Water TDS levels in vizag

Im looking for a water purifier, but im so confused. Going for RO is just overkill if the TDS is below 500. When i googled. I didnt get a solid answer. Some influencers telling to go for RO, if the area is industrialised. Since vizag is heavily industrialized, should i go for RO? Or should i believe in our muncipalities that they keep the TDS below 500 and go for UF + UV. Which purifiers are u using and what do u suggest? Note : We also use bore water
