Is Magma tap water safe to drink?
Magma's public water is regulated to meet EPA legal limits. The EPA SDWIS record shows 1 contaminant on file, led by Nitrate. Local water is very hard. But meeting legal limits isn't the same as zero-risk. Our Water Score rates it 83/100. See the breakdown below, or pull a free water report to learn what's actually coming out of your tap.
What's really in Magma's water
Nitrate
Violation on record
4 EPA records on file (most recent 2020). Nitrate enters water mainly from fertilizer runoff, septic systems, and animal waste. High levels can interfere with the blood's ability to carry oxygen, a special danger for infants. Long-term low-level exposure has also been linked to elevated cancer risk in some studies.
Water hardness
very hard
Magma's water is very hard. Hardness isn't a health risk, but it drives scale on fixtures and water heaters, shortens appliance life, and leaves skin and hair dry.
EPA violations may be administrative or monitoring/reporting issues rather than measured exceedances of a health limit. A utility appearing on this list does not by itself mean the water is unsafe to drink. Health-based goals (EPA MCLG / WHO) are health targets and are often stricter than the legal limit (the federal MCL). The only way to know what is in your specific home is to test your own water.
