Hydro-Environmental Technologies Inc
HET’s professional staff has conducted many contamination assessments including Chapter 21E site assessments for property transfer, LSD/LSD characterization, soil sampling and testing, environmental audits, hazardous waste determinations, wetland evaluations and permitting, and remediation system design.
Mr. Garcia performs hydrogeological investigations, collecting soil and groundwater samples for analysis and compiling data into detailed hydrogeological reports. He also conducts borehole logging and prepares geologic cross sections for HET projects.
Environmental Site Assessments
Environmental site assessments are a critical part of the due diligence process for commercial and residential properties. These investigations ensure that there are no contaminates in drinking water that could harm plants, animals, or people who live and work on the property.
A Phase I ESA involves a review of documents, inspections, and testing to identify potential environmental risks. This type of investigation is most often required by banks or lending institutions as part of a sales transaction or prior to listing a property for sale. It is also conducted as a part of regulatory agency oversight projects.
Phase II Environmental Site Investigations
The objective of a Phase II ESA is to determine whether a significant environmental liability exists. The scope of the investigation varies according to property location and environmental issues. Therefore, there is no such thing as a “cookie-cutter template” for Phase II Environmental Site Assessments.
Geophysical surveys are typically performed in Phase II investigations, allowing geologists to design a sampling plan for obtaining soil and groundwater samples at various depths. In addition, indoor air and sub-slab vapor sampling can be conducted where greater insight into contamination characterization is needed.
Groundwater Site Assessments
Depending on the scope of contamination identified in the Phase II ESA, it may be necessary to further profile the extent and state of the contaminants through groundwater site assessments. This can involve collecting and analyzing samples of soil, sediment, groundwater, indoor air, and/or soil vapor.
Mr. Pigott has extensive experience in UST facility closures under LDEQ closure license C-0724, site investigations (soil and groundwater) at contaminated sites, and RECAP evaluations of UST facilities. He is experienced in obtaining, reviewing, and preparing investigation plans with costs for LDEQ approval and field implementation.
Hydrogeological Assessments
HET’s staff of licensed Professional Geologists/Geoscientists is capable of conducting a variety of hydrogeological assessments and investigations. These include environmental risk assessment and remediation design and implementation for sites with contaminated groundwater.
Hydrogeology (from the Greek words for water and geology) is the branch of Earth science that deals with the distribution and movement of groundwater in porous media such as aquifers. Hydrogeology includes sub-fields of environmental geochemistry, hydrology, and geohydrology.
The primary aquifer properties are porosity and hydraulic conductivity. The latter can be indirectly measured by measuring transmissivity using a piezometer. The hydraulic conductivity is affected by the porosity through an inversely proportional relationship.
Environmental Audits
HET provides environmental audit services for clients that include financial institutions, real estate developers, oil and gas exploration companies, property managers, the Small Business Administration, and many other large and small businesses. HET personnel also provide a wide range of industrial hazardous waste determination and control services.
HET professionals have extensive experience conducting contaminant assessments and performing remediation projects for clients. These projects have included soil, sediment, and groundwater sampling, laboratory analysis, tabulation, and quality evaluation of analytical data for sites ranging in size from a single underground storage tank to large scale industrial facilities.
Hazardous Waste Determinations
HET offers hazardous waste determinations to facility owners wishing to meet regulatory requirements. HET’s team is comprised of degreed professional geoscientists with years of experience in the environmental field.
The generator of a waste must consider the materials that constitute the waste and the processes that result in its generation when determining whether the waste exhibits the characteristic characteristics of a hazardous waste. The generator must also consider the information in its MSDSs and other documentation of the processes used, referred to as “knowledge of process.”
Hazardous secondary materials generated in mineral processing must be managed by the reclaimer in a manner that is at least as protective of human health and the environment as that employed for analogous raw material.
Litigation Support
Almost all environmental court cases settle out of court, but those that do not are won by attorneys with irrefutable technical expertise and clear communication to bridge the gap between law and science. HET offers a diverse team of degreed professional geoscientists and environmental scientists to assist with litigation support services such as preparation of expert witness reports, deposition defense and trial exhibit preparation.
HET also offers indoor air quality assessments, risk characterization, occupational health and safety services, groundwater computer modeling, soil gas sampling and vapor intrusion investigations. HET maintains offices throughout the country and a 24-hour emergency response hotline.
