BearLakeNews suggests all Village residents receive hand delivered notification of the need to continue monitoring and line flushing during construction work. The number of lead (i.e Pb the metal – not ‘lead’ pronounced ‘lead’) service lines and/or connective brass fittings and fixtures is unknown within the Village water system and older village properties. Confusion arises when the term for the line entering a property from the water main in the street is often referred to as the ‘lead line’, meaning the line leading to the property, not necessarily made of lead the metal.
On July 30, 2018, WERF(Water Environment Research Foundation) published report #4854 “Evaluation of Flushing to Reduce Lead Levels”
On August 9, 2018, WERF hosted a web seminar to detail the research findings.

This research paper looked specifically at the long term release of lead and copper from a multitude of sources, including: older fittings inside a home without a lead service line; disturbance during replacement or construction.
The report strongly recommends that all faucets in a house be flushed as particles can accumulate in pipe bends and aerator filters.
