Amendment 0002 is being issued to provide responses to questions received.

1. As our laboratory is located outside of the

La Crosse area, we would propose utilizing a commercial shipping service (e.g., FedEx or

UPS) to transport samples to our lab. In order to accurately price these costs, we would need to understand how many sample pickups are anticipated to occur over the period of performance.

Answer: Samples are collected every Wednesday and must be shipped to the laboratory within the allowed holding time for each sample.

2. Additionally, we would like to confirm whether UMESC staff would be responsible for either scheduling pickups directly with

FedEx/UPS or dropping off the samples at an appropriate carrier location for shipment to our laboratory. Please let us know if this approach would be acceptable under the terms of the solicitation."

Answer: It is expected that the Contractor would be responsible for coordinating shipping such that sample coolers would be picked up / dropped off from the UMESC lobby on the day of sample collection. Contractor would be responsible for all delivery of sample coolers and pickup of samples from the UMESC facility.

3. Under the Statement of Work, the tables listing the required tests, you have listed SOC and Inorganics. The way the procurement is set up, a price for these two tests will have to be included in each option year line item. Even though those tests only have to be submitted every 3 years or so.

Inorganics and SOC testing in the base and options due to the uncertainty of when they might be exercised.

4. Also, your Permit requires PFAS testing this
