Enquiry about staying near STP

Is it bad for health?

We bought a new villa in a gated community of 200 villas in Hosur. We were not aware that the STP was very nearby, about 90 feet from the house. Now we are facing so many issues like bad smell all the time, odour in our sinks. STP unit is inside the community and maintained by the association. Is it really bad to stay near to STP units? The STP runs daily for 10 to 12 hours. A bad smell comes whenever there is wind. Please let me know if there could be any health issues beacuse of this.

Thank you,
