Frequently Asked Questions
Is there total trihalomethanes (tthm) in Nebraska water?
Nebraska has 2,779 public water systems. 1880 have recorded total trihalomethanes (tthm) violations based on EPA SDWIS data. If you are on a private well, your water is not covered by these regulations and should be tested independently.
How can I check my Nebraska water for total trihalomethanes (tthm)?
Search for your water system using the WaterCheck system lookup, or contact your utility and request a copy of your Consumer Confidence Report (CCR). The CCR is published annually and lists all detected contaminants, their levels, and the EPA MCLs. For private wells, contact a state-certified lab for independent testing.

How to Filter Total Trihalomethanes (TTHM)
- +Activated carbon filters reduce TTHMs effectively
- +Reverse osmosis also removes TTHMs
- +Letting water sit uncovered may reduce some volatile TTHMs
