Lake water quality degradation has been apparent for decades, especially in those lakes situated in the vicinity of cities which have anthropogenic activities. The present investigation was carried out for determining the various physico-chemical and biological characteristics of surface water quality of various lakes at Coimbatore, India. The sampling points were selected on the basis of their importance. Six sampling locations namely at Perur Lake (L 1 ), Selvachinthamani Lake (L 2 ), Ukkadam Lake (L 3 ), Kurichi Lake (L 4 ), Valankulam Lake (L 5 ), and Singanallur Lake (L 6 ) were selected and water samples were collected mostly from open wells in and around Coimbatore district. The physico-chemical parameters like Dissolved oxygen, Faecal coliforms, pH, Electrical conductivity, Biochemical oxygen demand, Chemical oxygen demand, Turbidity, Total dissolved solids, Sulphate, Nitrate, Phosphate, Chlorides and Alkalinity were analyzed. The results suggested that, the lake water samples collected from various sites in and around Coimbatore citywere above the limits of WHO standards.

This investigation deals with the determination of various physico-chemical and biological parameters of surface water quality of river Noyyal and its connected ponds at Coimbatore, India. Based on their significance, the sampling locations were selected. There are five sampling locations were selected like river Noyyal at sorce (S1), Perur Lake, (S2), Ukkadam Pond (S3), Singanallur Lake (S4) and Sulur Pond (S5), and samples were collected from each locations at river Noyyal basin in and around Coimbatore district. The surface water quality index determination is prerequisite and essential. In this present work, from different methods of water quality determination, the most commonly used index of National Sanitation Foundation water quality index (NSF-WQI) has been followed. The physico-chemical and biological parameters such as dissolved oxygen, faecal coliforms counts, pH, biochemical oxygen demand, phosphate, nitrates, turbidity, and total dissolved solids were investigated. Except in Noyyal river at source (S1) all the measured parameters are showed to be very high compared to limits suggested by WHO particularly during summer season and thereby it is not suitable for public use.

“…The systematic studies of correlation and regression coefficients of the groundwater quality parameters were useful to measure the overall groundwater quality as well as to determine the relative concentration of pollutants in groundwater. 19 Pearson's correlation coefficient (indicated 'r') is normally useful to find the relationship between the two variables. The parameters having r > 0.5 or < -0.5 are considered important.…”

Water Quality Index-WQI is useful to transfer complex information of the groundwater quality data into comprehensible and useable data. In this research work, the investigation is carried out by collecting 66 groundwater samples and amalgamating nine water quality parameters for evaluation of groundwater utilizing WQI in pre-as well as post-monsoon of a year in the villages of Gara Mandal of Srikakulam District in Andhra Pradesh. The results confirmed that most of the groundwater sample locations (54.5% of groundwater samples) showed poor quality in both pre-as well as post-monsoon seasons. On the other hand, the correlation matrix indicates the strong positive correlation exists between the chemical parameters like calcium ion and magnesium ion with chloride, sulphate as well as nitrate ion represents that groundwater in the sampling locations has been polluted due to geological conditions, seepage of sewage and anthropogenic activities. Hence a proper treatment is required before utilized for drinking.
