The physical, chemical and total heterotrophic bacteriological parameters (THBP) bacterial population were measured at three sampling stations namely Upper Anicut (S1), Chinthamani road bridge (S2) and Grand Anicut (S3) for a period of three month January to March 2007 in the river Kaveri, Tiruchirappalli. The pH ranged from 6.7 to 7.8, the level of solids and total hardness was high in station S2 when compared to other stations. Station 2 registered a minimum level of DO (3.6 mg l(-1)), and the BOD and COD varied from 3.47 to 4.27, 20.67 to 41.47 mg l(-1) respectively. THBP colony count was found to be high in S2 (8.16 x 10(2) CFU ml(-1)) and a lowest level in S1 (2.64 x 10(2)) and S3 (1.80 x 10(2)). It was observed in the present study that in reservoir (anicut) stations factors like pH, TDS, TSS, Hardness and THBP were at lower level than for the water at Chinthamani road bridge (S2), probably due to the mixing of municipal sewage at this point.
于2007年1月至3月的三个月期间，在蒂鲁吉拉伯利市科韦里河的三个采样站，即上阿尼库特（S1）、钦塔马尼路桥（S2）和大阿尼库特（S3），对物理、化学和总异养细菌学参数（THBP）细菌数量进行了测量。pH值范围为6.7至7.8，与其他采样站相比，S2站的固体和总硬度水平较高。2号站的溶解氧（DO）水平最低（3.6毫克/升），生化需氧量（BOD）和化学需氧量（COD）分别在3.47至4.27、20.67至41.47毫克/升之间变化。发现THBP菌落计数在S2站最高（8.16×10²CFU/毫升），在S1站（2.64×10²）和S3站（1.80×10²）最低。在本研究中观察到，水库（阿尼库特）站的pH值、总溶解固体（TDS）、总悬浮固体（TSS）、硬度和THBP等因素低于钦塔马尼路桥（S2）处的水体，这可能是由于此处有城市污水混入。
