Which unit is noted as providing water purification and bulk water storage?

• A. Eng Support Co
• B. 7th ESB
• C. CLB-7
• D. 1st Dental Battalion

Answer: (B)

Water purification and bulk water storage are capabilities associated with expeditionary engineering support. An Engineer Support Battalion is designed to provide that kind of forward engineering support to a MEF, including water purification assets and bulk water storage to sustain operations. The 7th Engineer Support Battalion is the unit designated to supply these capabilities, making it the best match. While the Eng Support Company is the component that carries out engineering tasks, the question is about the unit that provides this capability overall, which is the Engineer Support Battalion. The other units listed do not specialize in water purification and bulk water storage, as they serve different sustainment and medical roles.
