Methylene Chloride
Parameter Type: Drinking Water Testing for Volatiles
Parameter Name: Methylene Chloride
What it is and Where it Comes From:
Methylene chloride, also called dichloromethane, is a volatile, colorless liquid with a chloroform-like odor. Methylene chloride is used in various industrial processes, in many different industries including paint stripping, pharmaceutical manufacturing, paint remover manufacturing, and metal cleaning and degreasing. The most common means of exposure to methylene chloride is inhalation and skin exposure. OSHA considers methylene chloride to be a potential occupational carcinogen. Methylene chloride does not appear to occur naturally in the environment. It is made from methane gas or wood alcohol. Most of the methylene chloride released to the environment results from its use as a product by various industries and the use of aerosol products and paint removers in the home. Drinking water testing gives you several benefits like peace of mind, identifying contaminants in your water, and insight into health concerns. Safe Home offers Laboratory drinking water testing kits for Methylene chloride, allowing you to collect your water sample and ship it directly to our EPA-Certified Laboratory. This platform of drinking water testing for Methylene chloride will give you an accurate level based on the lowest level of a parameter our instruments can detect (Method Detection Level). Safe Home drinking water testing for volatiles can be used for city and well water supplies. Drinking water testing should be done any time you notice a significant change in your water quality.
Health Effects:
Methylene chloride can harm the eyes, skin, liver, and heart. Exposure can cause drowsiness, dizziness, numbness and tingling limbs, and nausea. It may cause cancer. Severe exposure can cause loss of consciousness and death. Workers may be harmed from exposure to methylene chloride. The level of exposure depends upon the dose, duration, and work being done. Acute toxic effects, including death, can result from ingestion. Methylene chloride is metabolized in the liver, in part to carbon monoxide, which will produce elevated carboxyhemoglobin levels and decrease the oxygen-carrying capacity of the blood. Carboxyhemoglobin levels may continue to rise for several hours after exposure has ceased. The fetus is particularly vulnerable to poisoning with carbon monoxide. Liver dysfunction may result from acute, high-level exposure to methylene chloride.
Solutions to Contaminant Levels:
What are the next steps after drinking water testing? A filter with granular activated carbon (GAC) is a proven option to remove certain chemicals, particularly organic chemicals, from water. GAC filters also can be used to remove chemicals that give objectionable odors or tastes to water such as hydrogen sulfide (rotten eggs odor) or chlorine. Reverse osmosis is a process that removes foreign contaminants, solid substances, large molecules, and minerals from water by using pressure to push it through specialized membranes. Here’s how reverse osmosis works. Unlike osmosis, which is a passive process, reverse osmosis requires external force (pressure) to work. Pressure is applied to a highly concentrated solute solution, such as salt water, to pass through a membrane to a lower concentrate solution. The membrane allows water to flow through but blocks out larger molecules, like contaminants. The reverse osmosis process leaves higher concentrations of solute on one side and only the solvent, or freshwater, on the other. Who do I need to contact to find out more information about water quality in my area? Every community water supplier must provide an annual report to its customers, known as a Consumer Confidence Report (CCR). The report provides information on your local drinking water quality, including the water’s source, contaminants found in the water, and how consumers can get involved in protecting drinking water. How often does the local public water system preform drinking water testing? Frequency of drinking water testing depends on the number of people served, the type of water source, and types of contaminants. Certain contaminants are tested more frequently than others, as established by the Safe Drinking Water Act. You can find out about levels of regulated contaminants in your treated water for the previous calendar year in your annual Consumer Confidence Report (CCR).

Drinking Water Testing - Parameter Types
Important Terms
-
MCL’s (Maximum Contaminant Levels) MCL’s are levels that set by the USEPA and are enforceable to Public Water Utilities, requiring additional treatment, when the levels are exceeded. These same guidelines should be at least considered, by owners of private wells. Some states have more strict guidelines than the USEPA. Not all parameters have MCL’s. If the parameter has an MCL, it’s listed.
-
MCLG’s (Maximum Contaminant Level Goals) MCLG’s are goals set by the USEPA that we should all strive for when consuming drinking water from any water supply. Concentrations of certain parameters (even below the MCL’s), are still not healthy for humans and animals to drink. These same guidelines should at least be be considered, by owners of private wells. Some states have more strict guidelines than the USEPA. Not all parameters have MCLG’s. If the parameter has an MCLG, it’s listed.
-
ACTION LEVELS ACTION LEVELS are a specified concentration of a respective parameter in drinking water, that is above a “treatment level” set by the USEPA. When these levels are exceeded, further treatment and monitoring is required by the respective utility who’s water violated this limit.Action Levels apply to parameter-rules such as but not limited to the Copper/Lead Rule.
-
PARTS PER MILLION (ppm) PPM is a scientific measurement which represents milligrams of the parameter being tested per liter of the respective liquid. Example: If Copper in your water supply is at a concentration of 1.00 mg/L, this is the same as saying the concentration is 1.00 ppm.
