Contamination of drinking water occurs despite strict regulations, yet few studies
have been conducted to assess the public's perception of risk about drinking water.
The purpose of this study was to assess risk perception associated with drinking water
supplied by small water systems and to determine alternative measures that people...
Excessive nitrates in drinking water pose a human health threat, especially to infants. Methemoglobinemia, or blue-baby syndrome, is a potentially fatal condition that inhibits the ability of red blood cells to bind and transport oxygen. Nitrates/nitrites have also been linked to such conditions as cancer, birth defects, and behavioral and...
The purpose of this study was to; (1) determine the extent of well water contamination with nitrate and pesticides, and to understand the relationships among nitrate, pesticide, dissolved chloride, dissolved sulfate, well age, and well depth in the southern Willamette Valley, Oregon; and, (2) to investigate local residents' perceptions and...
The present study was conducted as a three part investigation to
(i) examine the incidence, distribution and kinds of standard plate
count bacteria present in chlorinated and raw water; (ii) study the
ecological role and possible health significance of Aeromonas spp.
in distribution water, and (iii) evaluate the effects of...
Assume clear and cold streams, lakes, or
springs are contaminated and treat appropriately
before drinking from them.
• Wash fruits and vegetables only in safe/treated
water.
• Use safe/treated water to make instant
puddings, gelatin, and other uncooked foods.
• Avoid using snow to make icy drinks or ice
cream....
The fate of antimicrobials entering the aquatic environment is an increasing concern for researchers and regulators, and recent research has focused on antimicrobial contamination from point sources, such as wastewater treatment facility outfalls. The terraccumulation of antimicrobials and mobility in diffuse pollution pathways should not be overlooked as a contributor...
The Safe Drinking Water Act ensures that public systems provide water that meets health standards. However, no such protection exists for millions of Americans who obtain water from private wells. Concern for safety is warranted as most wells draw from underground aquifers, and studies demonstrate that groundwater is affected by...
