Goal of the study: This investigation will assess exposure to arsenic and uranium in drinking water from private wells in a number of geographic areas specified in requests from three states—Connecticut, New Mexico, and New Hampshire.

Intended use of the resulting data: The data will inform the state health departments as to whether there is a need for public health intervention activities to reduce exposures, and will support local public health action to improve the quality of water from private wells.

Methods to be used to collect data: The methods used to collect data include telephone interviews to determine eligibility, and face-to-face interviews. Data collection will also involve collection of urine samples from residents and private well water samples to assess arsenic and uranium levels.

The subpopulation to be studied: The subpopulation to be studied comprises adults at least 18 years of age who meet the following criteria: 1) use private wells for drinking water, 2) will allow us to collect water samples from their well and tap, 3) will provide a urine specimen, and 4) agree to answer survey questions. Participants will be enrolled from the geographic area of concern as defined by the requesting agency, specifically: n=100 in Connecticut, n=100 in New Mexico, and n=100 in New Hampshire.

How data will be analyzed: Results will be compared with those from existing surveys (e.g., National Health and Nutrition Examination Survey [NHANES], Behavioral Risk Factors Surveillance System [BRFSS]), EPA’s drinking water standards, and historical environmental sampling where data exist). The urine samples will be analyzed by the CDC National Center for Environmental Health (NCEH), Division of Laboratory Science (DLS).

Justification

A.1. Circumstances Making the Collection of Information Necessary

This data collection is being conducted using the Generic Information Collection mechanism of the Assessment of Potential Exposure from Private Wells for Drinking Water – OMB Control No. 0920-1173, Expiration Date 3/31/2020.

The National Center for Environmental Health (NCEH) is authorized to collect this information under section 301 of the Public Health Service Act: Research and Investigation, 42 U.S.C. § 241.

The Centers for Disease Control and Prevention (CDC) recently supported a study that estimated the total damages of arsenic in private wells to be $9.4 billion dollars annually, half attributed to cancer and half to heart disease mortality (Abt 2014). The literature linking arsenic to adverse health effects is growing, and the work done by Abt (2014) was illustrative in nature. It is important to capture a more precise estimate of exposures in all areas of the United States that have arsenic in ground water. Uranium in drinking water is also of concern because the metal is highly toxic; however, the health effects have not been studied as extensively as those associated with arsenic. Uranium tends to co-occur with arsenic, so we will assess uranium exposure as well as arsenic exposure in areas where exposures haven’t been characterized. Without knowing if private wells are at risk for contamination with arsenic and uranium, states are unable to reach out to households with public health protection efforts, such as information about exposures, filtration devices to limit exposure, etc.

CDC will respond to three states that have requested assistance with assessing potential exposure to arsenic and uranium in drinking water from private wells in areas (one area for each of the three states) where there are no data about arsenic and uranium concentrations in ground water. The new information obtained from these investigations will be the description of exposure to contaminants in drinking water from private wells within a well-defined time period and geographic distribution. This information will be used by the requesting agency (Attachment A – Letters of Collaboration) to target public health intervention activities to reduce exposures.

A.2. Purpose and Use of Information Collection

The purpose of this one-time information collection is to respond to the requests for assistance received from Connecticut, New Mexico, and New Hampshire. The primary target audience is public health practitioners with responsibilities for private domestic wells in their jurisdictions. Our state partners (Connecticut, New Mexico, and New Hampshire) will use data generated by this investigation to geographically target existing and/or planned public heath outreach, education, and intervention activities to reduce exposure to arsenic and/or uranium from private well water.

The subpopulation to be studied comprises adults at least 18 years of age, who use private wells for drinking water; will allow us to collect water samples from their well and tap; will collect a first morning void urine specimen; will complete a three-day food diary, and will agree to answer survey questions during an in-person interview. They will be enrolled from the geographic area of concern as defined by the requesting agency, specifically: n=100 in Connecticut, n=100 in New Mexico, and n=100 in New Hampshire. Participants will respond to a survey (see Table 10.1 for an overview of the question topics).

Without this information, states may miss opportunities to target populations at risk from exposure to arsenic and uranium with programs to reduce or eliminate exposures.

A.3. Use of Improved Information Technology and Burden Reduction

The United States Geological Survey (USGS) reports that they recruit about 30% to 50% of people who receive notification of an upcoming water quality study like this (personal communication, Joe Ayotte, May 2018). Thus, we will send out letters and prepaid postcards to the randomly identified households in the 100 cells (approximately 200 – 300 households) identified in the relevant geographic area in each state to recruit one household per cell, for a total of 100 households per state. We will send letters and prepaid response cards to potential participants’ homes. For those households that respond, we will interview one adult per household to confirm eligibility using a telephone screener, which will eliminate the need for potential participants to travel. We will use a laptop and survey software (Epi Info) to collect survey data. Epi Info employs skip logic to reduce participant burden.

A.4. Efforts to Identify Duplication and Use of Similar Information

As part of the planning process for this investigation, NCEH found that there are no existing data, as determined using United States Geological Survey (USGS) databases, on arsenic and uranium in private wells in the areas defined by the three state requestors.

