Every  water body in the world will undergo the eutrophication process naturally, unfortunately,  the presence of mankind activities such as agricultural and sewage runoff, wi ll speed up  the  process  which  caused  a  lot  of  environmental  issues  to  the  world.  This  study  was  undertaken ex-situ where the overall aim of this study is to treat the eutrophic man-made  lake of KOTASAS lake  water  through following objectives; to identify the variation of  physicochemical  attributes  KOTASAS  lake  water;  Biochemical  Oxygen  Demand  (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), Oil and Grease through phytoremediation, to evaluate the potential  removal  of selected heavy metals;  Manganese (Mn), Iron (Fe), Copper (Cu)    and nutrients; Nitrate and Phosphorus  using  Eichhornia  crassipes  (water hyacinth) and Pistia  stratiotes  (water lettuce) and to  find  the  correlations between sampling points and physicochemical attributes using  IBM SPSS  Statistics analysis. The method of analysis of lake water sample was referred by Standard  Method  for  Examination  of  Water  and  Wastewater  23rd  Edition  (APHA).  Then,  statistical notation was conducted on the results obtained to identify the accuracy and  validity of data, which in this case, ANOVA (one-way factor) and correlation were used.  Referring to the statistical notation of (p<0.05),  shows  a conclusion on the significance  of the result and variables were made. It was justified statistically that the  data obtained  for each treatment using different types of plants are valid and concise. As a result, it is  found that water lettuce  (WL)  and water hyacinth  (WP)  have different nutrients and heavy  metals  removal  efficiency  but,  in  all  cases,  these  phytoremediation  agents  exhibited  nutrients removal efficiency from the range of 32% up to 57% followed by heavy metals  removal efficiency from the range of 30% up to 78%. Mostly, WL exhibited great Nitrate  and  Phosphorus removal efficiency, 54.68%, and 57.24% followed by WH which was  32.39% and 33.39% respectively. Then, as for heavy metals, WL also showed higher  removal efficiency for Mn,  Fe, and Cu  such as 51.59%, 78.99%, and 77.69% followed  by WH which was 30.64%, 61.28%, and 58.58%. Finally, with this achievement acquired  in phytoremediation technology employing to WL, it was the utmost importance for this  technology to be implemented for larger scales in the future. Hence, WL was suitable to  be used in controlling eutrophic lake due to its hyper-accumulating ability.20aFaculty of Civil Engineering Technology 0aUniversities and collegesxDissertations 0aTheses  2lcccRESTRICT
