Preventing product loss, mishandling or leakage can be achieved through proper tank installation and effective operational and maintenance practices. At GZA, our goal is to help clients implement tank management programs that prevent adverse events, promote continual compliance, and extend active tank life.

GZA’s consulting services address all regulatory aspects of tank life including monitoring, inventory control, testing, installation, design and removal. Our response to inventory management requirements can include recording and reconciling product inflow and outflow, and providing necessary status reports.

Planning, Design, and Installation of New Tanks. Our designs vary according to specific site conditions and client cost considerations. As a result, our staff develops designs for new tank installations that often require innovative approaches. Beyond design, we offer construction management services for installations. GZA has experience installing double-wall tanks and secondary containment systems, and we also perform primary and secondary tank-shell testing, in-tank leak detection, and assessment of pumping and product dispensing systems for new installations. Our technicians also have experience anchoring tanks in areas having high groundwater levels.

Remediation of Adverse Tank Events. Handling tank contamination, from excavation to disposal, is subject to specific regulatory requirements. Knowing the remediation and disposal options as they apply to those regulations can directly impact costs. GZA tailors its services to achieve the most beneficial, cost-efficient results. Those services can range from environmental monitoring to geotechnical engineering including excavation, compaction and fill testing. For temporary or permanent tank closures, GZA complies with regulatory-approved procedures for product removal, sludge disposal, capping, and venting.

When necessary, GZA performs soil remediation utilizing fixation, containment, and soil vapor extraction. For groundwater recovery and treatment, various techniques such as air sparing, countercurrent aeration or liquid phase carbon removal are used.
