Trihalomethanes are predominantly formed during disinfection of water via reactions of the oxidant with natural organic matter. Even though chlorinated and brominated trihalomethanes are the most widespread organic contaminants in drinking water, when iodide is present in raw water iodinated trihalomethanes can also be formed. The formation of iodinated trihalomethanes can lead to taste and odor problems and is a potential health concern since they have been reported to be more toxic than their brominated or chlorinated analogs. Currently, there is no published standard analytical method for I-THMs in water. The analysis of 10 trihalomethanes in water samples in a single run is challenging because the iodinated trihalomethanes are found at very low concentrations (ng/L range), while the regulated chlorinated and brominated trihalomethanes are present at much higher concentrations (above μg/L). An automated headspace solid-phase microextraction technique, with a programmed temperature vaporizer ...

Nitrifying biofilters degrading the four regulated trihalomethanes (THMs) trichloromethane (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), and tribromomethane (TBM) -were analyzed for the presence and activity of ammonia-oxidizing bacteria (AOB). Biofilter performance and batch kinetic tests performed on biofilm removed during backwashing verified that the biofilters contained organisms capable of degrading the four regulated THMs commonly found in treated drinking water. Quantitative PCR (qPCR) and amoA sequence analysis provided evidence that the Nitrosomonas oligotropha was the only AOB present. N. oligotropha is typically associated with drinking water distribution system AOB communities, and their presence in these biofilters might indicate that their tolerance to THMs is another reason for their dominance in chloraminated drinking water systems. ...

Drinking water disinfection byproducts suggests a possible connection to adverse health effects, including neurological diseases such as Alzheimers, a new study has warned.. University of Illinois scientists report the first identification of a cellular mechanism linked to the toxicity of a major class of drinking water disinfection byproducts.. Im not implying that drinking disinfected water will give you Alzheimers, said Michael Plewa, lead scientist and professor of genetics in the U of I Department of Crop Sciences.. Certainly, the disinfection of drinking water was one of the most significant public health achievements of the 20th century. But the adverse effects of disinfection byproducts (DBPs) that are unintentionally formed during this process are causing concerns as researchers unveil their toxicity.. More than 600 DBPs have been discovered. Although researchers know some DBPs are toxic, little biological information is available on the majority of these water contaminants. The ...

WE ARE required to monitor your drinking water for disinfection byproducts (total trihalomethanes [TTHM] and haloacetic acids-five [HAA5]) every calendar year during warm water temperature months (May-September). Results of regular monitoring are an indicator of whether or not your drinking water meets health standards. During the monitoring period of May 1, 2011 through September 30, 2011, the TREMONT WATER DISTRICT did not monitor for total trihalomethanes (TTHMs) and haloacetic acids-five (HAA5), and therefore we cannot be sure of the quality of your drinking water during that time. This violation occurred because of the failure to collect the required samples for total trihalomethanes (TTHMs) and haloacetic acids-five (HAA5) from the water systems distribution system. Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses).

The Stage 1 Disinfectants and Disinfection Byproducts Rule (DBPR) reduces drinking water exposure to disinfection byproducts. The Rule applies to community water systems and non-transient non-community systems, including those serving fewer than 10,000 people that add a disinfectant to the drinking water during any part of the treatment process.. The Stage 2 DBPR strengthens public health protection by tightening compliance monitoring requirements for Trihalomethanes (TTHM) and Haloacetic acids (HAA5). The rule targets public water systems (PWSs) with the greatest risk.. Taken together, the Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts Rules (DBPRs) improve drinking water quality. The rules do this by providing protection from disinfection byproducts. Byproducts, if consumed in excess of EPAs standard over many years, may increase health risks.. Drinking water comes from source water locations such as:. ...

RESULTS: THM exposures, except for ingestion of ≥6 μg/day of bromodichloromethane (odds ratio [OR]: 1.65 [95% confidence interval (CI): 1.02-2.69]), were not associated with risk of hypospadias. Elevated risk of hypospadias was associated with estimates of consumption of cold tap water at home (OR: 1.71 [95% CI: 1.07-2.76]), total water (OR: 1.70 [95% CI: 1.09-2.67]), bottled water (OR: 1.64 [95% CI: 1.09-2.48]), and total fluid (OR: 1.55 [95% CI: 1.01-2.39]) for the highest versus the lowest categories; the first 2 showed dose-response trends. ...

