Tap Water Testing

The source of tap water is surface water and groundwater.  When there are excessive substances in people's drinking water, it will cause various physical diseases or spread diseases, thus threatening people's survival. Through the form of tap water testing, the harmful substances in the tap water can be detected to a certain extent, and the relevant personnel look for the source of pollution according to the harmful substances to ensure the safety and reliability of drinking water.

Testing Services

BOC Sciences has professional water quality analysis experts who can provide tap water testing services to our customers. Tap water testing includes both routine and diversified testing, with the aim of analyzing all aspects of the substances contained in tap water to see if they meet the standards and regulations.

• Conventional tap water testing

When water pollution is found, real-time water quality testing is required to ensure that the quality of water is qualified and meets the drinking requirements before it can be put into normal use. Through the tap water quality testing, can get all the data of water quality, analysis of the pollutants and exceed the value, help the relevant staff to develop a suitable tap water treatment program.

• Diversified tap water testing

Normally, water quality testing in water supply companies can be divided into several different levels.

1. Online detection

Online detection including turbidity, raw water, chroma, pH value, chlorine, etc.

2. Routine detection

Routine detection is for pollution indicators, microbial indicators, etc., to provide guidance for production, after detection of oxygen level, fecal macroflora, total coliform, nitrite, etc. Total coliform, nitrite nitrogen and ammonia nitrogen were the main contents

3. Regular testing

The third level of testing is for regular testing of raw water, pipe network water and factory water of water supply enterprises. On the basis of routine detection, the three-level detection items are more detailed and accurate. Tap water testing should be strictly strengthened to improve the safety of tap water quality.

BOC Sciences can provide you with a customized tap water test service, if the above test content does not meet your needs, please contact our staff.

Measures to Improve the Quality of Tap Water Testing

Standard substance monitoring

The usual practice is the laboratory with the appropriate certified standard substances or internal standard samples as test samples, in the form of code samples, and sample testing in the same process and method at the same time, test results reported to the relevant quality control personnel after the completion of the test, but also by the testers themselves to arrange for the insertion of standard substances in the sample testing at the same time to verify the accuracy of the test results.

Selecting the right analytical method

The accuracy of various analytical methods is not the same, when choosing the analytical method, choose the best analytical method. For high content components in water samples, generally choose chemical analysis method, to obtain more accurate and satisfactory results; and for trace or trace components in water samples, we should choose the instrumental analysis method, can quickly and accurately obtain the test results.

Calibration instruments

Water quality testing process, the use of analytical instruments, glass measures, such as analytical balance, atomic absorption spectrophotometer, ultraviolet spectrophotometer, pipette, burette, volumetric flask, etc., should be qualified by the metrological department for calibration, calibration and qualified before use.
