Who the MSD Impacts
Unless you are the applicant: An MSD does not affect your property
An MSD does not affect your water well
There are no requirements on you
Drinking water supplied by the City is not affected

What an MSD is
Voluntary deed restriction to prevent the use of contaminated groundwater
State program created in 2003, administered by TCEQ (the State agency)
City process created in November 2007, administered by Public Works & Engineering
TCEQ cannot approve an MSD without the City Councils support

What an MSD is
An alternative method to address groundwater contamination
Houston has shallow groundwater contamination scattered across the city
This program only considers very shallow contamination (up to 200 below the surface)

City Water Supply
Houstons drinking water comes from either deep aquifers or surface waterNearest public water supply well
D-82 #1, depth 565 ft.
D-82 #2, depth 503 ft.

Problems of Traditional Remediation Methods
Groundwater must be cleaned to drinking water standards even if:There is no need or desire to use it, orWater bearing zone is too silty, too salty, or
low producing
Groundwater remediation to drinking water standards is inefficient, costly, and can take decades

Applicants Responsibility
An MSD does NOT excuse the applicant from reducing other risks to the public
Owner must still address:Non-Ingestion SoilVaporsRunoff and other flows

Citys Requirements of the Applicant:
Site must already be in a State or Federal clean up program
Site must have been thoroughly investigated
Data must show that the groundwater plume is stable or diminishing.
A Professional Engineer (P.E.) or Professional Geologist (P.G.) must be willing to certify that the plume is stable or contracting.

Why Support An MSD?
Protects the public from consumption of shallow contaminated groundwater
Encourages clean-up of contaminated sites through participation in a State or Federal program
Promotes redevelopment of under-utilized properties

MSD Sites in Houston

Steps in the Process
Based on input from this meeting and the public hearing, the City will consider supporting an MSD
If supported, the applicant submits its application to the TCEQ
TCEQ grants or denies the MSD
If granted, the City files a deed restriction on the property
