A foul smell from land owned by the city of Fort Worth is wafting into Hurst.
Hurst, which sent an environmental team to investigate the putrid smell, said the stench is coming from a process that occurs in the final stages of water treatment.
A Fort Worth city contractor spread "bio solids" on land Fort Worth owns, Hurst said. Renda Environmental, a contractor that works with Fort Worth's waste water treatment plant, legally dumped sludge in a vacant field earlier this week.
A Fort Worth city spokesman said the field is approved for that use.
The contractor normally takes the bio solids to Justin.
The city of Fort Worth said it is working to fix the issue.
