With a mandate for a more effective way to protect and clean the nations water resources, the federal government responded with the 1972 passage of the Federal Water Pollution Control Act Amendments, better known as the Clean Water Act (CWA). In 1974, the Safe Drinking Water Act (SDWA) created the first mandatory national program to protect public health through drinking water safety. Despite litigation and controversy throughout their existence, the CWA and SDWA were groundbreaking and remain a centerpiece for U.S. environmental policy.
The Clean Water and Safe Drinking Water Acts
A study published as part of the EPA's Environmental Technology Verification (ETV) Program verifies the performance of a Fyne Process membrane filtration plant tested on high organic-laden surface water in Barrow, Ark. The plant was able to remove significant levels of organics--precursors to disinfection byproducts such as trihalomethanes (THM) and haloacetic acids (HAA)--producing water that easily met the disinfection byproduct standards set by the EPA's stringent Stage 1 D/DBP Rule.
Consumers want to know if the bottled water they buy is safe. How and why bottled water is regulated is not common knowledge and can be confusing to customers. Bottlers who understand and can explain aspects of water quality, regulations and test results to their customers have a useful sales tool to promote their product.
What lab results mean and how to explain them to customers
The following is the U.S. Environmental Protection Agency's Onsite Wastewater Treatment Systems Special Issues Fact Sheet on Water Softeners. This document supports the WQA's position on softener wastes and the fact that they are not harmful to septic systems.
To remain successful, the water treatment professional should take advantage of advances in in-field testing as well as advances in laboratory analyses. This article describes the shifts in analytical requirements recommended to satisfy consumer desires and promote expansion of the POU/POE water treatment industry.
In-field testing and analysis become responsibility of dealers
In December of 1999, the United States Environmental Protection Agency (EPA) published the National Pollutant Discharge Elimination System (NPDES) Phase II Stormwater rule in the Federal Register. The issuance of the rule started a clock that has had municipalities, and stormwater professionals working to understand and evaluate its implications.
Ohio has cut its program that warns the public about how much and how often pollution-contaminated fish should be eaten.
The Ohio Department of Health abolished its fish-consumption advisory program earlier this month to save $100,000. It's the first Great Lakes state to eliminate the alert, environmentalists said.
Advisories have been based on fish samples collected annually by the Ohio Environmental Protection Agency and Ohio Department of Natural Resources. Fish are tested for pesticides, mercury and other toxic chemicals.
The Water Quality Association (WQA) and the point-of-use/point-of-entry (POU/POE) industry as a whole face the usual list of federal and state regulatory challenges in 2002-2003.
The point-of-use and point-of-entry water treatment industry experienced several changes in standards and regulations.
Editor’s Note: Part 1 of this series provided a timeline for the development of a drinking water standard for arsenic. It also summarized the political and public reactions to the U.S. EPA decision to delay and withdraw the arsenic rule.
Part 2 dealt with human exposure and advances in knowledge concerning human health effects of exposure to arsenic.
Part 3 summarized early data on the occurrence of arsenic in U.S. waters.
