The city is bounded by two rivers, increasing eutrophication followed by Chakrapani the Cauvery River on the north and Arasalar River on the temple. The present study recommended that awareness south [6]. programmes should be taken up in the adjoining locations of the city to awake people about the There are around 188 Hindu temples within the detrimental effect of water pollution in the temple municipal limits of Kumbakonam. Apart from these, there ponds. All the tanks should be periodically recharged by several thousand temples around the town thereby giving the freshwater through proper inlet and outlet channels. the town the sobriquets "Temple Town" and "City of temples".

INTRODUCTION B. Selected Temple Tanks The following temples are situated within the Water is most important for the presence of life on Kumbakonam city. These temple ponds are regularly used earth. Mainly the freshwater resources are considered as by the local people and devotees during the year: one of the most necessary natural sources for all the living things [1]. Less than 1% of water is readily available in Mahamaham Tank (MMP): one of the most prominent ponds, lakes, rivers, dams, streams, canals, which is used landmarks of the town. It is one of the largest ponds in for industrial, domestic and agricultural purposes [2]. the city. It is being used for a holy dip by the people every 12 years. Ponds are one of the significant water resources in Saeikulam Tank (SKP): It is a common tank for the urban and rural India. There are nearly 1000 temple tanks public. The people are using this tank for all domestic in Tamil Nadu. The pond is very essential and sustainable purposes. It is fully fenced and prevents the management for harvesting rainwater to assure the contamination of the surface run-offs. groundwater level [3]. Temples are centres of worship for Chakrapani Temple Tank (CPP): It is a Hindu Hindus. The devotees use many ponds as the holy water for temple dedicated to Vishnu located in Kumbakonam. washing their limbs, sometimes they make a holy dip into This temple is located 2 km, away towards North West the water, and people believe that it can wash all their sins from the Kumbakonam Railway Station. The temple is away. However, temple ponds located outside temples are one of the most prominent temples in Kumbakonam. used by people for bathing and washing their clothes [4]. Portramai Tank (PTP): It is located between Sarangapani and Kumbeswara temple at Kumbakonam The addition of Industrial effluent and municipal on Thanjavur route, approximately 2 k.m from new bus- wastewater are affecting Physico-chemical characteristics stand.

Overuse of behind the Chakrapani temple in Kumbakonam, which water extraction has led to many of them drying up, inlets is ancient Aadhi Varaha Perumal Kovil, a temple that have been blocked by construction activities, and dates back to the Varaha Avatar. It has also a large tank population pressure resulted in some drained and used for when compared to others. other purposes [3].

Grab sampling method was followed polluted (76 - 100) and unfit for consumption (above 100) during the sampling. The water samples were analyzed for based on their suitability [13]. 12 physico-chemical parameters using standard methods [8]. III. RESULTS AND DISCUSSION D. Water Quality Index A. Water Quality Characteristics Water quality index (WQI) is commonly used for the The results of physical and chemical characteristics of detection and evaluation of water pollution and may be selected temple tanks in Kumbakonam city were presented defined as “a rating reflecting the composite influence of in Table 1-3. different quality parameters on the overall quality of water”. WQI was calculated by the weighted arithmetic pH: The pH of the water samples varied from 7.0 index method [9, 10, 11]. Twelve parameters were taken (January) to 8.5 (March) in Kumbakonam temple tanks. for calculation of water quality index: pH, TDS, turbidity, The high pH values were found during March all temple - 3- ponds except AKP. The minimum values were observed 2+ 2+ - hardness, total alkalinity, DO, Cl , Ca , Mg , F , NO & in January month except for CPP. The pH of water 2- SO . samples was found in alkaline nature during the study 4 period. The alkaline character of water may be due to The relative weight of each value in the overall water high temperature (during March) that reduces the quality was computed regarding the drinking water dissolution of carbon dioxide and also due to standards recommended by the Bureau of Indian Standards photosynthetic process. pH changes in water were due [12]. to discharge of urban wastes, human activities and surface run-off [14]. Wi = K/Sn Where, K = constant value of proportionality is calculated as Total Dissolved Solids: TDS of all water samples are recorded with a maximum value of 650 mg/L in March 1 K and a minimum of 200 mg/L in January. The elevated 1/S1 1/S2 1/Sn value of TDS during March month can be due to the Si - the standard value of the ith parameter adding of garbage, domestic and municipal sewages, etc [15].
