Environment

For more than a quarter of a century, geo-physics has been used to improve man’s quality of life. The concern for a sound environment, which is not only free from pollution but whose natural balance has been respected, is one we all share.

Geo-physical studies are extremely useful in planning sanitary facilities, from the septic tank to the sewage treatment plant. Accurate knowledge of soil characteristics makes it possible to plan such installations and adapt them to the special condition of a particular site.

TVIPL has been involved in a number of projects for site characterization for waste disposal sites. For example, our firm recently completed a couple of projects for waste disposal sites in Visakhapatnam and Mangalore where seismic refraction, Cross hole seismic and Resistivity Imaging studies were conducted to have a detailed information of the sub-surface, water table, fractures and dynamic modulii, prior to construction phase. We have a number of techniques available to evaluate long term safety of solid waste storage sites. This is especially vital where toxic wastes are involved. The competence of the sub-soil, its earthquake resistance, porosity and permeability are all elements that figure essentially in the rational choice of a storage site.

As a specialist in mining, we can also economically solve problems of environmental pollution associated with mining operations.

Moreover, geo-physical studies can help locate source of pollution, both at depth and on the surface, which are likely to cause irreparable harm to underground water.

In order to define a problem in its entirety, TVIPL uses a number of complementary techniques:

The techniques help locating landfill sites and finding underground water tables. Advanced instruments are also used to locate marine, surface or underground pollution sources.

Once the investigation phase is over, TVIPL experts carry out Environmental Impact Assessment (EIA) and propose Environment Management Plan (EMP) including mitigation measures. TVIPL’s work for Bhopal Lake, comprising complete investigations and EIA, EMP for proposed dredging and desilting work, has been a landmark study for conservation of wetlands of national importance, thus contributing to the quality of life in the 21st Century.
