Monochloroacetic acid in Nevada
Monochloroacetic acid is a disinfection byproduct regulated by EPA as one of five haloacetic acids that are formed when chlorine, chloramines or other disinfectants react with organic and inorganic matter in water. [read more]
The Most Polluted Communities in Nevada
3 water utilities reported detecting Monochloroacetic acid in tap water since 2004, according to EWG's analysis of water quality data supplied by state water agencies
Ranked by highest average Monochloroacetic acid level
| Rank | System | Population Served | Positive test results of total reported tests | Average Level (Range) |
|---|---|---|---|---|
| 1 | City of Henderson Boulder City, NV | 246,000 | 3 of 5 | 1.14 ppb (0 to 3.2 ppb) |
| 2 | Dayton Valley Water System Dayton, NV | 12,035 | 1 of 1 | 0.57 ppb (0.57 ppb) |
| 3 | Fernley Public Works Fernley, NV | 14,000 | 1 of 2 | 0.36 ppb (0 to 0.73 ppb) |
Health Based Limits for Monochloroacetic acid
| Standard | Description | Level |
|---|---|---|
| Maximum Contaminant Limit (MCL) | The enforceable standard which defines the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to health-based limits (Maximum Contaminant Level Goals, or MCLGs) as feasible using the best available analytical and treatment technologies and taking cost into consideration. Source: U.S. Environmental Protection Agency. | 60 ppb |
| Maximum Contaminant Limit Goal (MCLG) | A non-enforceable health goal that is set at a level at which no known or anticipated adverse effect on the health of persons occurs and which allows an adequate margin of safety. Source: U.S. Environmental Protection Agency. | 70 ppb |
| Lifetime health-based limit, non-cancer risk | Concentration of a chemical in drinking water that is not expected to cause any adverse, noncarcinogenic health effects for a lifetime of exposure. The Lifetime health-based limit (or Health Advisory, HA) is based on exposure for a a 70-kg adult consuming 2 liters of water per day. Source: U.S. Environmental Protection Agency. | 70 ppb |
| Children's health-based limit for 1-day exposure | Concentration of a chemical in drinking water that is not expected to cause any adverse, noncarcinogenic health effects for up to one day of exposure. The One-Day health-based limit (or Health Advisory, HA) is typically set to protect a 10-kg child consuming 1 liter of water per day. Source: U.S. Environmental Protection Agency. | 200 ppb |
| Children's health-based limit for 10-day exposure | Concentration of a chemical in drinking water that is not expected to cause any adverse, noncarcinogenic effects for up to ten days of exposure. The Ten-Day health-based limit (or Health Advisory, HA) is typically set to protect a 10-kg child consuming 1 liter of water per day. Source: U.S. Environmental Protection Agency. | 200 ppb |
| Drinking Water Equivalent Level | A lifetime exposure concentration protective of adverse, noncarcinogenic health effects, that assumes all of the exposure to a contaminant is from drinking water. Source: U.S. Environmental Protection Agency. | 350 ppb |
