Utilities vary chemicals based on conditions

The water that comes out of your faucet in Bargersville doesn’t look any different from the water in Greenwood, but the chemicals used to clean that water aren’t the same.

Two town water departments and a statewide water company provide water for residents in Johnson County, and each agency uses different chemicals to purify the water.

The agencies have used mostly the same water treatments for decades, basing the chemicals they use on what natural chemicals already are found in their water and the type of pipes the water runs through. But one local town recently added a temporary chemical to better disinfect its water, because more natural ammonia was in the water than usual.

Water department officials say the chemicals are meant to keep the water clean, and residents likely won’t notice a difference in the taste or smell of water in one community compared with water somewhere else.
