The legacy of industrial pollution of the subsurface has highlighted the need to promote better environmental stewardship as the economies of nations continue to grow. Environmental degradation of the near-surface Earth has resulted in long-term damage to groundwater and soil resources. Subsurface pollution is a significant public health concern, particularly given the increasing dependence of nations on groundwater to meet water usage and consumption demands. Geophysical methods are increasingly being employed in attempts to characterize the extent of such degradation and monitor the effectiveness of biogeochemical processes directed at remediating contaminants. One of the most challenging long-term groundwater contamination problems is a direct consequence of the legacy of nuclear weapons development and testing. In order to illustrate the contribution that geophysics is now making to such environmental legacy issues, Johnson et al.
The common forms of industrial pollution from heavy industries or large-scale manufacturing include high loads of heavy metals (particularly lead, mercury, and cadmium), oil and grease, biological oxygen demand (BOD), and suspended solid, which affect all components of the river and marine environments (Yusoff et al., 2006). Over 80% of the total volumes of industrial wastes in Malaysia originate from food and beverage processing, chemical products, and agro-based industries (palm oil, rubber manufacturing, and leather and textile products) (Table 20.2). Agro-based industries contain very high concentrations of suspended solids, organic material, nitrogen, and phosphorous, which lead to rapid depletion of DO in surface water (Ibrahim et al., 2010; Ismail, Noordin, Abu Talib, & Junaidi, 2003).
Treatment or end-of-pipe treatment or pollution control is one of the very important technologies for the traditional waste management hierarchy and environmental compliance for any industry. There is a variety of traditional treatment technologies for wastes to choose from depending on several factors such as physical form of the waste (solid, liquid, or gaseous), quantity of waste, characteristics, combined or segregated wastes, degree of treatment required, etc. The treatment technologies can be categorized into physical, chemical, thermal, or biological treatment. Combinations of treatment technologies are often used to develop the most cost-effective, environmentally acceptable solutions for waste management.
Physical processes for waste treatment include screening, sedimentation and clarification, centrifugation, flotation, filtration, sorption, evaporation and distillation, air or steam stripping, membrane-based filtration processes, etc. These processes are mostly applied to liquid hazardous wastes, and involve the separation of suspended or colloidal solids from the liquid phase. The selection of the technology depends mainly on the concentration and characteristics of the suspended solids relative to the liquid phase. Physical processes segregate the waste from one form to another, reduce the volume, and concentrate the solids to facilitate further treatment or further actions. Whenever a waste containing liquids and solids is to be treated, physical separation of the solids from the liquid should be considered first because it is generally cost-effective to treat a low volume, high concentration waste. Usually physical treatment is used in combination with other treatment technologies for optimum waste treatment and disposal.
Chemical treatment involves the use of chemical reactions to transform harmful waste into less harmful, or non-harmful waste, or make it less mobile in the environment. Many different types of chemical treatment processes are used in waste management such as neutralization, precipitation, coagulation, flocculation, oxidation, reduction, etc. Chemical treatment can have some advantages such as volume reduction and promoting resource recovery from wastes. Because it can be employed for resource recovery, and to produce useful byproducts and environmentally acceptable residues, chemical treatment should be considered before sending an untreated hazardous waste to an off-site landfill for disposal. Also, since liquid wastes should not be disposed of in a landfill without prior treatment, chemical treatment is often used to make it either non-hazardous, or at least chemically convert it to a solid or semi-solid, which makes the contaminants chemically stable and not very mobile in the landfill environment.

Answer:
i don't think so.
Explanation:
nature is more important than these industries because nowadays it is so difficult to breath. in my opinion it shouldn't be promoted.
