  • Assessment of Water Quality in Vaigai River
    Volume 3 Issue 2 December 2017 www.irjes.psyec.edu.in ASSESSMENT OF WATER QUALITY IN VAIGAI RIVER A.Anbil Dharmalingam PG Scholar ,Department of civil Engineering, Pandian Saraswathi Yadav Engineering College, Sivagangai,Tamilnadu, India. Abstract The Surface water such as rivers, lakes, is connected to ground water and vice verse. This connection is usually through wetlands and springs. (A good way to think of this is the cold water that you may suddenly feel when you swim in a lake. That’s ground water entering the lakes as a spring). Ground water and surface water are connected, so pollution can pass from one to the other very easily. The ground water is extracted from Vaigai River in Theni, Madurai, Dindigul and Sivagangai region to meet municipal, agriculture and other water requirements. This present study is mainly concerned about the quality of water Vaigai dam – outlet, Thenur pirivu – near Melakkal, Perani - S.Mettupatti, Dindigul, and Madurai region , Manaloor – Thirupuvanam, Sivagangai. Surface water samples are collecting in the above places, in stretch of origin of rivers and the samples are subjected to a comprehensive surface water analysis to study about the present status. Keywords: water quality assessment- Physical – chemical parameter-vaigai river Introduction Assessment is the overall process of evaluation of the physical, chemical and biological nature of the environment in relation to natural quality, human impacts and intended uses – Includes the use of monitoring data (practical, desk‐based or on‐line data collection) – Includes interpretation of the data – Aims to define environmental conditions, detect trends, establish cause‐effect relationships.

    Bee. zool. $urv. India,. 89( 1-4) : 233-243, 1991. REPORT ON THE ICHTHYO FAUNA OF ANNA AND MADURAI DISTRICTS" TAMIL NADU T J.INDRA Zooloqrcal Survey of India, Madras INTRODUCTION During the years 1986-1987, Zoological Survey of India, Southern Regional Station, carried out two extensive surveys of Anna and Madurai Districts, in Tamil Nadu, under the Mopping Survey Scheme. Madurai District is traversed by the river Vaigai and its tributaries such as Theni, Surali and Moolar. These are seasonal rivers. Apart from these water ways there are few lakes i.e. Kodaikanal Lake and Berijam Lake in Anna District. Some water falls and hillstreams were also surveyed for their Ichthyo fauna. The Vaigai Dam across' Vaigai river near Madurai and Sathiar Dam also near Madurai were also surveyed. No comprehensive account on the fish fauna of Anna and Madurai Districts is available and therefore, a list of fishes from these districts is worth reporting. The data under each species includes its first reference, number of examples, their size range in mm. in standard length, area of collection, date of collection, geographical distribution and remarks (wherever variations are observed). In all there are 34 species in the present collection of 560 examples (503 adults and 57 juveniles) belonging to 9 families. Puntius arenatus (Day) is being reported for the first time from Vaigai Dam. Puntius filamentosus (Valenciennes) and Puntius mahecola (Val.) were treated as two distinct species in accordance with the findings of Selvaraj, Mathew and Abraham (1986-87). Jayaram (1981) was followed for the identification and distribution of fishes.

ANANDAN MINISTER FOR FORESTS © GOVERNMENT OF TAMIL NADU 2014 DEMAND No.54 POLICY NOTE 2014-2015 FOREST DEPARTMENT INTRODUCTION "kâÚU« k©Q« kiyÍ« mâãH‰ fhL« cilaJ mu©" - ÂU¡FwŸ (742) "A fort is that which owns fount of waters crystal clear, an open space, a hill, and shade of beauteous forest near." - Thirukkural (742) The ancient Tamil poets have emphasized the importance of dense forests, clean water and fertile soil in providing ecological security to the mankind. Forests are a complex eco-system which play a dual role of a renewable resource and also as a vital support base for safeguarding the overall environment and ecological balance. It is forest cover that has preserved the soil and its heavy humus that has acted as a porous reservoir to 1 retain water and is gradually releasing it in a sustained flow over a period of time. Trees draw water from the earth crust and release it to the atmosphere by process of transpiration as a part of water cycle. Trees also purify the air by releasing oxygen into the atmosphere after consuming carbon-di-oxide during photosynthesis. The survival and well-being of any nation depends on sustainable social and economic progress, which satisfies the needs of the present generation without compromising the interest of future generation. Spiraling population and increasing industrialization have posed a serious challenge to the preservation of our terrestrial and aquatic ecosystems. Overexploitation of our resources due to rapid population growth has lead to degradation of forests and denudation of agricultural lands.
