Threats to water qualityReferences and more details

Ensuring that our water is clean and safe to drink is a large priority in most of the world. Nevertheless, the method used to monitor the quality of our drinking water is far from optimal and several countries experience unsatisfactory water quality. Every day, water quality is monitored manually, all over the world. Samples are manually collected and sent to a laboratory for analysis, a process that is both inefficient and expensive.

20 years ago, the EU established a list of parameters that must be monitored in the drinking water. Because the list is not exhaustive, some pesticides, chemical compounds, and other toxins are currently not being identified when water quality is measured, and they will continue to go undetected until they cause a part of the population to fall ill. It is of the utmost importance for public health to find a method of monitoring that is not dependent on a list of parameters, but rather reacts to a broad spectrum of contaminants.


As the use of pesticides and medications in the farming industry is increasing, so is the need to find methods of detecting a broader spectrum of contaminants in drinking water.

New and improved pesticides for agricultural use are continuously developed and improved, and may evade current water testing regimes. When spraying the crops, pesticides are absorbed into the ground and transfered to the ground water.


The quantity of wastewater and sewage water from industry, humans and animals is rapidly increasing due to population growth, urbanization and economic development. 80% of global wastewater flows back into the ecosystem without any form of treatment, causing environmental problems from contamination as well as contaminating potential drinking water resources. Medications used by people and livestock can also eventually find their way into the ground water and are usually hard to detect.

Water terrorism

The possibility of water terrorism is present, and the distribution system is at risk. As long as there is a delay in water monitoring test results, there will always be openings for people who want to deliberately contaminate drinking water.

The list of toxins tested in drinking water is also publicly available in most countries, meaning that there is a high risk that deliberate contamination of drinking water will occur with unmonitored toxins.

Climate change

Climate changes such as severe draughts, storms, floods and other high impact weather events are a threat to both water quantity and quality. These changes have a large impact on the availability of clean water, water quality and the pathogen dynamics, causing new and unexpected contamination patterns in the water.

Our solutionMore about the technology

BiWAS provides real-time broad spectrum detection of biological and chemical hazards. This is the first lab-on-a-chip device that can continuously monitor traces of acute toxicants, toxins and waterborne pathogens present in water. The BiWAS solution is small enough to be placed at different points in any distribution network, giving the possibility to trace contamination downstream of the contamination entrance point.
