Topics

Topics

  • Project Planning – Implementation of the PMPro model

  • Analysis of Filtration Technology – Meeting the needs of a rural Indian community

  • Community Capacity Building – Methods used to equip the community with knowledge of project planning

  • Strengthening Relationships Between IHS/Tribe/EPA


Background history

Background & History

  • Mescalero Apache Tribe, New Mexico

    • 2006: Two water systems that utilize fresh water springs were classified by EPA as Groundwater Under the Influence of Surface Water

    • 2010: Order on Consent Issued – EPA wanted compliance within 18 months

    • IHS & Tribe partnered to develop and implement a plan to identify solutions to meeting the EPA requirements


Background history1

Background & History


Project planning

Project Planning

  • Current IHS Sanitation Facilities Construction Project Management Guideline

    • Project Development

      • Identify Project – Who, What, Where, When, Why?

      • Identify Planning Activities – What needs to be done, what information is needed?

    • Planning & Design

      • Execute Planning Activities – Data collection

      • Report of Findings – Engineering Report (used for design)

    • Construction Documents

    • Construction

    • Close-out


Project development

Project Development

  • Identify Project – New Water Source or Treatment Technology

  • Identify Planning Activities – Alternatives Analysis Report

    • Groundwater

      • Characteristics of Current Groundwater, Formations, etc.

      • Hydrogeologic Study – Preliminary Siting of New Well

    • Filtration

      • Conventional vs. Alternative

      • Current Water Quality

  • Objective of the Alternatives Analysis – Clearly present all options to the Tribe so they can make a well informed choice on meeting compliance

  • Tribe Submitted Project Development to EPA


2 planning design

2. Planning & Design

  • Execute Planning Activities

    • Data Collection

    • Prepare Alternatives Analysis Report

    • Seek input from stakeholders – Tribe & EPA

    • Identify potential risks and how to mitigate

    • Obtain chosen alternative from Tribe

  • Report of Findings – Finalized Alternatives Analysis Report


Regulatory framework

Regulatory Framework

  • Surface Water Treatment Rule (1989):

    • MCLG of zero for girardia, viruses, & Legionella

    • National Primary Drinking Water Regulations for PWSs using groundwater under the direct influence of surface water (GWUDI)

      • 99.9% (3-log) removal of girardia, 99.99% (4-log) removal of viruses

      • Definition of GWUDI – shifts in turbidity, temperature, conductivity, pH that correlate with climate conditions

      • Approved Technology: Conventional/direct filtration, slow sand, diatomaceous earth, and “other” filtration technologies


Regulatory framework1

Regulatory Framework

  • Long Term 2 Enhanced Surface Water Treatment Rule:

    • Cryptosporidium

    • Bin Classification System

  • Filter Backwash Rule – reporting, treatment, and record keeping requirements for the recycling of spent filter backwash

  • Bin 1: 99.9% (3-log) removal of girardia and 99.99% (4-log) removal of viruses combined with disinfection


Analysis of filtration

Analysis of Filtration

Immediate Compliance

  • Direct Filtration: coagulation and filtration, excludes sedimentation

  • Conventional Filtration: coagulation, flocculation, sedimentation

  • Diatomaceous Earth Filtration: precoat filter media on a support filter media

  • Slow Sand Filtration: <0.4 m/hr

  • Alternative Filtration: membrane (micro, ultra, nano, ro), bag, cartridge, bank

Contingent Compliance


Alternative filtration

Alternative Filtration

  • Immediately disregarded – not immediate compliance, pilot testing required

  • Section 141.73 (b) of NPDWR – Approval of alternative filtration with the following:

    • Combined with disinfection

    • Demonstration to the State using pilot & integrity testing

    • 99.9% removal and/or inactivation of Giardia

    • 99.99% removal and/or inactivation of viruses

    • 99% removal of Cryptosporidium

    • The State approves the use of the filtration technology


Alternative filtration1

Alternative Filtration

  • EPA agreed compliance with the following exceptions:

    • Role of the “state” would be Region 6

    • Challenge test documents forwarded to them

    • Pre-filters installed

Results

Results

  • Groundwater option chosen

  • Final Report Published - EPA funded the project to drill wells

  • IHS funding infrastructure & capital improvements

  • Application to another GWUDI system

    • Tribe working more independently to scope planning projects

      • Results in other funding sources

    • EPA working more closely/directly with Tribe

    • Limited role of IHS

    • Application to ISWMP
