A precautionary boil notice was earlier issued after E-coli was found at 443 postcodes
Tap water in thousands of Kent and Surrey homes has been deemed safe to drink following the lifting of a precautionary boil notice.
On Friday, SES water advised customers to boil all drinking water after the deadly E-coli bacteria was discovered during routine tests.
Teams were immediately called to restore the water supplies to their normal standards which has now been achieved.
Four towns on the South Coast of Massachusetts are under a boil water order after E. coli was detected in their water source.
The Mattapoisett River Valley Water District sent out the order on Wednesday, saying it was notified of the positive E. coli results in routine samples collected Tuesday, WCVB reported. The boil water order affects Mattapoisett, Fairhaven, Rochester, and Marion.
Per the order, any ice, drinks, formula, and uncooked foods prepared with water on or before Tuesday should be discarded, WCVB reported. The district has begun temporary chlorination of the water and will flush the system over the next few days. More samples will be collected Thursday, and residents will be informed when tests show no E. coli is present.
People in parts of Surrey are being told to boil their water before drinking it over fears it could contain E. coli.
Hundreds of postcodes in the Oxted area have been affected.
SES Water said an issue was discovered during routine tests, and “our teams are working to investigate the problem and restore supplies to their usual high standards”.
The scale of the contamination has not yet been confirmed.
The water company is awaiting further test results.
In the meantime people in the area are being told to boil all water and let it cool before using it for drinking, preparing food or cleaning their teeth.
Pets should also be given boiled tap water.
Boiled water can be kept in the fridge, and should be covered and used within 24 hours.
More than 1,200 water users in Valencia County have been asked to boil their water after E. coli bacteria was discovered in a routine sample.
These customers receive their water from Monterey Water Company. The New Mexico Environment Department instructed the utility to issue a boil water advisory on Oct. 2, according to a press release.
E. coli is commonly found in the intestines of both humans and other animals and NMED states that the bacteria’s presence in water indicates that it may have been in contact with sewage or animal waste.
A sample that tests positive for the bacteria can indicate the presence of dangerous strains of E. coli or other organisms that can cause water-borne illness, the press release states. Symptoms of water-borne illnesses include gastrointestinal problems and, in rare instances, these illnesses can be deadly. Sensitive populations including children, senior citizens and people with compromised immune systems have increased risk of contracting these illnesses.
When a boil water advisory is issued, the customers in the affected area are encouraged to boil their water for three minutes prior to drinking it or using it to make coffee, tea, other drinks or ice. The water should also be boiled before using it for cooking, washing fruits and vegetables or brushing teeth. Additionally, residents should boil the water before using it to prepare infant formula or to provide drinking water to pets.
The boil water advisory only affects customers who receive water from Monterey Water Company. Other surrounding areas are not impacted.
Boil water advisories usually last for a few days. For example, residents in the Lovington area were under a boil water advisory for approximately three days in January after E. coli was found in the Lovington Municipal Water Supply.
Monterey Water Company is a privately-owned water utility that has been serving customers in Valencia County since the 1980s. The company was formed to provide water to Monterey Mobile Home Estates and Monterey Park units two and three. These subdivisions are located southeast of Los Lunas.
The utility has two active wells that it uses for groundwater and does not use any surface water.
This is not the first time that E. coli has been detected in the Monterey Water Company’s system. According to the New Mexico Drinking Water Bureau’s Drinking Water Watch database, E. coli was also detected in 2020 and in 2014.
Research – Is Fresh Produce in Tigray, Ethiopia a Potential Transmission Vehicle for Cryptosporidium and Giardia?
