The Landscape Development Intensity index (LDI) is an estimate of how much humans have altered an area of interest around a waterbody. Various land use types (low density residential, row crops, industrial, natural) are assigned coefficients of land use intensity based on estimates of the amount of human energy that is put into those land use types.
In 1992, the U.S. Environmental Protection Agency (EPA) defined ecoregions and subregion as areas "within which there is an apparent homogeneity in a combination of geographic characteristics that are likely to be associated with resource quality, quantity and type of stresses." Regionalization was performed as a collaboration among DEP, water management districts and the U.S. EPA Environmental Research Laboratory in Corvallis, Oregon.

Bacteriological Analyses
The Bench Biology workgroup conducts bacteriological tests for enterococci, Escherichia coli, fecal coliforms and total coliforms. These bacteria are commonly found in the intestinal tract of warm-blooded animals. Their presence in water samples can indicate the potential presence of fecal pollution and enteric pathogens.
