Lab Sampling & Reporting Serivces

The City of La Marque is requesting sealed bids for TCEQ-required laboratory sampling and reporting services for its wastewater treatment plant (3.0 million gallons per day) and public water system, with bids due July 29, 2026 at 10:00 a.m.

The contractor must hold current TCEQ and NELAC accreditation and laboratory certifications. Services include weekly and monthly wastewater sampling, monthly bacteriological sampling of the water system (20 samples), quarterly biomonitoring testing, annual TCLP sampling, monthly Discharge Monitoring Report preparation, and compliance assistance. The contractor must provide sample containers, preservatives, chain-of-custody documentation, and electronic reports meeting TCEQ deadlines.

The initial contract term runs twelve months beginning October 1, 2026, with options to renew on a monthly basis for up to four additional consecutive one-year terms by mutual consent, provided negotiations occur at least thirty days before expiration. Either party may terminate with thirty days written notice.

Bidders must submit a detailed fee schedule with unit prices for all line items, including CBOD, total suspended solids, ammonia nitrogen, total copper, dissolved oxygen, pH, enterococci, bacteriological sampling, biomonitoring, TCLP sampling, and reporting. A price revision clause permits bidders to request firm-pricing exceptions for specific items, with any increases subject to documentation of actual source-of-supply cost increases and thirty days written notice to the City.

Sealed bids in three copies plus a flash drive are submitted to the City Clerk's Office at 1111 Bayou Road, La Marque, Texas 77568; faxed or emailed bids are not accepted. Bid opening occurs at 11:30 a.m. the same day. Questions should be directed to Shannon Breaux, Director of Public Works, at (409) 572-9901.
