PARAMETER EVALUATION

Utilized the software program DUMPStat to screen data from the year 2000 to present by parameter group

§

Chlorinated Herbicides

§

Organophosphorus Pesticides

§

Polynuclear Aromatic Hydrocarbons (PAH’s)

§

Chlorinated Hydrocarbons

§

Metals

Created a report of all wells and all dates by each analyte from within the parameter group for export into Excel for further evaluation.
