Title: Drinking Source Water Protection DHSDWP


1
Drinking (Source) Water ProtectionDHS/DWP
  • Implementation
  • Strategies

2
Prioritization
  • Tier 1 Community water systems
  • Water systems/communities with expressed interest
    in developing drinking water protection
    strategies
  • Coordinate with DEQ activities

3
Oregon drinking water source areas for surface
water intakes
4
Oregon Drinking Water Protection Areas from
Groundwater Sources
5
Reasons to Protect the Source
  • Population increase
  • Increased water needs
  • Limitations to the resource
  • Increased threats to watershed health
  • Water infrastructure is aging
  • Water Quality standards are tightening
  • Emerging pollutants of concern
  • Limited funds for treatment upgrades
  • Security Issues

6
Implementation
  • Land Use Planning
  • County Workshops
  • Newsletter
  • Direct Technical Assistance
  • Funding
  • New/Modified Systems
  • Emergency Response, Waivers, Groundwater Rule
    Groundwater under the Direct Influence of SW

7
Land Use Planning
  • Linking drinking water protection and land use
    decisions
  • Making informed decisions
  • Economic and public health opportunities
  • Role of Source Water Assessments in LUP
  • Where is the water coming from and what are the
    risks
  • How is the linkage established
  • Who has authority? Private vs. Public

8
Multi-jurisdictional
  • Private, municipal and county
  • All combinations exist
  • Privately owned
  • Education BMP resource http//www.deq.state.or.us

  • Sustainable supply for the future Resource
    Adequacy

    Sustainability
  • Avoiding costly treatment, MO
  • New regulations, emerging contaminants of concern

19

    planners, small and large water systems
  • Topics Planning Process, Measure 37, Source
    Water Assessments, Management Strategies,
    Implementation

  • Next? Marion (11/07), Linn (3/08) Hood River
    (6/08), Washington (9/08)

DWP Bulletin
  • Information on state/EPA programs
  • Provide Oregon examples of implementation
  • Discussion of BMPs
  • Resources to communities/PWSs
  • Biannual publication
  • See DHS Website
  • To local govt officials, planning staff, etc.

21
Best Management Practices TA
  • Attached to SWA Reports (system-specific)

  • Initial/Substantial Implementation
  • Provide on request
  • Examples included in trainings/workshops
  • BMP/Fact Sheet Binder for use in field
  • Many available on DEQ Website http//www.deq.state
    .or.us/wq/dwp/assistance.htm

22
Implementation Decision Aid Matrix
  • Purpose for Development
  • Need a means of engaging Public Water Systems
  • Prioritize threats to individual water systems.
  • Identify low-hanging fruit for sense of
    accomplishment
  • Rank each site based on PCS relative risk and
    aquifer sensitivity at that location (
    susceptibility)

GET DOWN TOWN
23
Potential contaminant source
  • a location where there is any activity having the
    potential to release one or more contaminants
    into water at a concentration of concern
  • Database queries (14), field locating in
    sensitive areas, PWS consultations
  • 96 separate categories of PCSs
  • As of 7/05, over 15,300 PCS locations have been
    identified
  • focus must be on HIGHER risks

24
Important points about the SWA Inventory
  • listed potential sources not all inclusive
  • contaminants of concern SDWA
  • potential sources store/uses/produces levels
    that could contaminate PWS sufficient
    likelihood of release
  • not all listed sources were inventoried
  • microbes within 2-yr. TOT
  • watersheds 100 sq. miles sensitive area focus
  • not all listed sources pose actual high risk
  • worst-case assumptions for POTENTIAL
  • not all inventoried sources need managing
  • screen out lower risks focus only on higher
    ones

25
Oregons SWA Inventory ResultsSurface Water
SystemsTop 5 Highest Potential Risks in
Sensitive Areas
  • Managed Forests
  • Sediments, pesticides, fertilizers
  • Roads Stream Crossings
  • Chemicals, petroleum
  • Crops Irrigated
  • Fertilizers, pesticides, sediments
  • Grazing Animals (5 large /acre)
  • Nitrates, bacteria, sediments
  • Above Ground Tanks
  • Petroleum, chemicals

28
Implementation Decision Aid Matrix
  • Rank based on susceptibility and location
  • Related to relative benefit to community, i.e.,
    time-of-travel zone X susceptibility (relative
    risk/aquifer sensitivity)
  • Identify specific BMPs
  • Evaluated with respect to ease of accomplishing,
    e.g., time, cost, staff, and community interest
  • With input from the PWS/Community, transform
    susceptibility matrix into an implementation
    matrix

Funding for Protection
  • DWSRF loans and grants
  • Separate criteria from more traditional
    infrastructure loans Based on risk reduction
  • Grants 20k/PWS/year cumulative if more than
    one PWS in project
  • Project examples pollution prevention TA, BMP
    implementation, signs/fences, secondary
    containment, old well abandonment, ordinance
    development, water conservation, purchase of land
    easement, outreach
  • Current Applications 3 SW (60K) and 8 GW (95K)

33
New and/or Modified Systems
  • New (since June, 1999)
  • Modified (changed so DWSA changes)
  • New wells
  • Inactive wells
  • Pumping operations
  • Tied to sanitary surveys
  • SS form modified

34
What we need from county staff
  • GPS locations of new and emergency wells
  • Datum (WGS 84, NAD 27)?
  • Accuracy
  • Ask if implementing protection strategies or
    interested in TA from regional SWAP contact.
  • Give them our contact info
  • PWS changes on Source Info Pg
  • Water usage
  • New/modified well (including irrigation?)

Source Water Assessment Crossover to Other DWP
Projects
  • Assessments data can be applied elsewhere
  • Emergency Spill Response Notification (OERS) for
    Surface Water Systems.
  • the DWP needs to quickly identify and contact
    those water systems that might be impacted.
  • Data tools should be dispersed throughout the
    regional offices and regularly updated.
  • Solution Use available GIS data gathered during
    source water assessments to create county-wide
    electronic and paper maps that contain intake
    locations and contact information.

37
County Maps
38
Emergency Spill Response Notification
  • Projected Timeline
  • Electronic and paper maps by end of 2007.
  • GIS query capability
  • Annual update of electronic and paper maps.
  • Obtain RiverSpill GIS tool in Portland office
  • Incorporates real time stream flow data that will
    allow DWP to predict the arrival time and
    concentration of chemical and/or biological
    constituents at a water supply intake

39
Source Water Assessment Crossover to Other DWP
Projects
  • Monitoring waivers
  • Use Source Water Assessment data to match
    monitoring requirements to relative risk, e.g.,
    lower risks translates to less frequent
    monitoring
  • Use GIS coverage and data bases
  • Groundwater Rule
  • State option to identify systems that have high
    hydrogeologic sensitivity
  • GIS queries to identify likely systems
