Here\u2019s the simple breakdown so you can tell what you\u2019re looking at (and what it means for snorkeling).<\/p>\n<p><strong>Quick cheat sheet<\/strong><\/p>\n<ul>\n<li><strong>Brown Water Advisory (BWA):<\/strong> Issued when the ocean is brown, cloudy, or turbid from stormwater\/surface runoff\u2014often after heavy rain (and it can be issued even if the water isn\u2019t literally brown).<\/li>\n<li><strong>High Bacteria Count (Beach Action Value) Advisory:<\/strong> Issued when lab testing shows enterococci (an indicator of fecal contamination risk) is above the state\u2019s Beach Action Value (BAV) threshold (130 per 100 mL).<\/li>\n<li><strong>Sewage Spill Advisory:<\/strong> Issued after a confirmed sewage spill into state waters; these advisories generally remain until follow-up water sampling shows bacteria levels are back below the BAV for affected beaches.<\/li>\n<\/ul>\n<h4>1) Brown Water Advisory<\/h4>\n<p>A Brown Water Advisory is the DOH Clean Water Branch\u2019s way of saying: runoff is hitting the ocean, and that runoff can carry land-based pollution (soil\/silt plus a long list of contaminants that can come along for the ride). The water may be brown, gray, or even colorless\u2014but it\u2019s often cloudy\/turbid, which is the red flag.<\/p>\n<p><strong>Snorkeler takeaway:<\/strong> If you see murky water, brown plumes, or flow from streams\/storm drains\u2014treat it as a no-go and move to a different plan (or wait for conditions to clear).<\/p>\n<h4>2) High Bacteria Count Advisory (Beach Advisory)<\/h4>\n<p>This one is data-driven. The state monitors for enterococci, an EPA-recommended fecal indicator bacterium. When results are high, DOH uses a threshold called the Beach Action Value (BAV)\u2014130 enterococci per 100 mL\u2014to decide when a site has an elevated risk.<\/p>\n<p><strong>There\u2019s also an important nuance:<\/strong><\/p>\n<p>A High Bacteria Count Notification can appear first (meaning the initial sample exceeded the threshold and the beach is being resampled).<\/p>\n<p>A Beach Advisory is posted if follow-up sampling confirms the exceedance (or if follow-up sampling can\u2019t happen right away, like before a weekend\/holiday). Advisory signs may be posted at the beach, and the advisory remains in effect until levels drop below the threshold.<\/p>\n<p>Snorkeler takeaway: Don\u2019t assume \u201cit looks clear\u201d means it\u2019s safe\u2014this advisory is in place because the numbers came back high.<\/p>\n<h4>3) Sewage Spill Advisory<\/h4>\n<p>A Sewage Spill Advisory is issued when DOH receives a report of a confirmed sewage spill into state waters (for example, reported by a permitted wastewater facility or verified by DOH staff). It\u2019s a higher-alarm situation because it\u2019s tied to an identified sewage contamination event, and it\u2019s meant to warn the public to stay out of affected waters.<\/p>\n<p><strong>Snorkeler takeaway:<\/strong> Treat this as a hard \u201cno\u201d until DOH cancels the advisory. DOH notes coastal waters are often safer after tidal flushing, but also emphasizes waiting for official instructions\/updates.<\/p>\n<p><strong>Bottom line for Maui snorkeling<\/strong><\/p>\n<p>All three advisories are different \u201clabels,\u201d but the practical rule is the same: if an advisory is active\u2014or the water looks questionable\u2014skip snorkeling and check the official DOH advisories for current status and locations.<\/p>\n<p><strong>Use these official pages:<\/strong><\/p>\n<ul>\n<li><a href=\"https:\/\/eha-cloud.doh.hawaii.gov\/cwb\/#!\/landing\" target=\"_blank\" rel=\"noopener\">Hawai\u02bbi DOH Clean Water Branch Advisories (Landing Page)<\/a><\/li>\n<li><a href=\"https:\/\/eha-cloud.doh.hawaii.gov\/cwb\/#!\/viewer\" target=\"_blank\" rel=\"noopener\">Hawai\u02bbi DOH Advisories Map \/ Viewer<\/a><\/li>\n<li><a href=\"https:\/\/health.hawaii.gov\/cwb\/beach-monitoring-program\/\" target=\"_blank\" rel=\"noopener\">DOH Beach Monitoring Program (What Advisories Mean)<\/a><\/li>\n<\/ul>\n<h3>Check Beach Conditions And Talk To Lifeguards<\/h3>\n<p>Water quality is one piece.