The potential for generation of disinfection byproducts (DBPs) in swimming pools is high due to the concentrations of chlorine required to maintain adequate disinfection, and the presence of organics introduced by the swimmers. Health Canada set guidelines for trihalomethanes (THMs) in drinking wate …

1) Disinfectant By-products. Chemicals like chlorine, bromine, and iodine are in the class known as halogens (salt-producing), and are frequently used as industrial disinfectants. Water treatment facilities are dependent on them, especially chlorine, to kill harmful bacteria that is commonly present in public water systems.. Trihalomethanes, a class of chemicals that includes chloroform, are dangerous by-products of these treatment processes. Trihalomethanes have been linked to colon and rectal cancers, as well as birth defects, low birth weight and miscarriage.. Scientists suspect that trihalomethanes in drinking water may also be causing thousands of cases of bladder cancer every year. In a 2007 report, a startling 50% increase in bladder cancer risk was identified in a group of subjects who consumed water with trihalomethane concentrations higher than 21 parts per billion. The current EPA limit for total trihalomethanes in drinking water is 100 micrograms per liter, or 1 part per billion in ...

The disinfection of potable water has dramatically reduced the instances of Cholera and similar ailments within a population drawing upon that water source. There is however the possibility that Natural Organic Matter (NOM) can interact with the disinfection compounds to form Disinfection By-Products (DBP). One group of DBPs are Trihalomethanes (THMs) with several compounds of the group being suspected carcinogens. Within the UK the total concentration of all THMs within drinking water must not exceed 100µg/l ...

4229 Bladder cancer risk has been linked in several studies with exposure to disinfection byproducts (DBP), a complex mixture of halogenated compounds found in chlorinated drinking water. Two major chemical families of the mixture are trihalomethanes and haloacetic acids. Experimental evidence shows activation of brominated trihalomethanes (THM) by GSTT1 and detoxification of haloacetic acids by GSTZ1. We hypothesized that polymorphisms in these genes may modify the risk posed by DBP, and investigated this in a large case-control study in Spain where elevated risk associated with DBP has been reported.. Methods: We created individual exposure profiles to DBP by combining information from residential histories from a personal interview with separately gathered historical water utility data. DBP exposure was estimated by the average household trihalomethane (THM) level from age 15 to interview. We investigated the joint effects on bladder cancer risk of THM exposure and polymorphisms in GSTT1 and ...

The influence of disinfection by-products (DBPs) on the operation and design of water treatment plants has been increasing since the early studies by Rook on trihalomethanes (THMs) (Stevens, 1977). Work conducted in the 1980s identified the existence of nonvolatile halogenated organics (non-THM organics), of which the majority produced by chlorination were haloacetic acids (HAAs), within the HAAs, dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) were the dominant members. Concern over potential health effect led the U.S. Environmental Protection Agency (USEPA) to set a maximum contaminant level (MCL) for total THMs and HAAs. The disinfectant/disinfection by-product rule (D-DBP Rule) currently proposed by the USEPA will lower the MCL for THMs and HAAs. Past and pending DBP regulations have provided a momentum to seek a better understanding of how these compounds are formed as well as how their production can be controlled. Drinking water utilities are preparing for these major

Increased disinfectant use commonly takes place in hospitals and other health care settings. A cross-sectional study among active nurses in two Cypriot public hospitals (n = 179) was conducted to examine the prevalence of exposure to disinfection byproducts (DBPs), such as trihalomethanes (THMs) using both self-reported information and biomarker measurements. The objectives of this study were to: i) quantify the magnitude and variability of occupational exposure to disinfectants/DBPs in nurses, ii) generate job exposure matrices (JEM) and job task exposure matrices (JTEM) for disinfectants, and iii) assess the major determinants of urinary THMs in nurses. End of shift urinary total THM values showed high variability among the nurses, but did not differ between hospitals. The disinfectant group of alcohols/phenols was used by , 98% of nurses, followed by octenidine (82%), iodine and chlorine (39%, each), chlorhexidine (25%), formaldehyde (12%), hydrogen peroxide (11%), and peracetic ...

