Map Rec Cntr DC Lead Test (DRAFT)

DRAFT Map of 2016 DC Lead Testing Results (DC parks and Rec centers) DRAFT map is still in development
As mandated by the federal SafeDrinking Water Act, the DC Department of General Services (DGS) tests the water at DC Public Schools, DC parks and recreation facilities for lead. You can find their results on this webpage.

Purpose of Map:
In order to contribute to the Lead Free DC community-based advocacy, the Environmental Justice Committee of the DC Sierra Club, created the following map by georeferencing the data (pdf data charts) provided by DGS, to graphically depict the tested sites and the results by hovering over each dot for more information.  Note: please read map use authorization.  

Recreation and Parks Tested Data details:
At each facility, the Dept. of General Services (DGS) tested multiple places (different water fountains, etc.).
The map below shows the location of each facility as a dot each dot, and its test result is categorized by color according to the worst result at that facility.
For example: if most of the tested water fountains showed no lead, but one sink or water fountain tested positive, the entire park or recreation center appears as a red or yellow dot in the map. 
  • The dots are green if the worst lead reading at the park or recreation center was less than 1 part-per-billion (ppb). 
  • After preliminary 2016 DGS Lead Test results found that at least 12 DC Public Schools had high levels of Lead in their drinking water, the Mayor and DC Agencies raised the lead standard for the city to follow up and take action from 15ppb to 1 ppb. 
  • The current federal guideline mandated by the Environmental Protection Agency says 15 ppb is "too much lead."
  • Based on the new 2016 DC standard of 1ppb, above which the city is supposed to take action to reduce the lead levels. The map shows the dots are yellow if the maximum lead reading was between 1 and 15 ppb. They are colored red if the maximum reading was above 15 ppb. 
A quick note about lead tests:
Lead testing only reveals a snapshot in time. Lead levels can rise and fall over time, because sudden changes can cause more lead to enter the water. Examples of such changes include lead solder washing off the inside of a pipe, or changes in water chemistry. For this reason, green or yellow dots ("passing" tests by the federal standard) could still have lead-contaminated pipes--the tests jusm might have missed it. Also, the tests shown below don't tell us about the underlying source of lead for each recreation facility. As per the June 28th DC Council Public Hearing on Lead in Public Facilities city agencies in charge of protecting the residents from Lead in water haven't revealed exactly where the problem is.

Map Use and Authorization:
This map is a tool for community organizing only, it is solely to be used by community-based organizers to guide and inform DC public in general, impacted residents, parents and students. Authorization must be requested to use the georeferenced data and to share the map with other purposes in mind.
