Ammonia Pollution in Yamuna
Context
A political debate has emerged between the Haryana and Delhi state governments regarding the persistent high ammonia pollution in the Yamuna River.
Relevance of the Topic
- Prelims: Questions may focus on the impact and sources of pollutants.
- Mains: Detailed questions can address the impact of ammonia, challenges in controlling Yamuna pollution, and suggestive measures to tackle the issue.
Ammonia Pollution in Yamuna
- Ammonia is a nitrogen-hydrogen based inorganic compound (NH3).
- The ammonia limit in drinking water is set at 0.5 ppm by the Bureau of Indian Standards.
- Yamuna’s ammonia concentration was recorded at 2.3 ppm at the Wazirabad treatment plant.
Impacts of Ammonia Pollution
Water Supply Disruptions
- High ammonia levels force water treatment plants to reduce or halt operations, e.g., 40% reduction in water production at Wazirabad.
Health Risks
- Toxicity: Ammonia reacts with chlorine during treatment, producing harmful byproducts.
- Respiratory issues: Ammonia fumes can cause breathing difficulties.
- Skin rashes and eye irritation are common.
- Long-term exposure leads to neurological effects like headaches, dizziness, and confusion.
Ecosystem Degradation
- Algal bloom due to ammonia, which depletes dissolved oxygen.
- Biodiversity loss as ammonia makes water bodies uninhabitable for sensitive aquatic species.
Sources of Ammonia Pollution
Industrial Effluents
- Factories discharge untreated or partially treated waste containing ammonia, particularly from the industrial zones of Haryana and Delhi.
Sewage and Waste Discharge
- Untreated sewage contributes to ammonia formation as organic matter breaks down. Delhi releases 58% of untreated wastewater into the Yamuna.
Agricultural Run-off
- Fertilizers containing nitrogen compounds break down into ammonia, contributing to pollution, especially from Punjab and Haryana due to excessive fertilizer use.
Decomposing Organic Waste
- Dead plants and animals in stagnant water increase ammonia levels.
Reduced River Flow
- Low water flow, especially in dry seasons, concentrates pollutants, worsening ammonia pollution.
- The National Institute of Hydrology (NIH) report highlighted that upstream water withdrawals significantly reduce the flow through Delhi, exacerbating pollution and harming aquatic life.
Challenges in Controlling Pollution in Yamuna
Upstream Pollution
- States like Haryana and Punjab contribute to pollution, and it is beyond Delhi’s jurisdiction to take action against them.
Limited Sewage Treatment
- Delhi generates 3200 million liters of sewage daily, but treatment plants can only handle 2600 MLD.
Limited Technology Capacity
- Delhi’s water treatment plants are not equipped to handle ammonia levels above 1 ppm, causing frequent shutdowns.
Infrastructure Development Delays
- Delays in upgrading infrastructure, such as interceptor drain projects, hinder efforts to divert untreated sewage and achieve pollution reduction targets.
Ineffective Regulations
- Lax industrial regulations and improper implementation, especially in small industries, leave room for violations that lead to pollution.
Lack of Coordination
- Agencies like Delhi Jal Board (DJB), CPCB, and DPCC often overlap in roles, lacking effective coordination in tackling the issue.