The water district is currently upgrading all three of its drinking water treatment plants in order to allow for new and improved methods of treatment that will further reduce the levels of THMs in treated water that we provide to the county. This will be accomplished by further delaying chlorination and enhancing coagulation, and eventually by switching to ozonation as the primary disinfection method instead of chlorination. This $150 million capital improvement project is scheduled to be completed in 2005. The district is examining ways that the project could be accelerated. Another important factor in reducing the amount of THMs in the treated water we provide is the need to improve the quality of the source water. Water imported from the Sacramento-San Joaquin Delta currently experiences salt water contamination and has high levels of organic compounds from agricultural drainage. These salts and organic compounds form THMs during the treatment process. The delta serves as the primary source ...

Disinfection By-Products and Human Health is based on contributions from speakers who participated in May 2011 workshops on Disinfection By-Products (DBPs) and Human Health at Ozwater 11 in Adelaide, Australia or at an AWA sponsored workshop at the Curtin Water Quality Research Centre, Perth, Australia. The contributions are prepared to facilitate communication with practitioners, rather than researchers, making use of overview illustrations rather than dense text or data tables. Each chapter concludes with up to 5 key findings that are take-home messages for practitioners. Disinfection By-Products and Human Health is aimed specifically at drinking water professionals (engineers, chemists and public health professionals) working on the front lines of drinking water issues where they must encounter actual day-to-day issues of risk management concerning DBPs in relation to all the other regulatory and water quality issues they must manage. Although a topic this complex is certainly not amenable to ...

The objective of this study was to examine the potential of the magnetic ion exchange (MIEX®) process to remove nitrogenous disinfection byproduct (N-DBP) precursors while minimizing carbonaceous DBP (C-DBP) precursors in different water matrices. In the first phase of the study, the MIEX® process was tested in raw dinking waters and waters impacted effluent from wastewater treatment plant. Samples were collected from several drinking water/wastewater treatment plants in South Carolina. The effluent impacted source waters were prepared by mixing treated wastewater effluents with a drinking water. For all samples, formation potential (FP) tests were conducted for regulated trihalomethanes (THMs), haloacetic acids (HAAs), and selected N-DBPs such as nitrosamines and halonitromethanes (HNMs) under favorable conditions of formation, before and after MIEX® treatment. The removal efficiencies were compared for UV absorbance, dissolved organic carbon (DOC), and DBP FP. The MIEX® process

The aim of the work reported in this article was to investigate the effects of medium temperature and industrial by-products on the key hardened properties of high performance concrete. Four concrete mixes were prepared based on a water-to-binder ratio of 0.35. Two industrial by-products, silica fume and Class F fly ash, were used separately and together with normal portland cement to produce three concrete mixes in addition to the control mix. The properties of both fresh and hardened concretes were examined in the laboratory. The freshly mixed concrete mixes were tested for slump, slump flow, and V-funnel flow. The hardened concretes were tested for compressive strength and dynamic modulus of elasticity after exposing to 20, 35 and 50 °C. In addition, the initial surface absorption and the rate of moisture movement into the concretes were determined at 20 °C. The performance of the concretes in the fresh state was excellent due to their superior deformability and good segregation resistance. In

Sampling for DBPs. Any Non-Transient Non-Community (NTNC) or Community public drinking water system that routinely and regularly applies a chemical disinfectant is required to monitor for DBPs and to submit a DBP Sampling Plan to be approved by the Division. Testing for two groups of DBPs is required, total trihalomethanes (TTHM) and five haloacetic acids (HAA5). Sampling for DBPs may be required quarterly, annually, or every three years depending on the water source, population size, and prior DBP results. A water system can check its monitoring schedule . Water systems that have started chlorinating or changed their water source should contact the Division for guidance and an updated schedule.. DBP Sampling Form. TTHM sample sites should be located where previous sampling results were highest. TTHM tend to increase with time after chlorination, so where data is limited, sample sites can be located at distribution system endpoints far from the treatment plant (but not dead ends without use) or ...

The optical properties of DOM were more dependent on the BC types with different origins (sludge, corn, and rice) rather than on the extraction time. A large amount of DOM was released during the initial period of the extraction (1 day), which was equivalent to ...

