required materials to properly collect and submit a sample for certified laboratory testing.
