42 USC 300j-18 - Drinking water studies

U.S Code last checked for updates: May 19, 2024

§ 300j–18.

Drinking water studies

(a)

Subpopulations at greater risk

(1)

In general

(2)

Report

(b)

Biological mechanisms

The Administrator shall conduct biomedical studies to—

(1)

understand the mechanisms by which chemical contaminants are absorbed, distributed, metabolized, and eliminated from the human body, so as to develop more accurate physiologically based models of the phenomena;

(2)

understand the effects of contaminants and the mechanisms by which the contaminants cause adverse effects (especially noncancer and infectious effects) and the variations in the effects among humans, especially subpopulations at greater risk of adverse effects, and between test animals and humans; and

(3)

develop new approaches to the study of complex mixtures, such as mixtures found in drinking water, especially to determine the prospects for synergistic or antagonistic interactions that may affect the shape of the dose-response relationship of the individual chemicals and microbes, and to examine noncancer endpoints and infectious diseases, and susceptible individuals and subpopulations.

(c)

Studies on harmful substances in drinking water

(1)

Development of studies

The Administrator shall, not later than 180 days after August 6, 1996, and after consultation with the Secretary of Health and Human Services, the Secretary of Agriculture, and, as appropriate, the heads of other Federal agencies, conduct the studies described in paragraph (2) to support the development and implementation of the most current version of each of the following:

(A)

Enhanced Surface Water Treatment Rule (59 Fed. Reg. 38832 (July 29, 1994)).

(B)

Disinfectant and Disinfection Byproducts Rule (59 Fed. Reg. 38668 (July 29, 1994)).

(C)

Ground Water Disinfection Rule (availability of draft summary announced at (57 Fed. Reg. 33960; July 31, 1992)).

(2)

Contents of studies

The studies required by paragraph (1) shall include, at a minimum, each of the following:

(A)

Toxicological studies and, if warranted, epidemiological studies to determine what levels of exposure from disinfectants and disinfection byproducts, if any, may be associated with developmental and birth defects and other potential toxic end points.

(B)

Toxicological studies and, if warranted, epidemiological studies to quantify the carcinogenic potential from exposure to disinfection byproducts resulting from different disinfectants.

(C)

The development of dose-response curves for pathogens, including cryptosporidium and the Norwalk virus.

(3)

Authorization of appropriations

(d)

Waterborne disease occurrence study

(1)

System

The Director of the Centers for Disease Control and Prevention, and the Administrator shall jointly—

(A)

within 2 years after August 6, 1996, conduct pilot waterborne disease occurrence studies for at least 5 major United States communities or public water systems; and

(B)

within 5 years after August 6, 1996, prepare a report on the findings of the pilot studies, and a national estimate of waterborne disease occurrence.

(2)

Training and education

(3)

Funding
