Safe, clean potable water is a basic necessity for a healthy life and community. It is vitally important to our daily life that we have a consistent supply of safe water to our homes, businesses and schools. In the US, the vast majority of households get their water from public water supplies, usually a city our county entity. As of 2015, over 85% of all households received public supply water. Producing clean, safe water is a challenging problem that can be compounded by changes in the source supply variations (surface water, ground water) and also seasonal variations such as runoff or drought conditions.
Public water supplies are regulated in the US by the EPA, and must meet stringent standards for contaminants and purity under the Safe Water Drinking Act (SWDA). Many states have established even more stringent regulations and guidelines and these standards are then enforced by each individual state. The standards specify acceptable levels of contaminants, testing frequency, and methods along with the procedures and methods allowed to treat public water supplies.
A reliable and efficient analytical support system is a critical component of the public water supply. Frequent, accurate analytical results ensure that the treatment protocols are functioning as specified, and that the water supply is safe to the public. Many analytical water labs also service rural customers with private wells to make sure that their water supplies are safe and within public guidelines. These laboratories often have dedicated water analyzers to provide rapid service to these customers.
Unity Scientific has several automated analytical solutions designed to accurately analyze drinking water samples for many contaminants, using EPA or Standard methods. These solutions have high throughput and can analyze many samples by operators with minimal training. These solutions come ready to use with approved methods and can help ensure that the the water supply is meeting or exceeding regulatory requirements while saving employee time, testing costs and disposal fees.
