A. Introduction:

The U.S. Geological Survey (USGS), National Water Quality Laboratory (NWQL) has a requirement for pH buffer solution, conductivity standards, and deionized water for use in Water Resource Discipline (WRD) water sampling and testing programs.

B. Background:

The U.S. Geological Survey (USGS), Water Resource Discipline (WRD), and National Water Quality Laboratory (NWQL) strive to maintain national consistency in all of the environmental samples collected by their personnel. The scientific analytical data from these samples is available and presented for use by other agencies and the public. It is extremely important that the supplies acquired hereunder will continue to provide consistency with the data that has been obtained, in some cases, for over a decade. Consistency in data is critical for the NWQL and USGS programs across the country for which the Lab does analysis.

Unlike commercial labs, the NWQL, and the USGS programs they support, monitor trends in the data. In addition, the pH buffer solution, conductivity standards, and deionized water are also provided to field personnel through the National Field Supply Service (NFSS) for use in the collection of environmental samples.

C. General Requirements:

The Contractor shall be required to provide pH buffer solution, conductivity standards, and deionized water listed below to the NWQL and the WRD pursuant to this contract as ordered from time-to-time during the term of this contract.

D. Brand Name Manufacturer:

Ricca Chemical Company https://www.riccachemical.com

E. Brand Name or Equal Salient Characteristics: The following brand name or equal salient characteristics specify the minimum requirements that items shall meet to be acceptable and that will satisfy the Government’s needs.

1. Required supplies

a. pH Buffer Solutions

The Contractor shall supply pH buffer solutions in the following pH values, volumes, and packaging with a remaining shelf life of no less than twelve (12) months upon arrival at the USGS National Water Quality Laboratory (NWQL).

Salient Characteristics for all pH buffers:

• pH verifications shall be performed for the certificates of analysis at an ISO 17025 accredited laboratory.

• All material used in the preparation and verification of the conductivity standards shall be certified traceable to National Institute of Standards and Technology (NIST) standard reference material (SRM) via an unbroken chain of comparisons.

• As appropriate for the process, test products shall be prepared and tested with support equipment (e.g.

volumetric glassware, balances, and thermometers) that is compliant with ISO 17025 accreditation.

• All products shall be prepared according to master documents and validated methods that assure consistent manufacturing for minimal lot to lot variability.

https://www.riccachemical.com/

• pH shall be measured at 25°C and a minimum of eight (8) other temperatures encompassing the entire range from 0-50°C. At 25°C, the pH measurement shall be certified to ±0.01 pH units and test accurate to ±0.02 pH units at USGS NWQL. At all other temperatures, the pH measurement shall be accurate to ±0.05 pH units.

This will ensure product quality and Contractor adherence to a quality plan. The quality of the products shall be traceable to National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) and other NIST standards when suitable standards exist.

The acceptability of items delivered hereunder will be determined by quality assurance (QA) testing of each lot at the NWQL. The pH buffers and conductance standards shall be of sufficient quality to support the control limits provided by the NWQL for all applicable concentrations. In addition to the placed order, the offeror shall supply one (1) bottle from each pH lot and one (1) bottle of conductance standard from each lot to accommodate this QA testing. These solutions and standards shall be provided at no cost to the Government. Acceptance of the entire lot will be based on the results of these analyses.

The USGS NWQL reserves the right to return, at Contractor’s expense, unacceptable products tested at the USGS NWQL that do not meet the contractually obligated quality standards stated within at no cost to the Government for replacement or refund.
