* This work shall be performed by measuring ammonium, converting organic nitrogen to ammonium by digestion and then re-measuring for total ammonium using a colorimetric method [Standards Methods 4500-NorgB, C (APHA etal., 1998)]. Other equivalent or accepted methods can be used to perform this work.

**This work shall be performed by measuring persulfate digestion, which converts all forms of N to nitrate, followed by colorimetric method [Standards Methods 4500-NorgB, C (APHA etal., 1998)] or via analysis of total Kjeldahl nitrogen (TKN, see previous description) with addition of nitrite and nitrate. Other equivalent or accepted methods can be used to perform this work.

***This work shall be performed by converting phosphorus compounds to orthophosphate via digestion, followed by colorimetric methods. Digestive methods are outlined in Standard Methods 4500-P B (Alpha et al., 1998). Other equivalent or accepted can be used to perform this work.
