Objectives coverage of: various determinands with different properties and concentration bands different European regions different dynamics of groundwater (non)periodic time series 03.04.2000
Requirements for quality data (1) Selection of determinands ph-value electric conductivity oxygen nitrate ammonium chloride pesticides chlorinated hydrocarbons ..... 03.04.2000
Requirements for quality data (2) Information required: sampling site identification (unique code) location (GW-body, ...) sampling period (date) determinand specification and units values (numbers, <n, [n]) detection limits and limits of quantification analytical methods level of confidence Formats will be specified and distributed 03.04.2000
Requirements for quality data (3) Provision of values concentration detected and quantified result: numbers concentration is below the limit of quantifacation <n limit of quantifacation =n concentration is not detected [n] detection limit =n 03.04.2000
