Purpose

Measuring long-term water quality is necessary for studying the effects of changing land uses and climate variability and to show improvements in water quality with the adoption of conservation practices. The goal of this monitoring is to support long-term intensive research on the impacts of agriculture on water quality in the northeastern United States.

Use limitation

Various analytical techniques have been employed over the 24 year data period, reflecting changes in technology (e.g., increases in sensitivity, changing to an automated methodology), reduction of hazardous material generation, or the needs of researchers working at the site. Blank and replicate samples were run with each batch of samples in the lab as a matter of course, and at the time of switching methods, duplicates of all samples were analyzed to ensure data continuity within the laboratory; unfortunately, those data were not retained. An examination of the data, however, reveals no sudden increase or decrease in concentration reported at the times of switching methods, one indication that the data is internally consistent.
