We hope everyone finds the information contained helpful and reassuring that The Charter Township of Waterford is meeting and exceeding all Environmental Protection Agency (EPA) and Michigan Department of Environment, Great Lakes and Energy (EGLE) water quality requirements.
As part of the finalized requirements for the 1996 Amendments to the Safe Drinking Water Act, the following Consumer Confidence Reports (CCR) are submitted by The Charter Township of Waterford Department of Public Works (DPW).
Consumer Confidence Reports
In August 1998, Congress finalized language on the new Consumer Confidence Report (CCR) requirement as part of the 1996 Amendments to the Safe Drinking Water Act which will provide consumers more information on their drinking water and opportunities to get involved in protecting their source of water. It became effective in September of 1998.
As a result, the DPW has to deliver an annual CCR report to our customers by July 1 each year. For those requiring more information, the CCR final rule can be found on the EPA’s website.
As part of meeting state and EPA guidelines for contaminants within potable drinking water, the DPW analyzes all required Maximum Contaminant Level constituents on defined schedules established by EGLE. The schedule describes the number of samples required, their frequency, an approximate due date, the test code and the sampling container to be used as well as chemical, bacteriological, radiological, and lead/copper sampling.
Once taken and analyzed, the results are sent to the EGLE as part of the required reporting procedure. Any violations must be outlined along with an explanation as to retesting and/or remediation procedures.
Arsenic Levels in Waterford Township
Additionally, we like to provide our customers with analysis results for Arsenic concentrations in our public water supply. These results are from samples taken between November and December of 2001. Current regulations call for our water supply not to exceed 10 Parts Per Billion (PPB) of Arsenic at each of our 11 treatment plant sites. We are very pleased to report that the recent results show that finished water (water you receive at your tap) Arsenic levels at each of the 11 treatment plants are below 5 PPB. In addition, the raw water (untreated) levels of Arsenic at each of the 13 wellhead locations average only 2.78 PPB.
Per- and Polyfluoroalkyl Substances (PFAS)
Per- and polyfluoroalkyl substances, sometimes called PFCs, are a group of chemicals that are resistant to heat, water, and oil. PFAS have been classified by the EPA as an emerging contaminant on the national landscape. Although the understanding of these emerging contaminants is constantly evolving, elevated levels of PFAS have the potential to cause increased cholesterol, changes in the body’s hormones and immune system, decreased fertility, and increased risk of certain cancers. Links to these health effects in humans are supported by epidemiologic studies and by laboratory studies in animal models.
The EPA has not established enforceable drinking water standards for these chemicals. However, the EPA has set a lifetime health advisory (LHA) level in drinking water for two PFAS compounds: perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). The PFOA and PFOS LHA is the level, or amount, below which no harm is expect from these chemicals. The LHA level is 70 parts per trillion (ppt) for PFOA and 70 ppt for PFOS. If both PFOA and PFOS are present, the LHA is 70 ppt for the combined concentration.
