The researchers are just finding out the perfect solution for the public so as to overcome their obstacles. The most recent is the “coffee-ring effect” that is formed around the spilled liquid. This darkened area circling the perimeter of the spin helps the researchers identify the mineral contents present in the tap water at a quicker pace.

The identification of mineral contents of water is very important to know the presence of contents and properties of the tap water belonging to a specific region. After the evaporation of water, the residues left behind look similar to that of fingerprints that can help study the water. According to the researcher Rebecca Lahr from the Michigan State University, the detailed analysis of the mineral contents of the tap water that too at a feasible price is what they had planned for and it just seems to have occurred.

The coffee-ring effect shown by the minerals present in the tap water are intricate and also consists of a specific pattern. The identification of the specific constituent producing the coffee ring is not possible; however, the mineral traces can help study the water contents. The conventional methods used to test the tap water is not only time consuming but also expensive and this new technique can prove to be cost effective, quick, and can help test the water anywhere that too anytime. The patterns formed can help identify the residues and significant contents of the drinking water.

In an experiment, the researchers took samples from different sources and dried them on aluminum strips. Then the mobile phone camera with the jeweler’s loupe was used to magnify and capture pictures of the formed residue. With the help of the patterns formed, the researchers could identify the presence of certain metals or solids and also measure the alkalinity or water hardness.

The patterns helped recognize the quality of water used in the various regions and use the distinctive markers’ rate its properties and utilization. The technique can help the people trace the contents of their own water in an effective manner by using this simple method. The researchers are looking forward to develop a database that contains the specific residue patterns formed by the tap water under room temperature and help the people detect the anomalies affecting the water quality easily.

Though the project is still in the infancy state, let us hope it commercializes soon for the benefit of the people in the coming months.
