How’s the Water Quality Today?

Water pollution happens when harmful substances, like chemicals or solid wastes (from humans or animals), are discharged into a body of water. The most common forms of water pollution include: agriculture (fertilizers, pesticides, and nutrients, bacteria from animal waste products); sewage and wastewater; oil pollution; and radioactive substances.

Marin County Ocean & Bay Water Quality Testing Program

MARIN COUNTY OCEAN & BAY WATER QUALITY TESTING Once a week from April 1 through October 31, Marin County Environmental Health Services (EHS) monitors 27 ocean, bay and freshwater sites to determine if a beach meets the California water quality standards for recreational water contact. EHS works cooperatively with other agencies to collect water samples and post advisory signage as needed at the designated sampling sites.EAC participates in this program in partnership with Point Reyes National Seashore monitoring two sites: Drakes Estero and Drakes Beach. WEEKLY WATER QUALITY RESULTS (APR 1 - OCT 31)

Watershed Council

TOMALES BAY WATERSHED COUNCIL The Tomales Bay Watershed Council (TBWC) was formed in 1999 by the region’s stakeholders with an interest in improving the watershed’s vital natural resources. The TBWC includes representatives from local, state, and federal agencies, environmental organizations, citizen and residential groups, agricultural and shellfish industries, recreational interests, and individual residents. The EAC is an active member of the council.COASTAL MARIN WATERSHED MAP

HARMFUL ALGAL BLOOMS
STATE OF CALIFORNIA MAP & WEBSITE

Harmful Algal Blooms (HABs) can pose a health risk to people and animals, harm aquatic ecosystems, and limit the use of drinking and recreational waterbodies due to the toxins, odors, and scums or mats they can produce. The State of California created a portal as an informational resource for the public and also functions as a tool to support coordination with statewide partners to address HABs. The content is developed by the California Cyanobacteria and HAB (CCHAB) Network and participating state agencies.

The content included here focuses on freshwater and estuarine HABs; similar content for marine (coastal) HABs is provided by the California Harmful Algal Bloom Monitoring and Alert Program (CalHABMAP) webpages.

How’s the Air Quality Today?

Air pollution happens when certain gases or particulates are released into the air and cause harm to people, animals, and/or plants. Some of the types of air pollution include smog and soot; hazardous air pollution from industries that release chemicals like benzene and metals like lead and mercury; exhaust from cars and wildfire smoke releases polycyclic aromatic hydrocarbons (PAHs); greenhouse gases like carbon dioxide, methane, and hydrofluorocarbons (HFCs); wildfire smoke, and pollens and molds. Air pollution also includes greenhouse gases (GHG), like carbon dioxide. GHG cause the climate to warm by trapping heat from the sun in the earth’s atmosphere. Ozone in the troposphere is a GHG and also a health hazard.

SPARE THE AIR Spare the Air was created in 1991 by the Bay Area Air Quality Management District to alert residents when air quality is forecast to be unhealthy and to share information on ways to reduce air pollution. From easy, everyday tools—such as commute tips—and air quality resources, such as explanations of major air pollutant sources and their health effects, Spare the Air focuses on educating and helping residents choose actions that will improve air quality and make the Bay Area a healthier, more enjoyable place to live. While ozone is produced every day, cooler temperatures and steady winds normally keep it from building up to unhealthy concentrations. During the Bay Area’s warmer months between April and October, the longer, hotter days mean that ozone can accumulate to levels that violate federal health-based standards. When this is expected to happen, a Spare the Air Alert is called. Learn more about ozone effects on health.

The recently redesigned site highlights air quality in your local area first, while still providing air quality information at state, national, and world views. A new interactive map even lets you zoom out to get the big picture or drill down to see data for a single air quality monitor. AirNow reports air quality using the official U.S. Air Quality Index (AQI), a color-coded index designed to communicate whether air quality is healthy or unhealthy for you. When you know the AQI in your area, you can take steps to protect your health.
