Lake Michigan Mass Balance
Sampling Locations & Techniques
To characterize Lake Michigan over 200 locations (stations) were sampled
during the course of the project. Over 25,000 samples were collected for the Lake Michigan Mass Balance
during the 1994 and 1995 sampling seasons. Samples were collected from three "loading media" including
tributary rivers, air deposition, and open lake. The Mass Balance will produce over 500,000 analytical data points.
The sample collection methods
used in collecting the samples and the
laboratory methods used in analyzing the samples are documented in the
Lake
Michigan Mass Balance Methods Compendium
The environmental data will feed a suite of mathematical
models which will characterize the flow of
pollutants through the ecosystem.
