Kalamazoo County, Michigan, has just announced that its drinking water supply is contaminated and unhealthy for drinking or cooking. Officials have declared a state of emergency.
You may recall: Three years ago, the city of Flint, Michigan, discovered lead contamination in its drinking water supply.
As a consequence, Michigan ordered statewide testing. The water systems of Parchment and Cooper Township were found to have per- and polyfluoroalkyl (PFAS) levels as high as 1,410 parts per trillion. The recommended limit is 70 ppt.
Michigan has found a total of 34 confirmed PFAS sites around the state.
I have blogged about PFASs before. These are man-made chemicals found in household products ranging from cookware to pizza boxes. PFASs have been shown to cause reproductive and developmental, liver and kidney, and immunological effects in laboratory animals. PFASs do not break down and can accumulate over time. Boiling your drinking water will not get rid of them.
Agilent is a leading provider of solutions to ensure the safety and quality of drinking water. Agilent has developed a method for the analysis of PFASs in drinking water using the Agilent Ultivo Triple Quadrupole LC/MS.
