Hydrant Flushing Underway in Middletown, Portsmouth

Water Being Flushed to Allow New Source Water into System

NEWPORT, R.I. (THURSDAY, JULY 8, 2021)

The Newport Water Division, which supplies drinking
water to the majority of Aquidneck Island, is currently performing hydrant flushing after receiving
reports of discolored water in parts of Middletown and Portsmouth.

After investigating the reports, Newport Water Division personnel determined that water being
drawn from the Lawton Valley Reservoir in Portsmouth was displaying increased level of manganese,
a naturally occurring mineral that can affect the taste, odor, and color in drinking water.

The service area for the Lawton Valley Plant includes the majority of Middletown and the Portsmouth
Water & Fire District, however does not supply Newport customers.

Upon determining the cause, Newport Water began drawing from the Watson Reservoir in Little
Compton and the treatment has greatly improved. For the past two days, hydrant flushing has been
used to expedite the discharge of any problem water still in the system’s water storage tanks and
introduce the improved water into circulation.

Manganese is mineral and is a Secondary Drinking Water Standard. Secondary Drinking Water
Standards established by EPA are non-enforceable guidelines regarding contaminants that may
cause aesthetic effects such as taste, odor or color in drinking water.

Newport Water apologizes for the inconvenience and is working to diligently to correct the situation.
