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). Radioactivity is measured because the level of the concentrations is higher as the concentrations which normally occur in water and suspended matter. Another aim is to have an understanding of the current concentrations. The concentration of radioactivity parameters is increased by human activities. The frequency of collecting the samples differs from 2, 4 or 12 times a year. For actual planning:
