For water professionals, the project highlights the growing focus on PFAS removal, source-water protection and critical infrastructure improvements.<\/p>\n<p>The City of Dayton, Ohio, has selected engineering and consulting firm Tetra Tech to design advanced treatment solutions for what is planned to be the nation\u2019s largest dedicated facility for removing per- and polyfluoroalkyl substances, commonly known as PFAS, from drinking water.<\/p>\n<p>The facility has a projected construction cost of $350 million. Under an eight-year contract, Tetra Tech\u2019s engineers, scientists and technical specialists will build upon the company\u2019s previous planning work for the city and develop solutions addressing legacy PFAS contamination in the Mad River Well Field.<\/p>\n<p>The well field supplies Dayton\u2019s 70-year-old Ottawa Water Treatment Plant, which produces approximately 96 million gallons of drinking water per day. The regional water system serves more than 430,000 people.<\/p>\n<p>Tetra Tech will collaborate with Dayton Department of Water engineers, operators, technical staff and other stakeholders. According to the company, the project\u2019s designs will be intended to meet PFAS regulations, modernize aging infrastructure and minimize long-term operating costs.<\/p>\n<p>The project reflects the increasing importance of monitoring and protecting source water as utilities respond to PFAS contamination and evolving drinking-water requirements. Its scale could also offer valuable lessons for other water systems evaluating treatment technologies, infrastructure investments and the long-term operational demands associated with PFAS removal.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row admin_label=&#8221;CTA &#8211; PIONEER&#8221; _builder_version=&#8221;4.6.1&#8243; _module_preset=&#8221;default&#8221; background_color=&#8221;#d2e2f4&#8243; width=&#8221;100%&#8221; width_tablet=&#8221;100%&#8221; width_phone=&#8221;80%&#8221; width_last_edited=&#8221;on|desktop&#8221; border_radii=&#8221;on|12px|12px|12px|12px&#8221; global_module=&#8221;3747&#8243; saved_tabs=&#8221;all&#8221; collapsed=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text admin_label=&#8221;HDR&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; header_2_font=&#8221;Open Sans|700||on|||||&#8221; header_2_text_align=&#8221;center&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h2>PIONEER REMOVES LEAD, CYST &amp; PFOA\/PFOS<\/h2>\n<p>[\/et_pb_text][et_pb_blurb content_max_width=&#8221;600px&#8221; admin_label=&#8221;CALL-TO-ACTION&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; custom_padding=&#8221;|10px||10px|false|false&#8221; custom_padding_tablet=&#8221;&#8221; custom_padding_phone=&#8221;|20px||20px|false|false&#8221; custom_padding_last_edited=&#8221;on|phone&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p><strong>PIONEER<\/strong> is the First of its Kind Whole-House Lead, Cyst &amp; PFOA\/PFOS Filtration Solution! <a href=\"https:\/\/www.enpress.com\/site\/contact-us\/\">Contact us<\/a> to learn more about this revolutionary product.<\/p>\n<p>[\/et_pb_blurb][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dayton has selected Tetra Tech to design what is expected to become the largest dedicated PFAS water treatment facility in the United States.

In their recent study, they found that many prolonged droughts can cause a higher risk of exposure to arsenic in well water. Maine, New England, the Midwest, and the Southwest are all areas whose arsenic levels are regularly higher than the federal level allows. Although municipal water supplies are carefully monitored, private well water is not. This can be a danger to Americans because over 43 million people rely on private well water. A previous study revealed that somewhere between 1.5 and 2.9 million people are drinking water with unsafe levels of arsenic, and this number may increase to over 4 million in case of a drought.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">Increased levels of arsenic may be caused by a decrease in groundwater levels, which causes changes in water chemistry. There are also some human responses to droughts, such as using ground water rather than surface water, which may also affect exposure. The number of droughts is expected to increase as a result of climate change, exposing even more Americans to unsafe drinking water.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">Arsenic is highly dangerous because it causes a wide variety of health issues, and is odorless, colorless and tasteless - making it undetectable without a test. To help combat this issue, many states which are at high risk for droughts have programs to provide private well owners with arsenic tests. Although not all testing is free, these programs help make it affordable since it is recommended to test water every 3-5 years. By increasing awareness, doing additional research, and regularly testing water we can fight this issue.\u00a0<\/span><\/p>","_et_gb_content_width":"","_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[1],"tags":[57,51],"class_list":["post-6625","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-enpress-news","tag-drinking-water","tag-water-system"],"yoast_head":"<!--
