What to do next
- Test your own well. County numbers cannot tell you what is in your water. See which tests fit your well.
- Use a lab certified by Pennsylvania. Certified labs in Pennsylvania.
- Compare your results with the EPA limits (arsenic 10 µg/L, nitrate 10 mg/L as N). If a result is above a limit, contact your county or state health department.
- If a result is high: arsenic guide · nitrate guide · bacteria guide · salesperson checklist.
- Test again every year for bacteria and nitrate. Get a yearly reminder.
