“A well is a conduit for anything on the surface to get down to the groundwater table. It’s a straight shot.” Barry Marcus is the Supervising Environmental Specialist with the Sacramento County Department of Environmental Management (EMD) and he’s concerned about innocuous looking holes in the ground all over the city. These wells, all dug before 1950, aren’t on any maps but could allow chemicals and bacteria into our drinking water supply.
EMD engineers say nearly half of the people who live in Sacramento County rely upon groundwater for their daily needs. The Pocket and Greenhaven neighborhoods were, until the 1980′s, largely farmland and Marcus says wells could be anywhere. “Typically it is a steel pipe that sticks out of the ground. Usually larger than four inches in diameter. It may or may not have a steel plate welded over the top of it. Occasionally it’s surrounded by a concrete apron. Which could be a small circle or a square or a rectangle.”

What lies beneath?
Marcus admits inspectors with EMD haven’t yet been out to the Pocket area but they will send someone out if you want to report a possible well. Marcus says it’s important to note well heads could be partially buried. If you know that a windmill once existed on your property chances are good the windmill powered a well. Marcus also advises, “If someone has an area in their yard that keeps sinking and they don’t really know why it keeps sinking and they keep having to put dirt in that area, it’s possible there’s a well-casing there.”
Why is EMD so worried about forgotten wells in our community? Many wells are so old, says Marcus, they may have deteriorated and now allow runoff water with bacteria, pesticides, herbicides and other pollutants to flow right into the groundwater supply. That groundwater is just under the surface for homes next to the Sacramento River levee and only five feet under the dirt in neighborhoods near the edges of the Pocket area. The water table is only up to 20 feet deep through most of our neighborhoods and about forty feet deep next to I-5.
There is another concern that Marcus recounts as he tells the story of a Land Park grandmother who found her two-year old granddaughter playing near an 18-inch wide well she didn’t know was there. The girl didn’t fall in but Marcus says she easily could have fit through the loosely covered hole. In fact, earlier this year two dogs fell into a twenty-foot well near Franklin Boulevard.
