Environmental pollution concerns come to forefront
Reports that the province finds El Dorado Irrigation District & # 8217 ; s imbibing H2O system crude, out-of-date and an avenue for risky pollutants sent El Dorado County occupants scrambling for more information Wednesday.
The message that pregnant, aged and ill occupants should boil their H2O or purchase it bottled was buried in all right print in the 28,000 notices mailed in September to EID clients. Tonss of occupants called EID offices Wednesday after The Bee obtained a transcript of a province study demoing exposures of manure hemorrhoids, carnal carcases, mats of algae and other contaminations in and near EID & # 8217 ; s unfastened reservoirs.
& # 8220 ; That article made me a house believer that I & # 8217 ; m non brainsick, & # 8221 ; said Sue Reimer, who was seven months pregnant in 1996 when she was diagnosed with giardia, a water-borne virus that causes enteric jobs. The El Dorado applied scientist said she was imbibing merely EID H2O & # 8212 ; and tonss of it, at her physician & # 8217 ; s suggestion.
There & # 8217 ; s no confirmed connexion between EID & # 8217 ; s H2O and unwellness in El Dorado County, county functionaries say.
The job at EID, province wellness functionaries say, is that after the territory filters H2O drawn from the American River, it shops the H2O in little reservoirs unfastened to the elements.
Most other H2O territories use closed steel or concrete armored combat vehicles. Merely a few other California H2O territories presently store treated H2O in unfastened reservoirs, including those in McCloud, Santa Barbara, Montecito, Carpinteria and Los Angeles. None of those has every bit many as the 11 used in EID.
The El Dorado reservoir H2O systematically meets province wellness criterions on bacteriums, EID functionaries say, because the territory invariably bubbles Cl from nearby armored combat vehicles into the reservoirs and sends the H2O on to places. But they admit their unfastened reservoirs expose the H2O to taint by disease-causing agents for which there are no wellness criterions or required testing in little H2O territories: giardia, viruses and cryptosporidium.
& # 8220 ; We are more vulnerable because they are non covered, & # 8221 ; said Marjie Lopez Read, EID H2O quality overseer, & # 8220 ; even though the intervention is complete at the H2O plants. & # 8221 ;
William Hetland, EID general director, said the territory hasn & # 8217 ; t ignored the job of covered reservoirs. Several old ages ago, he said, it began purchasing rubberized membrane screens for the reservoirs. Seven had already been installed when, in July, the California Department of Health Services ordered the territory to either construct steel armored combat vehicles or set concrete palpebras on all of its reservoirs. The gum elastic covers, the province decided after a 1997 probe, let excessively much taint of treated H2O by animate beings, flora and rain.
& # 8220 ; We & # 8217 ; ve been turn toing this job, & # 8221 ; said Hetland. & # 8220 ; Possibly non every bit fast as they & # 8217 ; vitamin D like, but we have been turn toing the problem. & # 8221 ;
Until 1990, he said, the territory didn & # 8217 ; t even filtrate its H2O. It merely pumped American River H2O to the reservoirs and treated it with Cl.
The province put EID on a four-year agenda to cover its reservoirs, a occupation that EID board member Raymond Larsen estimated would be $ 30 million to $ 40 million and coerce the territory, with an one-year H2O supply budget O
f $ 10 million, to raise rates 50 per centum.
The province besides ordered the territory to rede clients that if they & # 8217 ; re aged, pregnant, sick, HIV-positive, undergoing malignant neoplastic disease therapy or otherwise enduring from a compromised immune system, they should either utilize bottled H2O or boil their H2O.
A flyer titled & # 8220 ; EID News from the Water Front & # 8221 ; was mailed to all clients and sent place with school kids, Hetland said.
But several occupants said they either didn & # 8217 ; t detect it or didn & # 8217 ; t recognize its significance. The warning about boiling H2O appeared on the 3rd page.
& # 8220 ; I ne’er saw this notice, & # 8221 ; said resident Reimer. & # 8220 ; I ever look. & # 8221 ;
To endorse up its enforcement order, the Department of Health Services prepared a vividly photographed study that didn & # 8217 ; t go around much beyond the EID board of managers. It shows bird dungs, dead toads and birds, beer bottles, the footmarks of human swimmers, overflow from Equus caballus and cattle grazing lands and carnal skeletons in the reservoirs.
& # 8220 ; If an septic cow, while croping, defecates into the imbibing H2O stored in this reservoir, & # 8221 ; states the caption to one exposure in the study, & # 8220 ; the H2O becomes contaminated with literally 1000000s of Cryptosporidium organisms. & # 8221 ;
Water quality experts say Cl does non kill cryptosporidium, an enteric parasite that was responsible for an eruption that infected 400,000 people in 1993 in Milwaukee. Chlorine by and large kills viruses but does non wholly kill giardia.
El Dorado County wellness functionaries say that so far this twelvemonth they documented six instances of giardia and two of cryptosporidium, some of them from Lake Tahoe, which is non in the EID service country. Those Numberss are no higher than documented in old old ages, they said, and probes normally show that victims have been swimming in rivers or imbibing from watercourses while backpacking.
But Reimer said she hadn & # 8217 ; t been backpacking in five old ages when she got giardia. It made her & # 8220 ; sicker than a Canis familiaris, & # 8221 ; excessively sick to even care for her 2-year-old for two hebdomads.
& # 8220 ; I lost 10 lbs and I got to the point where I was holding contractions, & # 8221 ; she said. & # 8220 ; I called EID and said the lone H2O I drank is your H2O. How did I acquire giardia? They said we treat all our H2O. & # 8230 ; They told me I was crazy. & # 8221 ;
Other EID clients say they & # 8217 ; re regular drinkers of bottled H2O.
& # 8220 ; We haven & # 8217 ; t imbibe any of that H2O for four or five old ages, & # 8221 ; said Wave Baxter of Diamond Springs, whose food markets at a Placerville Lucky shop included a big bottle of H2O. & # 8220 ; The last clip I set a glass on the container and turned around to look the underside was full of sand. & # 8221 ;
But board member Larsen, who lives in Camino, said he drinks the H2O with no scruple.
& # 8220 ; I know the images are instead in writing but if you go out to most of these reservoirs it looks nil like the images, & # 8221 ; said Larsen. & # 8220 ; We have fencings around these things. We can & # 8217 ; t maintain ducks out, of class, but there are safeguards taken so that if e coli ( bacteriums ) does acquire into the system, the Cl is added as it leaves the reservoir to work out that possible threat. & # 8221 ;
EID & # 8217 ; s H2O system, centered around Sly Park Reservoir, was built in the 1950s by the U.S. Bureau of Reclamation for imbibing H2O and agricultural usage.
