http://proethica.org/ontology/case/76#MWC_Lead_Leaching_Risk
Definition
MWC water supply transition before corrosion control safeguards are in place
Properties
Instance of
PrematureSourceTransitionState
http://proethica.org/ontology/intermediate#PrematureSourceTransitionState
Active period
From the MWC vote to proceed through completion of required corrosion control improvements
Affected parties
Engineer A
Engineer B
MWC
Public water consumers in MWC service area
Confidence
0.88
Principle Transformation
Transforms the general duty to protect public health and safety into a concrete obligation to object, document, and report when a utility proceeds with a supply change that creates foreseeable lead leaching risk in the distribution system.
Subject
MWC water supply transition before corrosion control safeguards are in place
Terminated by
Completion of corrosion control improvements sufficient to prevent lead leaching above drinking water standards, or reversal of the source change decision
Triggering event
MWC decision to change water source before the three-year evaluation and improvement timeline recommended by Engineer B could be completed
Urgency level
high

The improvements are needed prior to the change in water source to ensure that sufficient corrosion control is provided so that old service pipes in the MWC service area don't leach lead at levels in excess of drinking water standards.
the MWC voted to proceed simultaneously with the accelerated evaluation and design of needed water treatment improvements and the change in water source
