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 7 contaminant(s) detected in South Island PSD'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 7 contaminants exceeding guidelines (+5 others)
Can reduce the levels of many common contaminants.
Pros
- Lower upfront cost
- Reduced maintenance
Cons
- Does not remove all contaminants
Reverse Osmosis
Filters 7 contaminants exceeding guidelines (+11 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
