“…Methods used for determining concentrations in water and wastewater matrices were first reported in early 2008 in Swedish studies (Brorström-Lundén et al, 2008 ) and subsequent studies (Arbelaez et al, 2015 ; Batchu et al, 2013 ; Batchu et al, 2015 ; Loos et al, 2009 ; Loos et al, 2013 ; Minten et al, 2011 ; Morlock et al, 2011 ; Ordóñez et al, 2012 ; Scheurer et al, 2009 ). There are reviews of LC-MS-MS methods specifically for sweeteners (Lange et al, 2012 ; Lorenzo Ferreira et al, 2018 ; Luo et al, 2019 ). New methods have been developed for SPE (Lakade et al, 2018 ) and for on-line high performance SPE-LC-Ms-MS (Henderson et al, 2020 ).…”

Prevalence of cesspools on tropical islands suggests that high concentrations of enteric bacteria in streams and coastal waters are an indicator of groundwater contamination by human wastewater. But enterococci bacteria may also be from homeothermic animals common to these watersheds or bacteria living in sediments. Sucralose, a manufactured chemical not destroyed in passage through the human gut, cesspools, septic systems, or wastewater treatment facilities, was used to test for the presence of human wastewater in streams on the island of Kauai, Hawaii. Effluent from six municipal wastewater treatment plants showed an average concentration of 39,167 ng/L of sucralose, roughly back-calculated to 9 ng/L per person, enough to present itself in cesspool effluent contaminated waters. Of 24 streams tested, 79% were positive for sucralose at least once in four sets of sampling. All streams tested positive for enterococci bacteria above established standards. Serial testing of the pair of indicators in the same location over time and applying the Multiplication Rule to the independent samples provide a probabilistic certainty level that the water is chronically polluted by human waste. When repeatedly paired with tests for enterococci, sucralose testing is a cost-effective means for assessing human health risk and for developing proper waste management programs that has been underutilized in under-developed tropical and island settings.
