Arsenic Health Effects Research
The Environmental Protection Agency (EPA), American Water Works Association Research Foundation (AWWARF), and Association of California Water Agencies (ACWA) are jointly requesting grant and contract applications for research on human health effects associated with low level arsenic exposure via ingestion. The Safe Drinking Water Act Amendments of 1996 directed EPA to develop a comprehensive study plan to reduce the uncertainty in assessing health risks associated with exposure to low levels of arsenic. This request for applications (RFA) will provide some of the early research in support of that plan. Congress also directed EPA to propose a revised arsenic standard by January 1, 2001. When issuing National Primary Drinking Water Regulations, Section 1412(b)(3)(A) of the amendments specify that EPA use the best available, peer-reviewed science and supporting studies conducted in accordance with sound and objective scientific practices.
While there are several possible approaches to improving our understanding of arsenic risks, additional data on the baseline exposure, metabolism of arsenic, mechanisms of arsenic carcinogenesis, and early endpoints of arsenic toxicity in human populations are key research priorities. Exposure data on arsenic from dietary sources other than drinking water will help determine the relative significance of arsenic exposures from drinking water and aid in comparisons of current United States (U.S.) arsenic exposures with exposure levels at which human health effects have been observed. Understanding the mechanism of arsenic carcinogenesis, the variability in arsenic metabolism, and early endpoints of arsenic toxicity may ultimately contribute to determining the shape and slope of dose-response curves, including possible linear or nonlinear effects, and reduce the uncertainty in these curves.
Risk management policies for arsenic in the U.S. have changed with increases in knowledge, as evidenced by EPAs divergent guidance for arsenic under the Safe Drinking Water Act and the Clean Water Act. EPAs drinking water standard, or maximum contaminant level (MCL), of 50 µg/l was developed by the Public Health Service in the mid-1940s. In 1980, EPA established a human health water quality criterion for arsenic at 0.018 µg/l for a one in a million (10-6) cancer risk level under the Clean Water Act. Researchers have since developed a substantial amount of data (toxicologic, epidemiologic, and some mechanistic) about the potential human health effects of arsenic following ingestion.
The EPAs 1988 Special Report on Ingested Inorganic Arsenic: Skin Cancer; Nutritional Essentiality (EPA/625/3-87/013) developed a risk assessment for arsenic based on existing data. This document has undergone peer review, inside and outside the Agency. The risk assessment addressed the strengths and weaknesses of the database and identified several areas of uncertainty. Given existing human exposure to low levels of arsenic in the U.S., the high costs associated with reducing the level of arsenic in drinking water systems, and specific legislative requirements, additional research on arsenic is warranted. As part of this effort, this RFA encompasses several areas where additional research may contribute to a fuller understanding of arsenics risk and to reduction of uncertainties in the risk assessment.
Principal Areas of Interest in This RFA
The four research areas presented below provide opportunities for exposure, human health, tissue, and animal research. Proposals may address one or more than one research area, and supplements to existing human studies are encouraged. Large-scale epidemiology studies of arsenics chronic health effects are not included under this RFA due to limited available funds. Ongoing epidemiological feasibility studies being funded by EPA and AWWARF, among others, may lay the groundwork for future epidemiological investigations. However, proposals for studies with human participants are appropriate under each of the four research areas.
1. Contribution of Arsenic From Dietary Sources
In order to understand the possible health impacts of exposure to arsenic from drinking water ingestion, it is important to know the relative contributions from different media. Since air exposures typically are low, the amount and variability of exposures from food and beverages need to be quantified for various populations, taking into account demographic variabilities. This could be done by using techniques such as market-basket surveys and duplicate diet surveys for U.S. populations. At a minimum, such surveys need to distinguish between inorganic and organic arsenic. In conducting these studies it is also desirable to address bioavailability of arsenic absorption from ingested foods. Information on specific food sources should be determined in addition to total dietary contributions.
