Environmental Compliance Program Support to AT&T Wireless Network

2026-04-02T15:51:22-06:00October 29th, 2009|Tags: , , |

AT&T operates one of the largest wireless communications networks in the United States. With explosive growth in the highly competitive personal telecommunications market, as well as new technology demands, AT&T's ongoing challenge has been to identify and construct new telecommunications facilities on a very ambitious schedule, all the while minimizing environmental risk and ensuring compliance with the Federal Communications Commission's environmental obligation under the National Environmental Policy Act (NEPA). AT&T's business model typically involves building out a particular geographic market within about a one year timeframe, including conducting all required compliance, engineering, and development-related services.

RCRA Corrective Action Program Human Health and Ecological Risk Assessment at NASA Kennedy Space Center

Abutting the Atlantic Ocean and Central Florida's Banana and Indian Rivers, the John F. Kennedy Space Center is home to a diverse mix of federally and state-listed species and nearly 140,000 acres of diverse wetland and upland habitats, including mangroves, mudflats, salt, cattail, and freshwater marshes, pine flatwoods, oak hammocks, and cabbage palm savannas.

Comprehensive Remediation Strategy to Address Soil and Groundwater Contamination at an NPL Site

2026-04-02T15:50:26-06:00October 24th, 2009|Tags: , , , , , |

The 388-acre Hanlin-Allied-Olin NPL site is a former chemical manufacturing complex near Moundsville, West Virginia. The southern portion of the facility produced chloromethane products and used the chlor-alkali (mercury cell) process to manufacture chlorine and sodium hydroxide. The northern portion of the facility produced numerous semi-volatile intermediates for the manufacture of plastics and other synthetic materials. The long-term objective for the site entailed cost avoidance through the proactive development of two significant remedial components: (i) a major removal action using on-site disposal, and (ii) control of chlorinated solvents in an aquifer used downgradient of the site for a municipal water supply. Both objectives related to a third objective of minimizing the Remedial Investigation/Feasibility Study (RI/FS) scope, thereby reducing long-term cost uncertainty.

Ecological Risk Assessment and RCRA Facility Investigation at a Solid Waste Management Facility – NASA Kennedy Space Center

Geosyntec is providing environmental consulting services to the National Aeronautics and Space Administration (NASA), Kennedy Space Center (KSC) under an Indefinite Delivery Order/Indefinite Quantity (ID/IQ) contract. The services provided are in support of KSC's RCRA Corrective Action Program. The Orsino Storage Yard is a 3-acre facility located in the KSC industrial area. The site was used historically for the storage and staging of electrical equipment, such as transformers, cables, control panels, telephone poles, etc. , and was designated as Solid Waste Management Unit #4 at KSC. Contaminants of concern at the site included pesticides, polychlorinated biphenyls (PCBs), and metals in canal sediment, PCBs in soils, and volatile organic compounds (VOCs) in groundwater.
