Frequently Asked Questions

  • What is a Phase 1 Environmental Site Assessment (ESA)?

    A Phase 1 Environmental Site Assessment (ESA) is a comprehensive evaluation of a property’s history and environmental condition, designed to identify potential or existing environmental contamination risks. It typically includes a review of historical records, site inspections, and interviews with owners and occupants. This assessment is crucial for property transactions, particularly for buyers, sellers, and lenders, to ensure compliance with environmental regulations and to avoid liabilities related to contamination.

  • What is involved in commercial and residential underground tank removal?

    Underground tank removal involves excavating and removing storage tanks that are no longer in use or pose environmental risks due to leakage. For both residential and commercial properties, this process includes safely excavating the tank, cleaning out any remaining fuel or contaminants, and testing the surrounding soil for contamination. In Raleigh, NC, we follow strict guidelines to ensure that tank removal is handled safely, preventing any future environmental hazards.

  • How does environmental remediation work after contamination is discovered?

    Environmental remediation involves identifying and cleaning up contamination from soil, water, or air to ensure the environment is safe and compliant with regulations. The process typically begins with an assessment to determine the extent of contamination, followed by methods such as soil removal, water treatment, or chemical stabilization to eliminate pollutants. We use innovative technologies and industry-best practices to restore contaminated sites efficiently and cost-effectively.

  • What is Total Petroleum Hydrocarbons (TPH) testing, and when is it needed?

    Total Petroleum Hydrocarbons (TPH) testing is used to measure petroleum contamination levels in soil and water. It is necessary for properties with underground tanks, or where oil spills or leaks have occurred, to assess the extent of contamination. TPH testing provides critical data for developing effective remediation plans. Cohesion Inc. offers TPH testing for both residential and commercial properties, ensuring compliance with local and federal regulations.

  • Why are heating oil tank inspections important for homeowners?

    Regular oil tank inspections are essential to ensure that tanks are functioning correctly and are not at risk of leaking. If heating oil tanks corrode or develop leaks, they can contaminate soil and groundwater, leading to costly cleanups. Our inspections help homeowners detect potential issues early, ensuring the safe operation of tanks and preventing environmental damage.

  • What is the process for well abandonment, and why is it necessary?

    Well abandonment is the process of sealing an unused or non-compliant well to prevent groundwater contamination. Wells that are not properly abandoned can become pathways for contaminants to enter water supplies. In North Carolina, well abandonment must follow strict regulations to protect the environment. At Cohesion Inc., we ensure that the process is completed safely and in accordance with state guidelines, giving property owners peace of mind.

  • What’s the difference between Phase 1 and Phase 2 Environmental Site Assessments?

    A Phase 1 Environmental Site Assessment identifies potential contamination risks through non-intrusive research, including site inspections and document reviews. If concerns are identified in Phase 1, a Phase 2 Environmental Site Assessment involves physical testing, such as soil and groundwater sampling, to confirm and measure the contamination. Phase 2 helps determine the necessary steps for remediation if contaminants are present.

  • How can underground storage tanks affect property transactions?

    Underground storage tanks (USTs) on a property can be a significant concern during real estate transactions, as they may leak hazardous substances, leading to costly underground tank removal and soil remediation. Buyers, sellers, and lenders often require UST inspections and, if necessary, removal before closing a deal. Ensuring tanks are properly decommissioned can prevent environmental liability and regulatory fines.

  • What happens after an underground tank is removed?

    After underground tank removal, the surrounding soil is tested for contamination. If tests show that contaminants have leaked into the soil, environmental remediation will be necessary to clean up the affected area. This could involve removing contaminated soil, treating it, or stabilizing it with chemicals. At Cohesion Inc., we handle both the removal and remediation process, ensuring that your property is safe and compliant with environmental standards.

  • How do you handle environmental remediation for petroleum contamination?

    When dealing with petroleum contamination, environmental remediation typically involves using methods such as soil vapor extraction, groundwater treatment, or bioremediation, depending on the extent of contamination. Our team assesses the specific needs of each project and develops a tailored remediation plan to safely and effectively remove petroleum pollutants from the environment.

  • What should I expect during a heating oil tank inspection?

    During an oil tank inspection, our experts examine the tank for signs of rust, corrosion, or leaks. We also check the tank’s surroundings, including the soil, to detect any signs of contamination. If issues are found, we provide guidance on repairing, replacing, or removing the tank to prevent environmental hazards. Regular inspections help avoid expensive cleanups caused by unnoticed leaks.

  • How do you determine if a well should be abandoned?

    A well may need to be abandoned if it is no longer in use, has become contaminated, or no longer complies with regulatory standards. We assess the condition of the well and its impact on the environment before recommending well abandonment. Properly sealing a well ensures that it doesn’t become a contamination pathway to groundwater, protecting local water supplies.

  • What are the steps for soil removal during remediation?

    During soil removal for remediation, we first assess the level of contamination. If soil has been impacted by hazardous substances, we excavate the contaminated soil and transport it to a licensed disposal facility. After removal, we conduct tests to confirm that the site is clean and meets regulatory standards. This method is often used for properties with leaking underground tanks or industrial pollution.

  • Why is TPH testing important for properties with petroleum tanks?

    TPH testing is essential for properties with petroleum tanks because it detects the presence of hydrocarbons in the soil and water, which can be harmful to the environment. Regular testing ensures that potential leaks or spills are caught early, preventing further contamination and protecting groundwater. TPH testing is a key part of maintaining compliance with environmental regulations.

  • What are the legal requirements for underground tank removal in Raleigh, NC?

    In Raleigh and the surrounding areas, underground tank removal must comply with both state and federal regulations. These rules ensure that tanks are removed safely, and any resulting contamination is appropriately handled. At Cohesion Inc., we navigate these regulations for our clients, providing professional and compliant tank removal services for both residential and commercial properties.
