Water Sampling 101

If you have never worked in a lab or a water treatment facility, you are likely not aware of the complexities of water sample analysis. There are a lot of steps to follow to ensure that the water analysis results are accurate.

First, you should assess your required outcome. If you must comply with municipal by-laws – which can be quite complex – it is best to develop a sampling and analysis plan that will help you produce an accurate water sample. Once the plan is developed, you are ready to work with your accredited water analysis laboratory to determine its need for successful analysis, including the volume of the samples, the type of bottles to be used, and any preservation needs of the samples.

Next, you need to establish your sample locations and procedures, and determine if there are any other important factors that could affect the analysis. Your sample location is important: it should properly represent your drinking water source. You may require a sample of raw water (before treatment) or treated water, or you may need to take samples from multiple locations. Timing is important, too. If you are experiencing low water quality in the height of the summer, you don’t want to take samples in November when water levels have changed.

Note that some samples will have short holding times and will require some pre-planning to ensure timely delivery to the lab.
