Lead in Drinking Water How Flint has forever changed things  It has undermined public confidence  The impacts were unforgivable  That situation was unique  Water professionals have responded 

Where does lead come from? 

Lead is NOT found in sources of supply, following treatment, or in the distribution system



Water companies add chemicals to “protect” service lines and internal plumbing from leaching of lead



Lead likely comes from customers’ premises – service lines, solder or plumbing fixtures

How is lead testing done?  

 



Customer collects the sample First-flush, cold water Results vary from house to house Company notifies customers of their test results Required notification if exceed levels

How do we control lead? What is done to avoid what happened in Flint



Comply with the Regulation



Provide Corrosion Control



pH Monitoring and Control



Infrastructure Program - replace company’s lead service lines as identified



If sources change – we monitor, plan and react

Customer Outreach 

Focus on customer service ◦ Close collaboration between Call Center & Water Quality team ◦ Heightened awareness of water quality in general ◦ Customer-requested samples



Outreach to Schools, Town officials

School Sampling 

Used same protocol, sample size, standard as for residential testing



Tested in schools in 20 service towns



Selected fountains or food prep areas to be most representative of water that is consumed



Did ‘first draw’ and after fully flushed

Do Filters Reduce Lead in Water? NSF International certified water filters reduce the amount of lead in drinking water. 

Water dispensers or filters attached to the faucet allows the water to flow through adsorption media which captures contaminants such as lead.



Contaminants, such as lead, are trapped in the filter and remain inside the filter, reducing their presence in the finished drinking water.



Filters must be replaced according to the manufacturer's recommended filter capacity so they can continue to reduce lead and other contaminants for which they are certified. NSF certified filters reduce the contaminants as shown on the product's box or manual.



Many filters have meters or indicators that show when the filter needs to be replaced. Review the manufacturer’s specifications for details on filter change frequency and filter capacity.

Simple Steps You Can Take 

Run faucet for minute or 2 before drinking;



Use cold water for drinking or food preparation;



Look at plumbing and fixtures.

Pay particular attention if water has been stagnant for long period – vacations, summertime

To Recap….. 1.

Lead is NOT found in the company’s water supplies or distribution system

2.

The water delivered in system does not contain lead - treatment techniques in place, corrosion control program, and WQ sampling

3.

Source of lead is typically at the customers’ premise – service lines, solder, or fixtures

4.

Company is eager to give our customers additional information

5.

Customers can take steps at their property to reduce risks
