# '''IPZ‐2''':  This area is developed by utilizing both hydrodynamic modelling and a time-of-travel calculation within overland pathways (natural and human-made - i.e. rivers, creeks, swales, storm sewers, etc.) that ultimately lead to and discharge near the municipalities intake(s). Includes both the on and offshore areas where overland flowing water that may be polluted with a concentration of a given number of contaminants would be able to reach the municipal intake within approximately two (2) hours. The 2 hour mark is set as the minimum amount of time to allow municipal water system operators to address a potential contamination concern.

# '''IPZ‐3''': This area lies outside of IPZ-1 and IPZ-2 and as such contaminants likely could only reach the intake pipe during and/or after a major rainfall/storm event. The size and shape of an IPZ-3 zone is based on associated lakes, streams and other humanmade conveyances that could contribute excess overland flow during an event. <br>
