Farm country groundwater
Around Lodi, the same alluvial aquifers that supply Stockton sit under a patchwork of vineyards and orchards. Decades of farming leave their mark on shallow groundwater: a USGS study in the eastern San Joaquin Valley found nitrate above the drinking-water limit reaching more than 20 meters below the water table, and the banned fumigant DBCP still above its limit nearly 40 meters down, more than 25 years after it was last used.
What that means for your well
It doesn’t mean your water is bad. It means a test should cover more than bacteria. For a Lodi-area well, ask a state-certified lab about nitrate, arsenic and, if the property has a long farming history, the fumigants 1,2,3-TCP and DBCP. Deeper wells with a good sanitary seal are generally better protected than shallow ones.
Pumps that work hard
Many properties here run more than a house off one well: a shop, livestock water, landscape irrigation. That puts real hours on a pump and pressure tank. A correctly sized pressure tank and a pump-saver or constant-pressure control can add years to the system.
Permits
Lodi-area wells outside the city fall under San Joaquin County Environmental Health, which requires a permit for new wells, pump replacements and well destruction. Unused wells have to be properly destroyed, which also protects the aquifer everyone in the area shares.

Lodi questions
Asked and answered.
Should I test my Lodi-area well for farm chemicals?
If the property is or was farmed, it’s worth asking the lab about 1,2,3-TCP and DBCP along with nitrate, arsenic and bacteria. USGS found DBCP persisting in eastern San Joaquin Valley groundwater decades after its ban, and 1,2,3-TCP at high levels in about 9 percent of domestic groundwater near Stockton. A single test tells you where you stand.
My pump runs the house, the shop and the drip lines. Is that too much?
Not if the pump, tank and controls are sized for it. Problems start when a pump meant for a house is asked to run irrigation too: it cycles constantly and wears out early. We look at the well’s yield and your real demand, and size the pump, pressure tank and controls to match.
What do I do with an old well I no longer use?
It has to be properly destroyed under a San Joaquin County permit, not just capped. An open or poorly sealed well is a direct path for surface contamination into the aquifer and a physical hazard. As a C-57 contractor we can handle the permit and the destruction.

No water? Check the well pump’s breaker. If it trips again, leave it off and call. Never open the pressure switch, control box or wellhead wiring: they’re live at 240 volts. Water suddenly changed color, smell or taste, or the well flooded? Don’t drink it until it’s tested; use bottled water. Smell gas? Leave the building and call the gas utility or 911 from outside.
