Thank you for sharing your source! I love learning something new through comments so thank you! I will include this on the list as soon as I have some time. I do not see a reason why this website should not be used for scientific posts, especially since it provides data. I have to admit that I am somewhat sceptical of US government websites since I attended a research talk and learned about how influence the EPA seems to be. Anyways, glad I could help, and thank you for your input! Cheers!
