LetzTest is based on the conviction that “safe drinking water”, as mentioned in the UN Sustainable Development Goals (SDGs), can only be guaranteed when there is a local capacity to perform professional water quality testing for national priority parameters. Even though some developing countries have started to establish their own national water quality testing laboratories, the number, quality and capacity of these facilities is usually very low and very far from meeting the needs. Especially in more remote areas, people are hardly ever connected to any sort of water quality monitoring.

Running a water quality testing laboratory in a setting that has a lack of infrastructure is a challenge, some major difficulties  are:

-  Making the right choice of instrumentation and consumables

-  No local suppliers and poor customer services from foreign suppliers

-  High cost of laboratory instrumentation and consumables

-  Higher costs due to transportation and custom charges for laboratory equipment

-  Limited financial capacities

-  Complex purchasing and inventory management

-  Lack of qualified workforce resources

-  Bad infrastructure and unfavorable climatic condition

-  Tendency to overdo things (excessive micromanagement)

-  Missing quality management systems

-  Poor communication systems

In some cases, NGOs try to close the gap by using portable field kits from overseas to improve the situation. However, we doubt that these field kits are a good solution because they depend very much on costly consumables which are not available on the ground and it appears that there is no continuity in this approach. Developing local water testing laboratories and qualified workforce resources, in combination with suitable equipment, seems to be a far more sustainable Approach.

"Developing successful water laboratories in areas of limited infrastructure has become a professional passion. After a B. Sc. in Water Science and a M. Sc. in Management and Technologies of Water and Wastewater my main interest was to find out the key factors of success to run a successful water testing laboratory in a lower income country. The most valuable experience for me was the practical experience as technical laboratory manager in Cambodia from 2009 - 2011. Since then I have been working within this topic for different organizations in Asia and Africa and have foundet the Organisation LetzTest in 2018."

" Having been introduced to water sanitation during my Clinical officers course in Fort Portal Uganda, I found out that Water to the body is life and keeping it safe for consumption is saving life. This is the reason I pursued a B. Sc. as well as a M. Sc.  both in Water sciences. During my studies I gained a lot of experience in several water laboratories. I am currently working for Letz-Test where I guide customers on our products and at the university of Rhein-Waal where I share my knowledge with students as a scientific staff. "

Laurane Detolle M. Sc.


"Short before joining the LetzTest adventure, I coordinated within an association of public interest a groundwater quality survey in the Upper Rhin region. This enriching work followed up the development of a master plan for wastewater in the four main coastal cities in Benin including the economic and administrative main cities as well as an experience within a water analysis laboratory in Germany. My graduations in water and civil engineering have always been practical and as most of possible international oriented."
