Class V Underground Injection Wells (UIWs) are structures used to inject non-hazardous fluids underground for varying water-management purposes. Fluids are injected either into or above an underground source of drinking water. Examples of Class V UIW include, among others, surface water runoff drainage wells, septic systems, storm water dry wells, motor vehicle waste disposal wells, and industrial, commercial, and utility disposal wells.
When closure is required for a Class V UIW, it must be conducted in a manner that is protective of human health and all waste materials removed from the wells must be disposed of in accordance with all applicable laws and regulations. Owners or operators for all types of Class V UIW must notify the corresponding regulatory agency of the intent to close said Class V UIW. The owners or operators of a Class V UIW that is utilized to dispose of industrial or other wastes must submit a closure plan detailing, at a minimum, the inventory information concerning the well, procedures for removing any sludges or wastes from the well, and procedures for plugging the well.
There are two type of soil remediation options: in-situ (on-site) and ex-situ (off- site). In-situ and ex-situ activities vary in size, scope, duration, project-specifics and the particular needs of the client. In-situ remediation includes three categories: washing, venting, and bioremediation. Typically, there is a lower up-front cost for in-situ remediation; however, cost can increase due to project specific variants, and this will always be discussed with the client prior to commencement. Ex-situ remediation involves the removal of contaminated soil that is then processed off-site. Soil is isolated in a controlled environment, and the process is not affected by weather/ temperature conditions. While there is a higher upfront cost for this, ex-situ remediation is typically more efficient in removing the bulk of contaminants.
At Cider Environmental, we provide both in-situ and ex-situ remediation strategies. We work closely with our subcontractors to provide the highest quality service with the lowest cost.
The remediation of contaminated groundwater can be a particularly daunting and intimidating process for a client. Though, there are significant challenges involved in proper groundwater remediation, the development of new methods and technology have aided in finding viable solutions for successful remediation that satisfies the regulatory agencies requirements.
At Cider Environmental, we have the technical capability and field experience to apply the newest and most cost-effective technologies available. Our approach is tailored to meet the needs of our clients and we value their input. The work plan that is drafted takes into consideration the particular site-specific details, deadlines, and budget concerns the client may have.
An underground storage tank (UST) is a tank or any underground piping that has at least 10 percent of its combined volume underground. The closure of a UST requires significant understanding of varying governmental rules and regulations. The UST must be removed, disposed of and documented appropriately. The knowledge of site history, engineering experience and ability to effectively communicate with regulatory agencies are absolutely critical to a successful UST closure.
At Cider Environmental, we are knowledgeable in governmental requirements and are able to effectively communicate with the regulatory agencies. Our team’s practical and technical skills are invaluable in providing swift and efficient closure. The results are documented in a high-quality report, structured to contain the technical data required in a presentation that is complete, thorough and easy to understand.
