Contamination, Pollution and Quality

The goal of safe and affordable drinking water and sanitation has not yet been achieved. The current practices of water purification are inadequate to produce secured water supply. Maintaining health protection at water supply systems has become more challenging with resistance of some pathogens to disinfection using chlorination and an increase in the immuno-compromised population (e.g., people with HIV, organ transplant patients, the elderly).

In this context, it has become essential to develop various tools such as Composite Correction Programme (CCP) and Water Safety Plans (WSP) to improve water purification and distribution systems, to achieve the goal of providing safe drinking water.

The quality of drinking water is a vital element of public health and well-being. The most effective means of consistently ensuring the safety of a drinking-water supply is through the use of a comprehensive risk assessment and risk management approach that encompasses all steps in water supply from catchment to consumer.

WHO guidelines on water quality term these approaches as water safety plans (WSPs), developed to organize, systematize and apply management practices in drinking-water quality.

This happened following a thunder burst on April 5.

According to Mahammad Ashlam of KBK Samachar, the local news agency, the downpour lasted 45 minutes and resulted in a huge run-off of the toxic waste into nearby water bodies from a crack in the pond wall of the one-million-tone refinery. Red mud or bauxite residue is a waste product of the alumina manufacturing process.

This study by National Environmental Engineering Research Institute published in Current Science was carried out to identify Pteris vitta and test its hyper-accumulating properties. The plant is commonly known as the Ladder brake fern or Chinese brake fern plant in India, and had been reported elsewhere as an arsenic hyper-accumulator.

.The remediation of arsenic and chromium contaminated soil and water has become an important environmental issue. It is in this context that the discovery of hyper-accumulator plant species, which have the unusual ability of accumulating metals such as arsenic (As), chromium (Cr), zinc (Zn), nickel (Ni) and copper (Cu) to very high concentrations, has further boosted technologies based on this property.

This is the first report of characterization of arsenic accumulation in an Indian ecotype (plant), which also shows chromium hyperaccumulation in addition to arsenic. Intact plantlets were grown in 20 per cent Hoagland solution amended with up to 200 mg arsenic or chromium medium. Plants absorbed and accumulated a significant amount of arsenic and chromium in their biomass with high bio-enrichment factor. Arsenic and chromium tolerance by spores and gametophytes under in-vitro was also assessed.

 Plasmid-encoding Carbapenemase-resistant Metallo-B-Lactamase (PCM or NDM-1) is an enzyme that makes bacteria resistant, not only to a broad range of antibiotics such as carbapenems and other β-lactam, but also to multiple other antibiotic classes, leaving very few treatment options available, when a person gets infected with such bacteria.

Following the invitation of Member of Parliament (Ludhiana) Mr. Manish Tewari, the Hon’ble Minister for Environment and Forests Mr. Jairam Ramesh along with officials of the Ministry of Environment and Forests including the Chairman of the Central Pollution Control Board, visited the site of the Buddha Nala in Ludhiana, Punjab in September of 2010.
