I have a aquifer well. Had it checkd for potential health issues per county rules. Its about 7 yrs old. Its over 100ft deep. County requires a well be no less then 75ft deep. Had some sand issues one summer, but never once has the well company or county said anything about shocking it. Never heard that term even on my parents property.
My well water is run thru pre filters for sand, then osmosis filters for iron,then filtered at kitchen sink to remove salt ect.
Give me my freedom,guns and money. You can keep the change.