It has been established that chlorination of naturally coloured waters produces chloroform and other trihalomethanes in concentrations that are considerably higher than most of the organic microcontaminants commonly found in polluted surface waters.. The objective of this study was to investigate the origin of the trihalomethanes in drinking water and the mechanism responsible for their formation. Chapter 1 gives a historical survey of the use of chlorine in drinking water treatment. The main application of chlorine originally was disinfection. Soon after, chlorination became common practice for the oxidative removal of earthy tastes and odors. Additionally the bleaching of naturally coloured water was found to be advantageous.. As a result of studies of the various reactions between chlorine and inorganic ammonium the breakpoint phenomenon was discovered in 1940. Since then breakpoint chlorination is used for quantitative removal of ammonium from raw water. Until that time alternate methods of ...

In April 2013, the city of Flint, Michigan switched its water supply from Detroits Department of Water and Sewerage -which drew from Lake Huron-to a local treatment plant that took water from the Flint River. The switch was made as a cost-saving measure for the struggling city. Almost immediately, residents began to complain about the waters color, taste and odor. As it turned out, these would be the least of their worries.. Because water from the Flint River had high levels of bacteria, it was treated with additional chlorine. Chlorine reacts with organic material in the water to produce carcinogenic byproducts such as trihalomethanes; it also makes water more acidic, which corrodes pipes. Federal law mandates adding anti-corrosive agents to drinking water in large cities; but officials in Flint did not bother to follow the law.. After the city began drawing from the Flint River, its drinking water spiked in bacteria and trihalomethanes. Legionnaires disease appeared and caused at least 10 ...

Hi, I am currently going down the rabbit hole of brewing tea and I just wanted to add some expertise to this post, as I have 11 years background in the water purification industry here in Canada.. Water is obviously the main ingredient for every beverage known to man, even freshly squeezed juice is mostly water. What is very important to know, is that chlorinated tap water reacts with the organic matter in tea (and any other organic material) to create organochlorines. This is a chlorination byproduct with very little research done because it is not directly added to tap water - it is a result of unforseen reactions after chlorination.. These byproducts can include chloroform, carbon tetrachloride, trihalomethanes, and haloacetic acids. While little is known about them, what IS known is that they are all carcinogenic and have the ability to cause free radicals and/or buildup in our fat tissue.. In my opinion, you should start with pure water - Reverse Osmosis or Distilled are the only two ...

A study by the California Department of Health published in March, 1998, tracked the drinking water consumption and the pregnancy outcomes of 5,144 pregnant women in a prepaid health plan during the period 1989-1991. The drinking water consumption of the women was ascertained as soon as their pregnancy was registered in the studys database. Later, the outcome of their pregnancy was compared with the amount of water they drank and the total amount of trihalomethanes (THMs) they received from water treated with chlorine (information received from the water companies).. ...

The paper describes how the researchers re-analysed data from a study called the Spanish Bladder Cancer case-control study, which was carried out during 1998 - 2001. As part of this study, 1,271 people without bladder cancer were interviewed about a variety of their habits and behaviours - this was to compare them to people with bladder cancer as a control group.. The new study looked at the information recorded about these control subjects, in particular whether they had said they drank tap or bottled water, how often they said they showered or took baths, and how often they remembered going to the swimming pool. It also looked at the information on their social background and where they lived.. Next, the researchers asked water companies around Spain for data from the same period, about the levels of certain types of by-product from the disinfection process called trihalomethanes (THMs). They also measured levels of these chemicals themselves. This allowed them to make a rough estimate of ...

Investigations of the relation between disinfection by-products and reproductive outcomes have thus far focused on exposure to trihalomethanes. Haloacetic acids are common by-products of water disinfection and can occur in concentrations as high as THMs. We investigated the association between exposure in pregnancy to HAA compounds in drinking water and risk for a stillbirth and assessed the relation of HAA exposure after controlling for THM exposure. In the analysis of exposure to each HAA by-product without adjustment for THMs, a relative risk greater than 2 was observed for intermediate exposure categories for total HAA and DCAA measures. However, after adjustment for total THM exposure none of the HAA measures examined was associated with stillbirth risk.. Collinearity in the occurrence of different classes of disinfection by-products in household water supplies makes it difficult to determine the independent effects of specific by-products. Water use behaviours contribute different amounts ...

