Is it safe to drink from garden hose water after running it a minute?
Based on 2 peer-reviewed studieshome
Verdict: Use Caution
Better than the first flush, but standard hoses still leach with use.
What's actually in it
Running a garden hose for a minute flushes the hot stagnant water that has the highest plasticizer and lead load. Fresh incoming water still passes through the hose walls, picking up smaller amounts of chemicals.
What the research says
A 2025 study linked phthalates to slower infant neurodevelopment. A 2025 study found lead in brass fittings.
Flush the hose for a minute. For drinking or filling a kiddie pool, use a drinking-water-safe hose marked "lead-free, phthalate-free."
