From the analysis, pH of the all samples were varying from 6.64 to 8.17. The pH values are within the permissible limit. In Natham taluk, bore wells samples showed extreme (991, 963 and 951 mg L </span> <sup> <span style="font-size:12px;">-1 </span> </sup> <span style="font-size:12px;">) total dissolved solids (TDS) values when compared to maximum permissible TDS is 600 mg L </span> <sup> <span style="font-size:12px;">-1 </span> </sup> <span style="font-size:12px;">. The taste of water comes under poor TDS rating. The highest total hardness (TH) 725 mg L </span> <sup> <span style="font-size:12px;">-1 </span> </sup> <span style="font-size:12px;"> was tested at Silukuvarpatti bore well in Nilakottai taluk. Residual free Chlorine and Iron were not detected in any of the samples. All samples showed Nitrate (NO </span> <sub> <span style="font-size:12px;">3 </span> </sub> <sup> <span style="font-size:12px;">- </span> </sup> <span style="font-size:12px;">) concentrations were ranged from 0 to 25 mg L </span> <sup> <span style="font-size:12px;">-1 </span> </sup> <span style="font-size:12px;">. The values are less than NO </span> <sub> <span style="font-size:12px;">3 </span> </sub> <sup> <span style="font-size:12px;">- </span> </sup> <span style="font-size:12px;"> desirable limit, that is 45 mg L </span> <sup> <span style="font-size:12px;">-1 </span> </sup> <span style="font-size:12px;"> respectively. Maximum number of samples showed chloride (Cl </span> <sup> <span style="font-size:12px;">- </span> </sup> <span style="font-size:12px;">) values were higher than Cl- permissible limit (1000 mg L </span> <sup> <span style="font-size:12px;">-1 </span> </sup> <span style="font-size:12px;">) as referenced by BIS. The highest Cl </span> <sup> <span style="font-size:12px;">- </span> </sup> <span style="font-size:12px;"> values were obtained at 2950 and 2000 mg L </span> <sup> <span style="font-size:12px;">-1 </span> </sup> <span style="font-size:12px;"> in Pudukkottai well and Sengulam bore well taken from Reddiyarchatiram and Natham taluks. In regards to fluoride (F </span> <sup> <span style="font-size:12px;">- </span> </sup> <span style="font-size:12px;">) contamination, thirty-four samples showed < 0.5 ppm F </span> <sup> <span style="font-size:12px;">- </span> </sup> <span style="font-size:12px;"> and rest of fourteen samples viewed <1ppm F </span> <sup> <span style="font-size:12px;">- </span> </sup> <span style="font-size:12px;">. According to BIS and WHO standard, low concentration of F </span> <sup> <span style="font-size:12px;">- </span> </sup> <span style="font-size:12px;"> below 0.5 ppm may increase the risk of tooth decay. </span> </div>}, number={1}, publisher={Mehmet Sinan Bilgili}
