What this means for you
- Is it safe to drink right now?
- Based on the latest EPA data, Cwm Water Authority has no unresolved health-based violations from the past year. Water that meets federal standards is generally considered safe to drink for most healthy people.
- Should I use a filter?
- It's worth considering. Cwm Water Authority has a D because of its violation record over the past 5 years (11 health-based), even though nothing is flagged as unresolved in the last year. A filter matched to the contaminants in its violation history is a reasonable precaution.
- What kind of filter?
