ERHWSC 07-08-2020 WHOLESALE CUST. FCL2 NOTICE

 

All Public Water Systems, like MHWSC, are required by the Safe Drinking Water Act to provide a Water Quality Report to its consumers on an annual basis to report the type and quantity of substances that are found in our water.  Each Service Area has its own report since the source of water is different for each system. The report is designed to inform you about the quality of the water we deliver to you 24 hours a day, 365 days a year. The report details where your water comes from, what it contains, and how that compares with regulatory standards. Our constant goal is to provide you with a safe and dependable supply of drinking water.  We are committed to ensuring the quality of your drinking water.  We want you  to have the information in the report so you will be able to understand and support the efforts needed to maintain the high standards required of our drinking water. The sources of drinking water (both tap and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals, and in some cases, can pick up substances resulting from the presence of animals or from human activity. Our water sources include ground water from multiple wells that pump from the Rio Grande Alluvial Aquifer and surface water from the Rio Grande River. The presence of contaminants in drinking water, including bottled water, does not necessarily indicates that it poses a health risk.  

In order to assure tap water is safe to drink, the Environmental Protection Agency (EPA) prescribes regulations which limit the amounts of certain contaminants in water provided by public water systems. The Food and Drug Administration (FDA) prescribes regulations which establish limits for contaminants in bottled water which must provide the same protection for public health. The data in this report was prepared from the most recent required tests set by the EPA. The Texas Commission on Environmental Quality conducts most of the water quality tests and provides the results for this report.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These persons should seek advise about drinking water from their health care providers. If you have any questions about these reports, contact the main office.
