CAPE-APTIM JV1 LLC, a Norcross, Georgia, environmental remediation joint venture, received a $200 million Army contract to clean up the Standard Chlorine of Delaware Superfund Site, as announced on war.gov.

The cost-plus-fixed-fee, indefinite-delivery/indefinite-quantity award carries an estimated completion date of July 26, 2031, according to war.gov. The company submitted one of three offers solicited over the internet, according to war.gov.

“CAPE-APTIM looks forward to executing this contract with the highest proven standards of safety, quality, and performance that protect human health and the environment,” the company said in a February statement announcing an earlier Navy award, according to aptim.com.

The deal marks the first contract recorded for CAPE-APTIM JV1 LLC and sets the company’s 2026 benchmark at $200 million. It ranks as the second Department of Defense contract awarded in Georgia during 2026, one of five issued nationwide on July 27, 2026.

The joint venture pairs Cape Environmental Management Inc., a minority-owned small business in Norcross with three decades of remediation experience, and APTIM, its mentor under the Small Business Administration’s Mentor-Protégé program, according to aptim.com. The two firms specialize in remedial and removal actions, site characterization, and long-term operations at federally regulated sites, according to aptim.com.

An indefinite-delivery/indefinite-quantity contract sets a ceiling value while leaving specific work orders, locations, and funding for later. The U.S. Army Corps of Engineers in Philadelphia will determine each task order over the five-year term, according to war.gov. That structure lets the government pace spending against remediation needs rather than commit the full sum at signing.

Who benefits is straightforward. The contractor gains a large, multiyear revenue stream, and residents near the Delaware site stand to gain reduced exposure to legacy chemical contamination. Taxpayers carry the cost, and cost-plus-fixed-fee terms place the risk of overruns largely on the government.

Superfund cleanups touch daily life for people living near industrial legacy sites. Contaminated groundwater and soil can affect drinking water, property values, and public health. Federal remediation aims to restore land for safer use.

This kind of award has happened before for the same firms. CAPE-APTIM JV1 won a $95 million Navy remedial action contract in February 2026 to support installations across the Naval Facilities Engineering Systems Command Atlantic region, with work expected to finish by January 2031, according to aptim.com. The new Army award more than doubles that figure and extends the venture’s federal cleanup portfolio.

The U.S. Army Corps of Engineers in Philadelphia will decide each task order under the contract. A date for the first delivery order has not been announced.

Delaware’s chemical corridor has drawn federal cleanup attention for decades, as happened before at neighboring sites. The Standard Chlorine of Delaware plant near Delaware City processed chlorinated compounds for years before contamination drove it onto the National Priorities List. Regulators documented tainted soil, groundwater, and wetlands across the property. The latest award signals that remediation at the long-troubled site remains a multiyear commitment for the contractors now charged with restoring it.

This contract represents the 1st contract awarded to CAPE-APTIM JV1 LLC, in 2026, bringing the company’s total contract value for the year to $200,000,000. It is also the 2nd Department of Defense contract awarded in Georgia during 2026. Because this is the first award to CAPE-APTIM JV1 LLC recorded in the database, it establishes the company’s initial benchmark within the Army portfolio. Specifically, it falls between the 2026 Army portfolio’s year-to-date minimum of $35,000,000 and maximum of $257,886,133. Overall, this award was announced among 5 Department of Defense contracts issued nationwide on July 27, 2026.
