BRAND NAME PURCHASE DESCRIPTION

Background: The U.S. Geological Survey (USGS), National Water Quality Laboratory (NWQL), located in Lakewood, CO, has a requirement for filters for use in Water Mission Area (WMA) water sampling and testing programs. The USGS, WMA, and NWQL strive to maintain national consistency in all 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 filters 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.

Scope: This purchase description covers the requirement for filters required by the NWQL to conduct their analysis.

Requirement: Pursuant to Clause 52.211-6 Brand Name or Equal, this purchase description reflects the characteristics and level of quality that will satisfy the Government’s needs. The salient characteristics that “equal” products shall meet are specified herein.

The following information concerning the brand name providers for each item is provided for the convenience of offerors. PALL (WWW.PALL.COM), manufactures the below listed supplies.

Offerors offering other than PALL products shall meet or exceed the following brand name salient characteristics. Offerors shall include product documentation, including certificates of analysis (COAs) for the two most recent lots, which readily verifies that the product meets or exceeds the brand name salient characteristics listed below. See Clause 52.211-6 Brand Name or Equal.

3. Labeling requirements for both products shall be in accordance with the following:

a. All inks and labels shall be waterproof and on the outside of the housing.

b. Pad print or affix a label to the casing of the filter so as not to interfere with the flow path of the water.

c. At a minimum, the pad print or label shall contain the following information:

· Manufacturer or supplier’s name

· Filter pore size (e.g. 0.45 um)

· Part # XXXX

· Lot # XXXX

d. Capsule filters only: Pad print or affix a directional arrow indicating flow path on the outside of the capsule. The directional label shall be waterproof and shall not peel off or be destroyed during or after contact with water.

4. Lot requirements for both products:

All filters shall be from one capsule and media/membrane lot per shipment. Include a certificate of compliance/analysis with each shipment. Certificate of compliance/analysis shall list the lot number and filter media/membrane of the filters.

Quality Assurance: The acceptability of items delivered hereunder will be determined by quality assurance (QA) testing of each lot at the NWQL. The capsule and disk filters shall be of sufficient quality to support the detection limits attainable by the NWQL for all applicable methods. In addition to the placed order, the offeror shall supply fifty (50) capsule filters and twenty (20) disk filters of each lot to accommodate this QA testing. These capsule filters and disk filters shall be provided at no cost to the Government. Acceptance of the entire lot will be based on the results of these analyses.

The Government will take up to 120 days after delivery to inspect and accept goods.
