Construction sites near bodies of water can influence rivers and lakes becoming turbid. Turbidity is the amount of cloudiness in the water. There are several ways a body of water can become cloudy. The Clean Water Act regulates the amount of turbidity allowed, and the National Pollutant Discharge Elimination System (NPDES) program requires regular testing by measuring the Total Maximum Daily Load (TMDL) or maximum amount of a pollutant allowed to enter a body of water that meets the Environmental Protection Agency’s (EPA) water standard.
What causes turbidity?
Turbidity can vary from a river full of mud (high turbidity) to a spring that is entirely transparent (low turbidity). There are natural elements that cause fogginess in the water like algae that are not in our control. However, on a construction site, there are several chemicals like paint and concrete that need to be disposed of correctly to avoid too many pollutants in our water. Rainfall, especially in Florida, can increase the probability of such chemicals running into a body of water.
By having controls like dewatering, you avoid the dangers of affecting clean water. However, not disposing of the sediments the right way can also add pollutants into our local water bodies. When you have decided on a dewatering system, take into consideration where the extracted water is being disposed.
How can I test for turbidity?
There are several tools on the market that measure turbidity. Some major rivers have state of the art meters that provide an instant reading. In most cases, you will find yourself having to get the measurements on your own. Each state has their regulation on what is the acceptable TMDL.
Normally, using a meter or a sensor to measure turbidity is the way to go. KCI does offer turbidity measurement services. This will give you peace of mind that the professionals are taking care of your TMDL.
