Customs and Border Protection has ordered contractors building President Donald Trump's second border wall in New Mexico to stop drilling new wells after ranchers warned that unmonitored groundwater pumping to produce concrete threatened their livestock amid severe drought (The Guardian). The stop-drilling directive, confirmed by a CBP spokesperson speaking to the Associated Press, applies to well-drilling operations feeding concrete production for the barrier construction that CBP oversees (Paradise Post).

The halt followed escalating complaints from local landowners. At a July public meeting, ranchers reported unmonitored tapping of border aquifers that threatened the water for those nearby. Cattle rancher Russell Johnson, whose property runs along the border, raised the issue after discovering an industrial well on land he leases for grazing; drilling crews told him the well would pump 300 gallons per minute. By contrast, Johnson noted that the roughly 12 wells across his ranch pump between three and seven gallons per minute. He warned the situation could put some people out of business, including himself (The Guardian).

State regulators corroborated the ranchers' concerns. New Mexico's office of the state engineer counted at least six wells under development along the border, none of which had obtained the permits required by state law before drilling or pumping could begin. Staff from that office visited two wells in July and reported they were pumping 200 gallons per minute. Under New Mexico law, all non-tribal wells in the state, whether drilled on state or federal land, must secure permits from the state engineer before construction or water extraction can proceed (The Guardian). The state engineer's office is responsible for regulating the construction and abandonment of wells and the licensing of well drillers statewide (New Mexico OSE).

The aquifers in question were already depleted before federal drilling began, a condition that predates the current construction surge (WBUR). CBP stated in a formal release that water from the drilled wells was needed to make concrete for the border wall construction (Paradise Post). The agency also said it is committed to working collaboratively with local landowners to ensure that construction activities do not adversely impact their water needs (The Guardian).

The border barriers under construction span four states and have received over $46 billion in federal funding. The project currently underway in New Mexico is Trump's second border wall (The Guardian; Newsday; Daily Courier).

The broader context here involves a collision of federal infrastructure imperatives with state-level natural resource governance. CBP, operating under federal authority, initiated well drilling to supply concrete for a multibillion-dollar barrier system. The New Mexico Office of the State Engineer, operating under state statute, requires permits for all non-tribal wells regardless of whether the underlying land is federally or state administered. The six wells identified by the state engineer were developed without those permits, placing the federal contractors in a posture of noncompliance with state water law. The extraction rates documented by state inspectors and by ranchers themselves point to a significant drawdown per well relative to existing agricultural usage. Russell Johnson's ranch wells pump three to seven gallons per minute; the industrial well he encountered was slated for 300 gallons per minute, and the two wells inspected by state staff were each pumping 200 gallons per minute. That differential, applied across multiple unpermitted wells tapping an already depleted aquifer system during severe drought, forms the technical and legal basis for the stop order.

For practitioners tracking federal-state jurisdictional friction, the case is instructive. The federal government can construct border barriers on federal land, but the extraction of state groundwater resources for that construction falls within the regulatory perimeter of the state engineer's office in New Mexico. CBP's collaborative posture in its public statement signals an institutional recognition that proceeding over state objections would invite litigation and regulatory escalation. The order to halt drilling is, at its core, a concession that federal infrastructure timelines are contingent on state water permitting regimes, not insulated from them.
