Rising population and industrialization has provoked massive impurity of water resources therefore led to water shortage issues. The impacts of water deficiencies and water pollution have been felt in both industrialized and developing countries and it will be essential to exceed international and political boundaries to meet the world’s water needs in a ecological manner that will safeguard and preserve the resource. In the last few spans, national and international organizations from both the public and private sectors have joined their hands to tackle global issues related to water.
Water testing is based on the inspection of the physical, chemical and bacteriological parameters and requires modified tool and trained staff. Water testing comprises measurements of physical characteristics (such as pH, temperature and conductivity), chemical parameters (such as oxygen, alkalinity, nitrogen and phosphorus compounds) and abundance of certain biological taxa. Testing and analysis could also include assays of biological activity such as alkaline phosphatase, tests for toxins and direct measurements of pollutants such as heavy metals or hydrocarbons.
In daily use there are more than 50,000 known and emerging chemicals that might be existing in various water resources, including for drinking water production. As the online water testing become easier with the development of technology the popularity of the process is spreading across the world. Currently, single instrument for water testing is not more in practice, people are moving towards new technologies to measure each parameter. Innovation of improved testing devices revolving around product simplicity, and ease of use, will help spur adoption among end-users. Online water technology comprises of various advantages such as new plug-and-play devices feature sensor technologies, spontaneous programming, on-board networking, and hassle-free integral maintenance. pH meters are also observing significant advances at the functional, material as well as component levels.
Hence, online monitors are the appropriate and fastest way to detect the excess of pollutants established by the official water quality regulations. This requires sensitive sensors as standards are often close to the limits of detection, e.g. the EU pesticide standard of 0.1 μg/L.
Overall, the development in water testing products is playing a vital role in developing water testing and analysis market.
