Groundwater is one of the most useful water sources for sustaining life and environment. But over the last few Decades the water quality has been deteriorated due to its over exploitation. Contamination of such water source is a big problem creating health hazards. Groundwater is the major source of drinking water in rural as well as in urban areas and over 94% of the drinking water demand is full fill by groundwater. The study has been carried out to assess the ground water quality and its appropriateness for drinking in most rural habitations of Jhunjhunu district, Rajasthan, India. In the present study groundwater samples were collected from different villages of Jhunjhunu District, Rajasthan and assessed on the basis of various parameters. The water quality parameters such as; pH, TDS, electrical conductivity, total alkalinity, total hardness, calcium hardness, magnesium hardness, carbonate, bicarbonate, sodium, potassium, fluoride, sulphate and nitrate have been analyzed. The study revealed that the water confirms to drinking water quality standards at some places whereas at some places it was totally unfit for human consumption.Keywords

Aim:
The ligands contain O, N, S-Sequence and their metal complexes have their various chemical and structural characteristics and their wide application in the field of pharmacology. The extreme efforts have been made to design novel drug to strains of resistant micro-organisms. This has required the need to search for more efficient drugs.
The Zn (II) metal complexes with a tridentate ligand 2,5-diamino-1,3,4-thiadiazole has been prepared by cyclisation of bithiourea in a 3% hydrogen peroxide medium. 2,5-diamino-1,3, 4-thiadiazole acts as neutral tridentate ligand and coordinates through the sulphur atom and nitrogen of the amines. The complexes are non-electrolyte in DMF. The complexes exhibited octahedral geometry. The antimicrobial activities of ligand and its complexes were screened using sensitivity test, minimum inhibition concentration and minimum bacterial concentration method. Metal chelates showed greater antimicrobial activities as compared to the control and the ligand. The metal chelates and the ligand did not exhibited activity against Aspergillus niger and Penicillin species.
Methods:
Elemental analyses, IR spectra, magnetic susceptibilities by using Faraday Balance, molar conductance by using Genway 4200 conductivity meter. Metal estimation by using Alpha 4 Atomic Absorption Spectrophotometer. Thin layer chromatography was carried out using TLC plate coated with silica gel.
Results:
The results of the elemental analyses are in good agreement with those calculated for the suggested formulae, 1:2 (M: L) solid chelates are isolated and found to have the general formulae [(ML2)] X2; M=Zn (II) (X=Cl).
The IR spectra revealed that the ligand L is a neutral tridentate ligand. It coordinated to the metal ions via the nitrogen of the amines and sulphur atom. The molar conductance value of the Zn (II) complex was low which indicate the nonelectrolytic nature of the complex. The ligand and metal complexes show antimicrobial effect against the tested organism species except against molds of penicillin and Aspergillius. Niesseria gonorrhoea was probably the most sensitive organism to the 2,5-Diamino-1,3,4-Thiadizole and its metal complexes. Metal complexes showed greater activity against some of the micro-organisms compared to the parent compounds
Conclusion:
In this paper we conclude from combined results of the chemical and physical analysis that the ligand (2,5-diamino-1,3,4-thiadiazole) coordinated with Zn. The metal complexes possess better physical properties than the parent compound. Metal complex of 2,5-diamino-1,3,4-thiadiazole would be a better therapeutic drug for antibacterial treatment.

The Cyclic imides and their Derivatives have been attracted significantly more attention of organic and medicinal chemists due to their antimicrobial activities. The derivatives of six member cyclic imides were synthesized by the action of glutaric anhydride with different substituted aromatic amines to obtained 4-(N-phenylcarbamoyl) butanoic acid. These intermediates undergo ring closer with acetyl chloride furnished six member cyclic imides derivatives. All these derivatives were screened for their antimicrobial activities.Keywords

The water has become an emotive issue with the people. The paper presents groundwater quality assessments of Pilani Town District Jhunjhunu, Rajasthan India. The water samples were collected from 10 open wells, tube wells and hand pumps in Pilani. Ground water is increasingly being sought as a source of drinking water due to the scarcity, non-availability and bacteriological pollution of surface water. This paper describes the important results of the Physico-chemical Assessment of the ground water samples of the open wells, tube wells and hand pumps of the urban areas in Pilani, District Jhunjhunu of Rajasthan. The different parameters determined are pH, TDS, fluoride, chloride, nitrate, sulphate, total alkalinity and total hardness. It has been observed that nitrate values are higher compaired to ICMR standards. Other parameters were found within desirable limits. The interesting fact is that the nitrate alone is making ground water unfit for drinking.Keywords
