What this means for you

- Based on the latest EPA data, Cotton Bayou Park 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. Cotton Bayou Park has a D because of its violation record over the past 5 years (10 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.