Nine local dominant freshwater algal species, including green algae (Chlorella sp., Chlamydomonas sp. and Scenedesmus quadricauda), diatom (Navicula pelliculosa, Nitzschia palea Grunow and Synedra sp.), blue-green algae (Microcystis sp., Chroococcus sp. and Gloeocapsa sp.) were isolated from source water reservoirs and cultivated in the laboratory. The algal biomass was chlorinated (20 °C, pH 7, residual chlorine 2 mg L-1). Yields of chloroform, dichloroacetic acid, trichloroacetic acid, dichloroacetonitrile and trichloroacetonitrile and genotoxicity of the chlorinated solutions at eight chlorination intervals (0.5, 1, 2, 5,10, 30, 60 and 120 min) were determined via SOS-ChromoTest and Comet assay. The results showed that green algae and diatom were more effective disinfection by-products (DBPs) precursors than blue-green algae. Genotoxicity was shown to be chlorination time-dependent, in agreement with our previous findings, suggesting that intermediate DBPs rather than trihalomethanes or haloacetic

Ill go ahead and answer that for you - its a definite no. At least according to this study, which looked at what grows in the biofilms (goop) that form along dishwasher door seals. First of all, its kind of amazing that anything can survive the crazy environmental fluctuations of a dishwasher: from heat to salts and detergents, dishwashers are designed to destroy organic matter. But life finds a way, and apparently in biofilms, which in this case included large numbers of bacterial and fungal species, many of which can be pathogens. Yum!

Whenever I forget to use this stretchy net, I find my bowls- which Id carefully positioned facing inward and down on the top rack- facing up and full of water. Its a small inconvenience, but an inconvenience nonetheless. And if youre using a less effective dishwasher, sometimes that water contains sediment from the other dishes. Gross! My husbands job moves us around a lot right now, so were longtime renters and have to just deal with crappy appliances. Dumping out water every time I emptied the dishwasher was really getting on my nerves. The Boon Span Net helps me get along a little better with my current dishwasher. Now, Monkeys bowls dont get flipped over, and they get washed ...

This is a completely non-medical post that will be of no interest to 99% of the regular readers of this blog (maybe a little interest if you want to see how I fixed my dishwasher), but I wanted to put it up for the search engines to help anyone try to fix had the same problem that ate up a few hours of my day.. When our previous dishwasher died on us last year, we spent a little more money on a Bosch dishwasher. So far, havent had too many complaints about it. On the pro side, it is quiet and it gets the dishes quite clean. There also isnt a water jet spinning around above the top rack, so you can fit larger items up there. On the con side, there isnt as much space for plates on the bottom. We have trouble fitting a days worth of dishes from our 6 person family inside. And theres no way youll get a large pan in there unless you take up the whole upper rack. So I wouldnt recommend a Bosch dishwasher for a larger family ...

In countries located in tropical zones, a critical task in drinking water plants is the removal of the natural organic matter (NOM), particularly during the rainy season when a lot of organic matter is transported by run-off into the water bodies. It provokes overloaded in the plants and they have often needed to be shut down. In the dry season, the NOM removal is also difficult due to its low concentration, and greater coagulant dosages are needed to destabilize the negative charge of the NOM.. In order to increase the NOM removal, synthetic polymers based on acrylamide are sometimes used as coagulant aids. However, they have been associated with Alzheimerand are carcinogenic. Therefore, the present requirement is to find new treatments affordable for the conditions existing in tropical countries. The application of green compounds has become a responsibility to guarantee the health of the population.. The situation in Nicaragua is similar to that in many tropical countries. At present, there ...

In a case-control study a statistically significant association was recorded between the introduction of infants to heated indoor swimming pools and the development of adolescent idiopathic scoliosis (AIS). In this paper, a neurogenic hypothesis is formulated to explain how toxins produced by chlorine in such pools may act deleteriously on the infants immature central nervous system, comprising brain and spinal cord, to produce the deformity of AIS. Through vulnerability of the developing central nervous system to circulating toxins, and because of delayed epigenetic effects, the trunk deformity of AIS does not become evident until adolescence. In mature healthy swimmers using such pools, the circulating neurotoxins detected are chloroform, bromodichloromethane, dibromochloromethane, and bromoform. Cyanogen chloride and dichloroacetonitrile have also been detected. In infants, the putative portals of entry to the blood could be dermal, oral, or respiratory; and entry of such circulating small molecules

