Health Effects of Copper

  • Nausea, vomiting, and diarrhea (short-term, high levels)
  • Liver and kidney damage (long-term)
  • Particularly dangerous for people with Wilson's disease
  • Infants are more sensitive than adults

Health risk severity: Moderate. Governed by the Lead and Copper Rule.

How Copper Gets Into Drinking Water

  • Corrosion of copper household plumbing
  • Acidic (low pH) water accelerates copper leaching
  • New copper pipes leach more than aged ones
  • Mining and industrial discharge (rare for tap water)

What to Do About Copper in Anchorage Water

  1. Run water for 30-60 seconds before use (flushes stagnant water)
  2. Install an NSF 53 or NSF 58 certified filter
  3. If pH is low, consider a whole-home acid neutralizer
  4. Test first-draw morning water to check actual copper levels

Look for filters certified under NSF 53 for copper removal.
