Acid Water - Low pH

Problem – Acid Water, low pH

Symptoms: Blue-green stains on plumbing fixtures, showers, tubs, faucets and drains, and possibly pinhole leaks in copper plumbing.

Causes: Naturally low pH water, high dissolved oxygen, poor plumbing practices (excessive flux, improper de-burring of copper pipes), improper electrical grounding, excessive sand or sediment and/or high velocity flow rates. In a high percentage of the cases, the source of the corrosion may not be determined.

Health Concerns: Though a small amount of copper is required by the human body as an essential nutrient, long-term exposure to elevated levels of copper in drinking water may cause serious health problems. Short periods of exposure to high levels of copper can cause gastrointestinal problems, including nausea and vomiting and longer intervals may cause liver or kidney damage.

Action Level: Over 1.0 mg/l (milligram per liter).
