Delhi Chief Minister Arvind Kejriwal submitted his formal reply to the Election Commission (EC) regarding his controversial remarks about the water quality in the Yamuna. The EC had earlier issued a notice to Kejriwal, seeking an explanation for his statement about the water being "poison mixed" with high ammonia levels. Kejriwal, along with Delhi Chief Minister Atishi and Punjab Chief Minister Bhagwant Mann, appeared at the EC office in New Delhi to present his response.

In his letter, Kejriwal clarified that his comments were focused on the rising ammonia contamination levels in raw water supplied to Delhi from Haryana. He stressed that his reference to the water being "poisoned" was solely about the "unprecedented and dangerously high levels of ammonia contamination" that had reached alarming levels, peaking at 7 parts per million (ppm) in January, and were a serious health risk to the public.

Kejriwal explained that he had made these remarks after several attempts to engage with the Haryana government, which he claimed failed to take any corrective action. The Delhi CM alleged that the Haryana government had intentionally sent contaminated water to Delhi in an attempt to influence the ongoing elections, accusing them of creating a "manufactured crisis" to undermine the AAP government’s image.

The AAP leader further called for a criminal investigation into Haryana’s actions, accusing its chief minister of deliberately worsening the situation for political gains ahead of the Delhi Assembly elections. Kejriwal also reiterated his claims that the situation had been manipulated to tarnish the image of the AAP government.

Before arriving at the EC office, Kejriwal addressed reporters, alleging that the poll body’s second notice suggested that the EC had already decided on a course of action. He claimed the EC was "shooting the messenger" for raising the issue and accused it of political maneuvering.

Kejriwal also congratulated the people of Delhi for their resilience, stating that ammonia levels, which were as high as 7 ppm between January 26-27, had now dropped to 2.1 ppm. The AAP leader emphasized that his actions had helped avert a manufactured water crisis that could have adversely affected the elections.

The EC had issued two notices to Kejriwal, seeking specific details about the claims of contamination and the methods used by the Delhi Jal Board to detect the "poison" in the water. Kejriwal was asked to provide these details by 11 am on Friday or face further action.
