Architecture

The employment outlook for environmental engineers is excellent. The field is projected to grow 15% from 2012 to 2022, which is faster than the average for all occupations. Some growth will be fueled by the need for water reclamation projects that increase water supplies, especially in Western states.

I don't think you can get any college through JoSAA. Try for private college or state government college.
