Discharge of fly-ash from thermal, electric and atomic power plant and coal washries from lignite mining are serious source of water pollution which severely polluted paravanaru river, Neyveli, Cuddalore district,Tamil Nadu. The physico-chemical analysis of the thermal power station effluent showed high alkalinity, BOD , COD values and more total dissolved salts. Effect<span style="mso-spacerun: yes;">                                     </span><span style="mso-spacerun: yes;">                                                                                             </span>of various concentration (viz.10%, 25%, 50%, 75% and 100%) of the effluent was tested on seed germination and biochemical changes of groundnut (<em style="mso-bidi-font-style: normal;">Arachis hypogaea</em>) seedlings. <em>Eichhornia crassipes</em> (water hyacinth) and <em>Pistia stratiotes</em> (water lettuce) which have been employed for waste water treatment for 48 hours (B.T.E). The results indicate that the lower concentration there is a significant increase in the percentage of seed germination, growth parameters and pigment contents. But it decreased with the<span style="mso-spacerun: yes;">  </span>increase of thermal power effluent above 25%. Therefore the 25% effluent (B.T.E) dilution was found to be most suitable which can be used as a liquid fertilizer. </span></p><p style="text-align: justify;"><span style="line-height: 110%; font-family: ";Garamond";,";serif";; font-size: 10pt; mso-fareast-font-family: SimSun; mso-fareast-language: ZH-CN; mso-bidi-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-bidi-language: AR-SA;">---</span></p><span style="line-height: 110%; font-family: ";Garamond";,";serif";; font-size: 10pt; mso-fareast-font-family: SimSun; mso-fareast-language: ZH-CN; mso-bidi-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-bidi-language: AR-SA;"><p class="MsoNormal" style="text-align: left; line-height: normal; text-indent: 0in; margin: 0in 0in 0pt;" align="left"><em><sup><span style="font-family: 'Garamond','serif'; font-size: 10pt;">1</span></sup></em><em><span style="font-family: 'Garamond','serif'; font-size: 10pt;">Department of Botany, Bharathiyar University, Coimbatore.
