When the seismic wave passes through water ions it disrupts the bonds formed with minerals, leaving a recordable electrical signature. Data is collected via two metal pins hammered into the ground, which are connected to a smartphone with a company electro-seismic App.
The Havelock North data was processed in South Africa, where company founder Dr Michael du Preez identified areas of connectivity between water sources and areas of potential interest or concern.
"I genuinely hope it adds value," Mr McKendry said.
"It is pretty clear to see what is going on."
While the aquifer under Brookvale Rd is shallow, in some areas 5 metres below the surface, data was processed to 150m deep along a 750m stretch of Brookvale Rd and surrounding area.
He said the model showed clear underground inter-connectivity "but I certainly wouldn't be saying there is any inter-connectivity to the surface".
He said most aquifer maps relied on well logs.
"I am not knocking that method, but they only have data to the bottom of the well and a 1sq m view. With this you get a much better view of a much wider and deeper area.
He said the Hawke's Bay Regional Council was not surprised at the connectivity in the map and referred to it as an aquitard, a contained strata of water.
He would like to map the area properly, especially the creek running nearby.
"Most creeks run on a fault line, that's how they form. You get a shake like we have just had and the creek will find soft areas, where the shake came, and make its way there and can go very deep."
He said while he wouldn't mind picking up some Hawke's Bay clients "we are just trying to show people what the aquifers do look like".
"We are doing a lot of work in the Bay of Plenty, Waikato and North Auckland."
The Havelock North aquifer was closed after the gastro outbreak but will likely re-open for public supply during the high-demand summer months, with water treatment in place.
