Delaware proposing new drinking water requirements

The discovery of an obscure chemical in a public well near New Castle is prompting Delaware officials to proposing new disclosure requirements.

The change would require utilities to tell customers about the detection of unregulated but potentially toxic drinking water contaminants.

Office of Drinking Water Program Administrator Edward Hallock tells The News Journal that Delaware will require "confidence reports" that tell customers whether chemicals on an annual Environmental Protection Agency list have been detected in water and the concentrations of the substances. Currently, utilities only have to report chemicals for which federal maximums exist, or a smaller set of unregulated contaminants and disinfection byproducts.

The agency will publish details on the proposal and seek public comment on July 1. Regulations would take effect statewide by fall.
