The state of Ohio is collecting water samples from homes and public water systems to determine arsenic levels throughout the region
The state of Ohio is determining regions with elevated arsenic levels in groundwater by collecting water samples from homes and public water systems. State health officials are using workshops to educate the public about the dangers of ingesting arsenic and offering tests for arsenic contamination in well water. The U.S. Environmental Protection Agency (EPA) regulates public water systems, but it does not have the authority to regulate private drinking water wells.
Whether you are a sales, installation or service professional, water testing is vital to completing your job. Providing consultation, offering recommendations and addressing problems can only be done after a proper water analysis has been completed.

When considering reverse osmosis (RO) for water treatment, there are several things that should be taken into account. One of the most important things to consider is the quality of the water to be treated. RO is widely used to remove harmful inorganic contaminants; however, due to the limitations and higher operating cost, pretreatment of the water may be necessary. For example, hardness minerals are common in groundwater, and at high levels, pretreating with a softener is often recommended.
