3 - Contaminant Source Inventory (CSI)
of the CSI is to identify known and potential sources of groundwater
contamination within the WHPAs. Once identified, the contamination
sources can be managed in order to reduce the risk they pose to
the drinking water supply.
water supply systems that supply water to both private and public
users, the MSU water supply system provides water to mostly users
at MSU. Since access was available to almost all properties within
the WHPAs, more comprehensive facility inspections than those normally
associated with a CSI were possible. As such, common approaches
used by most communities for conducting a CSI were modified to fit
the conditions at MSU.
The MSU CSI
consisted of six primary tasks:
- A federal
and state database search.
environmental inspections of properties within the State-approved
WHPAs. The inspections took 13 months to complete, with 54
properties being inspected. The inspections involved a field walk-through
investigation of the properties sometimes accompanied by, and
always followed up with, interviews of property managers. Data
obtained during the inspection were recorded on a form developed
by the WHPP Team.
- Preparation of a comprehensive listing of all known underground
and aboveground storage tanks (USTs/ASTs) on campus. Considerable
effort has been made by MSU to identify problematic storage tank
systems and remediate any associated environmental concerns. Most
of MSU's UST systems have been permanently removed or have been
replaced with aboveground storage systems. During the CSI, information
regarding MSU storage tanks was collected in order to confirm
that no significant environmental risk is associated with these
Well Records Review - Identification of Abandoned Wells - Collection
of available information on the water wells as part of a campus-wide
abandoned well program. MSU has a variety of well types on
campus. Examples of such wells include water supply wells, monitoring wells, lysimeters, and irrigation wells.
To assess the status of MSU's wells and find abandoned wells, the Team developed a well database from the available MSU water
well records. These records included: State water well records
available from the Ingham County Health Department, MDEQ, documents
available in MSU well files, and IPF Engineering and
Architectural Services Department document archives. Other sources
of well information included an interview with former a MSU employee
familiar with the campus area and onsite inspections of MSU properties.
- A review
of known and potential sources of contamination within portions
of the MSU WHPAs extending off-campus. MSU reviewed the EcoSearch
report for listed sites within MSU WHPAs that extend off-campus.
MSU staff augmented the EcoSearch information through follow-up
reviews. Additionally, MSU staff conducted a limited drive-by
inspection of the off-campus WHPAs and obtained relevant information
about the findings from the MDEQ.
- A limited review of rail transport through the MSU campus.
Two rail lines, CSX and Grand Trunk, are located within the WHPA
Results of the Contaminant Source Inventory
Once this extensive inventory process was completed, the Team addressed known sources of contamination and established management strategies for potential sources of contamination within the WHPAs.
The Contaminant Source Inventory was updated in 2006 and again in 2014 with the assistance of Team members from MSU Environmental Health and Safety and the Land Management Office, as well as farm managers throughout south campus. The CSI updates consisted of database searches, surveys of farm managers and walk-through site visits.
