Microbes, heavy metals slip past AMC water labs

# 8,000 Amdavadis were diagnosed with diarrhoea in 2014, up by about 25 per cent over the 2013 figure.
# Jaundice and typhoid have also raised their heads as their cases soared by 26 per cent and 44 per cent respectively.
 Despite the shocking surge in the water-borne diseases in the city, Ahmedabad Municipal Corporation’s water testing laboratories are not equipped to test advanced microbes and heavy metals and in drinking water as prescribed by World Health Organisation (WHO). This is not only contributing to rise in water-borne diseases but also damaging vital body organs like kidney, liver, bone and blood.

In the USA, 10 people per one million succumb to kidney ailment whereas, the number in Gujarat is five times higher, said by Dr HLTrivedi of Institute of Kidney Diseases and Research Centre.
Heavy metal in water is considered as one of the important causes for rise in such ailments. “Presence of heavy metal in water affects not only kidney but other vital organs like liver. It is important to keep drinking water free from such metals. And to do so water test should be done regularly to understand the amount of metal’s presence,” added Dr Trivedi.
However, he also added that due to rising usage of RO, the risk of heavy metal in water has reduced.
‘Man power required’
AMC labs’ inadequacy was first highlighted in a study published by Indian Institute of Public Health in 2013. The study stated, “The water samples are subjected to only basic physical and chemicals analysis. The capacity to test heavy metals (lead, cadmium, mercury, arsenic and nitrates), trihalothanes and fluorides and advanced microbial tests for bacteriophages and spores are not available.”
An AMC health official accepted that they don’t conduct the test at a regular interval, though it is required. “Currently, we don’t test heavy metals like lead, mercury, arsenic on a regular basis. In fact, there is no need for that because this kind of contamination is rare,” said AMC Health Officer Bhavin Solanki.
“It’s not possible to test such metals every day as it requires a lot of man power,” he added.
Solanki, however, accepted that these chemicals could affect vital organs in long term.
When Mirror tried speaking to the main correspondent of the study, Veena Iyer, she refused to share further information.
She, however, said, “Like Ahmedabad, water testing laboratory is unavailable at several places across the country. So, highlighting only one city is not justified.”
The study insists on periodic surveys and calls for improved testing strategy for drinking water.

Dr Sandeep Shah, a microbiologist, said: “Most of these metals affect our internal organs which in a long run can be fatal. With increasing industry and human dwelling, water contamination is on the rise. Hence, there is need for modified water testing strategy which can identify water contamination sooner.”
Ground water still in use
Though the city has been receiving Narmada water since 2000, the use of groundwater is still rampant at several places in the city where AMC does not supply water. The groundwater in Ahmedabad is known to have high levels of iron, fluoride, chloride and nitrates. Municipal corporations as well as rich housing societies routinely resort to groundwater to supplement their water needs.
“The present drinking water surveillance system of the municipal corporation is designed for 24-hour pipe distribution of treated surface water. In reality, the water supply is neither 24 hours nor exclusively treated surface water,” said the study. Ahmedabad receives approximately 1 billion litres of water daily. But, the supply is not metered. Therefore, the actual quantity of water consumed by residents is not recorded.


BOXXXX
Chemicals and their affect
Lead: It delays physical and mental development in children. It also increases in blood pressure and kidney problems.
Cadmium: In long term, excessive intake of it can damage kidney, liver, bone and blood.
Mercury: It can permanently damage the brain, kidneys and developing foetus.
Arsenic: It causes bladder, lung, skin, kidney and liver cancer. It harms the central and peripheral nervous systems, heart and blood vessels, and causes serious skin problems. It also may cause birth defects and reproductive problems.
Nitrates: It affects red blood cells that transport oxygen. Infants may turn bluish and develop breathing ailment.
Fluoride: It makes bone weak, making people vulnerable to arthritis and fractures.
Trihalothanes: It can lead to cancer and adverse reproductive outcome.
