2017 Parameter Data: Chloride - River, Brook and Tributary Sites

Road density, highway runoff, road salting practices, as well as the proximity of salt storage facilities can affect chloride concentration in inland lakes and ponds (those away from salt water). Chloride can be a general indicator of the degree of urbanization of a watershed, with typically higher levels of chloride found in more developed areas. Chloride is measured on a part per million basis (ppm). The average person can taste the “saltiness” of water around 250 ppm of chloride, which is well above the level found in any URI Watershed Watch freshwater site. Chloride is regularly analyzed only in May samples to capture winter road salt impacts and in October to assess seasonal variation. For a second year we did see a number of sites with higher chloride values in October than in May, a departure from usual that we can't yet explain. Watershed LOCATION MAY JUNE OCT.
