Betwa an important river in central part of state of Madhya Pradesh originates from village Jhiri of Raisen District and travels through the industrial belt of Mandideep and Bhojpur. After flowing through several cities of Madhya Pradesh it enters the neighboring state Uttar Pradesh at Hamirpur and finally joins in Yamuna River. However the quality of river water deteriorates at several places due to inflow of sewage, industrial effluents, agricultural residues etc. from its adjacent catchment at many places. The major problem of Betwa River is the discharge of industrial effluents and sewage from the Mandideep Town besides other cities. The accrual of toxic elements from the discharge of effluent and nutrients from the eroded river banks, agricultural field has resulted in increasing level of nutrients as well as certain heavy metals like Cr, Cd, Zn & Cr. Most of the water-spread area of the riverbed has also become shallow and subsequently almost three forth part of the bed near the industrial area is covered with infestation of weeds the making the water unfit for domestic uses. The present paper deals with the seasonal variation of limnochemical and toxicological characteristics of river Betwa during the winter months (October 2016 to December, 2016. For the present study four sampling stations were selected viz. Station-I Jhiri, Station-II, Mandideep, Station-III; Bhojpur, Station-IV; Vidisha. The outcome of the studies revealed high values of certain parameters like BOD and COD at Station III Mandideep. The paper highlights the impact of the Industrial effluents on Water Quality of the River near Mandideep region.

The present study was conducted in Betwa River near Mandideep Industrial Area extending from origin up to a stretch of 200 kms downstream to assess the presence of selective pesticides in the river water. Quarterly analysis was carried out during 2016-17 for water samples collected from surface and bottom waters at stations of Betwa River in Mandideep area. The study reveals the presence of few pesticides viz. Aldrin, Endosulphan and HCH, in traces at all the stations except its origin. Presence of Pesticide, though in low concentration suggests primary entry of it into river water which may be attributed to run offs from nearby agricultural fields. The present study emphasizes the need for alternative agricultural practices with application of organic bio-pesticides instead of depending heavily on chemical pesticides.
