上周, the College began to use the water wells on campus as the source of drinking water to the College community. 一年多来, the College has been drawing its water from the Town of Wellesley to allow us to make upgrades to our water system. We are now converting back to the College’s well water with the approval and oversight of the Massachusetts Department of Environmental Protection (MassDEP) Drinking Water Program and are following all applicable regulations and practices.
During the conversion, the community may notice some short-term differences. 例如, some people who are sensitive to the smell and taste of chlorine may notice chlorine residuals in the water as the system stabilizes, and because the Town of Wellesley’s water typically has lower levels of chlorine than the College’s system.
Prior to starting up our wells for distribution, extensive testing was completed to include the testing of 多氟烷基物质(PFAS). Test results came back non detectable for PFAS and all other items were within normal limits. 过去一年, the College installed a temporary treatment system designed to reduce PFAS in our water (though levels have never exceeded permissible limits), and work is underway to evaluate and design a permanent new treatment system.
The 设施管理 team will continue to work with expert consultants and
MassDEP to monitor our system and ensure high-quality drinking water is available to the College community.

12.17.2021: Important Update 皇冠体育 Testing of Water on Campus
A communication sent to the Wellesley College community shared that following a November 2021 routine test of the College’s water at 26 locations across campus, Wellesley received notification that t在这里 were exceedances of lead in three locations: The Distribution Center, 辛普森, 和McAfee Hall.
T在这里 are easy steps that individuals can take to reduce exposure to lead in water:
- Water bottle filling stations have been installed in major residential and academic buildings. 它们有过滤器，可以去除水中的铅. We suggest using the water bottle fillers for drinking water.
- 让 the water run from the tap for at least 30 seconds before using it for drinking or cooking any time the water in each faucet has gone unused for more than six hours. For the first use of the day, in the morning, run the water for 2-3 minutes.
- Flushing the tap means running the cold-water faucet for about 15-30 seconds. Although toilet flushing or showering flushes water through a portion of the plumbing system, you still need to flush the water in each faucet before using it for drinking or cooking.
- Note that boiling water does not reduce lead levels, so be sure to flush with cold water only.
- Do not cook with, drink, or prepare baby formula from the hot water tap. Hot water can dissolve lead more quickly than cold water. If you need hot water, draw cold water from the tap and then heat it.

更新8.6.2021:
2021年5月和7月, Wellesley College conducted its first tests for six per- and polyfluoroalkyl substances, 一种叫做PFAS6的物质, 在其校园饮用水井. 新的规则和测试 多氟烷基物质(PFAS) from the Massachusetts Department of Environmental Protection (MassDEP) were rolled out last fall and this is the first year municipal communities and all state public water suppliers are required to test water for these substances.
The MassDEP standard requires that the Maximum Contaminant Level (MCL) for the sum of PFAS6 may not exceed 20 nanograms per liter (ng/L), 也等于万亿分之20 (ppt). 从我们五月和七月采集的样品中, finished water from the College’s wells indicated results just at the MCL of 19.89年ppt.
我们分享这个 公众教育通告 我们的社区, which includes information on the PFAS levels found in College water, 对健康影响的解释, and steps community members can take to reduce exposure.
