vesinäytteeksi

Vesinäytteeksi, also known as aquatic watch or water test, is a portable low-cost water testing kit developed in Finland to determine the cleanliness of drinking water. The kit was created in 2014 by the Finnish Institute for Health and Welfare and several other organizations to assess the quality of wells used for drinking water in rural areas.

The vesinäytteeksi is designed for rural communities without access to laboratory testing facilities. The kit contains a plastic tube with a porous plug that is pushed down into the water sample. As the water rises through the tube, the plug absorbs materials and chemicals from the water, eventually reaching a certain red color. The height of the red liquid is correlated with various parameters such as pH, turbidity, and bacterial presence.

The test results obtained from the vesinäytteeksi can help indicate if the drinking water is of good quality. For turbidity, the presence of red color in the plastic tube is directly related to the amount of particulate matter in the water. pH is indicated by the ratio of the color of the water at different heights. The presence of total bacterial content can be estimated based on how fast the color develops. The vesinäytteeksi test results can help in identifying problems, such as microbial contamination or high levels of chemical compounds, that may be affecting the safety of the water source.

Vesinäytteeksi has been established as a useful tool for identifying potential water quality issues in low-resource settings. Its usability in domestic settings has contributed significantly to promoting the quality of well water across Finland.
