Visalia, CA 93291
RE: RFP No. 24-25-32 Annual Contract for Analytical Lab Services
To Whom it May Concern,
Thank you for the opportunity to submit our proposal to the City of Visalia to provide Annual Analytical Laboratory Services. Our firm looks forward to the opportunity to continue to provide these services to the City.
In 1898, Dr. Frederik E. Twining founded our firm in Fresno, California. Initially the organization provided analytical chemistry services from a two-story laboratory in downtown Fresno. In the early 1940’s, the firm began providing Construction Inspection and Materials Testing services. In the early 1950’s, our organization employed civil engineers to provide Geotechnical (soils) Engineering services.
Our Expertise in Analytical Chemistry and Geotechnical Engineering provided the foundation for providing Environmental Services in the early 1980’s.
In 1993, our firm separated our Drilling and Geotechnical Engineering Divisions and formed a Drilling Services Division. Since our founding, we have continually expanded our technical capabilities and services to meet evolving client needs and regulatory agency requirements while maintaining an emphasis on quality customer service. In response to growth and client requests, we began opening offices and laboratories in other areas: Monterey, Sacramento and Riverside.
The Environmental Division of Moore Twining has collectively over 85 years of experience working in the environmental field. This experience includes, but is not limited to, Phase I Environmental Site Assessments, preparation of work plans, petroleum and chlorinated solvent assessment and remediation, groundwater monitoring, municipal water treatment monitoring, agricultural groundwater monitoring, permit compliance, NPDES permitting, well installation and development, and stormwater monitoring. Moore Twining currently holds contracts with multiple municipalities and counties to provide groundwater monitoring and analysis services. Each of these projects include the assessment of data, and an evaluation of the overall project’s needs.
Moore Twining understands that the assessment of a project’s data set is critical to understanding whether the data collected is representative of actual conditions in groundwater. Evaluating the vertical and horizontal extent of contamination from a source area involves looking at source, regional, upgradient, cross gradient, and down gradient data. In order to properly collect data from these areas, detailed and organized work plans should be created so a qualified entity can perform the study, and the data in turn can be reviewed and reported effectively.
Moore Twining’s Fresno corporate office is located at 2527 Fresno Street in Fresno, California. Moore Twining is certified by the State of California Environmental Laboratory Accreditation Program (ELAP) for the analysis of drinking water, wastewater, soil and hazardous waste under ELAP Certificate Number 1371. The firm is also certified as a Disabled Veterans Business Enterprise (DVBE) by the Department of General Services Office of Small Business & Disabled Veteran Business Enterprise Services under DVBE Certificate Number 16472.
Moore Twining welcomes the opportunity to further discuss our firms’ qualifications and information contained in this submittal and look forward to progressing our relationship with the City of Visalia.
Best Regards,
Moore Twining Associates, Inc.
