The Ponnaiyar, the Malattar and the Gadilam are the major rivers draining the district.
The Ponnaiyar River flows from northwest to east in the district.
The Varaganadhi is also known as the Gingee River and drains the parts of Gingee and Vanur
taluks of this district. 16617 ordinary wells and 24885 tube wells in two blocks of Vanur & Marakanam

The depth to piezometric surface ranged from 2.8 to 11.25 m bgl during Pre monsoon and
0.5 to 6.35 m bgl during post monsoon. The yield of bore wells in favorable locations
vary from <1 to 6 lps.

The incidence of high total
hardness is attributed to the composition of litho units constituting the aquifers in the
district, whereas nitrate pollution is most likely due to use of fertilizers and other
improper waste disposal.
