The megasite in Bryan County is known by many names but it is undoubtably the largest single construction project in the Ogeechee watershed. The site will be home to an automobile manufacturing facility owned and operated by Hyundai. Additionally, countless support businesses, warehouses, and housing developments are being built — all connected by water and sewer infrastructure and expanded trucking corridors. These pressures, and others, strain the Ogeechee Basin’s already delicate ecosystem.

Ogeechee Riverkeeper is doing all it can to conserve undisturbed natural resources, improve already-impacted waterways, and hold parties responsible for the parts they play in the negative changes.


Permits and Comments

As part of Ogeechee Riverkeeper’s mission to protect, preserve, and improve the water quality in our basin, ORK will make official comments in response to proposals and permit applications. These comments are related to the impacts of the Megasite. View all comments.

Georgia Comprehensive State Water Management Plan – 2008


Ogeechee Riverkeeper is conducting long-term monitoring, upstream and downstream, of the Megasite. This monitoring includes baseline data and will ORK to know if any number of indicators fluctuates. Remote probes check dissolved oxygen (DO), pH, conductivity, and temperature every thirty minutes.

Note: Occasional breaks in data occur when probe requires maintenance.

Dissolved Oxygen (DO) refers to the O² dissolved in water. The amount of DO is an important part of stream ecosystems, because it determines whether or what types of organisms can live in a given stream segment. Georgia standards for dissolved oxygen specify a daily average of 5.0 mg/L and an instantaneous minimum of 4.0 mg/L.

The pH of water is a measure of the concentration of hydrogen ions. A pH value of 7 is neutral, below 7 is acidic, and above 7 is alkaline. Georgia standards for pH specify pH in a range of 6 – 8.5 as acceptable.

Specific conductivity estimates the total mass of ions in water. Conductivity is proportional to the relative amount of electricity that can be conducted by water. The more dissolved ions present the higher the conductivity. Conductivity can be correlated to pollution loads. There are no state standards for specific conductance for the Ogeechee River.