The ion chromatography combined solid phase extraction (SPE) method was developed for the analysis of low concentration haloacetic acids (HAAs), a class of disinfection by-products formed from chlorination of hospital wastewater. The monitored HAAs included monochloroacetic acid, monobromoacetic acid, dichloroacetic acid, dibromoacetic acid and trichloroacetic acid. The method employed a sodium hydroxide eluent at a flow rate of 0.8 ml/min, electrolytically generated gradients, and suppressed conductivity detection. To analyze the HAAs in real hospital wastewater samples, C18 pretreatment cartridge was utilized to reduce samples turbidity. Preconcentration with SPE and matrix elimination with treatment cartridges were investigated and found to be able to obtain acceptable detection limits. Linearity, repeatability and detection limits of the above method were evaluated. The detection limits of monobromoacetic acid and dibromoacetic acid were 2.61 microg/L and 1.30 microg/L, respectively, and the other

Planet - powder. Seventh Generation- powder and liquid. Method- Smarty Dish Detergent tabs in pink grapefruit (20 count unwrapped in tub). Ecover-tabs (25 count individually wrapped in clear plastic). Let me start by saying, Im not a fan of powder dishwasher detergent and avoid it. My favorite are tabs because I know the right amount is being used and there is no mess. Liquid falls in the middle.. The Palmolive Eco+ ($2.99 at Fred Meyer/Krogers) is basically a greenwashed product. The only ecological benefit of these dishwasher detergent is that it is free of phosphates. IMO, it didnt clean nearly as well as I expected. This will not be used in our home in the future.. I didnt like the Planet ($4.59 at Fred Meyer/Krogers) powder AT ALL. My dishes came out with residue and most had to be rewashed. It was a trying few weeks. I will not use Planet again.. The Ecover ($3.99 at Whole Foods) tablets worked okay. The tablets had a tendency to crumble somewhat when taken out of their wrap. They ...

by Cris Carl, Networx. A walk down the dish product aisle in most anyone s local supermarket will turn up an almost surprising bevy of new cleaning products. The common denominator companies are reaching for in many products is low or no phosphates. Phosphates have been the primary cleaning agent in dishwasher and laundry soaps for a long time. As of July 1, 2010, 16 states have banned phosphate content in cleaning products to 0.5 percent. Up until now, companies could get away with content up to 8.7 percent. Low phosphate dishwasher detergent, while better for the environment, has proven to be lackluster in many cases in its ability to clean. Here is some overall information about low-phosphate cleaning products and how they work in dishwashers.. First of all, why are phosphates in dishwashing detergents being banned?. Phosphates are noted to cause an increase in algae bloom as well as other aquatic plant life. More algae equals less oxygen for other aquatic life, i.e. fish. In other words, ...

The nice thing about this is there is no need to mix up a big batch…so there are no clumping/hardening issues to deal with. All you need is a teaspoon to add the oxygen bleach to the dispenser and then you can add the Dawn directly from the squeeze bottle (just eyeball it).. Finally, find a small container that can sit upright in the top basket and fill it with 1/2 cup vinegar. I have been using vinegar as a rinse aid for a long time…but I usually just pour it into the bottom of the dishwasher when I start it up. By putting the vinegar in a bowl or cup, it will overfill as the cycles goes on, and the diluted vinegar will be evenly dispersed throughout the dishwasher.. I know that MANY people put vinegar in the rinse aid dispenser…but Ive tried that and it hasnt worked for me.. A word of caution: Dont use MORE than 1/2 teaspoon of the Dawn dish soap or you could have a sudsy overflow on your hands. That being said, if you peek in the dishwasher during the wash cycle…you WILL see a fair ...

Chemicals and other toxins are either added to, or remain in the water we drink whether it is from mains, rain or bore source supply.. In South Australia, we entrust water treatment facilities with the responsibility of providing safe drinking water, but they only test and regulate a stipulated number of contaminants. Some chemicals like chlorine and fluoride are deliberately added to the tap water for specific purposes including the disinfection process, which is used to rid the water of harmful micro-organisms.. Other contaminants that can be found are: lead; by-products called trihalomethanes (THMs) that form when the chlorine reacts with organic matter in the water; chromium and arsenic (which is naturally occurring in certain types of rocks and can potentially contaminate groundwater and underground reservoirs).. There are several other contamination risks that can also enter the waterways from industrial effluent directly emptied into the ground water systems or from contaminated ...
