John walked towards the Mississippi

[alpacinou]

Is this correct and natural?

John walked towards the Mississippi, feeling the soft soil swallowing his steps. As he got closer, he felt the acrid smell of sewage wafting from the surface of the water fill his nose. The river along with all the filth they'd dump into it flowed soundlessly in the humid night. He jumped in the water, his hands motionless, plunging deeper and deeper into the abyss.

 

[probus]

Sewage smells fetid or putrid, not acrid. Look up acrid in a good dictionary.

Jumped into not in.

 

[Charlie Bernstein]

In the US, "jumped in the water" is fine.

Examples:

- In his song "I'm Tore Down," Freddie King wrote:

Well, I went to the river to jump in.
My baby showed up and said, "I will tell you when."

- In his song "Goodnight, Irene," Huddy "Leadbelly" Ledbetter wrote:

Sometimes I live in the country, sometimes I live in the town,
Sometimes I take a great notion to jump in the river and drown.
