The data collected must be Representative (2). Reproducible. The data must be reproducible by others following the same sampling and lytical protocols (3). Defensible. The data must have a known degree of accuracy and precision (4). Useful. The data can be used to meet the objectives of the monitoring plan

If the physical, chemical, and/or biological integrity of the samples is not maintained during interim periods between sample collection and sample analysis, a carefully performed sampling program will become worthless Prompt analysis is undoubtedly the most positive assurance against error due to sample deterioration Probable errors due to deterioration of the sample should be noted in reporting analytical data

Methods ofanalysis The analyses used to characterize wastewater vary from precise quantitative chemical determinations to the more qualitative biological and physical determinations The quantitative methods of analysis are either gravimetric volumetric, or physicochemical Turbidimetry, colorimetry, potentiometry, polarography, adsorption spectrometry, fluorometry, and nuclear radiation are representative of the physicochemical analyses
