Hi. Here are my suggestions towards your essay.


if you want to tell the water which is contaminated, you can try to use "contaminated water rather than water contaminated."


The device to test contaminated water or the device to test the water containing harmful materials.


"like" is not conjunctions.


Prepositional phrase is not able to be the subject of sentence.


where is your subject here?

when you are using the conjunctions, make sure that (the number of conjunctions = the number of sentence +1)


You cannot use this adverbial clause here. try to use Noun Clause.

I hope it can be useful for you.
Goodluck and Keep Spirited.