2. Arsenic Metabolism
Further characterization of arsenic metabolism in humans would strengthen the arsenic risk assessment. Two distinct, but related, needs are improved characterization of dose dependency in arsenic metabolism and characterization of the interindividual and intraindividual variability in human populations. Metabolic indicators and biomarkers of exposure (such as urinary arsenic measurements) may fluctuate substantially from day to day. Accordingly, a quantitative evaluation of the impact of such fluctuations is key to the interpretation of the biomarker data. For these studies to be interpretable, total exposures from various sources should be considered. Studies of the dose response for arsenic metabolism should examine exposure levels ranging from those received by high-dose groups to the lower levels typical of the U.S. population. Included in this area are studies to improve mass balance data for differing chemical forms of arsenic at various doses. With regards to population variability, studies could investigate variations in metabolism or other factors affecting human susceptibility to arsenic that might be associated with exposure, genetic factors, age, sex, nutritional status, etc.
3. Mechanisms of Arsenic Carcinogenesis
A mechanistic understanding of carcinogenesis would facilitate a fuller qualitative and quantitative understanding of cancer risks. In order to understand how arsenic causes cancer, it is necessary to have model biological systems relevant to humans. Data collected at the molecular, cellular, tissue, animal, and epidemiological level can contribute to an understanding of arsenic carcinogenesis. As scientific information about arsenic risk is based on direct observations of human tumors, it is particularly important for mechanistic research to establish how findings in any model biological system would relate to human carcinogenesis. Understanding of mechanisms may also be useful in the identification of biomarkers for developing dose-response relationships and for detecting human populations sensitive to arsenic.
4. Early Endpoints of Arsenic Effects in Humans
Studies to characterize early endpoints of arsenic-associated pathology would enhance knowledge of the effects of low doses of arsenic in human populations. These studies should consider dose-response patterns, with an emphasis on effects at low doses. Specific effects that could be addressed in prevalence studies include hyperkeratosis, neurological effects, and other endpoints. Investigators should state the statistical power anticipated by their proposed research given the number of people surveyed and endpoints investigated. Total exposure to relevant chemical forms of arsenic is also an important factor in study design.
Funding for this joint solicitation is provided by the U.S. EPA, AWWARF, and ACWA for a total of approximately $3 million. Any proposal submitted will be considered for an EPA grant or AWWARF contract, unless the proposal stipulates otherwise. EPA will fund approximately $2 million worth of grants, and AWWARF/ACWA will fund approximately $1 million worth of contracts. Recipients will be funded entirely by one agency or the other. It is expected that three to six applications, each with a project period of up to 3 years, will be funded under this joint solicitation.
Academic and not-for-profit institutions located in the U.S. and state or local governments are eligible under all existing EPA authorizations. Profit-making firms are not eligible to receive assistance from EPA under this program, but are eligible to receive funding from AWWARF. Researchers in federal agencies other than EPA may submit applications, but federal employees may not request salary reimbursement. Federal employees may cooperate or collaborate with other eligible applicants within the limits imposed by applicable legislation and regulations.
Researchers who are late in any ongoing AWWARF-sponsored studies without an approved no-cost extension will not be eligible for funding by AWWARF; however, they may be eligible for funding by EPA. Potential applicants who are uncertain of their eligibility for an AWWARF contract should contact their AWWARF project manager.
AWWARF and EPA have a policy of nondiscrimination and abide by all laws, rules, and executive orders governing equal employment opportunity. All entities receiving funding under this solicitation will be required to agree not to discriminate on the basis of age, sex, race, religion, color, national origin, disability or veteran status. AWWARF expects its contractors to be equal opportunity employers who accept the goal of having a workforce that generally reflects the minority composition of the community in which it is located. It is the policy of AWWARF to encourage proposals from qualified minority owned or directed institutions.

