Evaluation of The Effect of ANTHROPOGENIC Activities and Domestic Waste On Surface Water

The microbiological and organic pollutants characteristics of Owena dam in Ifedore local  government  area  of  Ondo-state,  Nigeria  was  carried  out,  nine  water  samples  were collected from three different parts of the downstream side, which include; around the waste disposal  site,  community  settlement  and  farm  environment.  The  microorganisms  isolated were  escherichia  coli,  enterobacter  species,  staphylococcus  aureus,  proteus  species, streptococcus species, pseudomonas species and saccharomyces species.  The  presence  and  absence  of  micro-organism  isolated  from  the  dam  water  sample with their total aerobic microbial count (TAMC) and total yeast mould count (TYMC) value at each station were; station 1, 1065cfu/ml and 72sfu/ml, Coliform, E-Coli, Staphylococcus Aureus,  Pseudomonas  specie  were  present,  Salmonella  Typhi  was  absent.;  station  2, 755cfu/ml  53sfu/ml,  Coliform,  Escherichia  Coli,  Staphylococcus  Aureus,  Pseudomonas specie,  Salmonella  Typhi  were  present.;  station  3,  400cfu/ml  and  25sfu/ml,  Coliform, Escherichia  Coli,  Staphylococcus  Aureus,  Pseudomonas  specie,  Salmonella  Typhi  were present. The  bacterial  isolates;  Escherichia  coli  ranges  from  6.3%  to  50.0%;  Enterobacter species, 10.0% to 50.0%; Staphylococcus aureus 25.0% to 37.5%; Proteus species, 30.0% to 40.0%; Streptococcus species, 15.4% to 61.5%; pseudomonas species, 12.5% to 50.0%. For the fungal isolates, saccharomyces species ranges from 7.7% to 53.8%. The  physiochemical  parameters  checked  for  in  the  dam  water  sample  range  is  as follow:  PH,  6.80;  temperature,  25oC  to  29oC;  conductivity,  35μs/cm  to  60μs/cm;  total hardness, 0.3mg/l  to  1mg/l;  total  dissolved  solid, 58mg/l  to  70mg/l;  total suspended solid, 25mg/l  to  120mg/l;  dissolved  oxygen,  4.0mg/l  to  4.9mg/l;  biochemical  oxygen  demand, 2.1mg/l  –  4.4mg/l;  nitrate,  27mg/l  to  28mg/l;  phosphate,  0.67mg/l  to  1.52mg/l;  sulphate, 110mg/l to 251mg/l; calcium, 10.7mg/l to 39.0mg/l. The microbiological and nitrate  results  showed that  the  dam water is  contaminated and must be treated before consumption
