Underground Storage Tank Removals, Groundwater Monitoring  

Plumas UST RemovalH&A was retained to provide Underground Storage Tank removal, monitoring well installations, and regulatory compliance services. Twenty-one (21) heating oil USTís were removed throughout the school district. As part of the removal process, soil samples were collected and analyzed and found to contain high levels of petroleum hydrocarbons. H&A services included the preparation of workplans, the installation of monitoring wells, evaluation of hydrogeological data, groundwater sampling and analyses, and technical reporting. Through ongoing efforts of evaluation of chemical and hydrogeological data, H&A has been able to achieve regulatory closure of all twenty-one leaking UST sites. These services were provided without disruption of the schools while protecting human health and the environment.
