UCMR History and Background

Unregulated Contaminant Monitoring Rule (UCMR)

Part of The Safe Drinking Water Act (SDWA) of 1996

Requires that once every five years, a new list of < 30 unregulated contaminants be monitored by Public Water Systems (PWS)

UCMR 1 – September 17, 1999

UCMR 2 – January 4, 2007

UCMR 3 – May 2, 2012

2

Why was UCMR Developed?

Based on occurrence and health risk factors

Developed in coordination with the Contaminant Candidate List (CCL).

CCL is a list of contaminants not regulated by the National Primary Drinking Water Regulations

3

UCMR 3 Requirements

UCMR 3 requires PWS to monitor for 28 chemicals and 2 viruses

under each of the following lists

Assessment Monitoring (List 1 Contaminants)

Screening Survey (List 2 Contaminants)

Pre-Screen Testing (List 3 Contaminants)

Associated inorganic methods: 200.8 Rev. 5.4, ASTM D 5673-10, Standard Methods 3125, excluding Cr 6+

4

Assessment Monitoring

Common methods for drinking water labs

All PWS serving more than 10,000 people

800 representative labs serving less than 10,000 people

Will monitor for 21 List 1 contaminants during a period from January 2013 to December 2015

5

Screening Survey

Using methods not common for drinking water labs

PWS serving more than 100,000 people

320 representative labs serving 10,000 to 100,000 people

480 representative labs serving less than 10,000

7 List 2 contaminants from January 2013 to December 2015

6

Pre – Screen Testing

Uses newer technology not common in most drinking water labs

800 representative PWS serving less than 1000 people that do not disinfect

These are PWS with wells in areas of Karstor or fractured bedrock

2 contaminants from List 3 viruses

7

UCMR 3 EPA Lab Approval Program

Labs must complete and submit for method specific application packages

Results will be under review from the EPA

Approved labs will be eligible for PT testing

Successful labs will be granted approval

EPA will pay for all samples tested

8

UCMR 3 Approved Labs

For a complete listing of the UCMR3 laboratories please visit the USEPA website at http://www.epa.gov and search for UCMR3.

As of December 27, 2012 , 53 laboratories were listed as approved

Only the labs approved for 200.8 have been listed on the previous slides. The remainder of the labs are approved for other methods.

Summary of UCMR 3 EPA Methods

13

Analysis UCMR 3 EPA Methods

Six metals:

V, Mo, Co, Sr, Cr, Cr6*

200.8 Rev 5.4

Volatile Organics 524.3

Synthetic Organic

Compound

522

Cr 6

218.7

Chlorate 300.1

Perfluorinated

Compounds

537 Rev 1.1

Hormones 539

Viruses 1615

Cr6 method is separate from 200.8. If total Cr is <limit, speciation is not required

IDC Performance Criteria

Initial Demonstration of UCMR 3 Capability (IDC)

Can be found in Section 5 of the EPA UCMR 3 Laboratory Approval Requirements and Information Document – Version 2.0, January 2012

Low system background

Precision

Accuracy

MRL (Method Required Limits) demonstration

14

Low System Background

Laboratory Reagent Blank (LRB) must be less than 1/3 to 1/2 of the MRL for each analyte. Recommended masses and MRL’s are listed below:

In, Sc, and Tb are the recommended internal standards

15

Mass MRL (ppb)

Cr 52 0.2

Co 59 1.0

Mo 98 1.0

Sr 88 0.3

V 51 0.2

Precision

A Laboratory Fortified Blank (LFB) is prepared

This is typical 0.2 % HNO3 spiked with the five analytes at 2 – 5 times the MRL (listed on the previous slide)

This solution is then run 4 -7 individual times

The % RSD is then calculated and should be <10%

16

Accuracy

Using the data from the precision run, calculate the average recovery

The recovery for each of the analytes should be +/- 15%

17

Minimum Reporting Level (MRL)

Minimum Reporting Levels need to be validated for each of the analytes: Cr, Co, Mo, Sr, and V

18

Calculate the Mean

19

Calculate the Standard Deviation

20

Calculate the Upper and Lower PIR Limits

21

Summary of UCMR3

The UCMR3 is a relatively new EPA methodology that basically has been added to the Safe Drinking water act of 1996.

UCMR3 includes both inorganic and organic contaminants from the CCL found to have heath risks associated with them and are or could be found in drinking water supplies.

All contaminants listed have an associated EPA method that needs to be followed for approval

UCMR3 has different terminology associated with it as well as different ways of numerically validating the data: Noise, precision, accuracy, and MRL’s

Purpose of the presentation was to get familiar with the method, new terminology and validation procedures
