There are many types of sampling techniques available to assess the presence of lead in drinking water. Deciding which one to use depends on what the objective is. Different sampling tools can be used to assess lead exposure, evaluate corrosion treatment effectiveness for different plumbing materials, or identify particularly significant lead contributors that can be removed to mitigate the problem.
EPA researchers have identified several sampling protocols to help water utilities assess and mitigate the risk of lead exposure. These techniques fall under two categories–diagnostic water sampling and exposure sampling.
