Of all the Earth’s water, 97% is salt water found in oceans and seas.
The Massachusetts Department of Environmental Protection (DEP) certifies laboratories to analyze drinking (potable) and non-drinking (non-potable) water for certain contaminants.
You should verify that a laboratory's certification for lead analysis of drinking water is current when making your water sampling arrangements with a prospective laboratory. Costs range from $15.00 to $80.00. Also, you need to be aware that some laboratories may sell water treatment products and services or may be affiliated with other companies that offer such services.
Visit the MWRA to obtain a list of laboratories certified by DEP to analyze drinking water for lead.
The Massachusetts Department of Public Health (DPH) in Jamaica Plain will waive the cost of performing lead analysis of drinking water for any household in which it has been determined that a child's blood level is 20 micrograms per deciliter or greater.
