What Is Actually in That Water
A well-maintained swimming pool still carries microbial load. The US Centers for Disease Control and Prevention (CDC) tested public pools across multiple states and found that 58% of filter samples tested positive for E. coli, a marker of fecal contamination, even in facilities that met standard chlorine requirements. Indian public pools and water parks face an additional layer of pressure: high bather density, inconsistent chemical monitoring, and warm ambient temperatures that accelerate bacterial multiplication.
