Why Monitor Water for Selenium with KETOS

Selenium is a rare trace element found in soil originating from sedimentary deposits. Selenium can enter the waterways naturally (via erosion and surface runoff) and through human activity (via industrial discharges from mining).

While small amounts of selenium are essential for human health, the EPA limits selenium in drinking water to 0.05 mg/L as higher amounts can be toxic.

This challenge with selenium is that the difference between “essential” and “toxic” is quite slim, and even relatively small amounts of selenium (if released into the environment) can adversely affect wildlife. Due to a general concern for how selenium can affect an entire ecosystem, the EPA adjusted its selenium regulations in 2016 to include selenium contamination in food webs (not just water). There is also potential for rules surrounding selenium to become even more severe in the coming years.

While industrial and manufacturing organizations must already treat wastewater for selenium before discharge, water operators must continuously comply with regulations while staying vigilant should a change in compliance occur. Having a water quality management solution that can monitor for selenium and set threshold-based alerts can ensure organizations maintain compliance while protecting the surrounding environment from contamination.

What are the Issues with Selenium in Water?

Selenium, a naturally occurring element, is essential in trace amounts for various biological functions, but elevated levels in water can pose significant challenges and concerns. Here are key issues associated with selenium in water:

  • Health Risks: High concentrations of selenium in drinking water can pose health risks to humans and wildlife. Chronic exposure to elevated selenium levels may lead to selenosis, a condition characterized by hair and nail loss, gastrointestinal issues, neurological symptoms, and potential reproductive and developmental effects. Additionally, selenium bioaccumulation in aquatic organisms can result in selenium toxicity in wildlife, affecting populations and ecosystem health.
  • Environmental Impact: Selenium pollution in water bodies can have detrimental effects on aquatic ecosystems and biodiversity. Elevated selenium levels can bioaccumulate in aquatic organisms, leading to reproductive impairment, developmental abnormalities, and population declines in sensitive species such as fish, birds, and amphibians. Selenium contamination can also impact food webs and ecosystem functioning, contributing to ecological imbalances and habitat degradation.
  • Mining and Industrial Activities: Selenium contamination in water often stems from anthropogenic sources, including mining operations, coal combustion, agricultural runoff, and industrial discharges. Mining activities can release selenium from ore deposits, while coal combustion can emit selenium-containing ash and particulate matter into the atmosphere, which can then deposit into surface water bodies. Contaminated runoff from agricultural lands treated with selenium-containing fertilizers can also contribute to selenium pollution in waterways.
  • Regulatory Concerns: Governments and regulatory agencies establish guidelines and standards for selenium levels in drinking water and aquatic ecosystems to protect human health and the environment. Compliance with these regulations presents challenges for industries and municipalities, necessitating effective monitoring, treatment, and management measures to mitigate selenium pollution and ensure water quality.
  • Eutrophication: Selenium can contribute to eutrophication in water bodies when present in elevated concentrations. Selenium enrichment can stimulate algal growth and bloom formation, leading to oxygen depletion, fish kills, and habitat degradation. Managing selenium inputs and controlling nutrient pollution are essential strategies for preventing eutrophication and preserving water quality and ecosystem health.
  • Treatment Challenges: Removing selenium from water sources can be challenging due to its chemical properties and solubility. Conventional water treatment methods such as coagulation, sedimentation, and filtration may be ineffective for selenium removal. Advanced treatment technologies such as ion exchange, adsorption, and membrane filtration may be required to reduce selenium concentrations to acceptable levels.
