Groundwater is generally used for various purposes, particularly domestic and industrial purposes in all over the world. Fresh water from groundwater sources is high in the recent years and the groundwater is polluted high because of rapid population and industrial growth. It is very difficult to restore the contaminated groundwater by various pollutants.  Hence, it is important to analyse physico-chemical parameters of groundwater for its need for various sectors. Therefore, the present study was under taken to define the quality of groundwater with the help of WQI. The ground water samples were collected from 20 different places around Ambattur Industrial Estate in Chennai city. The groundwater quality assessment showed that the water quality of bore wells around Ambattur Industrial Estate is poor for drinking purpose as per WQI for BIS acceptable limit.  WQI observed from those selected 20 groundwater bore wells are ranging from 63.30 to 219.63.   The analysis reveals that the groundwater from the Ambattur Industrial Estate needs pre-treatment before it is being used for various purposes.

The objective of this work is to evaluate the physico-chemical quality of the groundwater of the Merdja plain and to determine the sources of mineralization. This quality is influenced by several environmental and anthropogenic factors such as geological context, climate, precipitation and interaction between groundwater and aquifers and human activities.  A Principal Component Analysis (PCA) on samples taken from several wells spread over the entire Tebessa plain (Merdja) allowed us to detect two axes that explain 73.4% of the information. The first axis describes the variables related to mineralisation and the second one describes those related to agricultural activity. Multidimensional Positioning (MDS) confirmed the interaction of physico-chemical parameters between them and their influence on groundwater quality by highlighting three groups of wells according to their physico-chemical characteristics, particularly those containing high concentrations of nitrates. This contamination is mainly the result of spreading the fertilisers and wastes that are dumped into the plain without treatment. Salinization is the result of long-term interactions between groundwater and geological formations.

The study assessed the effect of waste dumpsites on groundwater quality of upper aquifers in Port Harcourt. Water samples were retrieved from hand-dug wells from a dumpsite and a control site and analyzed for physico-chemical parameters and heavy metal content. Results show that electrical conductivity of the dumpsite water samples was 42.06μS/cm while the control site water samples recorded 31.27μS/cm. Turbidity of the water samples ranged from 0.62NTU-0.65NTU. Total Dissolved Solids of the dumpsite water sample was 26.8mg/l while the TDS of the control site water sample was 33.70mg/l. The pH of water samples from both sites ranged from 5.46 -7.34. The pH of water samples from the dumpsite was slightly acidic (5.46). The average temperature of the water samples was approximately 28oC. Phosphate concentration of water samples ranged from 0.32 mg/l-0.54 mg/l while chloride levels ranged from 10.60mg/l-17.12 mg/l. All physico-chemical parameters and heavy metal content of the water samples all fell within the WHO and NSDWQ stipulated standards except for the lead concentration of the water sample retrieved from the dumpsite. The study also revealed that waste dumpsites did not alter the concentration of the measured physico-chemical properties and heavy metal concentration of water samples. However, the study recommended that periodic assessments of groundwater quality of waste dumpsites should be undertaken

The main objective of present study is to evaluate the groundwater quality of Gulistan-e-Johar Town for drinking. For this purpose, groundwater samples (n=18) through electrically pumped wells were collected from shallow aquifers (mean depth = 36 m). Collected samples were subjected to determine the physical characters (TDS, pH, temperature), major (Na, K, Ca, Mg, Cl, SO 4 , HCO 3 , and NO 3 ) and minor ions (Fe, Mn and F). Data reveal very high content of TDS (mean: 2862 mg/L) coupled with elevated concentration of Na (mean: 974.6 mg/L), Cl (mean: 545.3mg/L), SO 4 (mean: 600mg/L), Mn (mean: 0.04 mg/L) and F (mean: 1.7 mg/L). The results indicated that groundwater of Gulistan-e-Johar is not suitable for drinking purpose and may lead to dangerous health impacts. The WQI value of groundwater is found to be 183 which is also endorsing that groundwater of Gulistan-e-Johar is unfit for drinking purpose.

Milk and dairy products play an important role in human diet due to their high nutritional and biological value, as well as to their easy digestibility. Milk powder makes it possible to improve the seasonal character of dairy foods. As a solvent in the production of reconstituted milk, water can significantly affect the quality of the finished product. In this regard, the problem of water quality and its preparation for the production of reconstituted milk is highly relevant. The method of separate freezing allows one to reduce the number of pre-treatment stages and energy costs. The research objectives were 1) to establish the effect of separate freezing on water quality indicators, 2) to determine the solubility index of milk powder in water prepared by the method in question, 3) to definethe energy costs. The research was carried out on the basis of the Department of Heat, Ventilation, and Air Conditioning Equipment (Kemerovo State University). The study was conducted with the help of a tank crystallizer with a controlling and measuring complex for registration of temperatures at temperatures from minus 2 to minus 10 C. In defining the quality of water and reconstituted milk, the authors used standard methods for determining its organoleptic and physico-chemical parameters. The study made it possible to define the organoleptic and physico-chemical parameters of water before and after separate freezing, the solubility index of dry milk, and the quality of reconstituted milk obtained by the method. The research revealed that it is energetically more advantageous to carry out the procedure at the temperature of minus 2 C. The present paper describes the numerous advantages of the method in that it reduces: 1) the dry residue content in tap water by 8 times, 2) the overall hardness of water by 2.5 times, 3) the content of chlorides and fluorides by 1.7 and 1.9 times, respectively, 4) the solubility index of milk powder from 0.35 to 0.1 cm3. All these factors improve the quality of reconstituted milk.

In this work, we will focus on the assessment of the quality of the Casablanca EST coastline, including bacterial and toxic water pollution, before the realization of the SIDI BERNOUSSI pre-treatment station. For this purpose, a set of analyzes were carried out on the littoral waters to evaluate the quality of sea water. This companion of analyzes includes: Analyzes on the surface of the sea water: Physico-chemical parameters: pH, temperature, biological oxygen demand BOD 5. Undesirables substances: Nitrates (NO3-), Ammonium (NH4+), Phosphates (PO4-), Hydrocarbons. Bacteriological parameters: Faecal coliforms and faecal streptococci. Sediment Analysis: Arsenic (As), Barium (Ba), Cadmium (Cd), Total Chromium (CrT), Copper (Cu), Iron (Fe), Mercury (Hg), Lead (Pb), Selenium (Se), Zinc (Zn). Biodiversity analyzes: For algae: Arsenic (As), Cadmium (Cd), Mercury (Hg), Lead (Pb). For mussels: Cadmium (Cd), Mercury (Hg), Lead (Pb). The results showed that the waters of the east coast of Casablanca are contaminated with pollutants in this case pathogenic bacteria, toxic substances including heavy metals and other toxic substances; on the other hand, coastal biodiversity is also affected. This contamination is due to industrial activity in the area. but remains below, for most pollutants, normative limits. For bacteriological pollution, beaches AIN SEBAA and NAHLA recorded a coliform contamination and faecal streptococci exceeding the values of the Moroccan norm of bathing water.
