http://proethica.org/ontology/case/76#MWC_Public_Safety_Risk
Definition
Risk of lead leaching into drinking water above regulatory standards in MWC service area
Properties
Instance of
Active period
From the MWC vote to proceed through completion of adequate corrosion control measures
Affected parties
Engineer A
Engineer B
MWC
Public water consumers in MWC service area
Confidence
0.92
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
Risk of lead leaching into drinking water above regulatory standards in MWC service area
Terminated by
Completion of required treatment improvements or reversal of source change
Triggering event
MWC decision to change water source before required corrosion control improvements are in place, combined with the presence of old service pipes susceptible to lead leaching
Urgency level
high
Match Confidence
0.95
Match Reasoning