Review and Selection
All applications are initially reviewed by EPA to determine their legal and administrative acceptability. Acceptable applications are then reviewed by an appropriate technical peer review group. This review is designed to evaluate each proposal according to its scientific merit. Each review group is composed of non-EPA scientists who are experts in their respective disciplines and are proficient in the technical areas they are reviewing. The reviewers use the following criteria to help them in their reviews:
1. Technical Merit. The originality and creativity of the proposed research, the potential contribution the proposed research could make to advance scientific knowledge about the human health effects of arsenic at low levels in drinking water, the appropriateness and adequacy of the research methods proposed, and the appropriateness and adequacy of the Quality Assurance Narrative Statement will be assessed. Is the research approach practical and technically defensible? Is the proposal well prepared with supportive information that is self explanatory and understandable? Will the research contribute to improving the scientific knowledge base for the risk assessment of arsenic?
2. Investigators. The qualifications of the principal investigator(s) and other staff, including knowledge of pertinent literature, experience, and publication records as well as the probability that the proposed research will be successfully completed will be assessed. Will all key personnel contribute a significant time commitment to the project?
3. Facilities/Equipment. The availability and/or adequacy of the facilities and equipment proposed for the project will be assessed. Deficiencies that may interfere with the successful completion of the research will be identified.
4. Responsiveness. The responsiveness of the proposal to the research needs set forth in the solicitation will be assessed.
5. Budget. The reviewers will be asked to evaluate whether the project can be performed within the time period and with the proposed effort. Although budget information is not used by the reviewers as the basis for their evaluation of scientific merit, the reviewers are asked to provide their view on the appropriateness and/or adequacy of the proposed budget and its implications for the potential success of the proposed research. Input on requested equipment is of particular interest.
All proposal evaluation records will be forwarded for review by staff and named representatives of EPA, AWWARF, and ACWA. Proposals considered for funding will be subject to a relevancy review. The purpose of the relevancy review is to develop a balanced research agenda to advance the understanding of the health effects of arsenic at low levels in drinking water. The following criteria will further define which proposals should be selected for funding:
(1) Which studies have the greatest potential to strengthen the scientific basis for risk assessment/risk management of arsenic in drinking water?
(2) Which studies have the greatest potential to provide a focus for future arsenic health effects research?
(3) Do any of these studies duplicate ongoing research?
A summary statement of the scientific review of the proposal will be provided to each applicant. Funding decisions are the sole responsibility of the organization funding the project. Grants and contracts are selected on the basis of technical merit, relevancy to the research priorities outlined, program balance, and budget.
By submitting an application in response to this solicitation, the applicant grants EPA permission to share the application with technical reviewers both within and outside of the Agency. Applications containing proprietary or other types of confidential information will be returned to the applicant without review.
The funding mechanism for all awards issued under this solicitation will consist of grants from EPA and contracts from AWWARF and depends on the availability of funds. In accordance with Public Law 95-224, the primary purpose of a grant is to accomplish a public purpose of support or stimulation authorized by Federal statute rather than acquisition for the direct benefit of the Agency. In issuing a grant agreement, EPA anticipates that there will be no substantial EPA involvement in the design, implementation, or conduct of the research funded by the grant. However, EPA will monitor research progress, based in part on annual reports provided by awardees.
The mission of AWWARF is to "advance the science of water to improve the quality of life." Contracts with AWWARF are managed by an assigned AWWARF project manager and a volunteer Project Advisory Committee (PAC). PACs are organized by AWWARF for each funded project to provide guidance, review all reports and significant materials, and generally monitor project performance in behalf of AWWARF and the water utility industry. Periodic reports for AWWARF are required every four months. In addition, a final report and intellectual property rights as outlined in the "Standard AWWARF Funding Agreement" are required under all AWWARF contracts. The "Standard AWWARF Funding Agreement" is available on the AWWARF home page at http://www.awwarf.com. For general information regarding the "Standard AWWARF Funding Agreement," contact Kathy Garretson at 303-347-6118 or by E-mail at email@example.com.
