Water Testing Services

Service Details:

Sometimes we face problems with usable water. Water appears cloudy or coloured, plumbing starts corroding faster, water has foul smell or tastes odd, clothes washing starts giving stains or the soap does not foam much. It is the time we must get water checked. More importantly, when the health related problems, especially gastrointestinal illness, are visible, we need to rush water for testing.

The quality of dialysis fluids is too often a neglected problem at many renal healthcare centers. Every week, haemodialysis patients are exposed to about 400 lit water for the production of dialysis fluids which come into direct contact with the bloodstream. It is, therefore, clearly vital to monitor the chemical and microbiological purity of dialysis water. Not only the final dialysis water quality but also the quality of water at various stages of purification system needs to be monitored. As there is always a risk of chemical contamination due to primary pollution of municipal water, whereas the problem of microbiological contamination lies across the stages of entire treatment, distribution and point of use.

All forms of life rely on an active hydrosphere and human beings are particularly interested in the fresh water hydrosphere as the rivers are of immense importance geologically, biologically, historically and culturally. Water quality monitoring is one of the first steps required in the rational development and management of water resources to maintain their wholesomeness and pristine.
In the field of water quality management, there has been a steady evolution in procedures for designing system for the designated best use. The monitoring comprises all activities to obtain information, including water characteristics, with respect to the water system.
It is a fact that the natural water courses are exposed to variety of pollution at various degrees; hence it becomes essential to measure the suspected contaminants for their management.

Pool water sanitation is utterly important to ensure healthy conditions in swimming pools or similar recreational water bodies. Proper sanitation is needed to maintain the visual clarity of water and to prevent the transmission of infectious waterborne diseases. Contaminants added up swimmers can influence the pool water management.

Typical contaminants that decrease the water quality include microorganisms from infected users and body oils including sweat, cosmetics, suntan lotion, urine, saliva and fecal matter.

Additionally, the complex reactions between disinfectants and water contaminants can produce a mixture of chloramines and other byproducts. Pathogenic contaminants, i.e. microbes pose greatest hazard to the users leading to recreational water illnesses. Typical pathogens are viruses, bacteria, protozoa and fungi. Diarrhea, Cryptosporidiosis and Giardiasis are the most commonly reported illness associated with pathogenic contaminants, while ear, skin rashes and respiratory infections are also common.

Key to a well maintained pool is timely and thorough testing of feed and pool water.

It is recommended that water from each source shall be got tested before the commencement of construction work and with appropriate frequency thereafter till the completion of the work. Water used for mixing and curing of concrete needs to be clean and free from detrimental contaminants of alkalis, acids, oils, salts, organic materials, vegetative growth or other substance that may be deleterious to bricks, stone, concrete or steel. Generally potable water is considered satisfactory for mixing. Here are some parameters that are required to be tested as per the standard.
