** If said mitigation/treatment protocol needs to be amended and time allows a mitigation system can be installed to limit the movement of said chemical to the well or the water treatment process at the receiving Water Treatment Plant (WTP) can be modified to sufficiently decrease the concentrations being received

When it comes to WHPAs once size does not fit all, there are multiple zones that extend in an irregular radius around a well to ensure adequate protection of the source water protection area, which is divided into five (5) zones based upon contaminant travel time within groundwater sources:

{{textbox|When it comes to WHPAs once size does not fit all, there are multiple zones that extend in an irregular radius around a well to ensure adequate protection of the source water protection area, which is divided into five (5) zones based upon contaminant travel time within groundwater sources:

# '''WHPA-A''' – an area of 100 metre radius around the wellhead

# '''WHPA-A''' – an area of 100 metre radius around the wellhead

# '''WHPA-B''' – the zone through which it takes groundwater to travel between two years and the 100 metre distance

# '''WHPA-B''' – the zone through which it takes groundwater to travel between two years and the 100 metre distance

# '''WHPA-C''' – the zone through which it takes groundwater to travel between five and two years

# '''WHPA-C''' – the zone through which it takes groundwater to travel between five and two years

# '''WHPA-D''' – the zone through which it takes groundwater to travel between 25 and five years

# '''WHPA-D''' – the zone through which it takes groundwater to travel between 25 and five years

# '''WHPA-E''' – the area on ground surface through which surface water flows in two hours to a point close to the well. This wellhead protection area is only delineated when studies have shown that surface water can relatively easily seep through the soil and impact the quality of the water at the well. This situation is known as groundwater under the direct influence of surface water, or a GUDI well}} (Halton-Hamilton Source Protection Region, 2010<ref>Halton-Hamilton Source Protection Region. 2010.
