4.2. Decision Making in Monitoring

If I want to find out what is there in environment, it is a huge task right? I can have potentially even from this list itself, potentially I can have a large number of, I can have I can I can go across this entire class of compounds, I have to do some way of even to find out what is there, it is very hard, the analysis of any of these compounds to find out. If somebody comes and asks a question, I will give you a water sample, please tell me what is there in the water sample. Any of these could be there in the water sample, technically, right, I cannot so can I have a problem because I have I have to spend a lot of money and energy and time in order to find out what else is there, all of this is there, and then we have also this entire range of compounds here.

Monitoring the environment for chemicals is a complex task. There are many different substances present in the environment, and identifying all of them can require significant resources. For instance, if someone gives you a water sample and asks you to identify the chemicals in it, you could find numerous compounds. Testing can be costly and time-consuming, making it difficult to determine what you should look for.

Imagine you own a small bakery. If a customer complained about the taste or quality of your pastries, you'd have to test each ingredient you use. If you have 50 different ingredients, checking them all would take a lot of time and money. You might focus first on the most popular ingredients that are more commonly associated with taste issues.

So is there a way in which I can, then it becomes matter of engineering decision making that I have to spend my money and resources and time where I can guess whether one of, which of this is likely to be there. I also need a ranking. I need to be able to prioritize whether something is there or not. If I am looking for a particular compound and if that’s not likelihood of that not being there is high, then I don’t have to spend my time looking for that. So, I must have some rational reason why I am looking for a particular compound.

To efficiently monitor chemicals in the environment, it is crucial to prioritize which substances to test for based on their likelihood of being present. This process involves engineering decision-making where environmental scientists must allocate limited resources wisely. Rather than testing every possible chemical, they focus on those that are most likely to be found and that pose a greater risk to health or the environment.

Consider a doctor trying to diagnose an illness. If a patient shows symptoms of a common cold, the doctor may prioritize tests for the flu or strep throat first instead of running tests for rare diseases. The doctor uses their knowledge of likelihood and impact to make an informed decision about which tests to perform.

This will link into our next topic in the next section of monitoring and analysis, I have to make decisions of which one to monitor, which one to measure, because it costs money to do all of these things. These are all linked back to that if I have infinite resources, I have 100 people working on one sample, I can do everything in the world. Unfortunately, we are not in that scenario. We have to make decisions which we in which we rank things, and then the highest, most this thing gets the priority.

Monitoring for various chemicals involves financial considerations. Each test costs money and requires resources, meaning scientists must carefully choose what to analyze. Unlike in an ideal world where resources are limitless, environmental monitoring often operates under budget constraints. This requires strategic decisions on which chemicals warrant attention based on their potential impact.

Think about budgeting for a party. If you have a limited amount of money, you can't buy everything you want. You might decide to allocate more money to food and drinks—because these are vital for a good party—while spending less on decorations, which are nice but not essential. In a similar way, scientists must decide what is critical to monitor in environmental testing.
