Galveston Bay and Houston Ship Channel: Assessing Contamination from Dioxinn
The goal of this project is to evaluate options for reducing contaminant concentrations in fish tissue to levels that are an acceptable risk to consumers. The Texas Department of State Health Services (TDSHS) advises that consumers restrict their consumption of catfish and blue crab caught in the Houston Ship Channel because dioxin concentrations found in them pose a risk to consumers. Dioxin is a generic term for a suite of toxic and environmentally persistent compounds. Overexposure to dioxin can cause a variety of harmful health problems, including cancer, birth defects, diabetes, developmental delays, and immune system abnormalities.
ASCE Creates Living Classroom at Headquarters Parking Lot
The American Society of Civil Engineers (ASCE) earlier this month unveiled a newly renovated parking lot, featuring an array of green infrastructure measures and educational signage, at its headquarters in Reston, Virginia. ASCE Executive Director Tom Smith in a statement described the renovation as transforming a potential source of Chesapeake Bay water pollution into a living classroom. “Thanks to the vision and efforts of staff and volunteers, this project will contribute to the health of the Chesapeake Bay and enhance the aesthetic and functional appeal of our property,” Smith said.
Restoring Clean Water Act should be priority for new administration
Hundreds of billions of dollars have been expended over the past 40 years to attain about 60% of the 1972 goals of the Clean Water Act. If we are to avoid a complete loss of that investment, the newly minted Biden-Harris administration must make the revitalization of the Clean Water Act a high priority during its first year in office. Lack of a strong Clean Water Act to ensure compliance with standards and to measure pollution effects on water quality amounts to a cynical giveaway of federal funds to polluting industries.

FEATURED VIDEO CASE STUDY
View This Month’s Video – From an Always Flooding Parking Lot to a Showcase LID Solution
In this video, we show the specific issues a particular parking lot in Houston, Texas was experiencing that consistently caused it to flood. Then, using time-lapse, we show the LID-based solution being put into place, from start to finish, as well as regular video of the completed solution at work during a rain event.

Ecoraster is the perfect commercial permeable paving system for ground reinforcement, access roads, permeable parking lots, pathways, and permeable hardscape applications. Our plastic paver grid system is an eco-friendly alternative to asphalt and concrete paving.
These 100% recycled pavers are a great option for businesses and commercial contractors looking to reduce their environmental footprint, without sacrificing quality. As a porous paving system, Ecoraster is not only quick and easy to install, it’s an effective stormwater management solution.
Its durability and permeability dramatically reduce long-term costs, especially when compared to traditional pavers. Engineered in Germany, made in Canada and backed by a 20-year guarantee, Ecoraster can be used in commercial paving projects large and small.
Good-to-Know Stormwater Lingo
- Dead storage: The volume available in a depression in the ground below any conveyance system, or surface drainage pathway, or outlet invert elevation that could allow the discharge of surface and storm water runoff.
- Eutrophic: A condition of a water body in which excess nutrients, particularly phosphorous, stimulates the growth of aquatic plant life usually resulting in the depletion of dissolved oxygen. When this happens, less dissolved oxygen is available to other aquatic life.
- Total Maximum Daily Load (TMDL): A calculation of the maximum amount of pollutant that a waterbody can receive and still meet water quality standards. Water quality standards identify the uses for each waterbody, for example, drinking water supply, contact recreation (swimming), and aquatic life support (fishing), and the scientific criteria to support that use. The Clean Water Act (CWA), section 303, establishes the water quality standards and TMDL programs.
