Significant health concerns from both natural and industrial toxins are highlighted by this research, highlighting the urgent need for remediation and legislative intervention.

The study was carried out in association with IIT Jammu. Chemical hydrology techniques were utilized in the extensive investigation to analyze groundwater samples and determine the causes of contamination and related health risks.

According to the research, industrial pollutants like zinc, lead, cobalt, nickel, and chromium as well as geogenic uranium present serious health hazards when combined with contaminated groundwater.

 

Evaluating the quality of groundwater

Researchers from IIT Jammu and the Indian Institute of Technology Mandi have examined the distribution of carcinogens in the groundwater of the Baddi-Barotiwala (BB) industrial area in Himachal Pradesh. India uses a lot of groundwater for both home and agricultural purposes.

But as a result of quickening industrialization, urbanization, and population expansion, groundwater is being used more frequently and is becoming less pure. There are serious problems with water quality in Northern India. 

Similar problems may be seen in the BB industrial area of Himachal Pradesh, where industrialization has exceeded allowable limits in contaminating groundwater with harmful metals.

 

Identifying Health Risks and Contamination Sources

Using the human health risk assessment model developed by the US Environmental Protection Agency (USEPA) for both adults and children, the study identified possible sources of contamination and assessed the carcinogenic and non-carcinogenic health hazards associated with oral consumption of contaminated groundwater.

 In addition to creating geospatial maps that illustrate metal contamination and health hazards across village boundaries, the researchers identified important metals of concern.

"Groundwater poses high health risks through oral intake, necessitating urgent remediation," stated Dr. Deepak Swami, Associate Professor, School of Civil and Environmental Engineering, IIT Mandi, in reference to the research. 

To avoid health risks, it is crucial to monitor industrial effluents for zinc, lead, nickel, and chromium. For sustainable prosperity, policies must strike a balance between industrial development and public health.

According to the study, the majority of the groundwater in the area is made of rock, primarily calcium carbonate. All samples had uniform uranium levels, and while molybdenum and uranium were found naturally, the majority of the other metals were linked to industrial sources.

 High non-carcinogenic hazards were found in the human health risk assessment for both adults and children, mainly from natural uranium and extra concerns from industrial sources of zinc, lead, cobalt, and barium. Adults were at high risk for cancer, primarily from industrial nickel and chromium.

FAQ

The study found alarmingly high levels of cancer-causing heavy metals in the groundwater of the Baddi-Barotiwala industrial area in Himachal Pradesh.

The study suggests a combination of natural and industrial sources. Natural sources include uranium, while industrial sources likely include zinc, lead, cobalt, nickel, and chromium from pollutants.

Both adults and children face health risks from consuming the contaminated water. These risks include cancer (primarily from nickel and chromium) and non-cancerous health problems (from uranium and other metals).

The study emphasizes the urgent need for remediation efforts to clean up the groundwater. Additionally, stricter regulations and monitoring of industrial effluents are crucial to prevent further contamination.

The study highlights the need for policies that promote sustainable development. This means finding ways to support industrial growth while also protecting the health and safety of the public.