A.5. Impact on Small Businesses or Other Small Entities

No small businesses will be involved in this information collection.

A.6. Consequences of Collecting the Information Less Frequently

This investigation involves a one-time information collection. There are no legal obstacles to reduce the burden.

A.7. Special Circumstances Relating to the Guidelines of 5 CFR 1320.5

This request fully complies with the regulation 5 CFR 1320.5.

A.8. Comments in Response to the Federal Register Notice and Efforts to Consult Outside the Agency

This data collection is being conducted using the Generic Information Collection mechanism for Assessment of Potential Exposure from Private Wells for Drinking Water – OMB Control No. 0920-1173 (expiration date: 03/31/2020). A 60-day Federal Register Notice was published in the Federal Register, Vol. 81, No. 48 on Friday, March 11, 2016. Four public comments were received. One public request for documents was received.

A.9. Explanation of Any Payment or Gift to Respondents

NCEH will not offer any payment or gift to respondents.

A.10. Protection of the Privacy and Confidentiality of Information Provided by Respondents

This submission has been reviewed by the NCEH Information Systems Security officer who determined that the Privacy Act does apply. The applicable System of Records Notice is SORN No. 09-20-0136, “Epidemiologic Studies and Surveillance of Disease Problems” (Federal Register: December 31, 1992; Volume 57, Number 252; pages 62812-62813) (records retrievable by name and ID number). Information in identifiable form (IIF) will be treated in a secure manner and will not be disclosed, unless otherwise compelled by law.

The following IIF will be available through state private well records: name, mailing address, phone numbers, and latitude and longitude of the respondent’s private well. This information will be stored in electronic form by the requesting entity and will be used to facilitate scheduling interviews and provide test result to respondents. Respondents will be assigned a unique ID number to serve as a link between their identity and their response data, samples, and specimen. All records, including IIF, belong to the requesting agency and will reside on its own established record system. The requesting agency will retain the data according to its own record schedule.

During the investigation and on behalf of the requesting agency, NCEH will have access to the link between the respondent’s IIF and the respondent ID number. Once the investigation ends, NCEH will not have access to IIF. To make the data available to the public, de-identified data will be made available on the USGS ScienceBase platform.

Respondents will be recruited using a letter (Attachment B – Invitation Letter). Prior to administering a questionnaire to potential respondents, a telephone-based screening form will be used to screen potential respondents for interest and eligibility (Attachment C – Screening Survey). Consent to participate in the investigation will be obtained using a paper consent form (Attachment D – Consent Form), which the respondent will read and sign. The consent forms provide the following information: purpose of the data collection, list of activities for respondents, description of risks, data/information disclosure possibilities, description of benefits, compensation, treatment for injury, contacts for questions, and a statement about voluntary participation, refusal, and withdrawal.

The Food & Bathing Log has 28 check boxes to capture specific foods eaten and entries for the time of day and length (in minutes) of each bath or shower they took during the three days before their interview with project staff (Attachment E – Food & Bathing Log). The foods listed, e.g., rice crackers, are those most likely to be contaminated with arsenic or uranium. The instructions for collecting a first morning void urine specimen can be found in Attachment F – Urine Collection Directions. The survey consists of 56 questions that fall under three categories (Attachment G – Survey). Table 10.1 below summarizes the breakdown of questions. The questions about food consumption on the Food & Bathing Log and survey were drawn from instruments used in an ongoing CDC-funded biomonitoring study in New Hampshire and were approved by the IRB of the New Hampshire Department of Health. The questions about bathing are from a previously approved study of arsenic exposure (Assessment of Exposure to Arsenic through Household Water, OMB Control No. 0920-0472, Expiration Date 06/03/2003).

Table 10.1. Overview of question types used on the survey

Question Type for Food Diary	# of Questions Used
Check boxes for foods eaten each day	19
Question Type for Survey
Personal information (date of birth, height, weight, race)	9
Home and household water source	8
Other possible exposures to arsenic or uranium	20

Except for date of birth, height, weight, and questions where the respondent has to specify a place, or number (e.g., number of cups of water per day), the questions will have yes/no/don’t know/refused responses.

Urine specimens and environmental samples (well water, tap water), will be collected to test for arsenic and uranium. Urine specimens will be tested by the Division of Laboratory Sciences laboratories at NCEH. Water samples will be tested by the laboratories at USGS. All records and specimens will be coded with respondent ID number only. The laboratories will not store clinical specimens or environmental samples for future research; any unused samples will be discarded at the completion of the testing.

After the investigation team completes its field data collection, the requesting agency will have the discretion to share de-identified data labeled only with respondent ID with NCEH for continued support with statistical analysis and report writing. Findings of the investigation will include summary data only and may be reported as state or local agency reports; Morbidity and Mortality Weekly Report or journal articles; media reports; or presentations to the community, responders, and to public health practitioners at local, regional, and national conferences. Study participants will be provided a copy of their test results (Attachment H – Participant Results Letter).

