Do you work in a water treatment plant?
Are the pictures yours? You should credit them somewhere, either under each picture or at the end of the article!
The same goes for the text. Even if you work in a water treatment plant, Steemit and science in general is a place where you need to provide proof for what you are saying to by crediting or at least pointing out to another source of information,so you are providing an objective point of view.

If you are on discord on SteemSTEM and you want to better yourself, send me a message and I can give you a quick list of tips and follow you for a bit, until you get the hang of it and start growing :P
