268 systems monitored for Lead and Copper in FY2011. Two <strong>water</strong> systems exceeded the<br />
copper action level and two <strong>water</strong> systems exceeded the lead action level in FY2011. Water<br />
systems that exceed an action level must submit a corrosion control plan, conduct source <strong>water</strong><br />
and <strong>water</strong> quality parameter monitoring, and return to six month monitoring. In addition,<br />
systems that exceed the lead action level must also provide their customers with lead education<br />
materials. Approximately half of these <strong>water</strong> systems had provided the required proof that they<br />
notified their customers of the sample results by the end of FY2011. A complete <strong>report</strong> of lead<br />
and copper compliance data for calendar year 2011 will be included in the 2011 <strong>annual</strong><br />
violations <strong>report</strong> which will be produced in May or June 2012.<br />
Disinfection Byproduct Monitoring and Compliance<br />
367 community and NTNC <strong>water</strong> systems were required to monitor for disinfection byproducts.<br />
DBPs include total trihalomethanes (TTHM) and haloacetic acids (HAA5). Listed below are the<br />
systems that incurred MCL violations.<br />

DBP VIOLATIONS<br />
System Contaminant Source<br />
CWM Water Authority HAA5 Purchase Surface<br />
Guin Water and Sewer Board HAA5 Surface<br />
Ranburne Water and Sewer <strong>Department</strong> HAA5 Purchase Surface<br />
Swearingen Water System HAA5 Purchase Surface<br />
Wedowee Water, Sewer and Gas Board HAA5 Surface<br />
The <strong>Department</strong> has issued orders against three of the above systems. These three systems<br />
received more than one violation and were not able return to compliance, necessitating an order.<br />
These orders require the system to return to compliance within a specified amount of time. No<br />
<strong>water</strong> systems incurred monitoring violations for disinfection byproducts during FY2011.<br />
All systems with a surface source or a source that is classified as ground<strong>water</strong> under the<br />
influence of surface <strong>water</strong> (GWUDI) are required to monitor for total organic carbon (TOC).<br />
These systems were required to collect raw <strong>water</strong> and a combined filtered <strong>water</strong> sample each<br />
month. TOC results from each plant are evaluated to determine if the plant is meeting TOC<br />
removal requirements or to determine if monitoring could be reduced to quarterly for TOCs. No<br />
<strong>water</strong> systems incurred treatment technique violations for failure to meet TOC removal<br />
requirements.<br />
Laboratory Certification Program<br />
<strong>Department</strong> regulations require an <strong>annual</strong> fee for recertification of <strong>drinking</strong> <strong>water</strong> laboratories.<br />
The fee for certification varied from $170.00 for bacteriological certification to a maximum of<br />
$680.00 for chemical laboratory certification. All chemical and bacteriological analyses of <strong>water</strong><br />
samples required by the State must be analyzed at a laboratory certified by ADEM.<br />
