Description 
Summary

MON*CHEMIE is a part of the Monitoring programme of the National Water Systems (in Dutch : Monitoring Waterstaatkundige Toestand des Lands; MWTL). The primary goal of the MWTL programme is to provide physical, chemical and biological information in relation to long term developments. So the focal point for the monitoring programme is based on trend detection. Another aim is to check the compliance to national and international assessment criteria. The Dutch marine and brackish waters are dived into areas. In field GEOGRAPHIC COVERAGE the area is mentioned. In MON*CHEMIE chemical parameters are determined in surface water, suspended matter, sediment and biota. The starting date mentioned is not necessarily the same for every parameter or location, this can differ from one parameter or location to another. Depending on the parameter and the location most samples are collected on a weekly, monthly or 3 monthly base. The given date is the first year data is available of one or more locations. During the given period more or less locations can be sampled due to changes in the national monitoring programme. Sampling and analysing the samples are carried out by Standard Operating Procedures (SOP's). - Surface Water: Field observations are carried out with sensors and samples are taken to be analysed in the laboratories. The parameters oxygen concentration, oxygen percentage, pH, salinity, suspended matter, dissolved organic carbon, bound organic carbon, total organic carbon, mineral oil are analysed. - Suspend Matter: This part of the programme started in 1989. Samples are taken by centrifuge. The parameters grain size, percentage organic carbon are analysed. – Sediment: The parameters grain size, percentage organic carbon are analysed. Samples are taken by boxcorer. – Biota: No programme running. For actual planning: www.waterplan.nl
