NDMA formation from gaskets used in water storage tanks
Elevated concentrations of N‐nitrosodimethylamine (NDMA) were detected in a distribution system during routine monitoring. The high concentrations were localized, and a temporary storage tank was suspected to be the source of the problem. Samples of the gaskets used in the construction of the temporary tank were gathered and subjected to bench‐scale tests. These tests demonstrated that the gaskets, when exposed to system water, did produce NDMA as well as other nitrosamines. Chloramine did not contribute to NDMA or N‐nitrosodi‐n‐butylamine (NDBA) leaching from gasket material.
