Loureiro services

Loureiro has worked on projects as diverse as our client base. Contaminated properties resulting from poor historic practices are typically a major financial burden to our clients. We have a track record of cost-effectively defining the nature and extent of contamination, quantifying risk, and developing the solution that best fits the site. Our experience covers a vast array of contaminants, environmental media and settings. Our team of engineers, geologists, hydrogeologists, chemists, environmental specialists and technicians will explain the challenges in readily understandable terms, always maintaining our “can do” attitude.

Loureiro is committed to solving our client’s engineering challenges with cost-effective and practical solutions, while delivering an ecologically responsible and sustainable development. Today’s projects require finding a balance between maximizing a site’s development potential and sustaining the local environment through innovative technical solutions. Our services range in scope from preparation of permit applications for a development project to the preparation of detailed design plans and specifications for various municipal, industrial and private-sector improvement projects, for a variety of clients. Our team will guide you from conceptual planning and detailed design to construction close-out of the simplest to most complex projects you may have.

This manufacturer had a process that involved abrasive tumbling, alkaline cleaning and acid etching of stainless steel parts. Loureiro designed and installed an automated batch treatment system to neutralize the wastewater generated from these processes. After an economic analysis, the decision was made to provide a simple batch system not requiring a full-time operator. Loureiro prepared the discharge permit application for submittal to the Connecticut DEEP. Collection sumps were designed for each of the wastewater generating locations along with a central collection tank. The treatment sequence was initiated by a level control, which started metering pumps to provide either sodium hydroxide or sulfuric acid to maintain pH.Loureiro provided the equipment installation and connection to the sanitary sewer and also provided system start-up supervision and operator training. Operating and maintenance manuals were prepared for both the operating personnel and the Connecticut DEEP.

Loureiro was retained to perform the remediation of wetlands/watercourses that had been impacted with polychlorinated biphenyls (PCBs), metals, petroleum hydrocarbons, and various other organic compounds. The work included dredging activities within approximately three acres of brook, pond, and swamp, the installation of a geosynthetic and earthen cap within the brook and pond, the construction of a geocomposite cap along the banks of the brook and pond, and the reconstruction of several hundred feet of a 4-lane road. The project was completed in two phases and ultimately resulted in the excavation and offsite disposal of nearly 90,000 tons of PCB-impacted materials.

Loureiro provides on-call services for the characterization of building materials generated during facility modifications at a large aerospace manufacturing plant in Connecticut. Services include the collection of representative samples of various media including concrete floors, walkways, asphalt and wooden floor blocks. Sample analysis is selected based on an assessment of current and historic industrial activities which have occurred in the area where the construction materials are being generated. Following an evaluation of analytical results Loureiro arranges for reuse, recycling and or disposal of the materials. Arrangements includes profiling, transportation and contracting the final management of the waste streams.
