Re: Laboratory Services RFP Questions and Answers, Contract #9061

The City of Madison received the following questions regarding the Laboratories Services request for proposals:

1. Are paper copies of the proposal required, or is email sufficient?

It is OK to only email your proposal—it is not necessary to submit paper copies.

2. Are there any specific groundwater or soil reporting limits required?

Yes, groundwater methods should have reporting limits—and preferably, limits of quantitation—that meet WDNR NR140 standards. Likewise, soil methods should satisfy the WDNR’s NR720 residual contaminant level (RCL) standards. If you provide multiple methods and reporting limits for a parameter, we’ll be sure to only include one in the Form D price comparison.

3. You forgot to attach the Dane County Landfill Protocol 3 description for characterizing sediments.

See the attached protocol.

4. For the leachate metals, you have 17 listed, but you’ll only be running a select group on certain samples. Is there a way to bid these per metal?

The 230 groundwater samples will be analyzed for all analytes listed, with one exception: not all sites require boron. For simplicity in bidding, please assume all groundwater samples will be analyzed for the complete list. If your firm is awarded this contract, however, the City will pay a prorated cost if fewer or additional parameters are required for a particular site.

For metals and hardness in leachate, please bid assuming all 20 samples will be analyzed for the complete analyte list. In reality, each landfill has a slightly different list of analytes required, and the City will pay for each sample on a prorated basis. That is, if your firm bids $90 for 18 analytes per sample, the City would assume a per analyte cost of $5. If only 16 analytes are required for a particular sample, the City would expect to be billed $80 instead of $90.

5. If our lab can’t do the work in‐house, is it OK to not bid on an item OR use a substitute laboratory?

Yes. The City would prefer to work with one firm for all services, and the use of subs is allowed. However, partial bids will be considered. Please follow the RFP instructions for providing information on subs.

6. For the leachate analysis, do you require phenols by EPA 8270 or “total phenolics” by EPA 420.4?

For analysis of leachate samples, method EPA 420.4 is sufficient. For phenols in the Protocol 3 sediment bid item, please use EPA 8270.

7. What is the estimated annual contract total?

Approximately $40,000 to $60,000, but this is not guaranteed.

8. Do you need to provide a local courier for sample pickup?

No. The lab must provide a shipping option: courier, pre‐paid shipping labels, or having a local lab to accept samples will all be considered.

9. Are there any DBE/WME requirements for bidders to the contract?

No—all firms are recommended to apply. Qualifying firms may be required to submit an Affirmative Action (AA) plan as outlined in the sample contract.

Sincerely, Robert F. Phillips, P.E.

1 If chlorine is ≥ 1%, the total concentration of the following 12 compounds must be analyzed; tetrachloroethene;

carbon tetrachloride; 1,1,2‐trichloro‐1,2,2‐trifluoroethane; trichloroethene; chloroform; trichlorofluoromethane;

methylene; chloride; o‐dichlorobenzene; 1,1‐dichloroethene; 1,1,1‐trichloroethane dichlorodifluoromethane; 1,2‐ dichloroethene. The acceptance criteria for these chlorinated compounds is met if the sum of the weight concentrations of these compounds is less than 1% of the total weight. (NR 661.31, Table II).

2 Parts per million (ppm) = mg/l = mg/kg 3 For all parameters identified as requiring TCLP extraction, it is permissible to run a totals analysis first and if the parameter totals analysis is < 20 times the TCLP acceptance criteria, the TCLP analysis is not required.

4 If o‐, m‐ and p‐cresol concentrations cannot be differentiated, the total cresol concentration is used. The acceptance criteria for total cresol is TCLP < 200.0 mg/l.
