Best Alternatives to Water, Air, Radon & Lead Reports by ZIP | KnowYourExposure in 2025
KnowYourExposure provides free exposure reports for any US ZIP code, covering tap water contaminants like lead and PFAS, radon risk, lead paint, and air quality, all sourced from official EPA and CDC data. While it's a comprehensive tool, you might seek alternatives that offer different features, deeper analysis, or specialized focuses. Here are the best alternatives to KnowYourExposure for water quality and environmental exposure reports.
EWG Tap Water Database
The Environmental Working Group's database is a popular alternative that aggregates water quality data from nearly 50,000 utilities. It highlights contaminants above health guidelines, even if they meet legal limits, and provides filter recommendations. However, it focuses solely on water and lacks radon, lead paint, and air quality data.
EPA Consumer Confidence Reports (CCRs)
These are official annual water quality reports that utilities must provide to customers. They are the most authoritative source for local water data, covering regulated contaminants. However, they can be technical, vary in format, and don't include PFAS or unregulated contaminants in all cases, nor do they cover radon or air quality.
MyTapWater.org
MyTapWater.org offers a user-friendly interface to check water quality by ZIP code, pulling from EPA data. It provides a summary of contaminants and health effects. While it's a good alternative for water, it doesn't include radon, lead paint, or air quality, and lacks trend analysis.
Water Quality Reports by SimpleLab
SimpleLab's Tap Score provides detailed water testing and reports, including contaminants like lead and PFAS. They offer both utility data and at-home testing kits. However, it's primarily a paid service for testing, and the free reports are less comprehensive than KnowYourExposure's multi-exposure approach.
AirNow
For air quality specifically, AirNow is a government-run site that provides real-time air quality data by ZIP code. It's excellent for air quality but doesn't cover water, radon, or lead paint. It's a good complement to water-focused tools.
Radon.com
This site provides radon risk information by state and ZIP code, based on EPA data. It's a specialized alternative for radon, but lacks water, air, and lead paint data. Useful if radon is your primary concern.
Lead Free Kids
This organization focuses on lead paint and water hazards, offering resources and data by location. It's a good alternative for lead-specific information, but doesn't cover other contaminants, radon, or air quality comprehensively.
While KnowYourExposure stands out by combining water, air, radon, and lead paint data in one free report, these alternatives each excel in specific areas. EWG and EPA CCRs are strong for water quality, AirNow for air, Radon.com for radon, and Lead Free Kids for lead. For a holistic view, KnowYourExposure remains unique, but these tools can supplement or specialize your research.
