Weather data:
- are collected by automatic weather stations and the results are transferred automatically to a central unit, frequently also available immediately to the public via Internet.

Pollution data:
- are normally collected manually by field visits and the samples are then brought to laboratories for analysis.

Billions of dollars are spent annually for sample collection and laboratory analyses.
Can this be done automatically – like in meteorology?

We, Øyvind Mikkelsen and Knut Schrøder (Professor) work at Norwegian University of Science and Technology (NTNU) within the field of Analytical Chemistry. Our research is focused on the development of methods for environmental monitoring. In particular we are dealing with methods that open for remote and automatic monitoring without the need for frequent attendance.

Remote monitoring of heavy metals like copper, cadmium, mercury etc. is of special importance. For that reason a very extensive research has been carried out internationally to develop suitable methods as no acceptable methods were available.

However, about seven years ago we invented ideas that possibly could be applied for remote and automatic monitoring of important heavy metals, consequently we started an extensive method development process. We have succeeded to obtain very satisfactory results over a long testing period, being quality assured by frequent comparison with laboratory methods. We have documented our results in a great number of international publications and also presented method and results on several scientific conferences and specialist groups. Automatically remote measuring stations are established with convincing results. Here we measure drinking water quality (with respect to heavy metals) in drinking water, effluents, from a disclosed copper mine, scrubbing water from an incineration plant, and control process water and effluent water from metallurgical industry. For practical reasons, most of our activities are set up close to Trondheim, but measuring stations in Beijing, Kina is under construction in collaboration with Chinese environmental authorities, and also in France, Svalbard, Iceland and on the Swedish side of the border near Trondheim. Contacts in Finland will also be established. Up to now, all our stations are established as a part of our research in methodology and stability, but we are now commercializing this after obtaining good measuring references through our recently established company SensAqua AS (Remote Sensing in Aquatic Systems,, in collaboration with Innovation Norway and Innovation Mid-Norway.

SensAqua AS is now producing and marketing the new system for automatic and remote monitoring heavy metals in water, effluents and industrial processes. Very extensive development and research is carried out by the collaborating research group at NTNU, not only for academic and educational purposes, but primarily further to improve the measuring system for environmental monitoring.
