Lead in synthetic and municipal drinking water varies by field versus laboratory analysis.

ABSTRACT: Water lead measurements by two field analyzers, relying on anodic stripping voltammetry (ASV) and fluorescence spectroscopy, were compared to reference laboratory measurements by inductively coupled plasma mass spectrometry (ICP-MS) in progressively complex datasets (phases A, B, C), to assess field analyzer performance. Under controlled laboratory quantitative tests of dissolved lead within the field analysis range and optimal temperature range, lead recoveries by ASV ranged within 85-106 % of reference laboratory values (corresponding linear model: y = 0.96x, r² = 0.99), compared to lower lead recoveries of 60-80 % by fluorescence (y = 0.69x, r² = 0.99) in phase A. Field analyzer performance deteriorated in three opportunistic laboratory datasets compiled for phase
