Comments "Based on values from seven sites and four studies (31, 37–39), the average number of unattached cells in groundwater is 1.54?10^5 cells/ml. The total volume of groundwater in the upper 4 km of the earth’s surface is 9.5?10^21 cm^3 (40), and thus the number of unattached prokaryotes in groundwater is 1.46?10^27 cells."