In rural Ethiopia, where people often share their homes with their livestock, infections of humans and animals with Cryptosporidium and Giardia are relatively common. One possible transmission route is consumption of contaminated fresh produce; this study investigated the occurrence of Cryptosporidium and Giardia in fresh produce in four districts of rural Tigray in Ethiopia. Fresh produce samples (n = 55) were analysed using standard laboratory procedures. Overall, 15% (8/55) of samples were found to be contaminated. Although contamination levels were mostly low, a few samples had high numbers of Giardia cysts (up to around 70 cysts per 30 g sample). Molecular analyses were largely unsuccessful, but Giardia Assemblage A was identified in one sample. Contamination with these parasites was identified in two of the four districts, but, although a similar pattern has already been described for water contamination, this may be at least partially explained by sampling bias. Nevertheless, we speculate that access to clean water sources may be an important factor for reducing the occurrence of these pathogens. Given the public health and veterinary burden associated with both parasites, the factors which are of importance for their circulation in the communities and environments deserve further investigation.

WASHINGTON – The District has issued a Boil Water Advisory for portions of the Northeast due to the possibility of elevated levels of E. coli/coliform bacteria.
The advisory was issued Thursday and includes the neighborhoods of Edgewood, Brookland, Fort Lincoln, Woodridge, Queens Chapel, Michigan Park and North Michigan Park. Officials say approximately 14,000 residents have been affected.
The impacted region is approximately:
– East of North Capitol Street
– West of Eastern Avenue
– South of New Hampshire Avenue
– North of New York Avenue
Research – Use of Oxidative Stress Responses to Determine the Efficacy of Inactivation Treatments on Cryptosporidium Oocysts
Cryptosporidium oocysts are known for being very robust, and their prolonged survival in the environment has resulted in outbreaks of cryptosporidiosis associated with the consumption of contaminated water or food. Although inactivation methods used for drinking water treatment, such as UV irradiation, can inactivate Cryptosporidium oocysts, they are not necessarily suitable for use with other environmental matrices, such as food. In order to identify alternative ways to inactivate Cryptosporidium oocysts, improved methods for viability assessment are needed. Here we describe a proof of concept for a novel approach for determining how effective inactivation treatments are at killing pathogens, such as the parasite Cryptosporidium. RNA sequencing was used to identify potential up-regulated target genes induced by oxidative stress, and a reverse transcription quantitative PCR (RT-qPCR) protocol was developed to assess their up-regulation following exposure to different induction treatments. Accordingly, RT-qPCR protocols targeting thioredoxin and Cryptosporidium oocyst wall protein 7 (COWP7) genes were evaluated on mixtures of viable and inactivated oocysts, and on oocysts subjected to various potential inactivation treatments such as freezing and chlorination. The results from the present proof-of-concept experiments indicate that this could be a useful tool in efforts towards assessing potential technologies for inactivating Cryptosporidium in different environmental matrices. Furthermore, this approach could also be used for similar investigations with other pathogens. View Full-Text
FOLLOWING advice from the Health Service Executive, Irish Water and Mayo County Council have issued a boil water notice for the area supplied by the Clare Island public water supply to protect approximately 165 people following a recent drinking water quality test.
The notice has been put in place due to the detection of cryptosporidium in the Clare Island public water supply.
Cryptosporidium is a tiny parasite found in human and animal waste. If it is swallowed (ingested), it can cause a disease called cryptosporidiosis. The symptoms of cryptosporidiosis include fever, stomach upset, weight loss and diarrhoea.
Cryptosporidium may be found in water if it has been contaminated or if there has been a problem with water treatment.
Legionella spp. and other opportunistic premise plumbing pathogens (OPPPs), including Pseudomonas aeruginosa, Mycobacterium avium, Stenotrophomonas maltophilia, and Acinetobacter baumannii, are normal inhabitants of natural waters, drinking water distribution systems and premise plumbing. Thus, humans are regularly exposed to these pathogens. Unfortunately, Legionella spp. and the other OPPPs share a number of features that allow them to grow and persist in premise plumbing. They form biofilms and are also relatively disinfectant-resistant, able to grow at low organic matter concentrations, and able to grow under stagnant conditions. Infections have been traced to exposure to premise plumbing or aerosols generated in showers. A number of measures can lead to reduction in OPPP numbers in premise plumbing, including elevation of water heater temperatures.
