I wouldn't bother watching a Tiktok video unless the video maker is an environmental professional. Otherwise this is just the blind leading the blind.
Here's a legal definition of environmental professional used by developers when they do a environmental assessment, from Wikipedia https://en.wikipedia.org/wiki/Phase_I_environmental_site_ass...:
Someone with:
a current Professional Engineer's or Professional Geologist's license or registration from a state or U.S. territory with 3 years equivalent full-time experience;
or
a Baccalaureate or higher degree from an accredited institution of higher education in a discipline of engineering or science and 5 years equivalent full-time experience;
or
have the equivalent of 10 years full-time experience.
