Pollution is a critical environmental issue. Currently an enormous amount of wastewater and fresh concrete waste aggregates are being produced by the ready mix concrete industry throughout the world. The concrete washout water and excess fresh concrete aggregates are hazardous for disposal due to their high pH value (pH>12). Improper disposal of such wastewater and fresh concrete aggregates results in high environmental pollution. This study envisages an overview of the current state of knowledge about the reuse of hazardous wastewater and concrete in an environmentally acceptable manner. This study was motivated by the necessity to recycle the wastewater and fresh concrete aggregates resulting from washing out the concrete mixing trucks. Laboratory investigation was conducted and from the test results, it is identified that the performance and properties of concrete is not affected by the reuse of this hazardous wastewater and recycled aggregates.Keywords

Groundwater is considered a vital natural resource due to its significant use for drinking, irrigation and industrial purposes. Groundwater has been a big variant in quality and quantity with respect to time and space. So the quality of groundwater has been assessed in Salem district. A detailed study was made in the study area for the quality of groundwater for drinking in premonsoon and postmonsoon based on the Water Quality Index (WQI). Groundwater samples were collected in sixty six locations in both premonsoon and postmonsoon in the year 2007. Various physicochemical tests were carried out and WQI was calculated based on pH, turbidity, total dissolved solids, total alkalinity, total hardness, nitrate, chloride, calcium, magnesium, iron and fluoride. The comparison between the premonsoon and postmonsoon reveals that in premonsoon season 56.06 %, and in postmonsoon 65.15% of the water samples were fit for drinking. The groundwater quality was found to be unfit for drinking in 22.72% of the samples in premonsoon and 18.18% of the samples in postmonsoon.Keywords

More than any other group of seabirds, gulls exploit a wide variety of food types and have evolved highly diversified foraging methods and habitats. This has been demonstrated among gulls, both in the family as a whole and within each species, and at all times of the year. As a long-distance migrant, gulls, especially in the non-breeding season, spend more time on large water bodies along the coasts or in the open ocean; as a result they flourish on fish and marine invertebrates as their diet. Gulls in general are thus opportunistic and omnivorous.Full Text
