Why Multilevels?

Contaminant plumes usually display considerable variations in concentration over small vertical distances. Conventional monitoring wells can be ineffective in defining plumes because long well screens mix water samples of varying concentrations. Worse yet, ambient flow of groundwater in conventional monitoring wells can spread contamination within the aquifer.

Multilevel systems provide groundwater samples from multiple depth-discrete levels (ports) optimizing the amount of information obtained in a single monitoring hole. A transect of Multilevel Systems across a site more clearly identifies the area of maximum concentration.
