Reverse Osmosis Desalination
Construct a small-scale desalination plant on campus to meet the university's water needs.

Proposed Site
Proposed
Site
Are there potential sites for brine disposal or hazardous waste sites within 100 miles?
Brine Disposal
Hazardous waste disposal sites
Wastewater treatment plants

Water Sampling

Park
- Enterococcus bacteria is 104 colony forming units (CFU) per 100 ml.
University
Beach
University Beach
JFK-A
- When the counts of Enterococcus bacteria are above the 104 (CFU) level, swimming is not recommended.
Testing Site for the EA
- University Beach, considering it is the closest for testing the future impacts of the desalination plant.
Testing Site for EA
The proposed area is in a high-risk flooding zone of Ward Island, with a history of flooding every 100 years.
Sea level rise
Flooding Issues
Regional land subsidence
In the future, areas can be inundated at higher frequencies.

Vegetation Types
Vegetation
&
Soil Types
- Highland: Spartina spartinae, Borrichia frutescens, Distichlis spicata, & Sueda linearis
- Shannon-Weiner Index: H=1.246501879
- Lowland: Paspalum vaginatum
- Shannon-Weiner Index: H= 0
Soil Types
Victoria series which consists of dark, calcareous or chalky, crumbly soils that are called blackland.
Soil
Types
Structure
- Grainy consistency
- Can hold water in times of rainfall for a short time
- Blackland soils are dry they tend to crack
- If wet it slowly takes in water and expands
Erosion
Erosion
The blackland soils are susceptible to moderately severe erosion, but if it is carefully managed with the surrounding soils, it is possible to construct on the proposed site.
Are sources of saltwater for desalination available? If so, what are they and the salinity concentration?
Sources of saltwater for desalination
- Sources of available saltwater
- Oso Bay: 32% salinity
- Corpus Christi Bay: 33% salinity
Environmental Impacts
- Near the water there is already litter polluting the water
- Endangered bird species live near the site or in the vicinity
- Brown Pelican
- Reddish Egret
- White-faced Ibis
- Wood Stork
Environmental
Impacts
Social Impacts
- Proximity to Church and student living
- Disruptive
- Traffic, smell, noise
- Extra costs due to building the plant in this location
- Arises questions:
- How would the church be affected by the plant?
- How the community would feel about tearing down a church
- How would students living on campus respond to the plant?
- Would the plant need overnight security?
Impacts, Inputs, & Needs
Public Inputs
- Who else may have a problem with the plant?
- Nearby residents
- Naval base workers
Public Input
Transportation Needs
- Increases traffic
- Expand roads?
Transportation
Needs
Economic Impacts
Economic Impacts
- Increase in jobs
- Proximity to campus
- Reduction of other costs
- Demolition of church
- Expanding of roads
- Extra security
- Construction
- Environmental factors
Final Verdict
- Yes, a desalination plant should be implemented, but the location should be changed.
