How Larger Lead Scale Particles are Likely to Move in Service Lines

If lead service lines are present, small lead-containing particles often are observed in drinking water. Because such particles inevitably differ in size, if many small particles are observed, there likely are a few larger ones as well. This work examined the potential movement of such larger particles using a mathematical model for particle transport in pipes. This model suggested that lead scale particles in the size range 20–400-μm, if they …
