Absolutely. There are a number of other things that are often looked at when we’re talking about waste disposal, COD and BOD are really big ones. To generalize, things that are pH neutral tend to have a lot of solvents and to maintain being pH neutral that means that you’re going to have high BOD and COD levels compared to a balanced cleaner. So, pH is certainly one thing that is looked at, COD and BOD are another that are often looked at very quickly as well.
