Rapid Industrialization take part a key role in wealth of a country. Enormous growing Industrialization has resulted in production of liquid and solid wastes. Disposal of industrial wastes, especially on land has caused serious environmental problems. Land contamination is a severe issue as it alters the index and engineering properties of soils. Alteration of soil properties from industrial wastes results in foundation failures and structural damages. The present study communicates the study on index properties of alkaline soil by the application of partially treated Pharmaceutical industrial effluent. In this investigation, studies were conducted for identification of alkaline soils and analysation of industrial wastes of Pharmaceutical and also index properties of existing soil and blended pharmaceutical effluent soil.

CHANGES ON PHYSIO-CHEMICAL PROPERTIES OF SOIL IN AGRICULTURAL LAND IN AMBO-GUDER WATERSHED, AMBO, ETHIOPIA -A CASE STUDY_Dr. Subash Thanappan (Associate Professor, Department of Civil Engineering, Ambo University, Ethiopia) et.al.,2017 •
Water and wind induced soil erosion has adverse economic and environmental impacts. This research work is an assessment of the impact of soil erosion on land degradation at Ambo-Guder watershed zone, Ambo town, Oromia regional state. A rural village, Guder, is subjected to land degradation due to forest degradation, agricultural activities, human settlement and hard rock mining. The outcome of the land degradation is the extensive soil erosion and gully formation in the sites under study. These activities to a large extent have affected the production and productivity in the kebele. To achieve the stated objectives, data were generated through questionnaire and direct field observations and measurements. Soil erosion strategies were observed in three distinct sites categorized as human settlement areas, cultivation and grazing sites and near mining areas. Samples were collected from these sites and physico chemical parameters were assessed through laboratory analyses. The results of the study revealed that the area under study is degraded due to soil erosion. Key words: Agricultural, Cultivation, Vegetation, Kebele, Degradation

There has been an increase in number of pharmaceutical companies in the present time. A large number of them are located in Himachal Pradesh. The effluents from these industries contaminate the nearby soil and water bodies. Here we analyses the treated waste water and soil from nearby areas for their physical, chemical and biological parameters. The samples were analyzed using standard methods according to WHO & APHA-AWWA-WPCF norms. The results showed a high amount of contamination. The pHs of the water samples showed contrasting features one being slightly alkaline while other highly acidic. The microbial activity was quiet low in the treated waste water while optimum amounts of bacterial and fungal activity was found in the soil samples near the industries. The presence of high amount of sodium and salinity was also observed. This could damage the crop productivity and soil fertility. There is an urgent need to propose strict restrictions on discharge of harmful effluents in the environment.
Assessment of groundwater pollution along Thippagunta drain, the physical and chemical characteristics such as colour, turbidity, odour, pH, Electrical Conductivity, Total dissolved solids, Total Hardness, Calcium, Magnesium, Nitrate, Sulphate Chloride, Fluoride and Iron were studied. The main objective of the study is to know the quality of water for drinking and its impact on the public health of Prasadampadu. All the parameters of groundwater samples in the study area are within the permissible limits except at industrial Estate and Johnson Private Limited Industry, near Pantakaluva.
The present study aims to evaluate the waste water management system in Jeedimetla effluent treatment plant limited, Hyderabad. Industrial Estates have become common feature of global landscape. Industrialization and pollution are like two side of the same coin. The goods and services are the result of Industrialization, which leads to the pollution of water, air and other natural resources. So, the need for treatment of waste water is utmost important in the environment perspective. Industrial waste contains toxic compounds have their own adverse effects which in turn effects ground water, which stimulates the growth of aquatic flora and fauna. So, the Effluent released from the industries cannot be directly disposed onto the land, they need some treatment before disposal to avoid contamination of soil, ground water etc.., that contain unacceptable amounts of suspended solids, dissolved solids, minerals etc.., which are dangerous when disposed without treatment. In the present study different Physico chemical parameters were analyzed like PH, The report emphasizes on the biological treatment process of combined waste water, design their operation and maintenance and also the safety measures that are to be taken. The process achieves 90% BOD removal.
The present study was conducted in urban area of Khammam region for the investigation and assessment of physico –chemical analysis of ground water. The samples are collected in day time from different cites of urban area of Khammam
Expansive soils pose great problem to the structures found on them. When their extent is very large the only option to cater the problem is to stabilize them. Chemical stabilization proves to be the most suitable among the other methods. This paper gives an insight to the behavior of the expansive soil and the properties of the constituting clay mineral, and the mechanism of stabilization with lime. The cyclic behaviour of the expansive soil is also important when the stabilization is carried out, as the lo of the chemicals is necessary for the brief account of the cyclic behaviour and the laboratory methods to assess it. It give reasonable exposure in terms of geotechnical practice.
Construction and demolition waste constitutes a major portion of total solid waste production in the world, and most of it is used in land fills. One way of profitable use of wastes is the possibility of treating and reusing as aggregates in new concrete. In this paper, construction and demolition Wastes, have been studied for effective utilization in concrete. The study objective was to determine the quality of recycled aggregate such as the crushing value, absorption, density, attainable grade of concrete, and establishing the structural properties of the fresh as well as hardened concrete. The study was achieved by doing different tests on the recycled aggregates, Specimens preparation and assessment of properties of concrete in both fresh and hardened states. Most of the test results of properties of recycled aggregates have not met the minimum requirements suggested by codes, but the grade of concrete intended to be achieved was met. In conclusion, it has been found that recycled aggregates are suitable in making concrete. Also some barriers on the use of recycled aggregates have been identified, such as lack of awareness, and non-existence of specifications/codes for guiding the reuse of aggregates in new concrete.

Eco enzyme is a fermented solution from mixture of sugar, fruit wastes and water in the ratio of 1:3:10. It can be used as pretreatment for aquaculture sludge before other further treatments in order to minimize various environmental problems that caused by high nutrient contents of the sludge. In this study, the characteristics of the eco enzymes (tomato and orange wastes) were investigated and its potential efficacy of parameters removal within 10 days treatment was also evaluated. Results showed the enzymes were acidic, composed of high total solids (TS), total dissolved solids (TDS), biological oxygen demand (BOD), chemical oxygen demand (COD), citric acids and contained biocatalytic enzyme activities which are protease, amylase and lipase. The enzymes were also showed a higher removal percentage of total suspended solids (TSS), volatile suspended solids (VSS), total phosphorus (TP), total ammonia nitrogen (TAN) and COD approximately 87%, 67%, 99%, 91% and 77% respectively in the optimum concentration of eco enzymes (10%). Besides, use of orange eco enzyme (OEE) was showed higher removal percentage compared to tomato eco enzyme (TEE) due to high organic acid contents. These findings may contribute to the effectiveness of enzymatic pretreatment which can reduce the inhibitors and improve further treatment processes in treating other industrial wastes

Water is an essential component for the existence of life on the planet earth. It is a tasteless, odourless, and nearly colorless liquid. In some way or the other, it also full fills the need of minerals in our body up to a certain limit. But the anthropogenic activities leads to the imbalance of these minerals in water resulting in degradation of its quality. Today, it is a known fact that the groundwater quality is degrading day by day which is a serious matter of concern, as poor quality water pose threats to health and hygiene of living beings. Good quality of water is of utmost importance for survival of man and animals. The present study aimed at assessing the status of the groundwater in Sikandra Rao and its adjoining villages. In the light of aforesaid facts, it becomes necessary to assess the current groundwater quality in study area on the ground of various parameters such as temperature, pH (6.5-8.5), Turbidity (0.85 NTU-3.00 NTU),
