The laboratory routinely analyzes the effluents of the approximately 175 industrial and 450 municipal permitted wastewater facilities in Harris County. The operators of these facilities are promptly notified of any permit exceedances so that corrective action can be taken. Most of these notifications result in an immediate satisfactory improvement of the facilities operations.
The laboratory also provides analytical services for special investigative samples that may present environmentally hazardous conditions. Primarily submitted by our Field Investigators and Emergency Response personnel, these samples may be the result of a citizen complaint, an illegal discharge, or an emergency situation such as a spill or plant emissions event.
