ABSTRACT

One hundred crowdsourced samples from municipal water supplies were acquired and tested via ICP-MS for concentrations of Al, Cu, As, Cd, Hg and Pb. Analysis was conducted via ICP-MS using an element-expanded variant of EPA methodology 200.8.[1] Resulting data reveal some samples exceeded current EPA limits for elements in public water. All samples showed zero detectable Hg. The data show that over 90 per cent of municipal water samples collected for this analysis were within EPA standards for toxic elements. This analysis did not test water for fluoride, pesticides or organic
