Trace pesticides in treated Oregon
RESTON, VA — Treated drinking water
from Oregon’s Clackamas River contains trace levels of
pesticides, according to results of a recently released
US Geological Survey (USGS) study, in which the
Clackamas River Water Providers and the Clackamas County
Department of Water Environment Services cooperated.
Information on the study, available in the USGS
Scientific Investigations Report 2008-5027, Pesticide
Occurrence and Distribution in the Lower Clackamas River
Basin, Oregon, 2000-2005, was released by the USGS in a
March 18 press release.
The treated drinking water samples were collected from a
drinking water treatment plant that uses the Clackamas
River as a raw water source. One or more of 15
pesticides were detected in nine of 15 samples of
drinking water. According to the USGS, all of the
detections in drinking water were “far below” existing
US Environmental Protection Agency (EPA) drinking water
standards and other human health benchmarks.
The UGGS said its study also found a variety of
pesticides in water samples from the lower Clackamas
River mainstem and tributaries, with more pesticides
detected in the tributaries than the mainstem.
The herbicides atrazine and simazine were the most
commonly detected. High-use herbicides such as
glyphosate and triclopyr/2,4-D, the active ingredients
in RoundUP™ and Crossbow™, respectively, also were
frequently detected, reported the USGS.
Clock is running for old US water pipes
A report from the National Research Council says that a majority of
the 1 million miles of water piping in the US will need to be
replaced within the next 30 years, according to a September 11 story
Environment News Service.
The report linked an increase in waterborne diseases as a potential
result of the corroding water systems and asks the federal
government to fund programs that would better monitor waterborne
contamination in the future, the story said.
The report also calls on the US Environmental Protection Agency to
work with each state to establish programs that will improve and
unify plumbing codes, according to the story.
One problem the report addresses is that current regulatory programs
do not properly address the potential for disease outbreaks or look
at distribution systems as the potential sources of contamination,
the story said.

Crypto found in CA play fountains
SAN JOSE, CA – The Santa Clara County Public Health Department is
monitoring interactive play fountains around the county after seven
children were infected by a Cryptosporidium parasite while playing
in a fountain at Plaza de Cesar Chavez, according to an article in
The Mercury News.
The Plaza de Cesar Chavez fountain and another fountain in McEnery
Park have been shut off, and city officials are expected to meet
this week with representatives from the county to review filtration
systems for removing bacteria from the water, the story said.
Interactive fountains, which are designed for water play,
continuously recirculate water through a series of jets, increasing
the opportunity for contaminants to build up, the report noted.
Unlike public pools, hot tubs, spas and water parks, interactive
fountains are not monitored by health officials for proper
chlorination, according to the article.
