ENVIRONMENTAL Project Experience - Regulatory Compliance

Water Quality Testing

Aquifer Storage and Recovery Well, Seminole County, FL

E Sciences is part of a team of engineers, geologists and scientists participating in the development of an aquifer storage and recovery (ASR) well system to provide cost-effective alternatives to storing and using potable water during times of surplus and demand.  E Sciences assisted in the development of the water quality testing program during project development, consisting of pre-cycle, baseline testing, source water, and a minimum of four separate cycle tests.  Various constituents of concern are analyzed as part of this testing for Primary and Secondary Drinking Water Standards.

Wastewater Compliance Investigation

Theme Park Client, Orange County, FL

E Sciences was called upon to investigate the source of high levels of chlorides in the wastewater stream of a large Central Florida theme attraction comprised of multiple parks.  A regulatory agency had initiated processes to implement daily non-compliance fines until such time as the exceedences were identified and corrective actions taken to restore the wastewater stream back to allowable permitted discharge limits.  E Sciences developed a work plan with the client and regulatory agency and negotiated a suspension of penalties during the evaluation period.  The work plan involved a methodical sampling regime to systematically identify the source(s) of chloride exceedences.  Sampling events were scheduled over several weeks during the late night hours to minimize disruption to primary park guest activities and minimize daily maintenance activities.  The source of the chlorides was discovered and corrective actions developed to lowering levels into compliance and thereby eliminating potential fines from the regulatory agency.  The adopted corrective action involved the installation of a Eurotherm pH control system with telemetric data sensors with in two lift stations for continuous remote chloride monitoring and reporting, adaptation of nightly operations and maintenance, and training of maintenance and professional staff to reduce future chloride discharges.  E Sciences staff supervised the installation of the new system and conducted post-installation monitoring to ensure the effectiveness of the new system.

 Underground Tank System Upgrade

Mass Transit Facility, Broward County, FL

E Sciences provided assistance with developing the environmental portions of construction contract documents for an underground storage tank (UST) system upgrade project for 13 USTs with a combined total volume of 392,000 gallons and a baseline assessment of groundwater contaminant concentrations.  The baseline assessment was designed to provide justification for state funding for petroleum impacts around the USTs and to aid in planning the management of impacted soil and groundwater during the UST replacement.  While working on the baseline assessment, a fuel delivery resulted in an off-site diesel fuel discharge.  E Sciences provided the client with assistance on how to abate the source, reduce their third-party liability and assisted with negotiating an off-site access agreement.  A limited contamination assessment was performed to satisfy regulatory requirements.
