The Department of Homeland Security stored $28 million worth of radio equipment while its divisions were facing critical shortages of such equipment, according to a watchdog report released this week.

The issue illustrated problems with the agency’s inventory practices and showed that it lacked the necessary processes to spend wisely on new radio-network resources, the report said. The agency devoted $3 billion toward such upgrades in 2012.

“DHS risks wasting taxpayer funds on equipment purchases and radio system investments that are not needed, sustainable, supportable or affordable,” deputy DHS inspector general Charles Edwards said in his executive summary.

Edwards recommended that the agency create a department-wide inventory and establish a single point of accountability to oversee the portfolio. DHS management agreed with the suggestions and took steps to follow them.

“DHS’ planned corrective action satisfies the intent of the recommendation and is considered resolved,” the report said.
