Since water is the most important necessity of life and every living being needs water to survive, maintenance of its quality is really important for human health. Therefore, frequent testing of drinking water is crucial to the safety and health of humans.
The collection of water samples needs to be done properly in order to get accurate results. Although different labs have different SOPs, there aresome basic principles of water sampling that are followed everywhere.
Sampling and preservation techniques, holding times and even the types of bottles in which water is collected all play key roles in getting the accurate results.
When a cold wave hits, water-pipe damage is never too far behind. In freezing weather, it is not the pipe that freezes but the water inside the pipe, That ice will also expand within the pipe. This conversion into ice and subsequent expansion can cause pipe joints to break, or for the pipe wall to be damaged. If unchecked, the resulting leaks can damage carpeting, floors, fiberglass insulation, and drywall. The major sources of such leaks are found to be in copper pipes which supply water toplumbing fixtures, or to baseboard radiators. Here are the most common causes of bursting pipes in cold weather:

A major reason for this is lack of awareness. If your drinking water appears to be clear, That does not necessarily mean that it is safe to drink. Many deaths are caused by water borne diseases, and contaminated water is one of the major causes. Therefore, water testing is a must to avoid the health hazards of polluted water.
You never know for sure whether a material contains asbestos until you get it tested. Gathering and storing an asbestos sample is not an easy task, therefore we have listed the complete asbestos sampling procedure so that you know how it is done:
Preparation before sampling
- Make sure that no one is around while you take the samples.
- Turn off all fans, air conditioners, or heaters to prevent asbestos fibers from spreading in the air.
- If the sampling is done outdoors, then perform the procedure on a non-windy day.
- Be very cautious, and don’t disturb the material more than necessary to remove a small specimen because you might disturb the asbestos in it (if any).
- Arrange these things before collecting the material for sampling:
