Hi Jasmine! Great work! Here's an edited version. I put my changes in brackets [ ]. Let me know if you have any questions. -Hunter TEFL Teacher
"Have you ever drunk beer [made] from [wastewater]? I watched a [video about it] on YouTube today. In Germany, people [brew] beer from [wastewater] through four purification steps and in these steps solid waste is removed. [Additionally,] harmful substances [such as chemicals] are turned into solid [forms] for easier removal. At the brewery, they [adjust] the water hardness to make a better beer. The [taste testers] [say] this kind of beer [is as] good [as] regular beer."
