Mr Evans, who promised to hold a meeting on the issue in October, invited speakers including regulators and researchers for the fact-finding question and answer session.
He said exploratory investigations have taken place in recent weeks.
The MP’s panel consisted of members both for and against fracking, which involves extracting underground shale gas.
Regulating bodies were represented so questions could be asked about monitoring procedures in and around Helsby.
Mr Evans said: “My view on fracking is I see the reasoning behind it as we do need to ensure we secure our energy supplies.
“However, I could not and would not agree to anything which would affect the health, safety and wellbeing of my constituents as well as their homes, businesses or our natural environment.
The panel included John Blaymires, of IGas, the company holding the area’s drilling licence.
Also present was Frodsham-born chartered surveyor Edward Cottrell and Salford University Professor Robert Jackson, who specialises sustainable engineering technologies and water and the environment.
The regulatory body representatives were Tony Almond, of the Health And Safety Executive, Greg Hodgson, of Public Health England, and Stephen Molineux, of the Environment Agency.
A spokesman for the MP said about 200 members of the public attended.
Mr Evans said: “Before this meeting I wrote to the minister to seek reassurances on matters including the decommissioning of the wells.
“Who will be responsible for their care and monitoring after they have been ‘capped off’?
“Waste water, how will this be disposed of safely?
“We also need information about the risk to road users in the area with the increase vehicular movement required to service the wells.
“Tonight’s meeting has raised some more issues, all of which have been noted down and I will take back to the minister.”
“As soon as I have a response I shall let local residents know.”
