Corrosive Soil Sampling Program, RFP No. CORR-25-01

I. STATEMENT OF WORK

A. BACKGROUND

The East Bay Municipal Utility District (District or EBMUD) provides water service to much of

Alameda and Contra Costa counties, covering a 332-square-mile area from Crockett in the north

to San Lorenzo and parts of Hayward in the south, and from San Francisco Bay eastward

through Oakland, Berkeley, Walnut Creek, and the San Ramon Valley. The District also operates

in also operates facilities in Amador, Calaveras, San Joaquin, and Sacramento counties. In 2018,

the District adopted ductile iron pipe (DIP) as its standard pipeline material. Because DIP is

susceptible to corrosion, it is essential to understand the corrosivity of soils within the service

area to properly design and implement corrosion protection measures. The purpose of this

contract is for the Proposer to collect and document in-situ soil and groundwater samples and

deliver them to District laboratories, where the District will analyze their corrosivity to support

pipeline cathodic protection design and recommendations. These environmental sampling

services are required throughout the District’s service area.

B. SCOPE

1. It is the intent of these specifications, terms, and conditions to describe in-situ

soil and groundwater sample collection and laboratory delivery for the District to

characterize soil and groundwater corrosivity for pipeline cathodic protection

recommendations. These environmental sampling services are required

throughout the East Bay Municipal Utility District’s (District) service area and

parts of Amador, Calaveras, San Joaquin, and Sacramento counties.

2. The District intends to award a three-year contract (with two options to renew

for one-year terms) to the Proposer(s) who best meets the District’s

requirements. Under this proposal, the District reserves the right to award

multiple purchase orders for this service and add Proposers as needed or

required.

3. The District estimates the soil collection and corrosivity analysis of approximately

200 soil samples per year, with about 2-15 samples collected per project location.

It is estimated that groundwater will be encountered at 25 percent of the sample

locations. Actual quantity and frequency of requested service from any one

Proposer may vary.

4. Proposers meeting the qualifications outlined in Section C will be placed on an

Approved Vendor List. The District may invite vendors from the Approved Vendor

List to submit proposals for individual projects as needed.

5. The District will award jobs on a case-by-case basis, evaluating proposed costs

and vendor availability. Project specific proposals shall be submitted within five

RFP NO. CORR-25-01

business days and shall include estimated costs (in accordance with RFP bid rates)

and an estimated schedule (based on the Proposer’s available resources and

current commitments). Should the proposed schedule fail to meet the District’s

requirements, the District reserves the right to solicit a proposal from another

Proposer. Upon acceptance of a satisfactory schedule, the District will issue a

written authorization to proceed.

C. PROPOSER QUALIFICATIONS

which they are being retained (e.g., traffic control, soil and groundwater

sample collection) for a minimum of ten years.

D. SPECIFIC REQUIREMENTS

1. Upon District identifying project location for soil sample collection, Proposer will

be notified of project location(s), number of sample(s), sample location(s) and

depth(s). Proposer will be provided with project-specific chain of custody forms.

See Exhibit F for example chain of custody forms.

2. Proposer shall secure all necessary permits. If the permitting agency is imposing

additional conditions or fees which are greater than standard, the Proposer must

notify District representative prior to agreeing to the additional conditions and

the payment of fees.

b. Precautions shall be taken to prevent contamination of soil sample during

sample retrieval.

c. Use of mechanical equipment is prohibited for the first 8 feet of soil

sampling. Exceptions to this requirement may only be made with prior

written authorization from the District.

d. Proposer may utilize mechanical equipment to penetrate paved surfaces

as necessary to access underlying soil.

4. Proposer shall collect soil sample(s) for analysis, as follows:

a. Collect two 1-gallon bag soil samples at each location. Place samples in

sealed District-provided plastic bags.

b. Soil sample shall be a composite sample taken from 3-feet to 8-feet below

grade. In some cases, deeper samples (up to 10-feet) may be required. If a

deeper sample is required, additional pricing will apply (as specified on

Proposal Form).

c. If groundwater is encountered at sample depths, collect two 125-ml plastic

bottles of groundwater for chloride testing. Plastic bottles shall be District-

provided.

d. All samples must be labeled with the sample ID, project title, sampling

date and time, sampling depth, and the sampler’s name.

e. Complete the chain of custody form(s).

f. Maintain, handle, and store samples in a manner meeting requirements of
