Table 2. Description of fizz rating and
amounts and strengths of HCl acid added to an overburden sample
based on a fizz rating using 25% HCl acid (Noll et al., 1988;
Sobek et al., 1978). 
Fizz Rating Description Amount of Acid Strength of Acid
0 - None No reaction. 20 ml 0.1 M
1 - Slight Minimal reaction; a few bubbles per 40 ml 0.1 M second to many fine bubbles.
2 - Moderate Active bubbling with only a small 40 ml 0.5 M amount of splashing.
3 - Strong Very active bubbling that includes 80 ml 0.5 M substantial splashing.