All de-identified records maintained by NCEH after the investigation will be subject to the CDC Records Control Schedule (CRCS) which contains authorized disposition instructions for administrative and program records. NCEH is legally required to maintain its program-related records in accordance with CRCS disposition instructions. For example, research records (datasets, field records, and other information necessary to understand a research project) may have implications or usefulness for future scientific investigations. These records must be maintained for at least eleven years, but no longer than twenty years, depending upon program needs for scientific, legal, or business reference. Transfer to Federal Records Center is authorized in accordance with Code of Federal Regulations storage regulations of electronic records.

These retention periods have a direct impact on completing Freedom of Information Act requests.

A.11. Institutional Review Board (IRB) and Justification for Sensitive Questions

Federal Regulations for Protection of Human Subjects (45 CFR 46) state that “research means a systematic investigation, including research development, testing, and evaluation, designed to develop or contribute to generalizable knowledge.”

In contrast, this investigation will be undertaken to identify, characterize, and solve a public health problem and the knowledge gained will directly benefit the affected community. Although this investigation is intended to be a systematic investigation, it is not designed to develop or contribute to generalizable knowledge. Human subjects review by an Institutional Review Board (IRB) is not required. This investigation was reviewed the NCEH/ATSDR Human Subjects Coordinator (Attachment I – Research Determination Form).

Some of the NCEH investigation respondents may find some of the questions asked during an investigation, such as race/ethnicity, to be sensitive. The responses to these questions, if asked, are needed to assess health risks from drinking water provided by private wells.

Social security numbers are not needed nor will they be requested.

A.12. Estimates of Annualized Burden Hours and Costs

The estimated burden to respondents is summarized in Table 12.1 below. USGS reports that they recruit about 30% to 50% of people who receive notification of an upcoming water quality study like this (personal communication, Joe Ayotte, May 2018). Thus, we will send out letters and prepaid postcards to the identified households in the 100 cells (approximately 200 – 300 households) in each state to recruit one household per cell for a total of 100 households per state. We anticipate that 40% of households receiving notification of our study will complete the Response form (part of the Screening Survey, Attachment C) and send it back to us. We estimate that 80% of those who respond to our invitation letter will be eligible. The study participants (household members) will participate in our study one time for approximately 75 minutes (note that the water samples will be collected by study staff, not by study participants):

The total annualized time burden to respondents is estimated at 450 hours.

Table 12.1: Estimated Annualized Burden to Respondents

Type of Respondents	Form Name	No. of Respondents	No. of Responses per Respondent	Average Burden per Response (in hours)	Total Burden Hours
Adults at least 18 years old using a private well for tap water	Screening Survey	400	1	30/60	200
	Response Form – Permission to Collect a Well Water Sample	300	1	5/60	25
	Food & Bathing Log	300	3	5/60	75
	Survey	300	1	30/60	150
TOTAL					450

Table 12.2 presents the total respondent costs using the mean hourly wage for the general public. Hourly mean wage information is from the U.S. Department of Labor's Bureau of Labor Statistics, using the 2017 National Occupational Employment and Wage Estimates for the United States (https://www.bls.gov/oes/current/oes_nat.htm#00-0000). Since this data collection will include respondents from the general public, an average rate for all occupations, or $24.34 per hour, is used. The total estimated annualized respondent cost is $10,953.00. The total respondent costs are summarized in Table 12.2 below.

Table 12.2: Estimated Annualized Burden Costs

Type of Respondents	Form Name	No. of Respondents	No. Responses per Respondent	Avg. Burden per Response (in hours)	Total Burden Hours	Hourly Wage Rate	Total Respondent Costs

A.13. Estimates of Other Total Annual Cost Burden to Respondents or Record Keepers

There are no direct costs to the participants other than their time to participate in this investigation.

A.14. Annualized Cost to the Federal Government

The estimated average annual cost to the federal government for the proposed information collection activities is $324,060. This figure encompasses 20% FTE of one GS-14 employee, 20% FTE of 4 GS-13 employees, and information collection contract costs (Interagency Agreement with USGS). The average hourly rate was obtained from the Office of Personnel Management’s website (http://www.opm.gov/oca/09tables/html/atl_h.asp). The annual rates for a GS-14 and GS-13 in Atlanta, GA are about $113,000 and $98,000, respectively, per year. The contractual cost for an information collection with partners (e.g., the development of a screener and questionnaire, participant recruitment, and final reports) is estimated at $152,010. See Table 14.1 for details.

Table 14.1: Estimated Annualized Cost to the Government per Activity and Total

Cost Category	Estimated Annualized Cost
Federal employee costs for information collection (60% FTE of 1 GS-14 at $113,000/year, 60% FTE of 4 GS-13 at 98,000/yea,15% of GS-15 at 160,000/year, travel funds)	$172,050
Contractual costs for this information collection (IAA with USGS) Potential study participant identification, recruitment, appointments Field work (including travel expenses), data analysis, final report) Environmental sample or clinical specimen collection and analysis	$152,010
Total cost per year	$324,060
