Overview
Legal does not necessarily equal safe.
- Getting a passing grade from the federal government does not mean the water meets the latest health guidelines.
- Legal limits for contaminants in tap water have not been updated in almost 20 years.
- The best way to ensure clean tap water is to keep pollution out of source water in the first place.
AquaPura's analysis shows 14 contaminant(s) detected in Westbury WD's water exceed recommended health guidelines, though they may be within legal limits set by the EPA.

Find a Filter
See which water filtration technologies are effective at reducing the contaminants detected in this utility's water supply.
Carbon Filters
Filters 9 contaminants exceeding guidelines (+16 others)
Can reduce the levels of many common contaminants.
Pros
- Lower upfront cost
- Reduced maintenance
Cons
- Does not remove all contaminants
Reverse Osmosis
Filters 14 contaminants exceeding guidelines (+20 others)
Can reduce the levels of many common contaminants.
Pros
- Most effective
Cons
- Higher upfront cost
- Requires more maintenance
- Wastes water
Other Considerations
Ion Exchange
PROS: Softens hard water, Reduces some contaminants
CONS: Doesn't remove all contaminants
Whole-House Filters
PROS: Useful for reducing radiologicals and TCE
CONS: Expensive to install and maintain, Risk of bacterial contamination
