At PWS Laboratory, we make the regulatory tape look easy. Our mission is to deliver timely, accurate, and reliable analytical data using TCEQ NELAP-approved methods to municipal water and wastewater systems. We ensure systems meet reporting requirements timely to be compliant with the associated TCEQ rules avoiding any regulatory reporting violations. With over 50 years of comprehensive experience across local, state, and federal levels, we provide more than laboratory water and wastewater analyses—we provide excellent customer service to help systems maintain compliance and we also provide field collection services 7 days a week for emergency, special sample needs such as for microbiological analytical requests. Other services include chemical delivery and other analytical needs such as nitrification diagnostics. Being customer service driven, we are committed to being your ONE-TRUSTED, ONE-STOP SHOP. We got you! Please contact us today at (214) 334-1283.

At PWS Laboratory, we deliver reliable and timely analytical testing and reporting, backed by customer-first support—including field collection services 7 days a week.
