- Groundwater in the northern portion of the planning area can be acidic and have high concentrations of iron.
- Overpumping of the Gulf Coast Aquifer has led to subsidence and saltwater intrusion.
- A saltwater barrier to prevent bay water from impacting the fresh river water on the lower Neches River may be
needed to ensure a safe supply of surface water for Beaumont and Port Arthur.
- Several smaller cities will need to upgrade their water treatment plants to comply with the amendments of the
Safe Drinking Water Act.
- Wastewater from paper manufacturing plants has impacted the quality of the water in Sam Rayburn Reservoir,
while high mercury levels in fish in Sam Rayburn and B. A. Steinhagen reservoirs has led the Texas Department of Health to issue fish-consumption advisories.
