bacteriological investigations of the Tugela River system (Natal), 
            
75
using methods consistent with those described in Part I of the series. 
            
76
The findings indicate that, except at relatively few locations where 
            
77
pollution was detected, overall water quality was generally good 
            
78
(Classes I and II) across much of the system. Mineral pollution 
            
79
associated with coal mining districts in Northern Natal was observed, 
            
80
strongly affecting smaller streams but having limited influence on 
            
81
major rivers due to dilution. Organic pollution was detected at 
            
82
several points, most notably in the Little Bushman\u2019s River at 
            
83
Estcourt; however, the report notes that pollution in the Tugela 
            
84
system was generally less intense than in the \u201cThree Rivers 
            
85
Region\u201d (Part II). The report compiles survey work conducted 
            
86
across multiple years and tributaries (including the Buffalo, Sundays, 
            
87
Bushmans, and Mooi rivers), includes river zonation and flow 
            
88
discussion, and concludes with a classification of water quality at 
            
89
sampling stations (1965 survey). An appendix provides a detailed 
            
90
discussion of mineral pollution from coal mines, explaining its origin 
            
91
(pyrite oxidation), impacts, and challenges for pollution abatement.",
