Full title and description

St NACE Paper 12992-2019 — original NACE International conference paper titled "Several case studies of causes and effects of cuprosolvency" (authors: G.T. Bayer, M.C. Latona, J.R. Datesh, M. Zamanzadeh). The document is the record of a NACE International (International Corrosion Conference Series) technical paper presented in 2019 that examines multiple field case studies of accelerated, generally uniform copper corrosion (cuprosolvency) in plumbing and water systems, and discusses contributing water chemistry and operational factors and mitigation considerations.

Abstract

This paper presents three field case studies illustrating causes and impacts of cuprosolvency — accelerated uniform corrosion of copper or copper‑alloy plumbing materials — including (1) campus-wide copper pipe wall thinning linked to municipal water attributes plus hot-water recirculation, (2) a vacation community experiencing exceedances of the USEPA action level for copper after a transient pH drop, and (3) implications of newly imposed copper discharge limits prompting wastewater authorities to investigate upstream sources. The analysis highlights the role of multiple interacting water quality attributes (pH, alkalinity, disinfectant and film/microbiological effects) and operational factors, and offers practical risk‑assessment and mitigation viewpoints.

Scope

Scope: case-study analysis and practical discussion of cuprosolvency occurrences in potable and wastewater‑related systems, focusing on root causes, water‑quality drivers (chemical and microbiological), operational contributors (e.g., recirculation systems), observed consequences (pipe wall thinning, regulatory exceedances), and approaches for assessment and mitigation in municipal, institutional and small‑community settings. The paper is intended to inform corrosion engineers, water utility professionals and regulators about risk factors and remedial considerations.

Key topics and requirements

• Cuprosolvency: definition, field manifestations and diagnostic indicators.
• Case studies: campus hot‑water recirculation effects; transient pH events and potable water copper exceedances; upstream sources and wastewater discharge compliance issues.
• Water‑quality drivers: pH, alkalinity, disinfectant residuals, soluble complexing constituents, and microbial biofilms.
• Risk assessment: inspection signs, monitoring parameters, and investigative workflows for identifying cuprosolvency.
• Mitigation strategies: water‑chemistry control (pH/alkalinity adjustment, corrosion inhibitors/orthophosphate), operational changes (system flushing, recirculation management), and upstream source control for wastewater limits.

Typical use and users

Typical users: corrosion engineers, water utility technical staff, plumbing engineers, environmental and public‑health regulators, wastewater treatment operators, consultants performing corrosion risk assessments, and researchers studying water‑related corrosion phenomena. The paper is used as a practical reference for diagnosing cuprosolvency events and planning mitigation or monitoring programs.
