LDD

What LDD does

LDD Advanced Technologies Ltd. is an Israel-based environmental engineering firm founded in 1989 by Dr. Rapi Mandelbaum, providing end-to-end soil and groundwater remediation services across site characterization, risk assessment, remediation design and execution, regulatory liaison, and post-remediation monitoring. The company operates a broad technology portfolio spanning in-situ (bio-augmentation, chemical oxidation/reduction, air sparging, thermal desorption), on-site (biological treatment via subsidiary BIOSOIL), and ex-situ treatment methods, with additional differentiated capabilities including PFAS thermal destruction (via partnership with Haemers Technologies), nano-bubble water treatment (Nano+/FiltoPlex), and advanced AMS Direct Push drilling (via subsidiary Bioterra).

The business operates a project-based B2B professional services model, generating revenue through multi-year contracts with government ministries (Ministry of Environmental Protection, Ministry of Defense, Water Authority, Tel Aviv Municipality), defense industry clients (Rafael, IDF bases), large industrial and energy operators (Teva, Eshkol Power Station, KSA/EAPC pipeline), public transit (Egged, Dan), and real estate developers (Shikun & Binui, Hila Group, RAMI urban renewal). Pricing is custom-quoted per project, and LDD notably offers Fixed-Cost/Fixed-Timeline remediation commitments to real estate developers. The firm has four wholly-owned subsidiaries — LDDWJ (groundwater dewatering JV with UK-based WJ Groundwater), BIOSOIL (licensed biological treatment facility operating 17+ years), Bioterra (environmental drilling), and Nano+ (nano-bubble systems) — and exclusive representation agreements with several international laboratories (Element-Jones, Beacon, TestAmerica, SIREM).

LDD is the self-described leading remediation firm in Israel, employing 70+ staff across parent and subsidiaries, with prior international project execution in Jordan, Honduras, Ethiopia, Tanzania, and Sri Lanka. The company is privately held with no disclosed institutional investors, and its primary go-to-market relies on direct enterprise field sales, public tender participation, and professional referrals from law firms and environmental consultants.

Functional benefit

Products and services

• Environmental Consulting Services Strategic environmental consulting services including Israeli RBCA (Risk-Based Corrective Action) surveys, environmental due diligence for transactions, expert testimony for legal proceedings, feasibility studies for real estate projects, accompaniment through building permit processes, and EHS environmental audits.
• Soil Surveys Comprehensive subsurface mapping to identify contaminants, determine soil structure, and assess pollution levels in accordance with regulatory standards. Determines contamination type, depth, concentration, and vertical/horizontal spread for site characterization.
• Groundwater Surveys Professional hydrogeological procedures to characterize water quality, water table depth, and flow directions in aquifers for environmental management, plume mapping, and remediation planning.
• Soil Gas Treatment and Vapor Intrusion Prevention Sub-slab ventilation systems, vapor barriers, and soil gas treatment to prevent hazardous gas intrusion into buildings at contaminated sites.
• Groundwater Remediation Hydrogeological-engineering procedures to treat contaminants in aquifers and prevent their spread, using pump-and-treat, chemical treatment, bioremediation (including bio-augmentation), air sparging, and SVE (soil vapor extraction) techniques.
• In-Situ Remediation Below-surface treatment of contaminated soils and groundwater without excavation, using controlled injection of materials, gases, or energy directly into the subsurface.
• On-Site Soil Remediation Treatment of contaminated soil within site boundaries rather than transport to off-site facilities, using biological, physical, and chemical methods. Provides 30-50% cost savings versus excavation-and-landfill approaches and avoids logistics and security risks of moving contaminated soil.
• Ex-Situ Soil Remediation Excavation and transport of contaminated soil to dedicated treatment facilities — primarily BIOSOIL's licensed biological treatment facility in Kibbutz Nitzan — for controlled processes to neutralize contaminants.
• Thermal Treatment Thermal desorption for treating contaminated soils, effective for volatile organic compounds, semi-volatile compounds, petroleum hydrocarbons, pesticides, and mercury. Includes in-situ thermal treatment via heated wells and ex-situ thermal treatment via partnership with Haemers Technologies (Belgium) capable of completely destroying PFAS ('forever chemicals') rather than transferring them to filters.
• Injections (ISCO, ISCR, Bio-Augmentation) Injection services for in-situ remediation including chemical oxidation (ISCO), chemical reduction (ISCR), and bio-augmentation treatments injected directly into contaminated aquifers.
• GIS Mapping Geographic Information System mapping including processing and analysis of spatial phenomena at national, regional, and site-specific levels for site characterization, plume mapping, and regulatory reporting.
• Groundwater Dewatering Controlled groundwater level management through pumping and well systems to support construction and infrastructure projects, delivered through the LDDWJ joint venture with WJ Groundwater (UK).
• Laboratory Services for Environmental Analysis Environmental analysis for air, soil, and groundwater through partnerships with internationally accredited laboratories including Element-Jones, Beacon Environmental, TestAmerica, and SIREM, providing ISO 17025 accreditation under Israeli, EU (EEA), and US (EPA) standards.

Quantifiable outcome

• Reduced TCE contamination by 97% within 6 months using bio-augmentation without disrupting facility operations
