Arsenic in Groundwater: How to Detect and Remove It from Tap Water
Arsenic contamination in drinking water is a serious issue in many parts of the U.S. and Canada, particularly for homes using private wells. Long-term exposure to arsenic can cause significant health problems—but the good news is that the right water filtration system can protect your family and business.
⚠️ What Is Arsenic and Where Does It Come From?
Arsenic is a naturally occurring element found in soil and rock. As groundwater flows through these formations, arsenic can dissolve and enter private wells and municipal systems. Industrial waste, mining, and agricultural practices can also contribute to contamination.
🩺 Health Risks of Arsenic in Drinking Water
According to the EPA, even small amounts of arsenic above 10 parts per billion (ppb) can be harmful. Long-term exposure has been linked to:
- Increased risk of cancers (skin, bladder, lung)
- Cardiovascular disease
- Skin discoloration and thickening
- Developmental issues in children
🔬 How to Detect Arsenic in Your Water
Because arsenic is odorless and tasteless, testing is the only way to know if it’s present in your water.
- Lab Tests: Send a sample to a certified lab for the most accurate results.
- DIY Test Kits: Affordable and convenient for initial screening.

✅ Best Water Filtration Systems for Arsenic Removal
Not all filters remove arsenic. These are the most effective technologies:
1. Reverse Osmosis (RO) Systems
RO uses a semi-permeable membrane to remove up to 95–99% of arsenic, along with many other contaminants. Ideal for drinking and cooking water.

3. Combination Systems
For maximum protection, many homeowners and businesses install a whole house filter for broad coverage plus an under-sink RO system for drinking water.
💡 Maintenance Tips
- Test your water every 6–12 months, even after installation.
- Replace RO membranes and filter cartridges on schedule.
- Monitor arsenic-specific media performance with follow-up lab tests.
