Answer: You're right to be concerned. Turbid water that exceeds regulated allowances can be very costly. It can affect your firm's reputation in the field, result in regulatory fines, and cause job-site shut downs.

Rules vary from state to state, but generally speaking, anytime a construction site has a significant portion of disturbed ground exposed, a remediation plan is required to ensure that the exposed soil does not exit the property. Local, State, and even Federal inspectors can pay your site an unexpected visit. They will conduct a turbidity test to ensure compliance. To avoid any resulting and unwanted surprises, you'll want to make sure your SWPPP is in order and working as it should.

Test Turbidity by Measuring the Site Runoff

Ultratech Turbidity MeterTaking a turbidity test with a turbidity meter is the first step for an effective sediment control program. First, identify the locations that stormwater leaves your job site. Take individual samples for each of these locations, conducting a separate test on each using a turbidity meter. Turbidity testing is as best management practice for both on-ground construction projects and in-water construction projects.

In a nutshell, turbidity meters measure the amount of light that is scattered at a specific angle. Light is scattered and absorbed by particles in the water. This scatter can be in any direction. When a particle is much smaller than the beam of light, the scattering is symmetrical in all directions. The turbidity meter converts that test reading into a turbidity measurement. By using a turbidity test to check the cloudiness of the water leaving the site, you can get an accurate measurement of sediment leaving the job site.

Many states require this turbidity test information be loaded into a web-based tracking program as part of compliance measures. The data also helps you justify cost associated with installing soil loss controls and proves that the money spent is money saved related to fines or stopped work.

Should the turbidity reading from the testing exceed the allowable limits, you will want to act quickly to avoid repercussions.
