Overview

  • Enacted in 1974 to:

    • Protect public health by regulating the nation’s public drinking water supply

  • Amended in 1986 and 1996

    • 1986: Establish NPDWS for 83 specified contaminants

    • 1996: Emphasis on public involvement and public right to know (i.e., annual reports). Identified need for funding.


Drinking water comes from a ‘watershed’ which is the land area over which water flows into the river, lake, or reservoir; not just the part of the river or lake that you can see

Who is regulated
Who is regulated? land area over which water flows into the river, lake, or reservoir; not just the part of the river or lake that you can see

  • Public water systems

    • “System for the provision of water to the public for human consumption through pipes or other constructed conveyances, if such such system has at least 15 service connections or regularly serves at least 25 individuals”1

  • Chain of command

    EPA State Local water supplier

    1 SDWA § 1401(4)(A)


Guiding regulations
Guiding Regulations land area over which water flows into the river, lake, or reservoir; not just the part of the river or lake that you can see

  • National Primary Drinking Water Regulations (NPDWR)

    • Set enforceable maximum contaminant levels for particular contaminants in drinking water or required ways to treat water to remove contaminants

  • National Secondary Drinking Water Regulations (NSDWR)

    • Relate to the aesthetics of water, not health effects (i.e., color, taste, odor)


National primary drinking water regulations
National Primary Drinking Water Regulations land area over which water flows into the river, lake, or reservoir; not just the part of the river or lake that you can see

  • Standards set through a 3-step process:

    • EPA ID’s contaminants that may affect public health.

    • EPA sets a health goal (MCLG)

    • EPA determines a maximum contaminant level (MCL) or a required treatment technique


National secondary drinking water regulations
National Secondary Drinking Water Regulations land area over which water flows into the river, lake, or reservoir; not just the part of the river or lake that you can see

  • Non-enforceable guidelines

  • Focuses on cosmetics and aesthetics of water


Major components to the sdwa
Major Components to the SDWA land area over which water flows into the river, lake, or reservoir; not just the part of the river or lake that you can see

  • EPA sets standards to help ensure consistent quality in our Nations water supply.

  • Contaminants are prioritized by Risk along with Cost Benefit Analysis

  • National Primary Drinking Water Regulations set enforceable maximum contaminant levels & require ways to treat water to remove contaminants


Enforcement
Enforcement land area over which water flows into the river, lake, or reservoir; not just the part of the river or lake that you can see

  • Public notice requirements

  • State enforcement

  • EPA enforcement

  • Citizen suits


Consumer confidence reports ccr
Consumer Confidence Reports (CCR) land area over which water flows into the river, lake, or reservoir; not just the part of the river or lake that you can see

Some information gathered in reports include:

  • Identification of source water

  • Information on detected contaminants

  • Violations of requirements

  • Explanations of variances/exemptions

  • Explanation of expected contamiants


Funding to the states
Funding to the States land area over which water flows into the river, lake, or reservoir; not just the part of the river or lake that you can see

  • The EPA provides grants to implement state drinking water programs

    • Small water systems get special consideration because of their limitations on financing system improvements and monitoring.
