PHOENIX (AP) — The Trump administration has ordered construction crews on a border wall to stop drilling wells in drought-stricken New Mexico after ranchers said pumping groundwater needed to make concrete could threaten their livestock. This was reported by Qazaqyia.kz citing Associated Press.

The order comes as crews across the southern border race to complete one of President Donald Trump's highest domestic priorities — barriers that span four states and received over $46 billion in federal funding. Controversies have sprouted up in Texas and California, with border-town residents and environmentalists reporting a wide variety of issues with construction.

U.S. Customs and Border Protection, which oversees border wall construction, has said water is needed to make concrete for roads, wall construction and dust suppression. Cattle ranchers in the area say the drought has already forced them to reduce their herd size.

"It would put us in an immediate catastrophe and having to do something with our livestock. I mean, it could potentially put some people out of business, us included," said Russell Johnson, a cattle rancher whose property runs along the border.

Johnson raised the issue at a public meeting in July after noticing an industrial well, which drilling crews told him would pump 300 gallons a minute, on land he leases for grazing. Johnson has roughly 12 wells across his ranch, which pump between three and seven gallons a minute.

A spokesperson for CBP said on Monday that border wall contractors in New Mexico have been instructed to stop drilling new wells, but did not comment on whether the wells already drilled could be pumped. The agency said they would collaborate with New Mexico and the U.S. Department of Agriculture to develop a groundwater strategy.

"CBP is committed to working collaboratively with local landowners to ensure that construction activities do not adversely impact their water needs," read the statement.

The federal contractors building the wall in New Mexico — Caddell Construction Co. and Fisher Industries — did not respond to emails or phone calls seeking comment. Messages left with receptionists for Barnard Construction and Spencer Construction Co., the contractors building near Johnson's ranch, were not immediately returned.

The New Mexico Office of the State Engineer, which monitors and approves wells across the state, said staff have counted eight wells drilled without the office's permission along the southern border, but cautioned there could be more. Staff visited two wells in July and reported they were pumping 200 gallons per minute.

"All non-tribal wells in New Mexico, whether they are drilled on state or federal land, must have permits from the state engineer before they can be drilled or water can be pumped from them," the Office of the State Engineer said.
